Noticed radar returns were enhancing in area's. Graupel can definitely make it through that dry Column more than flakes. Maybe we'll get a surprise dusting tonight. 

Also critical to our region usually is having the regions north and northwest with some good snowpack. That hasn't really happened yet but looks like over the next few weeks might finally begin to start building. I have family in the UP of Michigan and they at Christmas had zero snow on the ground which is very very rare for them. Usually by end of December the Superior snowbelt region has a couple feet of snow on the ground already. For Detroit area in lower Michigan it's the second least snowy December ever recorded and among the warmest.

As I sit and type this it is snowing now suddenly at my house, looks like virga is trying to overcome the dry air. Not really snow but graupel.

Jeez. We cleared over 2" with this system. It rained HARD yesterday. Sorry NE guys missed out.

Wound up with 1.25 here. Funny that we had more on the roads than the 8" we received back in the March storm.

The death rattle of this little clipper has been impressive. Just shy of an inch here.

Returns back in eastern AR look impressive, not sure they make all the way to us, if they do would imagine it would be much later tonight like between 7 and 8.

MRX updated their snowfall totals for most of the valley from less than an inch for up to an inch.

Huntsville NWS just upgraded their SPS to a WWA for North Alabama and Southern Middle TN.

Ground already starting to whiten up here. Not used to snow falling on frozen ground. Don't get that very often in my neck of the woods.

Well now it has picked up to light snow with visibility lowering slightly in the distance.

So far nothing at my house which is shown on the radar.

Looks like the snow is starting to reach the ground in the southern part of the valley.

Seeing my first flurries in the great valley. Sign the atmosphere is becoming a bit more moist. Funny it's close to MRX forecast start time of 2PM.

Clouds moving in during the morning should help keep temps likely at best in the upper 20s as the warmest, and frozen ground every flake that falls sticks, my biggest concern is overcoming dry air, and how much virga do we deal with before reaching the ground.

Pretty interesting evolution on the NAM. Don't think I have seen a clipper redevelop in the valley before. Plateau usually kills it for us. 
 

Tomorrow's clipper might be fun. I remember back several years ago a similar scenario with dying clipper expected to only bring flurries. While at work in North Knox at the time I remember coming out of the door not expecting anything and finding 2" of snow. While not a lot of snow it was one of the most impressive busts because MRX had only called for just flurries but also specifically said not enough moisture to accumulate at all. Maybe we'll get lucky. Weak dying systems are very capable of creating surprises.

OMG you can actually see the lake effect snow band from Wheeler Lake in Alabama! Curious how much snow that is
From yesterday

Blackouts lifted....

The closest thing I can remember was the PV anafrontal snow we had in January 2014, when it snowed a solid 1-3in across the area. That front and moisture worked for the valley, unlike this time. It was around 16 degrees or so when it started snowing that morning and dropped steadily for an hour or two. The snow was over around noon and the temp at the house was 10 by then. By 3 in the afternoon, it was around 6 degrees and around 3 when the sun set. After it was all said and done, we bottomed out at -3 at the house. Some places went lower. The thing about this current event coldwise, it seems, is that it was over a bigger area. The direction of the 2014 event if my memory is correct was centered slightly further east, so that the coldest readings were over E TN and KY and SW VA. 

I've lived in the valley of east Tennessee since 1989, I cannot recall a daytime temp peaking at 8 degrees. My weather station has been fluctuating between 6 and 8 degrees all day. The coldest day time temp I can recall since we moved here when I was 10 years old is in the low to mid teens for daytime hours. My forecast high from MRX yesterday was a high of 16, not going to hit that. I suspect tonight may go negative air temp.

All that said my official high for the day is 45, just after midnight. Lol

Winds starting to roar here and switching to WNW. Temp is beginning to drop have fallen a couple degrees in the last 15 minutes as the wind switch direction.

Same here poured off and on a good bit over the last hour here. Gonna be a lot of frozen puddles and icy patches on the roads.

Still active snowfall reports as far west as Memphis. Not really showing on radar out there.

Getting closer snow is at the western escarpment of the plateau.
