... A complex low pressure system will cross the region from the west today. Colder air will spill southward into the region behind the system, with mountain snow showers returning tonight, and scattered snow showers possibly extending east of the mountains early Wednesday. Drier high pressure will briefly return over the area on Thursday, but with another moist low arriving from the west for the weekend.
NEAR TERM /THROUGH WEDNESDAY/... As of 640 AM: A Dense Fog Advisory has been posted throughout the region as dry air aloft moves in atop the saturated boundary layer, with model condensation pressure deficits showing values less than 5 mb this morning through 14Z. Slow improvement is expected through late morning.
Otherwise, conditions should be fairly dry around the region through the early afternoon hours until showers redevelop from the west under the approaching upper trough axis this afternoon and evening. Some embedded thunder, and possibly small hail toward evening, are expected with the afternoon convection as lapse rates steepen aloft.
The closed upper low will move from the central Appalachians tonight to the Delmarva coast through Wednesday. The complicated surface low pressure system will continue to occlude overhead, with steadily cooling temperatures from the high terrain down toward the lower valleys this evening through the overnight. Snow levels will crash quickly across the mountains from the west tonight and then cold air will continue to spill southward west of the low through Wednesday as northwest upslope flow moisture becomes rather robust and winds increase. The Winter Storm Watch was migrated to a Warning for all but Jackson County, and an Advisory tier has been added for the rest of the NC mountains except Transylvania and Henderson for now. Will feature these counties, along with Rabun GA, in the HWO since an advisory could be needed at some point. In addition, moisture breaking containment east of the mountains, along mainly the I-40 corridor but possibly into Charlotte, could produce some snow showers early Wednesday. It appears too early for an Advisory there. Will also wrap advisory level wind gusts into the mountain products.
SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/... As of 350 AM Tuesday: The northwest upslope flow moisture into the southern Appalachians will steadily taper off by daybreak Thursday, but winds in the cold advection will remain quite strong through most of the night and yield some advisory level gusts. Otherwise, deep layer northwest flow will continue through Thursday, with drier surface high pressure briefly setting up through Thursday night. Another slug of moisture will arrive back into the region from the northwest Thursday night through Friday, warranting mainly mountain showers. Temperatures will remain a below climo through the period.
LONG TERM /SATURDAY THROUGH MONDAY/... As of 400 AM Tuesday: A flat upper ridge will persist over the southeast U.S. Saturday through Monday. However, a warm front will reactivate from the western Carolinas to the upper Midwest. In the resulting upglide, northern tier temperatures will be interestingly chilly over the weekend. A rain/snow mix mention will be featured mainly north of I-40 for primarily Saturday, and then just along the Blue Ridge for early Sunday. Cool, wedge-like temperatures will be possible with a fropa on Monday.
