The video opens with a brief weak tornado near the town of Atlanta Kansas and the other large football shaped funnel cloud / wall cloud structure never produced visible rotation on the ground from my perspective.

2 super cells are seen in this video. The larger mothership dominated the atmosphere later in the evening choking off the first storm. There was very little cloud-to-ground lightning considering the size of these storms, however the cloud-to-cloud activity was a fantastic encore to an amazing day of storm chasing in the 2014 season.

WICKED UFO SUPERCELL - Tornadoes, Intense Lightning & Mammatus

Early in the period on this day forecasts suggested a mainly multicellular event with a small chance of supercells and for a couple hours during the late afternoon, small cells struggled to develop. At 6:35 the struggling cells congealed into a messy multicell storm cluster with two organized rotating updrafts and like most of these scenarios, the tail end updraft strengthened and dominated.

After a couple tornadoes an ITENSE barrage of cloud to ground lightning strikes ensued. During waves of peak activity, lightning was striking the ground about every 2 to 3 seconds.

At one point it appeared there was a large powerful tornado developing but upon closer inspection you'll see that the thick gray mass touching the ground was a burst of rain falling through the mesocyclone rather than a column surging upward. Still, rotating winds sculpted this rain shaft into a wedge shape suggesting that what we were witnessing might have been a tornado by definition, but rather a nebulous weak one.

And then the headliner took the stage! Unreal scyfy structure and a beautiful greenish hue presented an epic wind sculpted masterpiece. The supercell motion was almost stationary and the hovering mesocyclone resembled an alien mothership UFO. During this time another brief tornado touched down.

I remember chatting with a Western Kansas farmer one May afternoon and warned him there was a storm heading his way capable of producing tornadoes. He responded I'll take ten of em... The odds of a tornado striking one's home is extremely small even in Western Kansas. A much more rational threat to a farmer is drought.
Blue skies yield a dark cloud of worry over farmers for a drought induced crop failure can economically ruin a hard working family.
Locals near Leoti Kansas got their rain and as the sun set, they were treated to a magic hour encore of color followed by a psychedelic lightning show. In all, 3 small brief tornadoes were witnessed and no destruction.

Hail Storm Freaks of Nature & largest hail stone ever recorded recreation

Extensive footage of giant hail stones and hail storm facts plus the largest hail stone ever officially recorded recreated. Damaging softball sized hail, sideways flying bullet hail and complete summer white outs are a few highlights in this stock hail footage video. For licensing contact
HAIL FACTS & Interesting information...

1. Hail injures about 24 people per year in the USA
2. The last hail related death occurred in Texas in 2000 after a man got struck in the head and later died of head trauma.
3. On average, hail causes almost a billion dollars of damage to crops each year in the USA
4. Hail storms killed 246 people in India on April 30, 1888
5. The largest hail stone officially measured landed in Vivian South Dakota, July 23rd, 2010... It was eight inches in diameter and weighed almost two pounds.

Hail stones crash through windows, they shred trees and crops, pummel live stock, damage roofs, wreak havoc on cars, and everything underneath its wrath. Hail can turn a scorching Summer ground into a winter wonderland in minutes. Sometimes softballs just fall from the sky. Other times strong winds hurl hail stones sideways like bullets. If you're caught away from shelter during a severe hail storm, you've got a problem. If you're a storm chaser, Hail is your nemesis.

A Hail stone forms as a tiny super cooled water droplet journeys up above the freezing level in some of the most beautiful and dramatic thunderstorms.

In an environment conducive of a severe hail storm, this rising air, or updraft is often exploding into lowered freezing levels.This is the factory where hail is made. When the super cooled droplet freezes, the process releases heat which keeps the stones exterior in a sticky liquid phase. As the little stone journeys up and down and through the cloud it captures more snow and water on the surface... Molecules near the inner layer freezes, and the hail stones grows another layer.

Hailstones can also grow by colliding and conglomerating with others... One of the reasons they come in such myriad of odd shapes.

Upward winds sustain ice pebbles and the longer they hang around up there, the larger they tend to get. Updraft winds rising at say 40 mph, are easily strong enough to sustain hail the size of dimes or quarters... But some intense updrafts blow up over 100 mph. This is where things really start to get freaky.

