011 FXUS61 KAKQ 230946 AFDAKQ AREA FORECAST DISCUSSION National Weather Service Wakefield VA 546 AM EDT Sat Aug 23 2025 .SYNOPSIS... Large waves, lingering coastal flooding, and dangerous rip currents will continue into the weekend from the distant effects of now post-tropical Erin. Dry conditions and seasonable temperatures are expected today, with a few showers and storms Sunday and Monday as a cold front approaches the area. Dry and very pleasant for the rest of next week with below normal temperatures. && .NEAR TERM /THROUGH TONIGHT/... As of 545 AM EDT Saturday... Key Messages: - Dry and warm today. - HIGH risk of rip currents continues at all area beaches through this weekend. Broad ~1020 mb high pressure is draped along the Mid-Atlantic coast this morning. The remnant post-tropical low of Hurricane Erin is located in the northern Atlantic, roughly at the same longitude as Newfoundland. With the high overhead, nighttime satellite imagery depicts mainly clear skies across the forecast area. However, some mid-level moisture on the western periphery of high is leading to scattered clouds across our NW counties, along with milder temps in the 60s. Rather ideal radiational cooling is occurring E of the clouds and temps have fallen into the mid 50s to upper 50s away from the coast, with low-mid 60s at the immediate shoreline. The high will settle offshore of New England by later this afternoon. This will allow for a modest increase in dew points as the low-level wind direction slowly veers to the SE. Cloud cover today will be a mix of lower-level cumulus from sfc heating and upper-level cirrus from an elongated sfc trough over the SE CONUS. High temperatures today will continue the trend of being a few degrees below normal with lower 80s for most of the area. Clouds increase across SE VA and NE NC further tonight. Otherwise, expect lows in the mid 60s inland and upper 60s/lower 70s near the coast. Also, a high risk of rip currents and dangerous swimming conditions are expected at area beaches through the weekend. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... As of 245 AM EDT Saturday... Key Message: - A few showers and storms possible Sunday and Monday. Otherwise, seasonable temperatures in the mid 80s are expected. A weak cold front will approach from the NW Sunday, but likely gets hung up just W of our CWA. To our south, the sfc trough/weak low lifts N along the NC coast as an upper trough begins to dig out of the Midwest. The frontal forcing, weak lee-side troughing, and increasing dew points should be enough to support a few showers and storms in the Blue Ridge and Piedmont Sunday afternoon. Instability is progged to be quite modest (MLCAPE <1000 J/kg), but still think we`ll get some thunderstorms across our far western counties. The highest PoPs are in SE VA and especially NE NC from the late morning hours into the afternoon with the low passing to the S. Cannot rule out of some thunderstorms down here as well though the more robust convection is expected S of the Albemarle Sound eastward to the Outer Banks. Elsewhere across the I-95 corridor into the Northern Neck and Eastern Shore, a relative minima in precip coverage is expected with PoPs 20% or less. The front should then push through Monday and a few showers or storms could redevelop across eastern portions of the area. However, coverage looks quite sparse with decent dry air advection on the heels on the front. A degree or two warmer for high temps Sunday with lower 80s across SE VA/NE NC (due to higher precip/cloud coverage) and mid 80s elsewhere. Monday looks to be warmest day of the forecast period as temps surge in the upper 80s across SE VA and NE NC with lower-mid 80s to the N and NW. Forecast overnight lows are in the mid-upper 60s Sunday night and upper 50s-lower 60s Monday night (as cooler/drier air filters in behind the front). && .LONG TERM /TUESDAY THROUGH FRIDAY/... As of 245 AM EDT Saturday... Key Message: - Very nice next week with lots of sun and comfortable temperatures and humidity. All signs point to ending August on an autumnal, pumpkin spice- flavored, note. Strong sfc high pressure from south-central Canada builds toward Great Lakes and eventually the eastern CONUS mid-late week. There is also good agreement across the global models that a deep trough dips in overhead and remains in place through the rest of the week. Several shortwaves rotating through should also provide reinforcing shots of cooler and drier air. Dew points as low as the upper 40s are also expected by mid-week. The continental origin of the airmass and strong subsidence from the high should keep a nearly 0% chance of rain through the end of the week. Highs through the week are forecasted to be