SYNOPSIS
A backdoor cold front will sink south of the area tonight. The boundary will return north as a warm front Sunday into Monday before secondary cold front approaches and stalls near the area for the middle and latter portions of next week.
NEAR TERM /UNTIL 6 AM SATURDAY MORNING/
High pressure remains centered over the New England Coast this afternoon while an upper-level ridge axis is slowly moving off to our east. An upper-level trough is building over the central CONUS and a backdoor cold front is currently located near the Potomac Highlands into central Virginia.
The backdoor boundary will most likely stall out near the area through late this afternoon before eventually pushing off to our south and west tonight as high pressure strengthens along the New England Coast.
As convergence strengthens along the backdoor boundary into this evening, this will combine with moisture advection (southerly flow aloft around periphery of the high) and instability, triggering some showers and thunderstorms over the Allegheny and Potomac Highlands into the Shenandoah Valley. This activity will likely advect eastward into the metro areas late this evening and overnight. A rumble of thunder is possible overnight as well due to limited elevated instability above the marine layer.
Low clouds and noticeably cooler conditions are expected overnight as the onshore flow continues behind the backdoor cold front. Lows will be in the 50s for most areas, with upper 40s in portions of northern Maryland.
SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/
The backdoor boundary will remain to the south and west through Saturday night while high pressure remains centered near the New England Coast. An onshore flow will continue during this time while warm and moist air overruns the marine layer in response to an upper-level trough pushing into the Midwest. This will result in plenty of clouds along with periods of rainfall and unseasonably cool conditions. There may be some breaks in the rain, but for most of the time near and west of Interstate 95, there will be some rain around. Perhaps there will be some more breaks east of Interstate 95 where the overrunning moisture may not be quite as deep.
The overrunning moisture will deepen Saturday night into Sunday morning as the boundary begins to push north as a warm front, and the low-level flow develops a fetch from the Gulf of Mexico.
Therefore, more rain is expected.
The warm front will move into the area Sunday while a weak upper-level trough axis passes through. More unsettled conditions are expected with showers and perhaps even a couple thunderstorms. Sunday afternoon will turn out a bit warmer and more humid as well, but temps still near and below climo. Highs will range from the 60s north of the boundary in northern MD into the metro areas/eastern WV/northern VA to the 70s south of the boundary. The upper-level trough axis will move off to the east Sunday night while the surface boundary remains nearby.
While a few showers are possible, coverage of precipitation should wane behind the departing trough axis. There may be areas of dense fog overnight with plenty of low-level moisture and light winds.
LONG TERM /MONDAY THROUGH FRIDAY/
The unsettled weather pattern is likely to continue across the region for virtually all of next week. Nearly zonal flow aloft favors numerous passing shortwaves that bring enhancements to the daily afternoon showers and thunderstorms. Even at night, isolated showers/storms are possible given the increased moisture and lingering elevated instability.
At the surface, a stalled frontal boundary is likely to be just north of the area Monday, slide south to around I-70 Monday night, then be pushed back north of the area through mid week. However, any change in the position of the stalled front could result in higher or lower rain chances than currently forecast for some areas. A stronger shortwave trough is forecast to cross the area Wednesday night into Thursday, possibly bringing some heavier rainfall and stronger storms to the area.
Afternoon highs in the upper 70s to low 80s Monday and Tuesday warm to the mid 80s Wednesday and Thursday. Very mild overnight lows in the 60s each night due to increased dew points and cloud cover.
AVIATION /19Z FRIDAY THROUGH WEDNESDAY/
VFR conditions are expected through late this afternoon along with dry conditions. Low clouds will develop due to an onshore flow with MVFR conditions developing most likely between 2 and 5Z and IFR conditions developing overnight. Showers are likely to develop overnight, and a thunderstorm cannot be ruled out between 5 and 9z due to elevated instability.
IFR/subIFR conditions are expected most of the time Saturday through Saturday night along with periods of rain and drizzle.
There may be a few breaks of MVFR conditions Saturday afternoon.
More unsettled conditions are expected Sunday morning with IFR/subIFR cigs/vsbys. Cigs/vsbys should improve some Sunday afternoon, but areas of low clouds and dense fog may cause more subIFR conditions Sunday night. Showers are likely Sunday with perhaps a few thunderstorms. Precipitation coverage should wane Sunday night, but a few showers are possible.
Unsettled weather looks to continue for the start of next week.
Scattered showers and thunderstorms are likely each afternoon, with more isolated activity during the overnight and mostly dry in the morning. A heavy shower/storm moving over a terminal could result in brief sub-VFR conditions. Outside of shower/storm activity, VFR conditions are expected.
MARINE
A pressure surge behind a backdoor cold front will cause easterly winds to gust around 20 to 25 knots into this evening.
A Small Craft Advisory is in effect.
The gradient will subside a bit overnight through Saturday, but an SCA remains in effect over the Bay and lower Tidal Potomac River. It will be marginal though with gusts around 15 to 20 knots. The Small Craft Advisory continues Saturday night for the Bay as well as the middle and lower Tidal Potomac River due to onshore winds ahead of an approaching warm front.
The warm front will move into the area Sunday into Sunday night.
More SCA conditions are possible during this time.
West to southwest winds around 5-10 knots at the start of next week as the unsettled weather pattern continues. Scattered afternoon showers and thunderstorms are likely each afternoon. Any stronger storm could produce wind gusts to 35 knots and lightning strikes. A weak frontal boundary dips south into the northern Chesapeake Bay Monday night, then lifts north of the area Tuesday. Otherwise, winds are forecast to remain below SCA conditions.
TIDES/COASTAL FLOODING
Onshore flow will persist through early next week. This will raise water levels and keep them elevated during this time, causing minor tidal flooding for many locations. Moderate tidal flooding is possible around Annapolis and St. Mary's County with the high tide cycle late Saturday night, and again late Sunday night into Monday morning.
