Jan 6-8 SE Clipper/Upslope Obs

I'm starting a new obs thread for this clipper threat that has already started here in Northeast TN/Southwest VA and in the NC/TN border counties. This is only just the start and I think areas in the higher elevations (hillbilly weather) could see up to 6-10 inches by Saturday. This is been progged to occur for several days now but no thread has really been made as the bigger interest is for early next week.

Both the NAM and the GFS show a band of enhanced precip forming tomorrow morning-afternoon over the Cumberland Plateau and Northeast TN (Knoxville to the Tri Cities) and into the mountains.

For you folks in North Carolina if enough moisture makes it across the mountains you could see a couple of inches. It would be a nice surprise as I'm sure many are not expecting it. Both models show some nice enhancement of precip associated with the low pressure system as it crosses NC and off the coast.

Then upslope should continue Friday Night/Saturday for the higher elevations.

Dec. 4-5 SE Rain/Snow Storm

I figured since there wasn't a thread for the clipper coming through this weekend that I'd make one. This looks to be a light snow event for folks in Tennessee and the Mountains, but it will probably start out as rain in most of the lower elevations.

Been taking some quick glances at the GFS and the NAM and there are some pronounced differences between the two models and here is a comparsion from the 18z NAM and GFS:

18z NAM:





18z GFS:





The GFS has a colder solution but there isn't as much precip and the NAM shows a strong clipper system with alot of precip, but it draws more warm air into it. Either way it should start as rain in the lower elevations and then change to snow and the mountains would probably stay snow the entire event.

This is just for the clipper coming through during the weekend and not for the potential southern stream system after that.
