405 FXUS61 KAKQ 111057 AFDAKQAREA FORECAST DISCUSSION National Weather Service Wakefield VA 657 AM EDT Sat Oct 11 2025
.SYNOPSIS... A coastal low tracks north toward the area today into tonight, passing nearby Sunday, and lingering offshore into Monday. Heavy rain, windy conditions, and coastal flood impacts are likely near the coast tonight and Sunday. The low moves away by Tuesday as high pressure builds across the Great Lakes. Dry and seasonable weather returns and prevails for the middle and end of next week.

.NEAR TERM /THROUGH SUNDAY/... As of 655 AM EDT Saturday...
Key Message:
- A coastal storm impacts the region later today into Sunday, bringing moderate to locally heavy rainfall, gusty winds, and moderate to major tidal flooding. Impacts will be greatest at the immediate coast, and from late tonight through midday Sunday.
A complex surface pattern resides over the eastern CONUS this morning. High pressure is now centered to the east and well offshore of New England. However, it continues to ridge SW into the Mid- Atlantic and Carolinas, keeping us mostly dry for now. The main wx story over the next few days is the developing sfc low offshore of FL, with the latest analysis placing its central pressure around 1004 mb. For the first part of today, the dry wx should mostly continue, outside of a brief shower or two in NE NC and srn VA. Skies will be mostly cloudy to overcast with high temperatures in the upper 60s to lower 70s. The coolest temps are expected in the Piedmont where lower-level clouds should reside for most of the day. As the low tracks northward this afternoon, rain will gradually increase in coverage, first over SE VA and NE NC in the mid-late afternoon and then elsewhere this evening and tonight. QPF through 8 PM this evening will be on the lighter side, generally 0.25" or less.
The brunt of the impacts from the coastal low are still anticipated tonight through Sunday. The initial sfc low offshore of the Carolinas should lift northward toward at least the srn NC coast tonight. Beyond that time, there is STILL a good deal of spread in the model guidance and ensembles surrounding the evolution of the low(s). There are generally two camps in the guidance: 1) the initial sfc low to our S remains the primary feature and moves northward along the coast and potentially inland into NC and 2) a new low becomes the primary low off of the the northern Mid-Atlantic and New England coasts, with a sprawling, bifurcated feature taking over by later Sunday and Monday. The first scenario would generally portend to more significant impacts across coastal portions of the local area (especially in the wind and coastal flooding department), while the second scenario would be more impactful for those located NE of our forecast area. Overall, though, the EPS and GEFS are in better agreement with the 00z/11 model cycle. This brings moderate to locally heavy rainfall northward tonight into Sunday morning, with the highest QPF over NE NC and srn VA during the 3 AM- 10 AM timeframe. Am rather confident that our entire forecast area sees rain by Sunday morning with 80-90% PoPs areawide. Continuing the trend from the previous shift, QPF has continued to trend down and the highest totals remain focused well of E I-95, with a wide swath of 1-1.5". SE VA and NE NC have the best chance of seeing 2"+, though EPS and GEFS probs drop off to nearly zero for 4"+. It`s still important to mention that some CAMs are more aggressive in showing heavier rainfall extending further inland. Oppositely, rain totals would be quite a bit lower than our forecast shows should a solution like the 00z ECMWF verify. No Flood Watches given persisting uncertainties, totals trending lower, and dry antecedent conditions.
Winds will also increase as the low moves north and the highest winds are expected just N of the elongated sfc low feature and coastal front. The highest winds are expected late tonight for coastal NC and VA, shifting north to the Atlantic-facing side of the VA and MD Eastern Shore after sunrise Sunday morning. Forecasted wind gusts at the immediate coast are 45-55 mph, with some potential for 40-45 mph gusts a bit inland into southside Hampton Roads and on the MD Eastern Shore (toward Salisbury) as well. Wind Advisories have been issued for portions of Hampton Roads and the Peninsula/middle Peninsula, as well as the NC OBX. There is enough probability for 55mph+ gusts at the immediate coast from VA Beach northward along the coastal counties on the Eastern Shore that a High Wind Watch has been issued (confidence was too low at this time to go with High Wind Warnings).
Rain lingers through the rest of Sunday as the large low feature remains near the area, though the rain intensity should really drop off by the later afternoon and evening. The winds will also slowly subside, but remaining breezy to windy near the coast.

