Synopsis
A cold front will progress south of the area tonight with high pressure moving overhead on Thursday. A warm front will lift into the area Friday. A pair of cold fronts will cross the area Saturday night and Sunday. High pressure builds to the south of the region early next week.

Near Term - Through Tonight
A cold front will continue to progress south of the area through tonight. Gusty northwest winds and mountain wave stratocumulus exist in its wake, both of which should subside this evening. The downsloping winds combined with the unseasonably mild airmass have resulted in temperatures well into the 50s and 60s across the lower elevations. Some sprinkles/drizzle may be occurring along the Alleghenies in the upslope flow, but continued subsidence will be ending this potential by late afternoon.

Surface high pressure will quickly move overhead tonight in a relatively fast zonal flow pattern aloft. Mostly clear skies and light winds will result in temperatures falling close to the dew points. Most locations will be in the 30s, with the highest chance for subfreezing temperatures in the typical piedmont and mountain valleys. Some patchy fog is possible.

Short Term - Thursday Through Friday Night
The surface high will continue to move eastward Thursday and Thursday night. Dry conditions will prevail, although there will be an increase in mid and high level clouds. Warm advection will commence on the western periphery of the high, allowing high temperatures to rise to the mid to upper 50s in the southwestern half of the CWA. Upper 40s and lower 50s will be found to the northeast. Mild conditions continue Thursday night with lows in the mid 30s to mid 40s. If enough breaks in the clouds occur, some patchy fog may develop again.

A warm front will approach or possibly already be over the area Friday. While this should usher in even milder air, there is some question with how quickly it is able to push through. Overrunning moisture will result in the development of low clouds, and there could be some light rain showers or drizzle at times. Thus there could be a range in temperatures from near 50 to the mid 60s. Southerly winds will also increase, especially along the ridges above a low level inversion. Gusts on the higher peaks could reach 35-45 mph, especially during the morning.

The front could attempt to sag back south into the area Friday night. Other than the potential for slightly lower temperatures (upper 40s vs 50s), the exact position shouldn't matter too much. Forcing and moisture will increase through the night as the next low center lifts into the Tennessee and Ohio Valley. Rain chances will continue to increase, especially the second half of the night.

Long Term - Saturday Through Wednesday
Rain and above normal temperatures can be expected on Saturday as a warm front lifts to the north and a cold front approaches from the west. Precipitation chances peak Saturday morning with beneficial rainfall lingering through the afternoon. High temperatures will be in the mid to upper 60s across the area with higher elevations staying in the mid 50s. There will be a large spread in overnight temperatures as the cold front pushes through the forecast area. Lows will be in the 40s for those along and east of the Blue Ridge with those west ranging from low 20s to 30s. Conditions dry out overnight as winds increase.

In the wake of the cold front, gusty winds and cooler temperatures are expected on Sunday. West winds gust 20 to 30 knots during the day with locally higher gusts expected at higher elevation. High temperatures will be in the mid 40s to low 50s for most with the Alleghenies staying in the 30s. Overnight low temperatures will be in the 20s for most with lingering upslope snow showers possible.

Conditions dry out Monday and Tuesday as surface high pressure builds over the region. Temperatures gradually warm each day with highs in the 40s to low 50s for most by Tuesday.

Marine
In the wake of a cold front, northwest winds are gusting around 20-25 knots over the northern half of the Chesapeake and upper tidal Potomac River. Small Craft Advisories are in effect for these portions of the waters until 5 PM.

Sub-SCA (Small Craft Advisory) conditions are expected tonight through Thursday night as high pressure builds across the area. As the high moves offshore Friday, south winds return. SCA (Small Craft Advisory) conditions will be possible at times Friday afternoon and evening, especially where the warm front is able to lift to the north.

Southerly winds on Saturday shift to northwesterly overnight as a cold front moves across the waters. Small Craft Advisory criteria winds are likely both Saturday and Sunday.
