Is the low snow total up the valley because of sleet or cold rain?

Downsloping most likely off the Apps.  I think those lower totals have probably been there all along, but that lollipop near Knoxville was hiding it.  Ask @tnweathernuthow much he likes downsloping.....LOL.  .It is probably the one set-up where I can out score him in JC.

RGEM out to 84

Man, that looks tasty. Something like that looks like it could nail the whole state pretty well, including Chattanooga. 

I am nervous about that second wave approach that 18z GFS advertised for the East. Would much rather get involved in the initial wave (like the RGEM shows) and go from there.

The lower Snow Totals in the Valley are quite possibly due to the average difference in occurences ingested into the Model's. I.e,. say, Kingsport got 1 inch the last 3 Snowfalls while Knoxville got 2 , the Models over time will show Knoxville getting more in their output.  Of course, if any wind is forecast, downsloping will be as well. The City to City Avgs may well be factored in now . That I don't know.
