The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Wakefield, VA wrote its last area forecast discussion before the first event at May 24, 8:06 AM EST, 2 hours 4 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wakefield VA 906 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 through Monday night. && .NEAR TERM /THROUGH TONIGHT/... As of 900 AM EDT Friday... Mid-morning sfc analysis shows a stationary frontal boundary extending from the Midwest states eastward into the nrn Mid- Atlantic. Weak lee troughing is also noted E of the Appalachians. Aloft, shortwave energy is sliding eastward through the area. Currently noting two areas of rather widespread rain/convection. The first is across SW portions of the FA, with embedded areas of heavy rain and thunder slowly progressing E. The second is over NE NC, which currently has more lightning activity where slightly higher instability is present. Radar shows a slow N/NE progression w/ northward moving outflow. CAMs are handling both of these areas poorly but current thinking is highest PoPs should focus over NE NC and srn VA through most of this morning. A weak cold front will drop across the area today into this evening, producing more isolated to sctd showers or tstms from later this morning into this evening. However, coverage and intensity will depend on the degree of aftn destabilization in the wake of the ongoing (morning) convection. More clouds today will result in not as warm temps across the area. Highs today will be in the upper 70s to lower 80s. Pcpn will end by late this evening, with a mostly clear to mostly cloudy sky expected tonight into early Sat morning. Lows tonight in the lower to mid 60s. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... As of 355 AM EDT Friday... A sfc trough with some shortwave energy will push into the region for Sat aftn/evening, resulting in 20-50% PoPs. Highs on Sat will be in the lower to mid 80s. Pcpn will taper off or end later Sat evening. Lows Sat night in the lower to mid 60s. A warm front will affect the area later Sun through Sun night. Partly to mostly sunny, warm and humid on Sun with highs in the mid to upper 80s most locations (upper 70s to lower 80s near/at the coast). Slight to small chance for aftn/evening showers or storms. Then, PoPs will increase a bit more from the WNW late Sun night into early Mon morning, as a cold front starts to push ewrd toward the mtns. Lows Sun night mainly in the lower to mid 60s once again. && .LONG TERM /MONDAY THROUGH THURSDAY/... As of 410 AM EDT Friday... 00z/24 EPS/GEFS depict an anomalous trough digging from the Great Lakes into the NE Mon into Thu with a cold front pushing through the Mid Atlc Mon night. 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/Mon night timeframe. Highs Memorial Day will range through the 80s. Lingering frontal boundary or troughiness will result in slight or small chance for showers or a tstm Tue and Wed, even though slightly drier air will be filtering into the region. Much drier air then expected for Wed night through Thu, as high pressure starts to build in from the NW. Highs will be in the lower to mid 80s Tue, in the mid 70s to lower 80s Wed, and in the lower to mid 70s Thu. && .AVIATION /13Z FRIDAY THROUGH TUESDAY/... As of 655 AM EDT Friday... 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. There may be IFR CIGs or VSBYs late tonight into Sat morning, esply at ECG. 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 Friday... Key Messages: - Benign conditions expected on the waters through Sunday. - Chances for showers and storms (especially in the afternoons and evening) each afternoon through Memorial Day. 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. There will also be the chance for scattered afternoon and evening showers and storms each day through Monday. 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 more widespread 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.
