... A weak cold front drifts south across the area tonight with benign conditions expected through early next week. Warmer mid week.
NEAR TERM /THROUGH SATURDAY/... As of 1245 PM Friday...
The main weather producer across the entire country during the period will be focused in on a surface low pressure system hugging the eastern seaboard. Beyond mid to high level clouds occasionally streaming through the area and slightly gustier winds in our northeast West Virginia mountains on Sunday, no additional impacts are expected for our forecast region in terms of this coastal system. For us, the only thing of note will be a weak backdoor cold front drifting south into the Central Appalachia overnight tonight. Moisture associated with the boundary is lackluster at best, so am only anticipating a low stratocumulus deck to ooze into our northern territories late tonight, then continue southward before scattering out and clearing by Sunday afternoon.
Afternoon temperatures both today and Saturday will rise into the mid to upper 40s, still falling short of the climatological norm for this time of year. Mostly clear skies overnight will yield sufficient radiation cooling, dropping Saturday morning lows down into the 20s area wide.
SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/... As of 205 PM Friday...
Dry regime in place. Upper level low over the southeast coast departs for Atlantic Canada with weak high pressure influences stretching down through the northeast US. Also get brief ridging aloft in the short term, but the sensible weather translation is slightly below normal temperatures with increasing cloud cover through Sunday night.
LONG TERM /MONDAY THROUGH FRIDAY/... As of 205 PM Friday...
Weak low pressure moves in with a weak upper trough, but will not be able to get much in the way of layer moisture for the weak omega to utilize and produce precipitation. Therefore, only low end POPs over the northeastern quarter of the CWA through Monday night. High pressure returns, the upper trough exits, and broad scale ridging keeps the area dry and a bit warmer through mid week. A strong low pressure system develops over the plains and a cold front charges through the Ohio Valley with the next potential for meaningful precipitation across the CWA. Expect another sharp temperature drop behind the front for Friday and a much colder set up for the following weekend.
