Despite the outlier NW 12Z GFS track; main snows still stay SE from Central IL over to DTW. As Euro seems fairly locked in will go 1.5" far NW, 2-3" downtown and southside, 5" Kankakee
fairly sharp cut-offs on the northwest side of
the precip shield are common in these synoptic set-ups even with
stronger surface lows.
NW LOT shaft advisory in effect Wed-Fri next week.
