1/24-1/25 Major Winter Storm - S. IL, IN, and OH

[Jackstraw]

Almost 2in here. Winds light with some gusts buts enough to blow this stuff. Dime-Nickel flake size. Some 1 footers out there already. Country roads have drift ripples building. Hope this front end lasts.

DAB- so far. Better than I thought considering I expected snow to start around midnight.

[Chicago Storm]

Lake enhancement is coming onshore in the immediate downtown area currently.

Snow started here in the last half hour. Dusting on everything. 3° with a dewpoint of 0° so I guess you could say it’s pretty humid out.

Multiple meso-lows out over the over the lake. That southern one is potent.

You think they drift west enough to make it on shore?

IWX already thinking about upgrading us, upped us to 4 to 7

Nice frontogenic band setting up over me. Finally getting better rates and bigger flakes. Curious how rest of night will shape up.

100% pure mountain sparkles lol

I do think that it'll move further onshore.

The main question more-so is how far onshore it'll move and how long it will take up residence in a particular area.

That doesn’t even look real

Still migrating west a bit, has the looks of an Evanston/Wilmette special. But its definitely east of where most hi-res guidance was placing it at this point.

The 00z HRRR and NAMnest initialized adequately with it. Suspiciously low QPF response given the evolution progged, although presumably it would be higher ratio than Kuchera output.

Take it to the bank.

Could this please stay over me for hours. Great flake size and rates now.

Chicago NWS update

With increasing low-level convergence forced by
stronger easterly flow through the night, would have to think
that the lake effect snow band should have more success moving
inland with time, even if just for a few miles. Based on the
current trajectory and west/northwestward drift of the snow
band, areas near and north of Evanston appear most in line to
see the lake effect snow overnight. After daybreak, the
expectation is for the snow band to pivot back southeastward
across northeastern Illinois during the morning hours and into
northwestern Indiana during the afternoon as the low-level wind
field backs along the backside of the departing storm system.

Lake enhancement is doing work downtown.

Looks like about SN 1/2SM on the EarthCam.

Seems quite a bit high for areas away from the lake. I don’t see anyone in DuPage county getting to 4 inches.
