749 FXUS61 KAKQ 240702 AFDAKQ AREA FORECAST DISCUSSION National Weather Service Wakefield VA 302 AM EDT Fri May 24 2024 .SYNOPSIS... A weak cold front will drop across the area today into this evening. A surface trough will affect the region Saturday into Saturday evening. A warm front followed by a cold front will affect the area late Sunday into Monday night. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... As of 905 PM EDT Thursday... A weakening cold front will approach the area from the NW this tonight. Showers and thunderstorms have struggled to initiate or move into the region this evening. Latest radar shows some showers in NE NC, but otherwise dry. A few CAMs hint at some redevelopment in the SE later tonight into early tomorrow morning, but confidence is rather low at this point. Outside of isold/wdly scattered storms through the evening hours, expect at partly to mostly cloudy sky overnight with lows in the 60s. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SATURDAY/... As of 330 PM EDT Thursday... The aforementioned weak front will stall out across the local area on Friday. 12z NAM and HRRR are showing the potential for scattered showers/storms during the morning before clearing and then additional isold showers/storms developing in the afternoon. Remainder of the guidance favors the afternoon/evening for any showers/storms. Forecast still favors highest PoPs on Friday after 18z (15-20% NE to 30-40% S). Remaining summer-like and rather warm Friday with highs in the mid to upper 80s inland, and upper 70s to lower 80s at the coast due to a developing sea-breeze in weak flow. Mild Friday night with lows in the 60s. 23/12z guidance has some broad consistency in showing shortwave energy arriving Saturday in westerly mid/upper level flow, with the boundary lifting back to the N, but confidence in the details remains low. Given this, PoPs for mainly afternoon/evening showers/tstms are 30-50% across the entire area. Highs Saturday will once again be in the mid 80s, with upper 70s to lower 80s toward the coast. && .LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... As of 330 PM EDT Thursday... Key Message: - Remaining warm and humid Sunday into Memorial Day with the potential for showers and thunderstorms Memorial Day. Continued warm and humid Saturday night with any showers/tstms diminishing in coverage as shortwave ridging arrives in the westerly flow aloft. Lows will mainly be in the 60s. Highs Sunday will once again be in the mid 80s inland with upper 70s to lower 80s toward the coast. Less coverage of showers/tstms are expected Sunday afternoon/evening as broad ridging prevails, with PoPs less than 10% NE to ~30% SW. 23/12z EPS/GEFS depict an anomalous trough digging from the Great Lakes to the Northeast Monday through Wednesday with a cold front pushing through the Mid-Atlantic. Confidence on timing remains on the low-side, but given the strength of the trough more coverage of showers/tstms are possible in the Memorial Day/Monday night timeframe. Highs Memorial Day will once again be rather warm in the mid 80s to around 90F (slightly lower at the coast), with highs trending down into the upper 70s to lower 80s toward the middle of next week with drier air also arriving into the region. && .AVIATION /07Z FRIDAY THROUGH TUESDAY/... As of 225 AM EDT Friday... Isolated to sctd showers/tstms were affecting scntrl/SE VA and NE NC very early this morning well in advance of a weak cold front. The TAF sites PHF/ORF/ECG will likely receive a shower or tstm through 09/10z this morning. Brief MVFR CIGS or VSBY restrictions will be possible with any pcpn. Otherwise, mainly VFR conditions will prevail. A weak cold front will drop across the area today into this evening, producing sctd showers or tstms at any TAF site. Brief sub-VFR CIG or VSBY restrictions will be possible in any heavier showers or storms. A surface trough may produce isolated to sctd mainly aftn/early evening showers or storms during Sat. There is the potential for more widespread coverage of showers/tstms Mon into Mon evening, as a cold front pushes into and across the region. && .MARINE... As of 300 AM EDT Thursday... Key Messages: - Benign conditions expected on the waters through Sunday. - Chances for showers and storms (especially in the afternoons and evening) later today and again on Monday afternoon. A weak cold front washes out later this morning as it drops into the area. More widespread showers and storms are crossing over northern NC this morning in association with some shortwave energy crossing to our south. Showers and storms will likely push across the lower Bay and out coastal waters south of Cape Charles before sunrise before weakening. High-Res CAMs are showing chances for additional showers and storms this afternoon. Marine interests should be monitoring the potential for these storms after 2pm this afternoon, with potential W-NW t-storm outflow crossing the waters later this afternoon and evening. Otherwise, high pressure just offshore will push farther offshore into the upcoming weekend. This should result in a stretch of rather quiet/benign marine weather conditions late today through the upcoming weekend. Expect winds of 5-15kt outside of any storms through Sunday. Seas ~2 ft over the ocean/waves 1-2 ft in the bay. Afternoons will likely be dominated by sea breeze circulations each day, allowing winds to become onshore during those times, with south to southeast winds returning in the later afternoon and evening/late night hours. A cold front approaches the area on Monday associated with a deepening low pressure center over the Great Lakes. Have continued with winds of 10 to 15 kt over the Bay, 15 to 20 kt over the open ocean on Monday, still below Small Craft Advisory criteria. Winds veer around to the NW behind the front on Tuesday into midweek. Some additional showers and storms will be possible on Memorial Day Monday ahead of the approaching cold front. E-SE swell behind that system that could bring some 5 foot seas by Monday night. However, seas quickly subside as winds turn back offshore Tue-Wed. Low Rip Risk on area beaches today and tomorrow. && .AKQ WATCHES/WARNINGS/ADVISORIES... MD...None. NC...None. VA...None.
