Friday 1-21-11 update:
Thankfully just a heavy dusting last night, at least where I am at the end of Staymon...less than a half-inch, but driveway was solid white. Our NEXT system (no, it doesn't seem to end, does it?) is coming in Monday and will hang around intermittently (NW snow showers) through Wednesday. This could be a big issue for travel in the Foothills and Piedmont should a classic cold wedge develop along the eastern flanks of the Blue Ridge. Freezing rain or a wintry mix may set up shop there.
Most of our forecast precip is snow, but the temps are not crashingly cold, like we're having today. Rain could mix in on Tuesday, which is never a welcome situation when re-freeze comes in once it gets dark.
For ACA, the NAM can't see the system yet as it's just a frog hair out of sight for the 84-hour model run. The GFS 120-hour outlook, 5 days, continues to see a 2-4" storm total....except for the overnight 1am run today where it jumped ACA significantly into the 8-10" range.
Discomforting, but one model run does not hysteria make, unless it keeps it up. Not thrilled over the prospects, though my new set of chains came in, which makes me feel a lot better~! I'll update again Saturday sometime.
