Sweet Spot of the NAM Runs

Final Update for this post...
While I do not fully endorse these last runs of the NAM, that is yesterday's 0z run and today's 12z run, the idea of overachieving is out there. A consistent signal of 1-3" with possible 4" amounts, generally along and north of I-64. Of course, the uplands and mountainous terrain of eastern Kentucky could also see similar totals, but areas generally south of the Parkway will see less accumulation.

Last night's run of the NAM is the first of two runs that should give us a good indication of amounts of snowfall for the region. While individual locations may vary, I did notice that the heavier amounts have shifted north from earlier runs.

Amounts of 1.5 - 2.5" could be realized for Louisville and Lexington. That is higher than the 1" or less I was forecasting for our region. In fact, areas south of Louisville may get an inch or less instead...almost a mirror image of my previous thinking.

Hopefully, virga will not eat away at whatever precious snow that falls. That is always a bummer.
