324 FXUS61 KAKQ 280750 AFDAKQAREA FORECAST DISCUSSION National Weather Service Wakefield VA 350 AM EDT Sun Sep 28 2025
.SYNOPSIS... Cooler and drier day is expected as the slow moving cold front finally pushes offshore this afternoon. Tropical Depression Nine is expected to become a hurricane as it tracks north off the Southeast coast through Tuesday. While the center of the low is not expected to be near the local area, rain from the system is expected to overspread the local area Monday into Tuesday. However, uncertainity remains high regarding rainfall totals given uncertainties regarding the exact track of the system. High pressure builds in by late week with cooler and drier weather likely.

.NEAR TERM /THROUGH MONDAY/... As of 330 AM EDT Sunday...
Key Message:
- Low level stratus and patchy fog will continue through this morning.
- Clouds will clear in the afternoon with drier conditions.
Early morning analysis shows a weak upper low centered over much of the area with more SW flow aloft. At the surface the slow moving cold front has finally pushed through most of the area and is now stalled along the coast. Behind the front some low level moisture remains in place allowing for low level stratus to form and engulf the entire CWA. Temperatures as 2am are in the middle 60s inland and upper 60s and lower 70s along the coast and across the southeast. Through the rest of the morning some patchy fog could develop across the area and the low level stratus will continue. This will put a halt on temperatures lowering much and by sunrise temperatures will continue to be in the middle 60s inland and upper 60s low 70s along the coast. Through the day the upper low will move further south but will remain over the east coast. At the surface, the slow moving cold front will continue to push further off the coast. With the front pushing further east this will allow for any showers to develop off the coast. Recent guidance does continue to show drier solutions and less coverage of any shower behind the front. Chances of thunder have been taken out of the forecast as the air behind the front will be stable. The low level stratus will start to erode further west this afternoon but the majority of the area will remain cloudy with little breaks in the clouds. Temperatures will not warm much and have been knocked down a degree or two due to the stratus deck. Highs this afternoon will be in the middle 70s across much of the area and upper 70s along the coast and to the far west. For tonight most if not all of the area will remain dry with the best chance of showers across NE NC closer to the front. Lows tonight will be in the low 60s inland and middle to upper 60s across the SE.

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/... As of 330 AM EDT Sunday...
Key Messages:
- Chances of rain will increase Monday through Tuesday as outer rain bands from TD-9 (expected to become Hurricane Imelda) overspread the region.
- Breezy conditions are expected Tuesday along the coast.
By Monday the upper low will have weakened substantially. At the surface the stalled frontal passage will be will continue to linger off the SE coast. Further south two tropical systems will continue to nudge north but remain out of our area. TD- 9 is still progged to become Hurricane Imelda by late Monday off the Florida coast. Across our are there could be some showers associated with this tropical system and could bring some locally heavy rain fall at times . Pops in the afternoon increase to 25 to 40% along and N of I-64 and 40 to 60% south. The chances for heavier rain fall is expected to be across the far southern portion of the area. Overall around .25" is expected across the south with these rain band with some possible higher amounts nearing .5". WPC has maintained a marginal ERO for the south for locally heavy flooding. Highs for Monday will be in the middle lower to middle 70s. By Tuesday, TD-9 is expected to stall further south off the coast of SC/GA/FL before eventually turning out to sea. Across our area high pressure will be building in out of the north assisting in keeping the chances of rain further across the south. Additional rain amounts across the south will be between .25" and .5" in the early morning hours of Tuesday. Then by Tuesday afternoon and early evening rain chances start to lower as TD-9 moves out to sea. WPC has maintained a marginal ERO for the south for locally heavy flooding. In addition to the rain chances Tuesday, breezy wind conditions are expected along the coast with wind gusts between 25 to 35mph. Highs for Tuesday will be in the low 70s.

.LONG TERM /WEDNESDAY THROUGH SATURDAY/... As of 330 AM EDT Sunday...
Key Messages:
- Drier and cooler weather is expected by the end of the week.
-Breezy NE winds will continue with gusts nearing 40mph by Wednesday.
Cooler and drier air will advect into the area by the middle to late next week and a strong high pressure moves over New England and the Mid-Atlantic. The pressure gradient on Wednesday from the high pressure to the north and the two tropical systems to the east and south will be quite strong along the coast. This will allow for breezy conditions lasting from Wednesday to Thursday. Wind gusts along the coast will be 30 to 35mph with some isolated gusts upwards of 40mph and 20 to 25 MPH inland. these conditions will be very similar through Thursday. Then by Friday the pressure gradient will weaken and the winds will decrease. Temperatures will overall be pleasant through the middle and late week. Highs will be in the low 70s Wednesday and upper 60s Thursday and Friday. Lows temperatures will plunge down into the middle to lower 50s Wednesday and upper 40s to low 50s Thursday.

