SYNOPSIS... A drying trend will continue for several days as high pressure eases into the area. A reinforcing cold front will arrive tonight and early Thursday, bringing the coldest airmass so far this season into the area. High and low temperatures well below normal will persist Thursday night through Saturday before a moderating trend commences early next week when the next cold front arrives.
NEAR TERM /THROUGH TONIGHT/... As of 945 AM EST Wednesday: Visible satellite imagery and observations have shown the gradual improvement and dissipation of the dense fog across the Piedmont and foothills of the Carolinas and northeast Georgia. Only two locations remain with a visibility less than 1/4 mile, so the ending of the Dense Fog Advisory looks to be right on schedule at 15Z. Temp/dewpt trends look good, so the only items for the morning update will be to drop the Advisory and to make some alterations to the sky cover to account for fog that has temporarily lifted to a low cloud deck over the Piedmont. Otherwise, the afternoon should be fair.
Meanwhile, the next weather-maker in the form of a strong upper low will be sliding east across the U.S./Canada border, with a very strong and very cold Arctic high diving into the High Plains late today. The front ahead of the high isn`t really all that wet and with each run they`ve trended drier. WPC doesn`t even bring any QPF into the forecast area anymore, but for the sake of consistency did blend in a little from the previous run (what`s 0.01" among friends?). What little moisture there is associated with the front will all get squeezed out over the mountains (though the rest of us could see an increase in clouds overnight tonight). It`ll be cold enough that the higher elevations will likely see some snow showers or at least flurries, but again just not enough moisture for any accumulations.
SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/... As of 200 AM EST Wednesday...A broad upper trough will drift east across the Ohio Valley to the Mid-Atlantic coast Thursday thru Friday. This trough will bring a strong, but rather dry, cold front thru the region on Thursday. Strong 850 mb CAA will ramp up across the NC mountains during the day, resulting in gusty winds and falling temps. The piedmont will see temps near normal, while the mountains will be about 10 degrees below normal Thursday. The gusty winds will linger thru the overnight in the high terrain, but become fairly light in the piedmont. Temps will fall into the teens in the mountains and 20s piedmont. The combination of wind and temps will result in wind chills in the 0 to -10 F range toward daybreak Friday. Wind chill advisory is -5, and generally only elevations above 5000 ft look to get that cold.
On Friday...a modified arctic air mass will build in from the NW. Winds will gradually subside in the mountains, but it will still feel brisk, with temps at least 10-15 degrees below normal, despite sunny skies. The center of the high settles over the central Appalachians by 12z Saturday. Lighter winds will keep wind chills above advisory criteria, but overall, it will be a chilly night. Lows in the teens to mid 20s.
LONG TERM /SATURDAY THROUGH TUESDAY/... As of 130 AM EST Wednesday: The very cold airmass in place Saturday under surface high pressure centered over our region will move east and offshore from the mid Atlantic on Sunday. This will bring a change in wind to a more southerly direction resulting in a significant warming trend to around normal to start the week. The upper pattern will be nearly zonal from this weekend to mid week across our nation with an average slight trough east of the Rockies. The next shortwave will cross the Plains Sunday with some increased in moisture coming out of the Gulf across the SE. Expect some upslope showers ahead of this system to occur late Sunday and Sunday night from near Clayton GA to Tryon NC. The southerly 925mb wind of 15 to 30kts will shift to SW early Monday ending the upslope affect as it will be more parallel to the ridge lines. Both the GFS and ECMWF thins out or slightly dries out the approaching frontal precip band Sunday night into Monday. The GFS dries it out a bit more. Either way there will be scattered showers over the whole area but more initially over the NC mountains. There may be some very brief upslope precip along the TN and NC border north of AVL late Monday but that is mostly shown on the EC which may be the lower confidence model. The newest GFS dries our area out rapidly late Monday with no upslope in Mtns. High pressure builds in briefly on Tuesday then a mostly dry cold front is nearing from the NW late Tuesday night. Increase in clouds as a result.
Temperatures of 10 to 15 degrees below normal Saturday will modify to near normal for Max Temps Monday and Tuesday.
