I made it to hky last night for the wknd. like 6z runs a lot for imby. Pretty classic setup aloft for this area like I mentioned earlier in the week, so this shift was not surprising. Biggest hurdle will be boundary ayyer temps from 10am to about 5pm. Then I think most of what falls will lay. Mtns and n foothills will ne crushed.

Well, despite the models last night, NWS is saying nada for Raleigh basically. 

Yeah, unfortunately these models have kept the cold air to the west, but what else is new? It was always a long shot, but I just hope to see flakes in the air with no rain at some point in the next 36 hours purely for the visual!

I wasn’t holding much hope either. I just wanted to see something fall. They've made it feel hopeless. At least if we don’t  get flakes, I wish it wasn’t too rainy.  This killed yardwork for the weekend.

IMO the rain snow line on radar is progressing faster southeast in GA, AL, MS, LA, and TX. The whole gulf coast of TX is in SN and that's not something I would have expected based on previous forecast. It seems as heavier precip moves in, those areas are having no issues changing over to SN. Hopefully the RN/SN line continues this same progression as the precip and sunrise occur in SC and NC.

Burrel, you seeing any snow yet? Do you think the upper level temps get right by this afternoon for most in the upstate or just mtns of the upstate 

Upper level temps are fine for us for the duration of the event,(north if i-85). It all comes down to the boundary layer and how much we cool off at the surface

I'm already ahead of last years storm, it started raining at 49, took forever to get to 35 and snow, while TR already had 5"! Moisture won't be in short supply, that's for sure!

Kinda curious... why do you guys think mby in Danville,  VA are under a WWA instead of a WSW?

Because we are most likely going to waste moisture on rain or mix most of today... I think its a good call. HRRR gives us an inch after a lot of rain.. GFS has us on Eastern edge with heaviest snow in mtns which will surely happen

First time poster, but I've been lurking for a while. It looks like city of Atlanta is right on the edge of the snow/rain line. What do you think the chances are that we get a significant snow event vs. a lot of liquid?

An inch in CoA would mean you did pretty well. Pretty low chance of getting more than that.

I'm heading to gainesville in a little bit but the latest nam is unbelievably close to all snow even here...at least it suggests a sloppy mix of rain/sleet/snow..or even all snow if it's heavy enough...much of the day.  Never ceases to amaze me how often it comes down to not just one degree here every time. Probably a good sign for much of NE Ga/upstate if i'm this close way down here. 

valid at 18z this afternoon