Eventually, the weight of the hail stone overcomes the updraft winds and it falls to Earth, often appearing as bright white curtains. Isolated thunderstorms with hail downdrafts set the stage for the most vibrant rainbows. If the storm matures into a high precipitation monster, the thick hail core often has a breath-taking turquoise glow. And because these storms often occur in the late afternoon through evening when angled yellow sunlight blasts into the hail core, the yellow and blue make green... And that's why people associate green storm clouds with tornadoes. Strong inflow winds that inhale dust can also add a yellowish filter over the blue core.

The thought of getting trapped under an intense tornadic hail storm can be frightening, but not nearly as terrifying as the thought of having to sit out a day or two replacing glass while your buddies are out bagging photogenic tornadoes.

Often the same powerful updrafts that create giant hail, drop tornadoes. These storms are called supercells. These storms do everything they can to detour storm chasers... They cover the road in ice so you cant drive fast... then they cover the roads in wet slippery leaves so you cant drive fast. If that doesn't work, they drop buckets of hail to reduce the air temperature to the dew point causing hail fog... And of course if that doesn't slow you down, they break your windows.

Most chasers just avoid the hail cores often revealed on radar with a pink or purple spot. Other chasers would rather sacrifice portions of their view with metal hail guards and shields to block the icy shrapnel. Others have the luxury of thick super heavy duty glass to shoot through.

Top 10 best tornado video countdown. Tornadoes manifest themselves in all sorts of shapes and sizes. Some are a wondrous bright white, others are dark horrific, monsters. Most are harmless grazing over rural farmland, others are worst case scenarios. I've been chasing tornadoes since 1999 and these are my top ten best tornado videos.

Tornado Sound:
The roar of a tornado sounds different depending on it's size, how close you are and what the tornado is striking. Ones I've heard over open fields often sound like powerful waterfalls. The bigger the tornado, the louder and deeper the rumble. Ones moving through trees get louder and can sound more like a jet engine. In town, where there are lots of homes and buildings an approaching tornado might sound like a freight train with the clickity-clack noises of airborne missiles and heavy debris slamming into your neighbors homes.

#10 on this countdown was an extremely close, stationary tornado twirling 50 yards in front of my vehicle.

#9 The El Reno Oklahoma on May 31, 2013 was the widest tornado ever recorded. Mobile doppler recorded 295 mph winds just above the surface as this tornado grew to a record breaking 2.6 miles wide. The tornado occurred over mostly rural farm. Because the most powerful winds did not strike any anchored structures, this tornado only received an EF3 rating.

#8 was a beautiful, white, shape-shifting EF4 tornado descending from a tight, high base near Alpena South Dakota on June 18, 2014.

#7 and # 6 belong to the Pilger Nebraska twin tornadoes that touched down on June 16, 2014.
Two tornadoes on the ground at the same time isn't common, however two almost identical powerful EF4's in close proximity is extremely rare.

# 5 occurred in Cedar County Nebraska on June 17, 2014. This violent tornado occurred over mostly open farm land and received a underrated EF3.

#4 touched down just south of Dodge City Kansas as two mesocyclones buckled into each other like gears. This storm was a long lived cyclic supercell responsible for dropping a dozen or more tornadoes on May 24, 2016. For most of this tornadoes life, it shared the stage with another nearby tornado and at one point three tornadoes were on the ground at the same time.

#3 was a long lived, extremely violent tornado touching down near Chapman Kansas or Abilene Kansas on May 25, 2016.
For ninety minutes this finely tuned machine was on the ground. Unbelievably, this breath taking EF4 did not claim any lives.

#2... If ever a thing haunts your dreams, It might resemble the remorseless Katie-Wynnewood Oklahoma tornado of May 9, 2016. In seconds this EF4 ripped entire roof off its walls and tossed its fragments a hundred meters into the air. The rest of the house demolished. Trees hovers above the ground while roof trusses and 2x4's whirl around the tornado like feathers and a man looses his life.

#1 takes us back south of Dodge City to that unprecedented day, May 24th, 2016. At least a dozen tornadoes touched down, but the first one was the ultimate beautiful tornado. For approximately 30 minutes this slow moving, perfect beauty presented the tornado of a lifetime up close! Well lit excellent conditions, with good roads provided a dream come true scenario for even the most dedicated veteran chasers.

