I’ve been pretty much think 1-3” for the CWA along and north of I-80. However, I fully agree that there is much more upside potential. If thermals work out as the GFS/RAP and others show, definitely could see an axis of 3-6”+ into the CWA. .
With colder air not filtering in until right before things are getting going, there isn’t going to be sufficient time for the already mild surfaces/ground to catch up. Add in that’s it’s noting going to get colder than the upper 20’s most likely either. Maybeee elevated surfaces towards the end, but that’s a stretch depending on how long precip actually lasts.
The HRRR has done very well since we flipped to the milder pattern. Has hit on just about every warmer day thus far around here. So I’d say ride it... .
Down to 4” snow depth at RFD and 5” at ORD, with outlying areas across N IL still in the 6-9” range. That should all vanish the next two days, with temps into the 50’s, and also DP’s into the 40’s today and even the 50’s for a time tomorrow. .
With no additional snowfall accumulation expected in the final days of the month, February 2021 will finish as the 9th snowiest February on record for Chicago...
