Chicago Storm

All snow here now, coming down at a good clip and with good flake size. Welcome to May.

Flipping to snow here now. Looks like it''ll be brief, with heavier precip looking to quickly exit within the next hour.

0.26" at MKE thus far.

Snow being reported across the northern tier of IL counties now. Temps steadily falling across NE IL, so there's a good shot ORD ends up seeing some flakes.

These are significant... 0140 PM TSTM WND DMG 2 E FORT WAYNE 41.07N 85.10W 05/10/2020 ALLEN IN PUBLIC WIRES DOWNED, TREES INTO HOUSES. PRIMARILY EAST SIDE OF FORT WAYNE INTO NEW HAVEN. 0210 PM TSTM WND DMG 1 S FORT WAYNE 41.05N 85.14W 05/10/2020 ALLEN IN AMATEUR RADIO 15-20 FOOT TREE DOWNED AT ARCADIA CT. AND HOAGLAND AVE. TREE PARTIALLY BLOCKING ARCARDIA CT.

Even with that length of period, I take it no accums?

Several damage reports down that way as well, so seems valid.

FWA G78MPH with that line of weak convection moving through.

Made it down to 27 here this morning. .

.

Down into the low-mid 30's across NE IL and SE WI as of 1z. Northerly Island is down to 35 as well.

Any snow around here looking doubtful now. .

Looking increasingly likely the following happens... Frost for portions of the area Thur night/Fri morning, freeze/hard freeze for the entire area Fri night/Sat morning, and isolated/scattered rain/snow showers Fri. Then looks like a chance precip ends as snow with the clipper-like system in the vicinity of Sun, before another frost/freeze for the two nights following it. I wouldn't say any record is a lock for this period, but there are a few that will be close...such as the record low max on Fri and record low min on Sat.

Just like that high of 70 on April 25th was gonna be the last 70+ day of April...only to hit 76 three days later, on the 28th. .

Protests over the stay at home order starting up downtown today.

Our in-house magic 8-ball has spoken.

While we are in imagination mode...

2.05” backside rain at ORD. .

1.19" of rain at ORD thus far today.

A period of high winds looks likely from later this afternoon into Thursday morning. Looks like 50-60kts at 925mb edges in along the Lake Michigan shore counties, so will likely end up with 50-60mph gusts for those areas, with 35-50mph more common inland.

The main storm system will really wrap up across the Lakes tomorrow... While early day high temps will be in the 50's tomorrow, temps will likely drop into the 40's the rest of the day, with a lengthy period of rain and wind from late morning into early tomorrow night. Some guidance has upwards of a few inches of rain across N IL/S WI.

Today is going just about as expected, with widespread clouds and convection festering across the main area of focus. Best chance of anything will probably be from that current E IA line, if it matures a bit to the east.

Tomorrow still looks like a low-end risk day. Cloud cover/shower debris issues will be too widespread and significant. Only the HRRR's are interesting.

Tue looks like a marginal-slight worthy risk for areas near/south of I-80 in IA/IL/IN. Beyond that, I had been mentioning elsewhere for a while now that severe chances would likely increase for the Plains/Midwest for first weekend of May into the first week of May...and we have now been consistently seeing signs on longer range guidance that will likely be the case.

Saturday looks like the last day with highs in the 40's for a while.
