552 FXUS61 KAKQ 080003 AFDAKQ AREA FORECAST DISCUSSION National Weather Service Wakefield VA 803 PM EDT Mon Apr 7 2025 .SYNOPSIS... Widespread rain continues this evening, with a few thunderstorms continuing across far southeast Virginia and northeast North Carolina. The rain gradually ends prior to sunrise Tuesday, with dry but cool temperatures expected. High pressure settles in Tuesday night and Wednesday, with below freezing temperatures likely Tuesday night away from the immediate coast. Seasonable temperatures are expected late in the week, with another chance for showers on Friday. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... As of 800 PM EDT Monday... Key Messages: - SVR Tstm Watch has been cancelled across our forecast area. - There is a Marginal Risk of excessive rainfall into tonight across southern portions of the forecast area. This evening, a frontal boundary is draped along or just south of the VA/NC border. North of the front, temperatures have fallen back into the 40s or low 50s. South of the front, temperatures are generally in the 60s. The severe threat is over across our local area, with any remaining instability now located well south of our area. Aloft, a SW to WSW flow will stay in place as the upper trough axis lags well to the W (across the lower OH/TN Valley). This will keep transporting deep moisture from the Gulf into the local area into the first part of the night, lingering until ~3AM across the SE zones. In addition, an upper level jet (~180 kt at 250 mb), extends from northern New England back to the SW across the OH Valley, which will keep much of the local area in the favorable RRQ upper divergent zone. Plenty of moisture is in place to support moderate to heavy rain given PWATs analyzed at 1.5-1.6" roughly along the sfc boundary. All of these features will keep the threat for moderate to locally heavy rain going across much of the area. Expect the usual issues in urban and poor drainage/flood-prone and WPC has much of the area (south of a Farmville- Richmond- Melfa line) in a Day 1 Marginal ERO. Cold 1028+mb high pressure and an UL trough will build east late tonight, nudging the front off the SE VA/NE NC coast by Tuesday morning. A secondary front will bring gusty NNW winds late. Drying out with some partial clearing late. Lows late tonight/Tues morning will be in the mid 30 in the NW, and mainly 40-45F elsewhere. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/... As of 345 PM EDT Monday... Key Messages: - Dry conditions prevail Tuesday through Wednesday. - A Freeze Watch has been issued for much of the FA for Tue night/Wed AM away from the coast. (Note the far NW is not yet active in the Frost/Freeze Program so despite a hard freeze no Headlines will be issued there). Chilly highs on Tues average 10-15 deg F below normal, ranging through the 50s (cooler N, warmer S). Atlantic coastal portions of the MD Eastern Shore may even stay in the upper 40s. Gusts up to 35 mph expected near the coast, 20-30mph inland. Diminishing winds, and the incoming cold, dry airmass will make for an excellent radiating night Tuesday night. Freeze Warnings are in effect for much of the (inland) area that is active in the frost program (i.e. all but the far NW corner of the CWA from Prince Edward northeast to Caroline County). Lows in the mid- upper 20s expected away from the immediate coast to low- mid 30s coastal areas. Milder but still on the cool side Wed, with highs in the mid- upper 50s under a partly to mostly sunny sky. Clouds increase ahead of the next system Thursday, with chc PoPs moving into the NW by late morning/aftn. Milder with highs in the 60s (near 70F SE). && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... As of 355 PM EDT Monday... Key Messages: - Another chance for rain comes on Friday into Saturday as another front moves through the forecast area. - Temperatures will be seasonable for the upcoming weekend into early next week. Chances for rain increase Thu night and continue into Friday. Uncertainty increases as the global models diverge for the weekend period. While there is decent alignment about a deep sfc trough sliding over the east coast, there is disagreement regarding the formation of a sfc low in the vicinity of the FA. Where the prospective low tracks, the timing, and the strength of the system will ultimately decide precip chances and winds. The general consensus is for chc PoPs Thu night, with rain likely Friday. Temps should generally be in the 60s regardless, with the models all drying us out by Sunday, with a warming trend into Monday as a strong ridge over the plains slowly building eastward. && .AVIATION /00Z TUESDAY THROUGH SATURDAY/... As of 800 PM EDT Monday... A cold front will continue to drop south into tonight. This will result in a prolonged period of moderate to heavy rain through this evening, with lower VSBYs in heavier showers. IFR CIGs have taken hold at all terminals outside of ECG which is still holding onto VFR CIGs. ECG will see CIGs drop to IFR over the next couple of hours as the front progresses further to the south. CIGs begin to increase again around or shortly after 06z from NW to SE as drier air filters back into the region. All sites return to VFR by or shortly after sunrise Tuesday morning. Winds become northerly all areas by later evening, with a gusty NNW wind expected starting after ~06Z. Gusts Tuesday will avg 20-25KT, with ~30KT at SBY. Outlook: VFR conditions will prevail through Thursday ahead of another approaching front late this week. Flight restrictions are likely Friday in showers. && .MARINE... As of 320 PM EDT Monday... Key Messages: - Strong SCA conditions are expected Tuesday/Tuesday night over all zones, with a brief period of gale force gusts possible, especially across the north. A cold front is slowly dropping south across southern portions of the local waters this afternoon. N of the boundary, winds are generally N/NE at 10-15kt. S of the boundary, SW winds are a little higher at 15-20kt. Additionally, showers and thunderstorms associated with the front are bringing briefly elevated gusts and Special Marine Warnings are being issued as necessary. The strongest storms will impacts southern coastal waters and the Currituck Sound this afternoon. The initial front will exit the forecast area this evening. Behind it, a brief surge of NW winds up to around 15kt is expected. This initial surge has trended a little stronger with today`s guidance, so went ahead and extended the SCA for the lower bay to start it earlier to cover it (now starting at 7pm). Also started the SCA for the Currituck Sound earlier (now in effect), since winds ahead of the front over-performed a bit near the sound. There will likely be a short lull in the winds over the sound this evening before the main surge of NW kicks in. Later this evening/tonight, a secondary cold front will push through the region. Strong CAA behind the front will bring another surge of NW winds to local waters late tonight through tomorrow morning. These winds increase to about 25kt with gusts to 30kt across most waters by 12z Tues (~20kt in the rivers/sound). May see an hour or two of gusts to around 35kt in the upper bay and MD coastal waters early tomorrow morning. Winds diminish some to 15-20kt later in the morning Tues as high pressure starts to build in. The NW winds will remain in this range until Tues night/Wed morning when high pressure slides in overhead. Sub-SCA conditions are forecast Wed morning through Thursday morning. Additional SCAs may be needed Thurs when another frontal system impacts the region. Seas are 3-5ft this afternoon and will increase to 5-6ft late tonight/tomorrow morning. Waves in the bay are about 2ft and will increase to 3-4ft tonight. Waves in the river/sound will be ~2ft. Waves diminish to 2-3ft tomorrow afternoon as seas diminish to ~4ft. Seas then gradually drop to 2-3ft by Wed evening. Waves will be 1- 2ft Wed through Wed evening. && .AKQ WATCHES/WARNINGS/ADVISORIES...