several degrees below normal and in the mid 70s to around 80 F. Lows should generally be in the mid 50s inland and low 60s in the east, but these could certainly trend cooler as NBM tends to run high in these patterns. In fact, the currently available statistical model guidance shows some potential for upper 40s across the Piedmont Tuesday and Wednesday nights. && .AVIATION /10Z SATURDAY THROUGH WEDNESDAY/... As of 545 AM EDT Saturday... VFR conditions prevail through the 12z TAF period. Light winds this morning increase to 5-10 kt out of the E/ESE this afternoon and evening. CU develops later this morning and afternoon, 245 especially across SE VA and W of RIC. There should also be an increase in high clouds later today, becoming BKN-OVC by this evening. A weak area of low pressure will lift N along the NC coast early Sunday. Lowering CIGs are possible at ECG after 09z Sunday. Outlook: Dry and VFR conditions prevail through Saturday night. A chc of showers/tstms returns Sunday and Monday ahead of and along a cold front, but widespread flight restrictions are not expected. MVFR is possible, however, in NE NC Sunday morning as the weak low approaches. Mainly VFR Monday as a cold front pushes through, with a dry airmass and VFR Tuesday through the end of next week. && .MARINE... As of 245 AM EDT Saturday... - Small Craft Advisories remain in effect over the coastal waters through late tonight/early Sunday due to hazardous seas. - Otherwise, high pressure builds over the waters today, before sliding offshore later today into Sunday. Look for diminishing E-SE winds today into Sunday, before winds turn around to the S-SW tomorrow night into Monday, as weak low pressure lifts across the waters. - Cool high pressure builds over the waters late Monday night through midweek. Latest analysis shows the post-tropical remnants of Erin southeast of Newfoundland, heading farther out into the north Atlantic. Locally, winds continue to diminish to 10-15 kt or less over the lower mid-Atlantic, with winds veering around to the E-SE as high pressure builds in overhead the from NW. Seas have been slow to come down as expected given the ongoing E-NE long period swell (10-12 seconds) with seas lingering in the 4-6 ft range nearshore, 5-7 ft just offshore. Waves in the bay have subsided to 1-2 ft, up to around 3 ft in the mouth of the bay, where the SCA has been allowed to expire early this morning. High pressure slides overhead today before moving offshore this afternoon and tonight. E-SE winds average ~10kt today, diminishing under 10 kt tonight. Seas look to finally drop below 5ft on Sunday over the northern and central waters, allowing SCA to finally be lowered...though southern waters may take a bit longer into Sunday night, and SCA has been extended through SUnday afternoon over the coastal waters south of Cape Charles. Benign marine conditions look to prevail into early next week, as another weak cold front drops across the area Monday morning. A deepening sfc low along that front scoots by to our south/southeast offshore, which turns winds around to the SSW Sunday night into Monday, turning NW and increasing slightly to 10-15kt later Monday into Monday night. A second, stronger front then crosses the waters Monday night into Tuesday. Wind probs for gusts ~20 kt have increased to 30-50% in the bay, and thus a brief period of marginal SCA winds will be possible around and just before sunrise Tuesday morning, as cooler, drier air builds south across the local waters. Rip Currents: With lingering long-period (10-14s) swells and nearshore breaking waves of 6+ feet, dangerous swimming conditions and high risk of rip currents is expected through the weekend. && .TIDES/COASTAL FLOODING... As of 250 AM EDT Saturday... Tidal anomalies continue to gradually lower in the lower bay, remaining steady over the bay side of the Lower Eastern Shore (MD) and the tidal Potomac through late tonight/early Sunday. Farther south, easing anomalies should allow for improving tides over the next few cycles, though some minor flooding remains possible over the tidal Rappahannock River and the VA Lower Eastern Shore, and a Coastal Flood Advisory has been maintained today. Farther south, anomalies have dipped enough that only nuisance/near-minor tidal flooding is expected today. However, given the marginal tide levels have maintained a Coastal Flood Statement for the tidal York and James Rivers through this evening`s tide cycle.. Beyond tonight, lingering minor to locally moderate coastal flooding is possible over the lower MD Eastern Shore tomorrow into tomorrow night/early Monday, before tides finally ease a bit into the day Monday as winds finally switch offshore. && .AKQ WATCHES/WARNINGS/ADVISORIES...
