Interestingly, the 12z EPS mean is coming in a bit higher for Chicago than the 6z run.

This run also puts O'Hare down to -1°F Monday morning with a snow depth of 6 inches.

12z vs 6z below

12z Euro seems to have caught on with the WAA, so totals may not be as high as previous run, especially south of Chicago. Waiting on a few more frames.

A slight bump upwards in totals, too.

Canadian was cold, Euro running now.

% for >3" is lower than the 6z run for Chicago.

With snowcover, Euro puts O'Hare at -1°F next Monday morning.

00z Euro held course for Chicago.

Big change on the 00z GFS for Chicagoland Thanksgiving weekend, something to watch. 18Z run posted below.

That last band was really nice, winding down now and the sky is clearing as I look to my northwest.

I can confirm as well, a couple rounds of it while I was walking outside. The wind has really picked up, too!

Mesoscale Discussion 2202 NWS Storm Prediction Center Norman OK 0955 PM CST Sun Nov 09 2025 Areas affected...Northwestern Indiana and northeastern Illinois Concerning...Heavy snow Valid 100355Z - 100900Z SUMMARY...An intense lake effect snow band will drift slowly south-southwestward across northwestern Indiana and northeastern Illinois through the early morning hours. Heavy snowfall rates of 2+ inches/hour are expected under the core of the band. DISCUSSION...Regional radar data shows a well-defined snowband favorably oriented along the long axis of Lake MI. This snowband is on the backside of a mesoscale low that evolved off of Lake MI and is moving slowly southward across far northern IN. As this feature continues southward, and low-level flow continues veering to a north-northeast direction over Lake MI, the band will have a tendency to drift gradually south-southwestward across far northwestern IN and northeastern IL through the early morning hours. The 00Z GRB sounding sampled very cold temperatures aloft (-40C at 500 mb), which is yielding steep low/midlevel lapse rates and a deep convective boundary layer (aided by relatively warm lake waters). Given the favorable/persistent orientation of low-level flow down Lake MI and significant convective enhancement, heavy snowfall rates of 2-3 inches per hour are expected under the core of the band as it continues south-southwestward. Isolated lightning flashes will also be possible. There will likely be a sharp drop-off in the heaviest snowfall rates as the band tracks southwestward across northeastern IL (owing to less favorable thermodynamic conditions), though exactly where this will occur is uncertain. Additionally, gusty winds within the band will yield significant visibility reductions where snowfall rates are maximized. ..Weinman.. 11/10/2025 ...Please see www.spc.noaa.gov for graphic product...

I'm in River North. I moved to Chicago back in the spring and never thought I'd see LES of this magnitude. Looking forward to experiencing this.
