Tail end of the range of course but NAM went bonkers with the EHI/SCP over northern Illinois on Monday. CAPE so fat it's gonna need to call Dr. Nowzaradan.

12Z runs came in a bit hot for Monday-Wednesday after waffling some starting shortly after I made my previous post (go figure). We shall see.

@ldub23 is a known tropical troll and king weinerhead. He downcasted 2017 hard like three days before Harvey spun back up and did what it did to Texas.

SPC starting to come on board: Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0346 AM CDT Tue Jul 23 2024 Valid 261200Z - 311200Z ...DISCUSSION... Upper ridging will spread across parts of the Plains and eastern states, while the subtropical high develops westward over the southern tier of the U.S. during the Day 4-8/Fri-Tue period. This will suppress severe thunderstorm potential for much of the CONUS. The exception will be a potentially more active period for parts of the northern Plains into the Upper Midwest due to a series of upper shortwave troughs migrating across the Canadian Prairies and parts of the northern Plains/Upper Midwest through the forecast period.

GFS has been teasing the next possible uptick in severe potential for the Midwest for the end of the month for a while now. Modest to moderate WNW to NW 500mb flow over 70s dewpoints. Signal is still there as of today's 12Z run, but it's still 7-8 days out so obviously much TBD regarding timing, location, mode and ceiling of threat.

Currently getting drenched in southwest Madison. Close CGs and loud booms, too.

Evansville from 7/15 now confirmed as a 1.23-mile EF0 path. https://www.weather.gov/mkx/wisconsintornadoes We've now edged out 2021 as the busiest year for in Wisconsin out of the last 11. Still behind 2010 with 46, and 2005's record of 62 is probably safe barring a surprise August outbreak (which is also what put that year so far ahead of everything else). Still haven't had one rated EF3+, though and the longest track by far was Evansville-Lake Koshkonong on, go figure, February 8th.

@Chicago Storm's reply:

Yeah, agreed cool drought is the worst, but was stoked for a 1995-esque "hot and active" and we just haven't gotten there.

Here in Madison we were on the very northern fringe of Monday's complex; no severe weather (and barely any rain, which is fine given how much we got in the preceding couple of days) but like on June 24th, the setting sun combined with the departing storm clouds illuminated the whole sky pinkish-orange, as intracloud lightning flashed. Some people with a view to the east even caught the lightning with a large, horizon-spanning rainbow.

Kieler damage was indeed an EF1 that touched down for 1 minute (so not as strong as I thought). Evansville not confirmed despite how low to the ground the funnel looked in the video.

Pretty substantial structural damage at a supper club and a few nearby buildings near Kieler, WI. Wouldn't be surprised if that turns out to have been a brief but strong spin-up. Also at work we have viewer-submitted video of what certainly appears to be a tornado (although it wasn't tagged as "confirmed" at the time) near Evansville (same town that was affected by the record-breaking early February EF2).

Surprised none of 4/9/15, 6/22/15 and '16, 8/9/21, 3/31/23 or 7/12/23 topped that list.

Looks like possible tornado just north of Stockton, IL.

Earlier northward trend to the HRRR runs seems to have been a mirage; will get clipped at most here in Madison, and that only if that northernmost "kink" in the bow over Lafayette/Green Counties can surge northeastward.
