NWS Wakefield, VA wrote its last area forecast discussion before the first event at Aug 11, 3:05 PM EST, 2 hours earlier.
Area Forecast Discussion National Weather Service Wakefield VA 405 PM EDT Sat Aug 11 2018 .SYNOPSIS... A trough of low pressure will approach the region from the west tonight through the weekend...bringing a period of unsettled weather to the region through early next week. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... As of 400 PM EDT Saturday... An upper-level trough is clearly visible on WV satellite diving southward across Great Lakes region. This has put much of the Mid-Atlantic and Northeast CONUS in moist SW flow (PW values above 2" in spots). Numerous showers and thunderstorms have developed from NC to New England this afternoon. Closer to our CWA, t-storms have developed across southern VA and NE NC along and southeast of a weak surface boundary. Some areas have seen heavy rainfall as the thunderstorm activity has been relatively slow moving. Another area of showers/t-storms has developed from northwestern VA to southern PA along a secondary front to the north. In between, the northern half of the CWA has seen very little t-storm activity this afternoon. Expect the t-storms in southern VA/NE NC to slowly move to the east through this evening before starting to diminish after sunset as daytime heating (and therefore instability) is lost. CAM guidance is forecasting most of the area to remain dry (with perhaps a few isolated showers) after 04z (midnight EDT) tonight. Areas north of a Farmville to Williamsburg line will only see isolated to scattered t-storms through 04z tonight. Maintained likely PoPs from srn VA to NE NC to account for the t-storms currently moving through, with chance PoPs elsewhere through this evening. Kept PoPs between 10-40% (lowest NW, highest in NE NC) in all areas after midnight. There is a chance that the storms in NW VA will impact the far western CWA from now through 03z (11 PM) before weakening, so kept PoPs between 40-50% in these areas through 9 PM. While widespread severe weather is not expected, any t-storm will have the potential to produce minor flooding in poor drainage areas. Overnight lows will be in the low-mid 70s throughout the region. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/... As of 400 PM EDT Saturday... Previously referenced Great lakes upper trough will linger over the Ohio Valley tonight through Sunday before slowly moving east Mon/Tue. The latest 11/12z NAM/GFS/ECMWF/CMC remain in relative agreement regarding the evolution of this feature (as well as the placement of surface frontal boundaries). Expect the upper low to move very little through Monday, keeping us in moist SW flow as a (weak) cold front meanders over the southeastern CWA (and the secondary front sits over western VA). Therefore, expect two areas of showers/t-storms to develop Sunday afternoon (most of the CAMs depict this scenario). One area will develop from southern VA to NE NC and another will form over far western VA. Expect the showers/t-storms over western VA to slowly move toward the western part of the CWA late Sunday afternoon through Sunday evening. Am expecting the rain to diminish somewhat in intensity Sunday night. However, scattered to numerous showers will be around (especially north and east) from Sunday night-early Monday morning, as the upper trough axis will be located just west of the CWA and several shortwaves will be rotating through the region. Additional t-storms are expected to develop Monday afternoon (most numerous over eastern portions of the area) as the upper trough axis enters the western part of the CWA. The upper trough finally moves northeast of the region by the end of the day on Tuesday. However, isolated to scattered (diurnally driven) showers/t-storms are possible across the region on Tuesday. At this time, it appears that most areas will be dry for a change on Tuesday. Again, while both Sunday and Monday will not be completely washed out, periods of locally heavy rain will again be possible with any showers/t-storms that form, and will continue to note this potential in the HWO. Expect highs in the mid-upper 80s and lows from around 70 to 76 throughout the area from Sunday through Tuesday. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... As of 330 PM EDT Saturday... Latest GFS/ECMWF remain in pretty good agreement w/ a drier period developing for Wed/Thu as upper ridging/weak high pressure builds across the region. Trough develops to the west again during Fri, with increasing moisture/ PoPs returning for Fri/Fri night. Models currently push the front through most of the CWA Sat, but given the time of year, opted to keep at least chc for aftn tstms most areas on Sat w/ partly cloudy skies. With more sunshine and slightly lower dew pts Wed, highs will avg into the upper 80s to around 90 F, then into lower 90s most areas for Thu. Highs Fri and Sat will then drop back a few degrees with more clouds and higher PoPs, ranging from the upper 80s to lower 90s Fri and in the upper 80s Sat. Lows ranging from the mid 60s to mid 70s. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... As of 330 PM EDT Saturday... Scattered/numerous showers/tstms over the region this aftn, with coverage generally greatest over southern VA and NE NC through early this evening. The potential exists for at least brief flight restrictions at all TAF sites and have TEMPO groups with IFR vsbys at KORF/KPHF/KECG. Conditions will be VFR outside of the convection with SCT/BKN cumulus. Winds will generally remain light and out of the south through tonight. Some uncertainty for Sun morning, but overall low stratus is expected to be primarily west of the terminals so will have VFR conditions in the TAFS except a period of MVFR at KRIC. Outlook: Unsettled conditions will continue through at least Monday with the continued chances for sub-VFR conditions with any heavier showers or storms. Improving conditions and decreased chances for precipitation are expected by middle to late next week. && .MARINE... As of 330 PM EDT Saturday... Relatively benign marine conditions through the forecast period. Winds are generally out of the south, ranging from 5 to 15 knot. Seas are 1 to 2 feet and waves are around 1 foot. A frontal boundary remains stalled just west of the waters into Monday allowing for winds to average 5 to 10 knots from the SE to the SSW. Seas will average 2 to 3 feet and waves in the Bay at 1 to 2 feet. The boundary finally pushes east Tuesday into Wednesday as a weak cold front allowing for a slight uptick in winds. High pressure briefly builds over the waters Wednesday night and Thursday. && .AKQ WATCHES/WARNINGS/ADVISORIES... MD...None. NC...None. VA...None.
