... High pressure will remain across the Mid Atlantic through this weekend. A low pressure system will affect the region early next week.
NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... An elongated area of high pressure stretches from the Deep South northeastward across the southern Appalachians and off the Mid-Atlantic coastline this evening. At the same time, a weak cold front is tracking through the Ohio Valley into Pennsylvania.
The weak front will push east-southeastward tonight, with its tail end crossing the region overnight. Aside from a shift to light northwest winds and a few added cirrus, no real sensible weather impacts are expected with this decaying front. Although as winds do turn to the northwest, there may be some terrain- induced strato-cumulus along the Allegheny Front by morning. Should still have decent radiational cooling tonight, but with some added light winds and higher dewpoints, won't be as ideal as previous nights. Lows in the 40s to near 50F for most, except low/mid 50s in the urban centers and along the shorelines of the Chesapeake and Tidal Potomac.
SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/... High pressure will gradually build back overhead for Friday and Saturday, providing for mostly sunny skies, relatively light winds, and mild temperatures. There may be some patchy fog each late night/morning, but nothing widespread expected. Highs will reach the low to mid 70s, with lows in the 40s/50s.
LONG TERM /SUNDAY THROUGH THURSDAY/... High pressure system will move away from the east coast on Sunday. A cold front approaches from the west with a wave of low pressure tracking northeast from the Gulf states towards the Mid-Atlantic region Monday into Tuesday. This system will put an end to the dry spell we've been experiencing, with precipitation associated with it starting sometime on Monday and remaining into Tuesday.
The pattern will evolve from warm and dry to cold and unsettled as this system moves through, with some uncertainty on the timing. In the upper levels, a large and deep trough will move over the eastern CONUS Wednesday into Thursday. Guidance suggests that this could bring some upslope showers on Wednesday, and then dry into Thursday.
High temperatures on Monday will be between the low to mid 70s decreasing into the 60s into Thursday.
