... Low pressure will drift over the area this weekend. High pressure will briefly return early next week, then a cold front will approach from the north during the middle of the week.
NEAR TERM /THROUGH TODAY/... Main round of convection has pushed off to the east. However, the parent low pressure system is still spiraling over southern West Virginia, moving slowly northward. Conditions remain conditionally unstable across the area, with the best CAPE values rooted near the boundary layer over lower southern MD and adjacent coastal waters. As such, new convection has developed over eastern NC and southeast VA, and is pushing north. Most of the area will probably be limited to scattered showers through daybreak, but a few thunderstorms are possible over southern MD.
Mid/upper dry slot pivots across today, with much of the area expected to remain dry and seasonable (highs in the upper 60s to lower 70s). As the upper trough axis slowly pivots toward the region by this evening, scattered showers will likely develop in the I-81 corridor and gradually push eastward.
SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/... Surface low pressure will lift northeastward as upper low slowly moves overhead. Low 1000-500 mb thicknesses and 850 hPa temps dropping to near 0 C are quite low for this time of year, and are indicative of instability under the upper low. Scattered showers seem likely Sunday as a result, and can't rule out a little graupel either given the low freezing levels.
The upper low will finally push eastward offshore early next week as high pressure builds from the Ohio Valley to just south of the Mid-Atlantic. This should result in dry weather and warming temperatures, although a few showers are still possible Monday mainly east of I-95.
LONG TERM /TUESDAY THROUGH FRIDAY/... High pressure over the southeastern United States will be in control of the weather on Tuesday as a weak low pressure system moves eastward through the Great Lakes, its attendant cold front moving into the Ohio Valley. This will lead to dry and warm conditions with highs likely reaching the upper 70s to low 80s.
The low will then pass eastward across the northeastern US on Wednesday, with the cold front moving near the region. Thus some showers/thunderstorms become possible on Wednesday. It should still be quite warm with highs once again in the upper 70s to low 80s.
The front will then likely stall out near the region on Thursday before a disturbance moves along it on Friday. This will keep chances for showers/thunderstorms in the forecast through the end of the week. Temperatures will be dependent on the frontal boundary location, but will show 70s for now.
