The Pumpkin Pie Event of 12/1/ 2025

[Baum]

Let’s keep it rolling. Why not.
Per Lot:

EXPECTATIONS ARE THAT TOP-DOWN SATURATION WILL RESULT IN A   PERIOD OF LIGHT SNOW SPREADING WEST TO EAST OVER THE ENTIRE   AREA, REACHING THE I-39 CORRIDOR BY MID-AFTERNOON AND THE   CHICAGO METRO AND NORTHWEST INDIANA BY LATE AFTERNOON. MOST   GUIDANCE HAS BEEN CONSISTENT IN GENERATING QPF GENERALLY IN THE   0.15-0.20 INCH RANGE, WITH HIGHER AMOUNTS OF AT LEAST 0.25 INCH   IN THE BROADER ENSEMBLE ENVELOPE SOUTH OF I-80. MEANWHILE, A 3KM   DEEP DGZ INTERSECTING WITH MOST OF THE MID-LEVEL ASCENT WOULD   SUPPORT A HIGHER RATIO SNOWFALL ON THE ORDER OF 15:1 TO EVEN   20:1. PUTTING THIS TOGETHER, A WIDESPREAD FLUFFY SNOW EVENT OF   1-3" NORTH OF I-80 AND 2-4" SOUTH OF I-80 APPEARS LIKELY. HAVE   SOME CONCERNS THAT THE 600 HPA F-GEN NOTED ABOVE WILL FOCUS A   NARROW (COUNTY-WIDE) WSW TO ENE ORIENTED BAND OF HIGHER QPF AND   HIGHER SLR (>20:1) SOUTHEAST OF I-55 IN THE EVENING. IN THIS   CASE, IT IS FEASIBLE THAT A NARROW 4-6" BAND OF SNOW WILL BE   REALIZED. FINALLY, WHILE NOT EXPECTED (10% CHANCE), SYNOPTIC   ENHANCEMENT OF A DEVELOPING MESO-LOW OVER SOUTHERN LAKE MICHIGAN   TONIGHT COULD BACK CLOSE TO THE ILLINOIS SHORE AS THE LOW-LEVEL   SYNOPTIC FLOW TURNS SSE EARLY MONDAY EVENING. WILL THEREFORE   NEED TO MONITOR FOR LOCALLY HIGHER SNOWFALL TOTALS ALONG THE   IMMEDIATE SHORE FROM DOWNTOWN CHICAGO TO THE IL/WI LINE.

Looks like a solid 2-4” out this way.
