It will be interesting to see how many 90+ days we actually string together around here.

Sat-Mon are a full on lock for 90+, but after that it gets tricky with the ROF potential. The Euro has been consistently keeping the streak alive all week, though, through Friday or so.

i thought that this thread existed already, but apparently it does not.

so, here we go...

The model trend is to keep much of the ring-of-fire storms to my northwest next week.  There could be a band of several inches of rain up there while southeast Iowa and points east and south get nothing but heat.

we all know that the active corridor always ends up further south than modeled.

tomorrow trended doa quickly for around here, with a quick trend towards poor timing of the mcv passage.

shame. we've reached the point where things ramped up for a month of quality activity from mid-june through mid-july last year, after a similarly slow start like this year. it doesn't look like a turn-around is in the cards just yet.

well, in the end the timing improved, but the track still lead to a doa situation.

the convection across the southern plains the night before ended up further south, leading to a further south track of the potent mcv.

Yesterday qualifies as a serial derecho.

Topped out at 92° at ORD and at MDW today.

Wednesday

personally, it would be hard for me to call anything about that convective feedback.

a solidly well defined and strong MCV. the question to me is, will it be boom or bust. we've seen those go both directions over the years.

I'd have to defer to Ricky on this but every model is suffering from convective feedback, I really don't know how to forecast this one. Verbatim most models are significant but there is a feedback that is amplifying the winds, how much of that is true I don't know.

which day?

Topped out at 92° at ORD and at 91° MDW yesterday. Warmest of the season to date at ORD.

The activity that moved through parts of the metro area yesterday afternoon over-performed expectations on what was an isolated/low quality potential day.

The main severe t’storm just missed home by about 2 miles or so, but I took a drive down the road into Batavia and encountered 2.00” hail and ~60MPH winds. After it passed, I drove another block or so down the road and found some 2.50” hail stones laying in the grass. This wasn’t a true big hail, as it was just spiky smaller hail (See pics).

The worst of it all was in the subdivision to the east of where I sat, where 70-90MPH downburst winds occurred with 2.50” hail as well. I drove through this area post-storm, and there were hail piles everywhere, high quality hail fog, shredded trees, and widespread significant tree damage.

Not.  We got a half inch of rain a few days ago and now models are trying to paint a dry bulls-eye over Iowa for much of June.  Another severe-season snoozer.

Scott Sabol has some sort of "What went wrong?" writeup regarding this Spring

LOT confirmed 1 tornado in their CWA from Tuesday's event (May 20th).

1 tornado in IL.

The 2025 LOT CWA tornado count is now 18.

Edit: Also, a landspout tornado was confirmed on May 14th in the IL portion of the LOT CWA, which has been added to the 2025 count above.

What conditions caused the dust storm? I didn't hear about it til after the fact. We had nothing here.

Outflow from the downstate severe storms lofted the dry dirt/dust 

Also, add in that the area it had originated from had missed out on activity with the event on the previous day. 

With the resurging dry/drought conditions lately, it just happened to be a perfect situation that the severe t'storm activity had collapse in that exact area.

spartman broke character?

i didn't have that on my bingo card. but, i didn't have a dust storm on it either.

Friday's dust storm was quite an experience... Never thought I'd ever report a DS at ORD.

Peak conditions...
ORD: DS 1/2SM G50MPH
MDW: +DS 1/4SM G60MPH

Info...
•The dust storm warning for Cook County was only the second ever issued for the county. 
•It was the first ever dust storm warning issued for downtown Chicago.
•Per Frank Wachowski, the last dust storm of this severity in the metro area was way back on May 10th, 1934.

ORD had a high temp of 94° on Thursday, which broke the record high maximum temp for the date of 91° (1962).