Supercell Thunderstorm/Rapidly Rotating Wall Cloud- Amarillo, TX June 11th, 2005

August/September 2013 Update: Ever since YouTube has implemented the 144p default option, many videos here on YouTube look horrible and very pixelated upon buffering. It's also extremely hard to change to a better resolution, many times if you try to change it, it doesn't take and the video still plays at 144p, even if the resolution is already set to 360p or 480p! If you are having this issue with my video here, as some have had, here is the fix for Firefox at least. The plug-in installs in just a few seconds, and then all you have to do is choose what quality you want the videos to default too when you watch them. You even get a few other helpful options too! Hopefully YouTube will address this issue soon which has caused widespread problems with several videos here on my channel, and on many other channels as well.
See link for the fix:

This video was shot during our quick fly out/fly back home spot chase of June 2005. The month prior we completed a successful two weeks on the road, but we still wanted more storms. So, during the second week in June, the pattern started shaping up for another bout of severe weather, and that's when Dave Lewison and I booked a flight out to Denver on Jet Blue, and headed out for another few days of chasing. No tornadoes we spotted during this trip, but we did see some amazing storms none the less. This one being the best of them.

Hope you enjoy the video, and please rate, comment and subscribe if you have a few moments as I will be posting many more videos over the coming days/weeks/months. Thanks!!

The 2nd day of our 2016 storm chase trip, and yet another day filled with large hail and supercell thunderstorms. This particular supercell formed near the town of Big Lake, TX and put out some incredible amounts of hail, along with hail fog so thick, I was barely able to drive more than 15mph. The video actually ended up picking up more than I could actually see with my eyes at the time.

MASSIVE MILE WIDE TORNADO Heading for Oklahoma City Metro !!!

Incredible mile wide tornado causes EF3 damage near Oklahoma City and incredible close footage of a stationary tornado near New Castle. for licensing contact
At 1:25 PM a tornado watch was issued and by 2:50 PM, a small isolated thunderstorm was already producing several funnel clouds 60 miles southwest of Oklahoma City.
Powerful positive lightning activity was increasing near a classic merry-go-round base and a tight tornado briefly twisted to the ground. The storm was intensifying and the broader picture revealed a loaded gun scenario with Oklahoma City in its cross heirs.


The tornado cyclone circumference was expanding and funnels were writhing inside its curtains like a cage full of snakes

The RFD or Rear Flank Downdraft is a key mechanism in the formation of tornadoes in supercells and may include intense wind, rain and hail surging from the backside of the storm.

When storm chasers see strong wind and rain recirculating back into a developing tornado, they know it means trouble.

In this video a classic scenario of a powerful rear flank downdraft obscures an intensifying tornado in seconds. Unfortunately many people drive through RFD walls of rain only to meet their demise on the other side.

Strong RFD's can blow out windows and overturn vehicles. Large tornadoes can and often do change direction so driving through a powerful, blinding Rear flank Downdraft is a highly dangerous gamble even for veteran storm chasers.

A mile wide tornado causing EF3 damage struck Bridge Creek Oklahoma, a small suburb less than 15 miles from heavily populated Norman.

Another unrated tornado developed near New Castle Oklahoma and remained stationary for several minutes before quickly dissipating, then the parent storm moved into Norman. The police were shut down streets and interstates while the city prepared for the worst.

A confirmed EF1 tornado damaged west Norman. This storm would drop a couple more weak tornadoes in the Oklahoma City Metro area before transitioning into a high precipitation mess causing flooding. The Bridge Creek EF3 tornado tracked over 10 miles before stalling prior to entering a heavily populated area. Oklahoma City Metro dodged another bullet and could exhale in relief... but not for long... A new tornadic supercell would fire to the southwest and train over the previous storms path. It would enter Oklahoma City after dark and drop a destructive EF3 tornado injuring 12 people.

Hurricane, Tornado, Cyclone – What’s the Difference?

What is the difference between a tornado and a hurricane? And what about typhoon? First, let’s get it straight: all these weather phenomena have to do with strong winds. Not my-umbrella-got-torn-from-my-hands strong, mind you, but rather my-house-got-blown-away-to-the-Land-of-Oz kind of thing. Yet before we get to the actual difference between hurricanes and typhoons, we must understand that they’re one and the same thing called a tropical cyclone.

If you live in moderate or colder climates, there’s nothing for you to worry about, even if your house is right by the seaside, because you’ll only hear about cyclones from the news. After all, they’re called tropical for a reason: they only form in tropical or subtropical areas, because they need warm water to get things going.

