Chicago Storm

High winds last evening and last night were solid across the area. ORD had a peak wind gust of 58MPH.

may very well only be an EF-2 in that case.

91° at MDW today, while ORD got 89'd. ...2024 90°+ Day Tally... 1 - MDW 1 - RFD 1 - ARR 0 - ORD 0 - DPA 0 - PWK 0 - UGN 0 - LOT

Twins in SW. Iowa right now.

Expectation should be that it'll be in a weakening phase as it passes through the CWA.

Really not expecting too much of intertest around here with this. Environment really tails off with east/southeast extent. So much of the guidance that is showing activity quickly weakening as it moves through is probably is correct. SPC is way too overzealous with the enhanced risk.

Best late winter/spring in ages.

Realistic shot at the first 90° day of the year tomorrow? Maybe. Depends on how overnight/morning activity evolves in the region.

That's because this stretch that we're in also had the great record breaking February, something 2012 fell short on (In comparison). So in other words, 2024 February thru Mid-May has had better consistency and longevity in terms of mild/warm temps and nice weather.

A bit late to getting to some of this, so playing catch-up... Chased two multi-mode severe t'storms across portions of Western and Northwestern Illinois on Tuesday, April 16th. Encountered a wall cloud, nickel size hail, 40-50MPH winds, and a gustnado with the activity. A combination of not planning on heading into Iowa, leaving a bit late, and not wanting to deal with the lack of Mississippi River crossings along the Iowa/Illinois border prevented me from seeing any of the tornado action in SE. Iowa. And naturally, the tornado threat vaporized after activity crossed the border into Illinois, due to limited recovery time in the wake of the first round of activity. Chased a supercell severe t'storm across portions of Central Illinois on Thursday, April 18th. Encountered two funnel clouds and 40-50MPH winds with the activity. I really didn't plan on chasing this day, but I was down in C. Illinois for something and activity came close enough for me to mess around with it for a short time. The best part was a close encounter with a rain wrapped couple of supercell t'storm that was overtaken by a QLCS. It gave it a solid effort in producing a tornado in the heavy rain, in a field right across from me just outside of Raymond, IL (Pictured below).

I thought it looked familiar, but couldn't put my finger on exactly which species it was. The majesty palm is somewhat cold hardy, but not as much so as a few other species.

That shit was amazing. Sat out in NW. Illinois from when it cleared ~11:30PM till 3AM. I should have stayed longer too, with a secondary peak 3:30-4:30AM, but I was barely hanging on as it was. Too many pictures to even go through, but hopefully will have a few up eventually.

Will be headed up to NW. Illinois after work later for the Northern Lights, if things are still looking good. That area will have the best combination of the least amount of light pollution and earliest exit of clouds.

Numerous areas are experiencing a few different heat bursts in a corridor from E. Nebraska/Omaha area into N. Illinois tonight, as decaying clusters of showers/t'storms work through. This beneath a nice plume of solid lapse rates and a solid inversion with a deep layer of warmer/drier air just off the deck. MLE out near Omaha is probably the best example I can find, from from 60/46 to 70/33.

The environment around here won’t be bad this afternoon, right under the head of the jet streak and with a small plume of better ML lapse rates. Could have a sneaky decent last minute severe threat across the area for a brief window this afternoon, before things quickly slide into MI/IN.

Wednesday has a much higher ceiling than tomorrow.

don't get ahead of yourself...

it’s hard to tell what the bottom one is, but the top is a needle palm. solid cold hardy palm there.

Tuesday is most interesting on the Euro, if comparing the three OP globals at this range.

CC signature is 1 mile wide on radar.

Moving into populated far west “suburbs” of Omaha now…

SPC doing a shit job per usual today.

I really haven't had time to get into any medium or long range thoughts for quite a while, but... If you're into hyper-active patterns with consistent t'storm/severe t'storm potential and consistently warmer temps, the pattern we are sliding into is for you. One thing to note, though, is that the western/southwestern half of the sub-forum on into the Central US may be favored for the aforementioned. ENS are in agreement on consistent troughing into the PAC NW and potentially deeper into the West Coast, which should allow for a parade of disturbances/storm systems to eject across the Central US. This all begins with the first storm system coming up to end this week, and it may very well continue right on into the first full week of May.

Solid dryline across N and W IL this afternoon. Dew points in the low-mid 50's ahead of it, with mid 20's to low 30's behind it.
