NAM vs the Euro cage match storm, Feb 20 - 21

And just like that, it switches over to mostly snow.  Coming down at a pretty good rate with large flakes.  I guess that boundary mentioned earlier brings in some colder air aloft.

The line of enhancement has sagged to just north of Dayton to Farragut/Lenoir City line...PWS behind/north have showed a 4-5 degree temp drop in last hour or so.

Is this the trough?

Crossville reported heavy snow with 1/4th mile vis with the band that just moved through there, explains your situation Shocker!

 Enhanced area is about to move over me it looks like. 

Odd ob to me is rain and 34 in Middlesboro, Kentucky. Surprised they got any rain from this. I never saw anything but pure snow from the first flake. Not even drizzle or a sleet pellet. Just a few flurries and then goosefeathers.

Same all snow here. Our truck driver is driving back from Cincy right now though and said in Williamsburg it was doing nothing at all. So I warned him to be careful going down 75 through Jellico/LaFollette etc because of snow on the interstate. Looks like he will be having a slow go the rest of his trip.

Been ripping fatties for the past 10mins off of Lovell road & Dutchtown. Grass is starting to turn white.

Looping RadarScope in Nashville it seems the flow has turned more NNE than east like it was earlier. The back edge line has slowed way down or even stalled its east progression

The rates and flake size are very impressive when any enhancement rolls through. It looks like it's leaving West Tennessee, I assume in a few hours the transfer off the coast will take place and this will shut off pretty fast.

Appears the leading edge of more backed (northerly) winds shows up on radar. Reflectivty is on a previous page. Here's Correlation Coefficient CC out of Hytop. I've highlighted the same feature.

Changeover aloft is noted well south of Chattanooga. Believe that's where the warm air about 800mb dynamically cooled. Surface changeover is highlighted again. Snow in Florence AL, up on Signal Mountain TN, and now dropping down south of Knoxville. Behind that line the CC is even more solid pink (more correlated all snow). 

Athens and Sweetwater may be the end of the south-ward march along I-75. Points south toward Chattanooga are at a lower elevation. Southeast Tenn will require a miracle (as usual). North winds must work hard to advect low-level cold; dew is too high. Requires heavy precip at the same time. LOL KCHA up a degree as I type.

Snow has slacked up for the last hour as the band moved south into Kingsport. Snow is half melted now. I think MRX does have a point about sun angle this time of February. Of course rates will always overcome sun angle if the snow is heavy enough.

Temp is up to 33.

Big, fat flakes have stopped now off Lovell Rd and it is a lighter snow coming down. Grass, trees, & cars are white. Nothing on the roads or sidewalks here.