- A tropical cyclone is a huge mass of clouds that gather in the sky and start rotating counter clock-wise due to very low air pressure.
- Cyclones occur much more often than you think! But only few of them grow large and strong enough to become hurricanes or typhoons.
- The weakest version of a tropical cyclone is called a tropical depression. It’s a similar swirling mass of clouds, usually accompanied by storms, but the force of winds in it is not very high.
- When the winds are stronger than 39 mph, the cyclone is then called a tropical storm. This is a more serious threat, and you’ll do well to hide inside your house because gusts of wind might reach 72 mph.
- And only if the wind gets even more powerful than that, then it can be called a hurricane or a typhoon.
- If a severe tropical cyclone with wind speeds of over 75 mph occurs in the North Atlantic or North-East Pacific, it’s called a hurricane. If it’s in the North-West Pacific, then it’s a typhoon.
- We hear more about hurricanes than typhoons because the Atlantic Ocean is warmer than the Pacific, and warm water acts like a fuel for cyclones.
- Tornadoes can form almost anywhere they please, both over sea and over land. But there’s much more to it than that.
- A tornado is a swirling funnel of air coming down from the sky. It appears during thunderstorms, and it’s rather a consequence than a reason for severe weather.
- But despite its terrible power, a tornado is a very local event, and short-lived at that. The biggest one ever registered by scientists was just over 1.5 mi in diameter and lasted about an hour or so.
- The center, in its turn, is usually calm and windless — so calm, in fact, that it’s almost creepy. It’s called the eye of the tornado or the hurricane, and it’s basically the safest place to be when the phenomenon comes to you.
- There are 5 categories of hurricanes according to the National Weather Service. Category 1 is just slightly more intense than a tropical storm, and in some countries it’s still considered as such.
- Category 2 is another story altogether. The wind blows at speeds of up to 109 mph, and that’s where the real trouble starts.
- When a hurricane grows to Category 3, it’s already a disaster. First of all, it’s big. Secondly, it’s powerful. The winds are reaching 129 mph, and catching such a gust is like being hit with a race car.
- A Category 4 major hurricane is something you don’t want to see with your own eyes. With gusts of wind up to 157 mph, it can tear trees from the ground and hurl fairly large objects in the air, causing lots of damage.
- And finally, a Category 5 major hurricane is a thing to be avoided at all costs. In other classifications it’s even called a super typhoon or a super cyclonic storm, which says a lot.

Mothership Supercell near Adrian, TX - 21st May 2012 Storm Chasing Vlog

Analysis of the storm from The Weather Channel:

More video footage of the supercell filmed by our tour director, Bill Reid:

The company I toured with are called Tempest Tours. I would HIGHLY recommend them if you are interested in doing storm chasing. I enjoyed it so much that I am booked to do another tour in mid-June.

Horrific EF-5 tornado in Moore, Oklahoma: May 20, 2013

Coming on the heels of the highly destructive May 19, 2013 severe weather event in central Oklahoma—which included strong to violent tornadoes in the Edmond, Carney, Wellston, east Norman, Bethel Acres, and Shawnee areas—May 20 began as yet another day with an atmosphere primed for explosive severe thunderstorms in the southern Great Plains. Still, despite everything we understood about the potential that day, what we ultimately experienced was hard to accept. It still is.

Early in the afternoon, a supercell thunderstorm erupted in a region of extreme instability, along an outflow boundary leftover from the previous day’s storms. This storm very quickly became tornadic, with an initial tall, sharp-edged, cone-shaped tornado forming over the town of Newcastle—another central Oklahoma town with its own history of damaging tornadoes. As experienced storm chasers, we instantly recognized that the tornado was likely very strong, even while initially observing its slender, early stages from several miles to the east; as Cleveland County residents who are very familiar with the geography of southwest Oklahoma City and Moore, we were immediately concerned that we were about to witness yet another tornado tragedy for our community.

This is an extended, near-continuous sequence, beginning with the tornado’s initial touchdown in Newcastle (observed from a distance of approximately 7 miles). We approached the tornado from the east, along Indian Hills Road, and eventually turned north onto Pennsylvania Ave., where we observed the large, wedge-shaped tornado for approximately 10 minutes, as it moved from McClain County, across the Canadian River, and into southwest Oklahoma City and western Moore. Eventually we moved farther north along Penn., and turned east onto 164th, where we came within approximately ¼ mile of the tornadic circulation. This was an incredible vantage point for observing this very violent tornado’s ground circulation, and especially for experiencing the tornado’s otherworldly roar, but it was also a particularly dangerous position to be in, given the tremendous amounts of debris being ejected from much higher up in the storm. Roofing material, sheet metal, and siding were continuously raining down around us, along with insulation and other smaller debris particles, as we flanked the tornado for several miles along 164th.

