NWS Wakefield, VA wrote its last area forecast discussion before the first event at Aug 28, 9:00 AM EST, 2 hours 50 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wakefield VA 1000 AM EDT Mon Aug 28 2023 .SYNOPSIS... A frontal boundary will slowly lift north through Tuesday leading to continued periods of unsettled conditions. A cold front eventually crosses the region Tuesday night into Wednesday. Tropical Storm Idalia is forecast to track off the Carolina coast later this week. High pressure returns late in the week into the weekend. && .NEAR TERM /THROUGH TONIGHT/... As of 1000 AM EDT Monday... GOES water vapor channels depict an upper jet from the central Appalachians to off the New England coast this morning. Meanwhile, a stationary front is located near the VA/NC border. Areas of locally heavy rain have developed over central and southern VA this morning immediately N of the front. Temperatures range from the lower/mid 70s NW to the lower 80s SE. The surface boundary continues to slowly nudge northward later this morning into this afternoon, as shortwave energy slides over the region aloft. Additionally, the boundary will be underneath the southwestern periphery of a ~100kt upper jet core from New England to Atlantic Canada. Forecast PW values from the early morning model runs still show high values (~2.1-2.3") Therefore, some locally heavy rain is definitely possible with rich moisture and forcing aloft, and the 00z/28 HREF has 30-50% probs for 3"/3hr in vicinity of the boundary from central to SE VA and NE NC. In addition, WPC has placed a majority of the area in a Day 1 Slight Risk ERO. However, there is still some disagreement between the various CAMs on both highest QPF amounts and coverage of the rainfall today. After discussion with neighboring offices, it was decided to hold off on any Flood Watches for the time being and to let the dayshift make the final call based on how everything evolves this morning. If a Flood Watch were to be needed, it would likely be targeted for the urban areas of Hampton Roads. Overcast skies are expected today with widespread showers and storms. Highs will range from the mid/upper 70s NW to the lower/mid 80s SE. Unsettled conditions are expected to continue into the first part of the night, before we likely see a diminishing trend in the rain (especially S/SE), as the front lifts further off to the NW. Low temperatures tonight will again range from the mid/upper 60s NW to the mid 70s SE. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... As of 330 AM EDT Monday... By Tuesday, the frontal boundary will be located a bit further inland (over the Piedmont). As a result, best PoPs on Tuesday will also be further inland, with likely PoPs over our NW counties by Tuesday evening. Once again, WPC has all of the area in a Day 2 Marginal ERO. Any of the area will have the potential to see localized flooding underneath any heavier showers or storms, especially if we see some flooding today as well. Meanwhile, Hurricane Franklin will be passing well offshore Tuesday through Wednesday leading to mainly just a rip current risk/high seas for us (see Marine section for details). The front pushes back to SE and offshore as a cold front Tuesday night into Wednesday, leading to slightly drier conditions (especially NW). All attention then turns to TS Idalia, with the latest NHC forecast having the storm make landfall somewhere in the bend of Florida Wednesday AM as a hurricane, and then taking the system off to the NE, located near or just off the GA/SC coast by Wednesday evening/night. As a result, rain chances increase across the SE portions Wednesday-Wednesday night as the system begins to draw in moisture up the coast. There will likely be quite the gradient in rainfall due to a strong area of high pressure that will also be trying to build in to our NW during the same timeframe. Right now, show likely PoPs across our NE NC counties and SE VA, dropping off to chance to the NW, we will likely see this gradient tighten as the forecast gets closer in time. For now, it appears the heaviest rain stays south of the immediate forecast area Wednesday- Wednesday night, but WPC will show a Marginal Day 4 ERO for the SE half of the area. Please continue to follow the latest from NHC on hurricane.gov in regards to the track of Idalia. && .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 330 AM EDT Monday... Idalia will remain the main focus for the extended forecast period. On Thursday, latest NHC track has the system moving NE along the southern NC coast and then quickly pushing out to sea by Thursday evening/night. Highest rain chances will remain across the SE third of the forecast area Thursday, and this will be refined as we get closer in time. Otherwise, breezy to windy conditions Thursday, especially near the coast, due to the gradient between Idalia and strong ~1020+mb high pressure building off to our north and northwest. High temperatures Thursday will only be in the 70s (despite the potential for sunshine inland) as a cooler airmass filters into the area. Idalia pulls further away Thursday night into Friday with high pressure/dry conditions building into the region for the upcoming weekend. && .AVIATION /14Z MONDAY THROUGH FRIDAY/... As of 645 AM EDT Monday... Showers continue to increase in coverage this morning into this afternoon. Widespread MVFR CIGs are expected to develop for all the TAF sites over the next couple of hours. Cannot completely rule out some pockets of IFR, especially with any heavier rain. Shower and thunderstorms will be possible through the afternoon and evening with MVFR CIGs continuing at all sites. IFR CIGs are possible early Tuesday morning, potentially lingering at or past sunrise Tuesday AM. Outlook: Unsettled conditions with a higher chc for showers, and few tstms, and flight restrictions continue into Tuesday. Somewhat improved conditions are expected Wednesday. There is a chc of rain by Thursday/Friday depending on the exact track of TS Idalia. && .MARINE... As of 420 AM EDT Monday... Early this morning, a nearly stationary boundary was draped across coastal NC, just to the south of local waters. Winds were E 5-15 kt across the waters, with waves 1-2 ft and seas 2-4 ft. Meanwhile, Hurricane Franklin was well east of the FL eastern coast, and is still fcst to pass well E of the SE and Mid Atlc coasts from later this morning through Wed. While, Tropical Storm Idalia was about 150 miles south of the western tip of Cuba. The stalled front will slowly lift northwest of the marine area for later today through Tue, resulting in E winds shifting to the SE or S at 5-10 kt. The front will then push across the waters during Wed, with the winds shifting from WSW to the NW or N. Swell from Hurricane Franklin is set to arrive Tue though, so SCAs for the coastal waters for seas will likely start by late Tue morning. Seas will build to 5-6ft (7ft at 20nm) by Tue evening. Attention then turns to Idalia for Wed night into Fri. Current forecast has a Tropical Storm passing to the south of the local area. However, the combination of strong high pressure to the north and the tropical storm fcst to pass by to our SSE and off the coast, strong to very strong NE winds will be likely across our marine area, esply the srn waters. NE winds 15-25kt with gusts to 30-35kt will be possible from late Wed night through Fri morning. Waves could build to 3-6 ft in the Ches Bay and Rivers, and seas could build to 6-10 ft. There will be a high rip current risk for northern beaches today and moderate risk for southern beaches. Elevated rip current risk is likely through the week given the combo of onshore flow, arriving swell, and increased winds late in the week. && .AKQ WATCHES/WARNINGS/ADVISORIES... MD...None.
