000 FXUS61 KAKQ 252339 AFDAKQ Area Forecast Discussion National Weather Service Wakefield VA 739 PM EDT Thu May 25 2017 .SYNOPSIS... Unsettled conditions will continue through this evening as an upper level trough crosses the local area from the west. Conditions improve on Friday. Warmer temperatures and chance for showers and thunderstorms will return over the weekend. A cold front will approach from the west on Memorial Day. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... Dry slot continuing to fill up w/ BKN CU and developing (SCT) tstms as an upper level trough enters the region...steepening lapse rates. FA remains under marginal risk svr from SPC...main threats from any stms will be gusty winds/hail. Otherwise...VRB clouds/partly sunny into this evening. For the overnight...becoming partly cloudy S w/ any lingering SHRAS waning...mostly cloudy N w/ possible additional ISOLD-SCT SHRAS. Lows from the m50s W to l60s at the immediate coast. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/... Other than possible ISOLD SHRAs and VRB clouds far NNE locations early Fri as upper level low is slow to reach New England...drying out w/ deep layered WNW flow. Expecting a return of temperatures back to or above normal w/ partly-mostly sunny conditions. Highs mainly 80 to 85F...except u70s at (most of) the beaches. Weak ridge aloft nudges into the region from the WSW Fri night into Sat. Models in a bit better consensus w/ the arrival of weak S/W tracking into the FA by Sat afternoon. Combination of daytime heating and that S/W in WNW flow aloft will likely result in at least SCT convective development. Will have PoPs increasing to 30-50% over most of the FA. SPC has outlooked wrn/central areas of FA SLGT risk svr...other areas marginal svr. Otherwise...partly cloudy Fri night- Sat morning...then becoming mostly cloudy Sat afternoon. Lows from the u50s NW to the low 60s SE. Highs Sat from the m-u70s- around 80F on the eastern shore to the m-u80s inland. Nearly zonal flow aloft remains Sat night into Sun. Another S/W aloft expected to arrive during Sun...which again combined w/ daytime heating likely results in SCT convective development. Lows Sat night ranging through the 60s. Partly sunny Sun w/ highs mainly in the l-m80s (70s at the beaches). Will highlight possible strong to severe tstms in HWO for the weekend. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... The somewhat unsettled weather will continue into Monday with the baroclinic zone nearby and a strong upper jet just north of the area. Expect additional showers and thunderstorms once again on Monday in the cyclonic flow. It will be a warm day with highs in the mid-upper 80s. The front will stall out over North Carolina on Tuesday and may allow for additional showers and storms Tuesday across NE NC and south VA. High pressure builds across the region for Tue Night-Thursday with dry and seasonable conditions expected. && .AVIATION /00Z FRIDAY THROUGH TUESDAY/...

Widespread showers and thunderstorms have mostly ended over the CWA except for the Eastern Shore where it should end before midnight. A few scattered showers still linger over portions of Central Va and NC but should be ended in another hour or so. Winds are mostly SE-SW 10-15 kt and gusty. The winds will diminish inland but will likely be 10-20 kt near the coastal areas. VFR conditions will take hold tonight as drier weather moves into the region. Friday should be dry with VFR conditions, then sct showers and storms return for Saturday into early next week as the pattern remains somewhat unsettled.

&& .MARINE... Latest sfc analysis shows a broad area of low pres across the Mid Atlc - OH Valley with its main cold front already pushing offshore. SW flow continues tonight behind the front, and still looks to be enough of a gradient for 15-20 kt winds over most headlines over the Bay/Sound/Lwr James extend through at least Fri morning. The SCA over the ocean is for seas up to 5 ft out 20 nm. Weak high pres then builds in for late Fri/Fri night leading to improving marine conditions. Sub-sca conditions expected to continue into the weekend. && .TIDES/COASTAL FLOODING... Previous onshore flow combined with high astro tides will result in elevated water levels through Friday. Have issued several coastal flood products to account for this. See CFWAKQ for more details. && .AKQ WATCHES/WARNINGS/ADVISORIES...
