Chicago Storm

.

Time for record watch... Obviously still have 11 days to go in the month, but given how things have been and will continue to be for the near future, it’s worth watching. As of end of day today, ORD will sit at 2.43” of precip for spring 2021. Driest springs on record for Chicago: 1. 2.73” - 1887 2. 3.20” - 1934 3. 3.87” - 1994 4. 4.08” - 1886 5. 4.17” - 1885 .

Bump. About to roll into late May, and ORD still has yet to have a TS since mid-November of last year. .

A few pics. Forum upload compression ftl .

Spent the past 8 days helping guide a chase tour. We unfortunately didn’t get a tornado, but had high quality storms most days...Chasing anywhere from near the Mexico border to Nebraska. If anyone has ever pondered heading out on one of these tours, do it. It’s one of the best experiences you’ll have...Not only because of the chasing, but because of the people you meet on the tour and along the way, and places you visit along the way. I’ll throw some pictures up later.

Euro was well south at the start, so really neither did well in the end. NAM was bad with handling the snow potential.

It most definitely did change, just not in a way that changed conditions much overall for some areas. Since April 1st, CMH has had 17 days above average and 19 days below average. April precip was 3.28”, which was only 0.12” below average. In the 36 days since April 1st at CMH..... 29 days had a high of 60+, average is 22.2 days. 13 days had a high of 70+, average is 11.6 days. 4 days had a high of 80+, average is 3.3 days. go sit in your corner. .

Someone doesn’t know their climo. .

where is NTXyankee with his daily complaint about how the pattern didn’t change? .

Not really a tornado environment down there today, but instead more of a cold air funnel environment. .

lol .

time to move to the burbs, with a few acres and a lawn. .

definitely not going to get above 70 the rest of the month. .

lol .

Maybe not. Anyone following @andyhb on Twitter knows the situation.

There were numerous brief/weak tornadoes. .

Speaking of droughts at ORD... Still have not officially had a TS since last November.

It is rotating in the mid levels. .

I'm pondering going, but haven't gotten the will to do so yet.

There definitely could be some supercell structures. The best severe potential will likely end up between I-74 and I-72 in W-C IL

The area to watch today is definitely across C IL, as a few others have mentioned. An MCV that has been moving eastward along the IA/MO border this morning will continue eastward across C IL this afternoon and evening. The biggest question for today has been cloud cover, which had been locked in place across the main focus area. However, more recently there has been a growing wedge of clearing pushing northward across NE MO and is now progressing into W IL as well. If that holds, coupled with the MCV and decent instability/moisture/shear, could have a solid threat across C IL this afternoon and evening. We’ll see how it progresses... .

Yea, I’m not sure why they didn’t have a marginal that far north originally on the day 3, and really have no idea why they haven’t brought it north on the day 2. Depending on how things continue to look, might even need a slight risk across E IA/NW-W IL. Best activity will end up west of here, but activity might still have an isolated severe potential when it gets into this area.

Impressive mixing occurring across portions of MN/IA/WI/IL, even more-so than modeled. 90’s have even made it into SW WI. .
