Overachieved a bit this morning with I think three rounds of severe-warned cells moving through southern Wisconsin. Shouldn't have been a surprise, really. SPC would have done well to leave the slight risk they introduced with the first Day 2 yesterday in place, or at least leave the entire area in a marginal instead of just the eastern half. Several reports of wind damage, especially in Rock County. Not all of them have made the LSRs on SPC's page, yet.

Was about to post on this but then got super busy at work (live severe wx cut-ins among other things). Interesting tension among first whiff CAM solutions...3K NAM has a rather volatile environment over S WI/N IL at 00Z Friday Saturday, but no convection. FV3 meanwhile has a huge derecho blowing through.

Ah. That was a classic Lieowa day. I was chasing out there in the 15% hatched / double-digit STP bullseye, but it blew up into an insta-squall.

Southern WI removed from the slight risk on the updated Day 2. Lame, but could see it coming based on the model trends. Amazing how literally everything this year has skipped us, except for 3/31 when I was in Iowa going after the bigger fish ( ). Sent from my Pixel 4a using Tapatalk

That *is* a pretty powerhouse system being depicted on the NAM. Not too often you see tornado-favorable soundings valid for 15Z (10 AM) in this neck of the woods.

Need that system to either slow down or speed up by 12 hours.

Yeah. They said it was mostly gonna stay aloft... I didn't check a whole lot, but I didn't see an AQI number on my phone today like I did for several consecutive days during the really bad smoke outbreak almost a month ago. Edit: There is one on there; just saw it tick from 160 to 161.

Yes it's the tail end of its range but the latest NAM for Thursday evening is...interesting. GFS has hints of the same general system for at least the last couple of runs. Of course the crucial details of the convective environment are gonna be all over the place at this range/at this time of year.

Lucky you.

Fairly p***ing rain on the southwest side now. Airport might not see much if anything out of this.

Nice little rumbler rolling through right now.

Not really. The couple of days in late June it was thick enough for me to smell on the ground here it smelled like burnt plastic, not like a campfire at all.

Here's another frame grab from about 30 seconds later, at Silver Glen Rd. & Denker Rd. The closer/southern twin had appeared to lift (at least in terms of the condensation funnel) but those cloud tendrils were still spinning wildly. Meanwhile it's probably my best glimpse of the Plato Center-Elgin EF1 toward the left. Two concurrent cyclonic tornadoes from distinct mesocyclones in such close proximity, one of those things that seems to defy the laws of physics (except, Pilger happened). That's the amount of low-level shear that was present over the Chicago metro on Wednesday.

Literally slept through the southern Wisconsin tornado warning...we weren't even in a marginal risk until the 01Z outlook.

Near-constant thunder in Madison now. Between yesterday and today, Goosebumps Girl's prayers are being answered after the last 90 days of absolute dog shit.

Cow!

It's interesting; if I'm not mistaken 1994 was considered a possible analog to this year; it likewise featured a very slow "traditional" severe weather season of May through mid-June in the Plains, followed by an anomalous "post-season" uptick in activity that continued well into the summer. Meanwhile the Midwest has brought two of the best regional tornado chases of my life in 3/31 and 7/12, but with scarcely a rumble of thunder (or drop of rain) in between.

"Full" video, such as it is (all 60 glorious seconds of tornadic bliss) is up:

Is there even any point to SPC doing convective outlooks beyond Day 1 in July/August?

Great shot, Matt! Jealous. That was a weirdly structured storm. One of the reasons my view wasn't so good was because I kept trying to hug the southern flank where it would periodically look like a hook was trying to form. However the couplet was way off to the north, I assumed it would be buried in rain but it wasn't.

Yep, glimpsed that one but was a little too far away, too many trees lining the roads. If I wanted that I'd chase in Wisconsin! Actual grab instead of phone photo of my camcorder screen. Unfortunately only got a few seconds of usable video. It was also hard to keep up with the storm, despite the warning text saying it was moving at 35 MPH and I was mostly able to keep to main roads at 45-50 MPH and had pretty good luck with the traffic lights, I never seemed to gain any distance on them. Gave up at Bartlett Metra Station. I think the train video I took there is longer than my tornado video will end up being. This is from Silver Glen Rd. just east of Corron Rd., north of Campton Hills.

This was fun. Of course it waited until it was in the trees and then the burbs to produce, but this is why I stuck with it. Sent from my Pixel 4a using Tapatalk

Looks like a cell has fired just WNW of here. Wasn't a lot of time for sunshine, though. Maybe @Chicago Storm was right. Gonna give it some time, though as impatience has burned me in the past (most notably 4/9/15). Sent from my Pixel 4a using Tapatalk

Sun coming out in Davis Jct. Warm front must be here. Sent from my Pixel 4a using Tapatalk

Gonna sit tight in Davis Jct., IL for a little while. Sent from my Pixel 4a using Tapatalk
