The valley funnel hypothesis certainly seems sound. Looks like several tons of effort and knowledge required to make these. Much appreciated

Thank you; I appreciate the kind words!

I live in the northern suburbs of Des Moines and was chasing this beast, and came into the immediate damage path as it past over highway 5 just NE of Norwalk, and some of the trees were partially and others fully, debarked just in the south side of the highway. And of course people were all parked under overpasses just northwest of Norwalk as it was going through the southern parts of that city, blocking the road. I really would love more media and other coverages about the extreme dangers of people parking under overpasses during a tornado, for a plethora of reasons not the least of which includes the blocking of traffic. But this discussion is superb, and well explained!! Historic tornado for sure

Thank you! Since the May 3, 1999, Oklahoma outbreak, the overpass issue has been hammered into public safety messaging, but people just don't seem to get it or care about it. I come across it time and time again while chasing, particularly when a big hail core is approaching. People just park under the overpass and block traffic.

Trey, this was an excellent case study/analysis of that weather event. Going to have to watch a couple times because there is a TON of info! I am sure, after ingesting this, I will have questions. You really are a fantastic meteorology educator as you have a unique way of making meteorology/weather logistics understandable/comprehendible without watering it down as to loose it's significance. It is GREATLY appreciated and stay safe out there!

That’s high up on my list! Might focus on these case studies more after chase season ends, but I do plan on doing more, including 4-27-11.

So much depth and quality going into such a unique tornado event especially only 13 days after the event. Great work I can't wait to see more case studies!

I know this was posted a while ago but this storm event was particularly memorable for myself. I was working at the airport at the time and March 5th and March 6th are days I'll always remember. The 5th, the severe weather which produced this tornado, and then March 6th, we had a surprise snowstorm the day after the tornado. We had a flight divert due to weather on the 5th as well so it was a late night at work that's for sure. Thank you so much for the meteorological dive into this event. You sir get a like and a sub! :)

Thank you so much! Yeah, it was kind of a double whammy for SW IA with the tornado outbreak on the 5th and then the snow on the 6th. Pretty wild weather, especially for March!

Excellent study on this event, I learned a lot of useful information amount that would have been very helpful while actively chasing this event. I managed to get stuck in the conga line behind the Winterset wedge but I was able to break away and catch back up to the storm before is produced the Tama EF2. I would have had some really good, close range video of the Tama tornado but I was alone and testing out a new camcorder that switched back into auto focus on me, ruined all of the video I got. I was on Hwy 63 and it crossed easily less than 250 yards in front of me.

Thank you! Nice intercept of the Tama tornado; we were unable to keep up with it after running into damage in Norwalk. That storm was hauling, so if you fell behind, it was tough to catch back up, especially with the conga line in place.

Another informative case study. Keep them coming! Also, it is wild how that storm in the 412pm picture went to produce that large tornado in such a short time. It doesn't have the look.. Have a good one 👍

We got stuck under the hail core near Orient and one of the haunting things afterwards was seeing all the dead birds in the fields.

Yeah, I’d never seen so many birds on a chase as I had on this day. Figured a lot of them didn’t fare so well.

Dude I've never seen that Joplin footage. Incredible. At the end you could ALREADY see the horizontal vortex!!!

Storms down here in the SE seem to cycle slower. They can push out monsters, but when they drop and pick back up, it usually takes a bit to drop another. Sometimes the same storm in a system will be warned or drop one, then leave that state (say Mississippi into Alabama) go back warned for a while and maybe drop one, then drop one later in Georgia and even into the Carolinas. It’s crazy to see the tornado warning tracks of individual storms across multiple states as they track Northward in Easterly moving squall lines. Long track tornadoes are interesting when studying storm strength, but storms holding circulation across an entire region with minimal major cycling is insane too.

This tornado was showing as directly over my house on the radar… really thought my house would be gone when i got home. it ended up having gone a mile north

When I started watching I was pretty sure this was the tornado outbreak with the tornado that passed by our house. We were less than half a mile from the path the EF4 took in the Newton area. I actually went outside and recorded the sounds after it passed because it was so eerie.

kzread.info/dash/bejne/d6V2s6WJj5qqedo.htmlsi=I9DgpjOvNUsy8rWw I forgot I uploaded it to KZread. Checking the path file from NWS and measuring, it passed 0.3 miles from me (590m). Probably the closest I've ever been to a tornado in my entire life.

This is the tornado that woke me up and scared me to death

Makes me not feel so bad for missing it. We pulled into Winterset about 5-10 minutes after it hit town.

The topography/valley influence on low level winds is a good idea in general but in this area the actual difference in elevations is negligible. The color shading of the topo map gives an exaggerated impression of vertical distance but if you look at the numbers you’ll see they are minuscule particularly in relation to the colossal scale of the atmospheric elements. Overall this presentation is very well done, fascinating and informative. I got in front of this storm east of Des Moines where it was rain wrapped but I could see the upper part of the meso approaching from the SW. The size, rotation rate, lightning, and approach speed was unbelievable for the time of year. I’ve been observing and occasionally chasing storms in Iowa for over three decades and I’ve never seen anything like it. After stopping for less than a minute I rapidly continued south and waited for the storm to pass to my north before following. Unforgettable

Thank you for watching! This definitely was a storm that's rare to see in Iowa in March; felt more like the middle of May than early March. The topographic influence was just an untested hypothesis of mine; you'd actually be surprised at how subtle terrain features can influence the environment a storm experiences. It more so has to do with subtly changing the wind profile to make it more favorable for tornadoes, rather than being minuscule in relation to the size of the storm itself. The Mogollon Rim Convergence Zone I mentioned from Arizona is also a similarly subtle feature with little elevation change compared to surrounding areas, but it's just enough to back the winds near the surface, and as a result, that area has a high frequency of landspout tornadoes and even some supercells given the slightly enhanced low-level shear. But who knows, it definitely is a hypothesis that needs more testing.

@@ConvectiveChronicles Compare the actual elevation changes in feet between Iowa and the other examples. Also, look at historical tornado paths across the region. I don’t think you’re gonna find any correlation with terrain. I could be wrong but I think the only areas where terrain influences boundary layer wind direction (at synoptic or meso scale) would be along the Mississippi and Missouri valleys where elevation changes at the scale of hundreds of feet over relatively short distances.

This video was awesome! Along with Jonesboro and Joplin I think another good analog for that would be Jarrell TX. Do you have any thoughts on Jarrell?

@ConvectiveChronicles

2 жыл бұрын

Thanks so much! As far as the background environment goes, Winterset and Jarrell were quite different. Jarrell was an overall marginal severe weather setup with extremely high instability and very low shear. However, the shear was enhanced by an outflow boundary/gravity wave that originated from an MCS in Oklahoma and Arkansas.

@@ConvectiveChronicles Yeah I just meant that the tornado intensified very quickly. But yeah I read up on it last night. It's quite interesting how a marginal setup became a full-scale tornado outbreak

20:40 thats very similar to the first noodle i saw . driving back from the Dr's (50 miles).... penny hail so hard you could not hear the radio at full blast after it lifted (we pulled over) we saw green clouds...... then a little tiny tornado off to the north of highway 2 . lasted 30 seconds and was gone . . been hooked ever since LOL . . EDIT.... this was in NE montana like, 17 years ago idk we usually get 3 or 4 every year somewhere in the state (one hit billings..... got kinda lucky on that one)

It went right around our house that time
