Chicago Storm

that’s the seasonal trend, so lock it in. .

stop wasting time looking at GFS temp plots. .

Usually I'm not big on the long range thoughts as much during the summer, mostly cause I'm out actually enjoying things. However... I did want to mention that it is likely that this active seasonable/trough/NW flow type pattern will stay locked in around the Midwest/Great Lakes for the next week or so. This is partially the product of a generally -NAO/+PNA regime in place on the larger scale. Looks like the next push of hotter temps/higher humidity will be centered around the Aug 19-24th period or so, as the -NAO relaxes and the PNA flips fairly negative.

In terms of this sub-forum, I'd actually be more interested in the severe threat with the MCV across portions of IL/IN on Saturday...more-so that the severe threat with the main storm system on Sunday across the Western portion of the sub-forum. Likely we'll see a solid corridor with flood potential across portions of MO/IL/IN, tonight through Saturday as well.

but it doesn't.

Topped out at 93 at ORD, 93 at MDW, and 92 at RFD today. ...2023 90°+ Day Tally... 13 - ORD 12 - MDW 9 - DPA 9 - ARR 9 - LOT 8 - RFD 8 - PWK 4 - UGN

The flood potential rapidly increasing across Northern Illinois, with all of the training activity.

i never want to see hawkeye ever complain that he's not getting rain, t'storms, snow or whatever...ever again.

so good, it had to be mentioned x3.

93MPH peak wind gusts in Marshaltown, IA (MIW).

Numerous locations in Western and Southern Illinois are breaching 100. Quincy and Macomb are the hottest, at 102 so far.

at least you finally tagged 90.

It's 99 as of noon in Hannibal, MO (HAE).

The only concern I have for the area today is that the backdoor front drives too far inland and too early, undercutting the best goods a bit. Outside of that one concern, all systems are a go with a solid environment.

Topped out at 92 at ORD, 91 at MDW, and 91 at RFD today. ...2023 90°+ Day Tally... 12 - ORD 11 - MDW 8 - DPA 8 - ARR 8 - LOT 7 - RFD 7 - PWK 3 - UGN

A nice overlap of hot temps and high DP's once again today in Western Illinois. It's currently 98/82/122 in Macomb.

And not surprisingly, nothing happened. Timing on the passage of the MCV was just not optimal, a few hours too early.

It's currently 99/80/121 in Macomb. There seems to be an overlap of quality moisture and hot temperatures right around there... Head southwest and it's also 99 in Quincy, head north and there's also an 80 DP in Galesburg.

It’s a race of time right now. A potent MCV continues steadily moving east across S WI. The window of opportunity is fairly short though, before the MCV moves too far east. Shall see how it goes here over the next two hours or so, but a solid environment for severe t'storms is advecting back in, in the wake of the early round of activity.

It's a nice area. Gives me a Midwestern Key West vibe.
