Winter Storm THREAT - Hoping For a Westward Shift

Many of the models are advertising a winter storm for parts of the region for the latter part of the weekend. Unfortunately, most of the precipitation will be falling in the form of plain liquid. However, as colder air infiltrates the region, look for a possibility of heavy, wet snow to fall.

I'm still not ready to post totals yet, but this has the signature of a 'whopper' type system. This is the kind of system I've been wanting to see all winter long. Currently, I like the looks of this one but am still cautiously optimistic at best.

I'll be relying on the NAM model at about 36 hours out as I feel that this will be the prime time to begin hashing out totals if this storm continues to shape per expectations.

AT THIS TIME, obviously subject to change, surface temperatures will be above freezing throughout much of the event. East to SE Kentucky stand the best chance for accumulating snow, probably in excess of 4". This would be a wet snow and could cause outages if enough accumulates.

Personally, in a setup like this, I would love to see the storm shift a little bit westward. This would really help produce a good snowfall for many in the region.

Besides the NAM model, here are some additional sites to look at...
