Chicago Storm

It's official... The NAM, 3km NAM, SREF, HREF and HiresW will all be discontinued on Aug 31st. The RRFS and REFS will be implemented on the same date. The HRRR and RAP will survive for now, but they're on borrowed time.

Just got back from guiding a storm chasing tour over the past week. Easily the worst stretch I've experienced since I started doing these back in 2021.

April 2026 finished as the 7th warmest April on record in Chicago.

Hi @Stebo

Peak wind gust of 67MPH at ARR yesterday afternoon with the wake low, just down the road from home. Had isolated to scattered branches down around town. ORD had a peak wind gust of 54MPH.

Nothing has really changed. Globals have showed a messy look more often than not for days now.

he's literally the same as he's always been.

Reports from scanners, some local residents, and some news sources say yes. Local sheriff says no. Wait and see I guess...

4 fatalities in Lena, IL.

Timmer got a big rain-wrapped wedge in NW IL.

i'd argue a solid moderate risk area will end up being needed/verifying for wind and qlcs tors. sometimes the spc forgets that their forecasts are coverage based.

ORD had a low temp of 62° on April 13th, which tied the record high min temp for the date of 62° (1941). ORD received 2.43" of precip on April 14th, which broke the record precip total for the date of 1.21" (1949).

Chicago/O'Hare had a low temperature of 62° on April 13th, which tied the record high minimum temperature for the date of 62° (1941). Chicago/O'Hare received 2.43" of precipitation on April 14th, which broke the record precipitation total for the date of 1.21" (1949).

first cap bust of the season around here. hate to see it.

Looks like the airport was RFD'd, with the couplet having moved just a hair north.

The Madison area was murdered by hail.

initiation in IA. spc gonna wait till they are tor-ing to issue a watch?

it's a sup day, even around here.

They should. The ENH also needs to be greatly expanded as well, as that secondary zone of interest further south ( C IL) is gaining steam.

the spc has 50 million types of hatching now, but somehow still couldn’t figure out how to put one across the area for hail today.

for the winter folks...

It was mostly advection driven destabilization.

i'll say, for someone who used to work outdoors, this would have been chalked up a good spring in my books.

it's giving it a go as it approaches you.
