... High pressure will build in from the west through Saturday. Low pressure will move from the mid-Mississippi valley Saturday to the southern Mid-Atlantic Saturday night. High pressure will follow for the beginning of next week.
NEAR TERM /UNTIL 6 PM THIS EVENING/... Low pressure will continue to move north and east of the Canadian Maritimes while high pressure builds over the Great Lakes. A blustery northwest flow will continue to usher in chilly conditions for this time of year. Max temps will range from the 30s in the mountains, to the 40s across most other locations, to near 50 in central Virginia.
An upper-level disturbance will pass through the area this afternoon in the northwest flow aloft. Colder air aloft will allow for limited instability underneath the subsidence inversion. However, the airmass is very dry. Did allow for an isolated sprinkle or flurry across northern Maryland into the Shenandoah Valley of Virginia, eastern West Virginia and central Virginia...but most of the time will turn out dry.
SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/... High pressure will remain in control tonight allowing for clear skies and light winds. Temperatures will be about 10 degrees below average.
Low pressure will be diving across the center of the region Saturday and Saturday night. Clouds will increase during the day. The NAM, European and GFS models are all indicating that precipitation, mainly in the form of snow, should stay well southwest of the Metro areas. Confidence that the northern edge of snow pushes into Northern and Northeast Virginia. No advisories, watches or warnings at this time due to this low confidence.
Once the low pressure pushes into the central and eastern Carolinas, chilly high pressure will nose southward and provide reinforcing chilly air in behind the low pressure system. The below average temperatures will continue Sunday and Sunday night.
LONG TERM /MONDAY THROUGH THURSDAY/... Strong high pressure for this late in the season will dominate the entire northeast and mid-atlantic through the first half of next week keeping temps cooler than normal. A slow frontal zone will approach the area from the west late in the week bringing the next chance of rain to the area. Due to the strong ridging to the north and east of the area, the timing of this frontal zone could be potentially delayed. Ensemble spaghetti plot showing a lot of uncertainty with the timing of this front into the area. Temperatures will start trending upward during the second half of next week as high pressure begins to weaken and winds turn more southerly or southwesterly.