What we were experiencing was quite apparent; Dave’s earliest tornado observations include May 3, 1999, and May 8, 2003, and we are both well versed in the subject of historic, significant tornadoes. This was also not our first EF-5. This time, though, friends were suffering serious property damage; businesses we frequented were in danger of being destroyed; and, schools were being leveled while children were inside. We dropped the storm at I-35, wanting nothing more to do with it as we realized the terrible devastation unfolding, yet again, in a community we knew and loved.

UNREAL TWIN TORNADOES & Bead Lightning Strike

Two large tornadoes touching down simultaneously. For licensing contact

Many tornadoes were observed under one storm with two separate rotating updrafts. At one point the smaller twin tornado eclipsed the larger tornado as a beaded positive flash lightning bolt emerged out of the side of the larger tornado.

Striated Supercell and Rotating Wall Cloud Sterling City, Tx May 26, 2014

After experience some weak rotation during the initial stages of the storm, we were later treated to a beautiful, clean, striated upgrade as the supercell approached Sterling City, Tx. A few hours later we would be inundated with large hail as another storm passed directly over top of us.


Simple answers to... How do you see a tornado on radar and how do you know if a tornado is coming toward you?

When the cross section of precipitation makes a hook shape, or a hook echo, we can infer strong rotation and possibly a tornado.  Precipitation is revealed in the reflectivity mode on radar apps.

In Reflectivity mode, some of the beam emitted from radar is reflected back to the radar by rain, snow or hail and detected. That’s why we call it an echo. 

The greatest reflectivity comes from hail stones displayed in pinks and purples and the smallest the more tiny hydrometeors like light rain and drizzle in yellow or green.

Not all tornadoes form a hook echo o radar. That's were Velocity mode comes in. Velocity mode is like X-ray vision. 
It’s a POWERFUL tool for detecting circulations within a storm.  
Red indicates wind moving away from the radar, and green toward the radar.   A relatively small concentrated area of inbound and outbound stronger velocities coming together indicates strong rotation and possibly a tornado. Together, Reflectivity and Velocity are powerful tools for detecting tornadoes. 

Tornadoes often change direction and the scan you are viewing could be several minutes old. Also factor in, the circulations depicted on radar can be several kilometers aloft. And the tornadoes position at the surface can be displaced as it bends diagonally through the storm.

Many radar apps like Radarscope have a storm tracking or cell motions option. You can also get a good idea of what direction the storm is going by playing the animation loop.

Some radar apps also offer lightning data. Most of the time lightning data is a good tool for tracking lightning and predicting storm intensity.   I assumed they are all lightning data is detecting cloud-to-ground lightning strikes, but to be honest, there are many times when I’m positioned in a sea of would-be lightning strikes according to the data, and I’ve observed no CG’s near my area.  So perhaps they were false signals or large intra-cloud discharges were detected? I’m currently looking into this mystery. 

On May 1st, I witnessed my first tornado of 2018 near Salina Kansas. Watch how I use radar to track the tornado.

LARGEST TORNADO EVER!!! From Birth to Death (w/ Radar & Commentary) 5-31-13

At 2.6 Miles wide, this is the largest Tornado ever recorded. Touchdown was near El Reno Oklahoma on 5-31-13. This tornado was very deceptive to many due to its appearance and size. The bulk of what you are seeing at 2:50 is a large wedge tornado. When the base lifts and flattens at around 3:05 it gave the tornado a mesocyclone appearance and when it started dropping large sub-vorticies many chasers lost sight of the big picture. At around 6:02, the tornado is taking up almost the entire frame, however the huge sub-vorticies to the lower right appear to be the only point of ground rotation. What many thought were several tornadoes was in fact just 1. At time code 6:30, this is a separate, smaller anticyclonic tornado.