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/... As of 320 AM EDT Saturday...
Key Messages:
- A lingering coastal low offshore will lead to continuing chances for rain and breezy conditions Monday.
- Slowly drying out Tuesday as the low finally departs well offshore.
The upper pattern is not very progressive and favors a stagnant pattern through at least Monday as a sprawling upper low rotates around itself. Thus, uncertainty is rather high as the model solutions really diverge with respect to the evolution of the lingering coastal low(s). The 00z ECMWF solution now rotates the low offshore of Long Island SW into the DelMarVa coast Monday afternoon, albeit it`d be quite weak at that point. Either way, some sort of low will be offshore/nearshore with continued breezy and unsettled conditions, especially for northern portions of the area and those at the coast. Mainly dry wx and mostly cloudy skies are currently anticipated inland, but this is subject to change. High temperatures range from the mid 60s to around 70 F, with lows Monday night in the 50s.
Upper heights then build into Tuesday, forcing the sfc and upper low offshore and away from the area. High pressure over the north- central CONUS also begins to build SE into the Great Lakes. A lingering shower or two is possible at the immediate coast; otherwise, mostly dry Tuesday with mostly cloudy skies E to partly- mostly sunny inland. Seasonably cool conditions persist, with cooler temps E (upper 60s) and milder well inland (lower 70s).
&&
.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/... As of 320 AM EDT Saturday...
Key Message:
- Dry and seasonable for the middle and end of next week.
The synoptic pattern heading into the middle of next week favors a tall ridge axis to our W. This should keep sfc high pressure N and NW of the area with mostly dry conditions. A bit milder Wednesday with highs in the low-mid 70s, along with a return to mostly sunny skies for the entire area. An upper trough may then dive southward later Wednesday into Thursday of next week, bringing cooler temps by Thursday and Friday. Overnight lows follow a cooling trend through this period starting with 50s Tuesday night and dropping to the low 40s by Thursday night.
&&
.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/... As of 650 AM EDT Saturday...
Widespread cloud cover with a mix of VFR and MVFR CIGs are noted over the area this morning. Flight conditions further degrade to widespread MVFR later this afternoon and then IFR tonight as a coastal low approaches the region. Rain will also overspread the southern terminals this afternoon and then RIC and SBY by this evening and tonight, reducing visibility. Spotty rain or showers are also possible earlier than the prevailing wx groups indicate in the TAFs, so will continue mention of this with PROB30 groups. N-NE winds of 5-10 kt this morning increase to ~10 kt inland and 10-15 kt with gusts up to 20-25 kt near the coast this afternoon. Winds increase further after 00z and especially after 06z, with some potential for 30-40 kt gusts at coastal terminals through and after 12z Sunday. Rain continues through tonight.
Outlook: MVFR/IFR (mostly IFR) CIGs, elevated winds, and moderate to heavy rain are all likely Sunday as low pressure persists just offshore. Degraded flying conditions (widespread IFR CIGs) likely continue into early next week with rain chances lingering through Monday.
&&
.MARINE... As of 600 AM EDT Saturday..
Key Messages:
- Small Craft Advisory conditions persist across most of the local waters today.
- Low pressure intensifies south of the area tonight. Gale and Storm Warnings go into effect later tonight through Sunday/Sunday night. Winds remain elevated Monday and Tuesday as the low is slow to move away from the region.
Early morning analysis shows ~1028 mb high pressure well off the New England coast, with developing low pressure off the east coast of Florida. Winds range from 10-15 kts across the northern Ches Bay and coastal waters to 15-25 kt from roughly Cape Charles to the south. Seas follow a similar pattern with 4-5 ft seas N and 6-8 ft from VA Beach southward. Waves in the bay are 2-3 ft with 3-5 ft near the mouth of the Bay.
No major changes with respect to the overall evolution of the coastal low off the coast of FL/GA today, which will track northward over or close to our waters later Sunday into Monday. While the exact evolution and timing is still somewhat uncertain, there is decent agreement that the system lifts up along the Carolina coast late tonight/early Sunday and becomes elongated from SW to NE during the day Sunday and Sunday night. This scenario results in a lengthy period of strong NE winds across the area, ramping up this evening with winds expected to peak across the region Sunday morning into early Monday. There remains high confidence for significant marine hazards, including high winds (potentially to Storm force for VA-MD Ocean waters) and dangerous seas. Peak wind gusts range from 45-50 kt on the VA-MD coastal waters and mouth of the Bay (where a Storm Warning is now in effect), 40-45 kt in the rest of the Chesapeake Bay and NC coastal waters, and 35-40 kt in the upper tidal rivers. With the broader/elongated coastal low, the progression through the region will be prolonged into Tuesday and potentially early Wednesday but with winds slowly decreasing to high-end SCA levels during that period. The gradient finally starts to relax by mid week with improving marine conditions. Seas are forecast to peak in the 15-20 ft range (sig wave height), with occasional waves up to 25+ ft. Sig Waves in the Chesapeake Bay range between 5-8 ft, with 9-10 ft possible at the mouth of the bay. As winds decrease next week, so will the seas, but only gradually.

.TIDES/COASTAL FLOODING... As of 600 AM EDT Saturday..
Later tonight through Sunday, as NE winds rapidly increase, likely to Gale to local storm force by early Sunday, a rapid rise in anomalies is expected (a surge increase of ~2-2.5 ft in ~12 hrs). The high tide cycle occurring late tonight into early Sunday is the lower astro tide, so even with a sharp increase, generally only minor flooding is expected during this period. The following high tide, occurring around noon Sunday along the Ocean, and through the aftn elsewhere is the anticipated time for peak water levels with this event. Widespread moderate to major coastal flooding is expected during this period from the northern Neck southward along the west side of the Bay and into the Rappahannock, York, and James rivers, as well as most locations along the Ocean. Coastal Flood Warnings are now in effect for these areas. Some minor flooding is possible with the high tide cycle tonight for areas along the Bay so some of the Warnings actually go into effect tonight (with the CFW product indicating the worst flooding to occur with the following cycle on Sunday). The highest probs for achieving Major flood thresholds will be the Ocean from NC OBX to VA Beach, and the mouth of the Bay areas, as well as portions up the James river. Precise water levels will be highly dependent on the track of the low and the associated wind direction, but confidence has increased this forecast cycle given better model agreement that a strong NE wind is likely to prevail through the Sunday tide cycle. The current forecast is for many areas in the lower Bay/James river to see flooding that has not been observed in at least a few years if not longer, with top 10 levels likely. Additional flooding is likely into at least Monday (possibly Tuesday), with the slower progression of coastal low pressure, though exact water levels become more uncertain given the potential for winds to diminish somewhat and to become northwesterly as the low moves away from the coast.
