... High pressure will build overhead through tonight. Low pressure will develop along the North Carolina coast Friday and move out to sea Friday night. High pressure will return for Saturday before weak low pressure impacts the area early next week.
NEAR TERM /THROUGH TONIGHT/... Cold front has crossed the region with blustery northwest flow occurring this afternoon area-wide. Strato-cumulus has been gradually scattering out and diminishing, and this trend should continue for the rest of the afternoon. At the same time, high clouds will once again be increasing late in the day and overnight in response to a developing jet max and next fast- approaching system. Temperatures should still be able to fall quite a bit overnight with lows in the teens and 20s.
SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/... Northern stream upper level trough will be quickly approaching the region during the morning Friday. At the same time, additional shortwave energy will be rapidly pushing eastward from the lower Mississippi River Valley and across the Appalachians by the afternoon. These two shortwaves are expected to remain un-phased until well offshore, which will keep any precipitation on the low side. That being said, surface low pressure is expected to develop along the baroclinic zone left by today's frontal passage near the North Carolina coastline Friday morning and move northeastward and offshore Friday afternoon. This now looks like it will be just close enough, when combined with the forcing from the northern stream trough and intensifying jet max to bring some light snow to portions of the region on Friday. Model differences still exist with respect to westward extent, but the trends today have been for high chances for our region.
Have increased snow probabilities to likely across portions of southern Maryland and to chance as far west as the I-95 corridor for late Friday morning, peaking in the afternoon, and ending during the early evening. Have shown accumulations of less than one inch for the Maryland counties that border the Chesapeake Bay, going to a trace or less west of I-95. However, uncertainty is still quite high at this time. Highs during the daytime remain on the cold side, in the 30s area-wide.
Flow will turn northwest following the system's departure Friday night, with a brief period of upslope snow showers likely along the Allegheny Front. Accumulations will be low though as moisture will be quite shallow, up to about an inch of snow or so. Lows Friday night in the 20s.
High pressure will then build in south of the region on Saturday, with dry conditions expected. Highs Saturday in the upper 30s to mid 40s and lows Saturday night in the 20s.
LONG TERM /SATURDAY THROUGH THURSDAY/... High pressure, centered to our south on Sunday, will generate southerly flow over our region, allowing for high temperatures to reach the mid to upper 40s for most of our CWA. A shortwave trough will move across the area Sunday night into early Monday. This will increase PoPs over our area, but still uncertain how much QPF will be associated with it and any p-types.
Guidance suggests that mid to upper level energy could bring a slight chance of precipitation between Monday and Tuesday with still above normal temperatures -reaching the 50s. A front could bring a chance of precipitation Tuesday night into early Wednesday. High pressure builds behind this front Wednesday into Thursday bringing dry and more near-normal high temperatures.