This 2.6 mile wide tornado received an EF3 rating... There is an intermediate circulation between a mesocyclone and a tornado called a tornado cyclone. Often the lines between these features are blurry. When this tornado first touched down it took on a classic wedge shape, but then the bottom truncated or flattened out and the wedge transitioned to a tornado cyclone. Under the tornado cyclone if you look closer you'll see a brief smaller tornado or two touch down.. these are suction vortices. Underneath this flat truncated tornado cyclone, almost invisible winds are causing damage on a the scale of a weak tornado. Therefore, the entire area underneath the tornado cyclone is by definition a tornado. The majority of this tornado was only causing EF1 damage, however the highly powerful suction vortices packed winds well over that required to cause EF5 damage... except these most powerful winds never hit any structures to cause the damage or indicators to warrant giving this tornado an EF5. The thing to realize is that tornadoes by definition are not always condensed with clearly visible borders. When I was retreating the circulating winds were blowing the lighter back of my car out from under me. Other storm chasers got rolled, others took direct hits.

CORRECTION: The SPC does not give Tornado warnings.

We are all aware of the risks chasing tornadoes. The surprising thing to us was that none of us had been killed yet, and even more surprising was that when it finally happened it happened to Tim Samaras, his son Paul and Carl Young.

Earlier that day the Storm Prediction Center gave the public a Loaded Gun warning for Oklahoma City and surrounding area. Unfortunately this also tells everyone in OKC where there's an excellent chance of seeing a destructive tornado. The streets and back roads were packed with cars and trucks, half evacuating, half racing in. People were hollering, cursing, crashing into each other, panicking, and blocking passage. Horns, sirens, thunder and the gushing sound of a tornado barreling down. At first the storm was moving relatively slow in an Easterly direction. 2 or 3 miles to the South was the Canadian River where most of the backroads / escape routes ended. Straight ahead were several easterly roads heading to OKC. When the tornado materialized i was driving next to it with several other chasers about 25 mph as it inched closer and closer. When it was close enough i hit the gas planning to outrun it. The tornado's radius was growing, accelerating and getting closer.... I could only go so fast due to the traffic in front of me and the tornado was gaining ground. I slammed on the breaks flipped the car around, blasted west and had to drive closer to an EF-5 than i ever want to again... looking at my maps i could see the chasers might be outrun. Then the tornado made a hard left turn to the Northeast and grew to 2.6 miles wide in diameter.

If i had to speculate I'd say something random happened to Tim. Somebody ran him off the road or crashed into his vehicle... or some kind of vehicle failure... Tire blow out or windshield gave way... He knew tornadoes tendency to deviate. We may never know, but i'm convinced something else went wrong. Regardless, They died doing what they loved doing and if it happens to me... if i start choking on a peanut while running from a tornado know this... it was worth every second. I love chasing tornadoes and i love cracker jack. My condolences to Tim, Paul and Carl's family and all the other victims of this day. I was looking forward to Tim's lightning research.

Storm Chase Case | Needmore, Texas Tornado Warned Supercell | May 4, 2019

Here's a new experiment for our channel and I hope we can continue to evolve and develop this content type. Today, we're doing a start-to-finish storm chase case with some thoughts on forecasting, strategy, and storm anatomy throughout. The hope is these become an all-encompassing source of learning as we move forward.

So with this case, we're taking a look at one of Sanner's only supercell storm days of 2019 but also a good marginal looking supercell day that garnered a slight risk of severe storms and marginal risk of tornadoes from the SPC. Days like this, where there's just enough for supercells, are incredibly fun to chase when they work out because typically the storms are more isolated in nature and they can tend to be beautiful and slow moving.

The target today is either the mountains of SC New Mexico or a developing confluence line in eastern New Mexico.

A few key takeways you should take from this chase case are:

1-Never sleep on supercell days. Even when they seem otherwise marginal, if you are a fan of storm structure and photos of storm structure, these marginal supercell days can really be great. This is especially true as you get into May and June and onto the High Plains.

2-Another is that wall clouds don't mean tornadoes are imminent, especially when they aren't persistent and rotating. Lowerings under supercells are common, but its the persistence and rotation that set the tornadic ones apart (but even those aren't guarantees!).

3-The last one is to always keep your options option with targeting as much as possible. This is an interesting topic and we've touched on it in our Storm Chase Forecasting series ( but hedging to keep as much of a target region open as long as possible is a really smart move unless the target is super obvious.

Hey did you like this? Should we do more? Let us know in the comments and of course, be sure to subscribe!
