... High pressure will cover the area through Thursday, with below normal temperatures through at least Wednesday. A low pressure system over the central United States arrives by Friday and will result in widespread rain for our area. The chance of precipitation continues into the beginning on next week.
NEAR TERM /THROUGH TONIGHT/... As of 107 AM EST Wednesday...
- Cold and dry today and tonight.
High pressure in the Ohio Valley this morning will slide east today into tonight. After a very cold start this morning, temperatures will climb to highs in the lower 30s in the northern mountains to the mid 40s in the Piedmont. Dry weather continues tonight into Thursday. Under mostly clear condition tonight, low temperatures will drop into the teens and lower 20s.
High confidence in the Near Term Forecast.
SHORT TERM /THURSDAY THROUGH SATURDAY NIGHT/... As of 155 AM EST Wednesday...
Confidence is high for dry weather on Thursday, but light rain will arrive on Friday with clouds lingering into the weekend.
High pressure should exit offshore on Thursday but allow the Mid Atlantic to remain dry. A low pressure system should organize across the southern Mississippi River Valley during Thursday night and track northeastward toward the Appalachian Mountains by Friday. The models have slowed down the arrival of the moisture associated with this system, so rain chances have been eliminated for Thursday night and focused more on Friday. A breezy southerly wind should accompany the rain. Most of the dynamical lift will pass to the northwest across the Ohio River Valley, so any rain amounts should remain light with under a quarter of an inch expected.
Another wave of low pressure should develop across the Gulf Coast during Friday night into Saturday, which will keep considerable cloudiness across the Mid Atlantic to start the upcoming weekend. Moisture from this wave of low pressure may arrive during Saturday afternoon into Saturday night with rain chances maximized over North Carolina and parts of the Virginia Piedmont. Despite the cloud cover, the aforementioned southerly wind will provide warm air advection that should push temperatures higher each day. Saturday may see high temperatures reach the 50s and 60s, while low temperatures should stay elevated in the 40s by Saturday night.
LONG TERM /SUNDAY THROUGH TUESDAY/... As of 155 AM EST Wednesday...
Confidence is moderate for chances of rain during early next week with colder air entering the Mid Atlantic by Tuesday.
An upper level trough should approach the Ohio River Valley on Sunday, while moisture from a wave of low pressure exits the East Coast. The chance of rain should lessen during late Sunday and Sunday night across the Mid Atlantic. However, once the upper level trough approaches the Appalachian Mountains on Monday, the wind should shift towards the west and become gusty. Light rain showers will arrive along and west of the Blue Ridge, but the downslope flow across the Piedmont suggests that the moisture may struggle to traverse further eastward.
Conditions should turn colder during Monday night into Tuesday as the upper level trough settles across the eastern United States. Rain showers may linger through Monday night but slowly fade by Tuesday morning. As temperatures drop on Monday night, some of the rain could transition to snow flurries across the higher elevations of western Greenbrier County. More rain showers appear possible by Tuesday afternoon as a stronger shortwave trough approaches the Appalachian Mountains, and there may be more areas west of the Blue Ridge seeing snow flurries after sunset on Tuesday.
