Jonathon Toews (Blackhawks) taken away in ambulance in a car crash in Chicago. Im not sure if weather was the issue in that crash.

[Chicago Storm]

SN has switched over to sleet.

SN has switched over to sleet.

weird, i wouldn't have thought this was a sleet profile.

[HM]

You always have to admire the beauty of Midwest Synoptics in a winter storm. It's like, "guess where the frontogensis is?" lol ...

[turtlehurricane]

weird, i wouldn't have thought this was a sleet profile.

The mesoscale cold pool might've cooled a lower level to below freezing, with the WAA continuing above that.

[IWXwx]

IWX just issued a WWA for their counties adjoining the IN-MI border. Calling for 3-7 along and north of the Toll Road, depending on changeover.

...POTENTIAL FOR HEAVY WET SNOW TONIGHT INTO FRIDAY MORNING

ACROSS FAR NORTHERN INDIANA AND SOUTHERN LOWER MICHIGAN...

.A STORM SYSTEM MOVING OUT OF THE CENTRAL PLAINS WILL APPROACH THE

SOUTHERN GREAT LAKES REGION LATE TONIGHT. INCREASED MOISTURE WILL

LIFT NORTHWARD AHEAD OF THIS SYSTEM ALLOWING FOR INCREASED

COVERAGE OF RAIN EARLY THIS EVENING. RAIN WILL BECOME MIXED WITH

SNOW BY MID TO LATE EVENING...AND CHANGE TO ALL SNOW DURING THE

OVERNIGHT HOURS ACROSS FAR NORTHERN INDIANA INTO SOUTHERN LOWER

MICHIGAN.

THERE IS THE POTENTIAL OF 3 TO 7 INCHES OF SNOW WITH THIS SYSTEM

THE HEAVIEST SNOW IS EXPECTED FROM LATE THIS EVENING INTO EARLY

FRIDAY MORNING...EXCEPT FOR SOME LAKE EFFECT SNOWFALL REMAINING

Heavy snow here last 45 minutes - BIG flakes. Light dusting at this point, but starting to accumulate more rapidly in past 15 minutes.

[Thundersnow12]

from the DVN AFD

THEREFORE LOCATIONS FROM

AROUND I-80 NORTHWARD TO HIGHWAY 20 SHOULD HAVE ALL SNOW BY EARLY

EVENING. SOUTH OF I-80 THE RAIN WILL GRADUALLY CHANGE TO SNOW AS

THE NIGHT WEARS ON. ACCUMULATIONS OF 2 TO 5 INCHES CAN BE EXPECTED

IN THE ADVISORY AREA BUT THERE COULD BE A FEW HIGHER AMOUNTS OF 6+

IF ANY THUNDERSNOWS OCCUR OR HEAVY SNOW BAND PERSISTS. AS THE COLD

POCKET ARRIVES INSTABILITY WILL BE INCREASING TONIGHT. THERE IS

THE POTENTIAL A PART OF THE ADVISORY MAY NEED TO BE UPGRADED TO A

WARNING BUT WILL MONITOR TRENDS.

Iowa somewhere?

[indeedinger]

Iowa somewhere?

Yes - east of Waterloo 20 miles.

[Ottawa Blizzard]

Not looking good for Toronto. I'm thinking 2" of slushy snow max.

[BeastFromTheEast]

MKX axed the advisory for Milwaukee but I wonder if it might need to be reissued. Amounts will be close.

18z RGEM isnt bad for my area..further south than the 18z Nam.

http://www.weatheroffice.gc.ca/data/model_forecast/c32_100.gif

Looks like a decent 4-6" on the latest RGEM ....closer to 2-4" near the Lake.

One 18Z model to the next...you flip flop more than anyone I have ever seen. No offense.

[McDude]

interesting report, some 20-25 dbz returns pushing into the UofC area, kind of surprised they would be snow though.

She said it went back to "spitting rain"

[kevlon62]

Via 290 Wb went from light sleet in Elmhurst a bit ago to fog/mist at Elk Grove Village to fog/snow at Woodfield with grassy surfaces dusted. Car temp @ 36F.

[Thundersnow12]

Anyone with a higher res radar, pretty cool waves/ripples along the northern edge of the E-W snow band in northeast IL. Trying to figure out whats causing that.

[AppsRunner]

Latest hrrr showed 6-8" near the TOL area. I'm skeptical to say the least

Happened this morning. It was dry until around noon.

My only concern--as a Hawks fan--is that the concussion that was reported late yesterday has something to do with his crash this morning. I'd hate to see Toews go the same route as Sid Crosby.

Nothing doing here in Kenosha yet...overcast.

[SpartyOn]

It's a trend that should be noted. That is these slight shifts southeast with every cycle. Don't count it out I guess.

[Thundersnow12]

The HRRR now is even picking up on a subsidence area behind the convection across northern IL later tonight. Can see it in both on the ref and UVV's.

[kevlon62]

At 90 Wb & Rt. 59. All snow falling with occasional moderate bursts.Snow sticking on pretty much all surfaces. We just passed three Tollway plows with blades down flipping snow/slush from paved median and shoulder. Car temp down to 34F. Might we be over the hump?

Loving these shots man I'll be on my way home along a similar path around noon tomorrow so i'll try to grab some similar shots

Definitely an interesting development!

Will County and southern Cook County may find a way like they have all this winter, lol. But yeah, that h7 front is slowing down over the northern areas.

LOT afd rather late

It's been showing something similar on a RA/SN changeover... maybe tssn?