.AVIATION /07Z SUNDAY THROUGH THURSDAY/... As of 139 AM EDT Sunday...
A mix of IFR and LIFR conditions have been noted across all terminals this morning. CIGS is the main concern this morning as low level clouds are continuing to move in across all terminals. These conditions will last through the 6z TAF period. Some patchy fog may develop later this morning that could cause brief Mvfr to IFR VIS restrictions. Winds tonight will remain light and variable. After sunrise CIGS should begin to lift to MVFR across all terminals. Some showers are possible across the far SE and should not affect the terminals. Winds will pick up out of the NE to 5 to 10 kt by mid to late morning.
Outlook: Sub-VFR CIGs likely linger across the terminals Sun. There is a low chance for a few showers across SE VA/NE NC Sun. Periods of sub-VFR conditions are possible through the week with rain chances increasing Mon.

.MARINE... As of 325 AM EDT Sunday...
Key Messages:
- Sub-SCA conditions through the weekend.
- Deteriorating conditions and building NE winds are likely next week, with the strongest winds expected Wednesday/Thursday.
- Follow the latest information from the National Hurricane Center regarding the progress of Humberto and Tropical Depression 9.
Latest analysis indicates 1012mb sfc low pressure just offshore of the Delmarva coast. A weak sfc boundary extends SSW just offshore of the SE VA/NE NC coast. Winds are NW 10-15kt, with some gusts to around 20 kt over the bay south of New Point Comfort. Seas are 2-3 ft, with waves 1- 2 ft.
Noting a modest surge in the Ches Bay, as high pressure builds west of the waters. This surge allows some gusts to ~20 kt to persist through mid-morning, but still not anticipating predominate SCA conditions. Otherwise, weak high pressure continues to build in today and tonight. Winds turn to the NNE and diminish to 5-10 kt (highest lower bay and central/southern waters. Waves 1-2 ft, seas remain 2-3 ft.
Attention then turns to the progression of Tropical Depression 9, possibly soon to be Tropical Cyclone Imelda. Emerging consensus amongst deterministic models and multi-model ensembles regarding the handling of this system, reflected well in the latest National Hurricane Center forecast track for the system, shows the system offshore of the east coast of Florida Monday, moving to a position ~200 miles off the SE Georgia/ N FL coast by Tuesday morning. As noted previously, this slower track allows for greater influence on TD9 from powerful Hurricane Humberto, a category 5 storm farther out in the central Atlantic early this morning. The latest track on Humberto shows the system increasing speed NW and remaining well offshore. Over the past few model cycles, the trend toward Humberto pulling TD9 farther and more abruptly offshore has steadily gained greater support, and that trend has continued with the 00z/28 cycle. However, we must caution this is still not yet a high confidence forecast, and continued vigilance with these systems is strongly advised.
In any scenario, Humberto will send increasingly strong long- period swell toward the local waters for much of the first half of the week ahead. This will translate to building seas late tonight into Monday, with that trend to continue through midweek. The tightening pressure gradient between the tropical systems to the SE and strong 1032+mb sfc high pressure pushing SE across Quebec will lock in a prolonged period of elevated NE winds this week. These gusty winds will be in addition to the developing high surf across our area due to the sharpening gradient and the incoming strong E-SE swell.
NE winds pick up to 15-20kt Monday and Monday night with seas increasing AOA 4-5ft. SCAs likely to be needed for tomorrow through late week. Winds and seas increase further Tuesday into Wednesday, with increasing potential for a period of gale force gusts early Wed morning, becoming more likely Wed afternoon into early Thursday. The strongest winds are expected over the southern coastal zones south of Cape Charles, including the adjacent Currituck Sound and the lower Chesapeake Bay. Seas are expected to build to 10-13 ft, with waves in the Bay 3-5 ft N and 5-6 ft S (6-8 ft at the mouth of the Bay). Winds gradually diminish by Friday, but headlines for elevated seas are expected to continue into next weekend.
&&
.TIDES/COASTAL FLOODING... As of 325 AM EDT Sunday...
Tidal departures remain minimal with no coastal flooding expected through Tuesday morning. After that, expect anomalies to steadily increase, as strong high pressure slowly drops SE across Quebec, while Humberto and Tropical Depression 9 (or its remnant), move farther offshore. The tightening pressure gradient will bring a prolonged period of strong onshore flow, and a high likelihood of at least minor coastal flooding late Wed through Friday (with the possibility for significant coastal flooding later Wed and Thu).
