A very nice winter-storm analog page put together by the Cooperative Institute for Precipitation Systems · Saint Louis University provides some food for thought for this upcoming storm. While the models are more or less insisting this storm bypasses us, the analogs, based on the 12z (7 am EST) run of the NAM from Thursday, are certainly interesting.
The mean snowfall for the Top 15 analogs, shown below, certainly is tilted toward a snowy event.
I’ve also included a snapshot of all the top analogs below; the date is at the top. The scale can be found on the preceding “mean snowfall” map.
