668 FXUS61 KAKQ 021903 AFDAKQ AREA FORECAST DISCUSSION National Weather Service Wakefield VA 303 PM EDT Sat Aug 2 2025 .SYNOPSIS... Cooler temperatures expected behind a seasonally strong cold front. Dry weather with lower humidity and cooler than normal temperatures are expected for the upcoming weekend and into early next week. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... As of 225 PM EDT Saturday... Key Messages: - Mostly cloudy, cooler, and drier this afternoon. - Lows range from the upper 50s in the piedmont to around 70 immediately near the coast tonight. Mid-day sfc analysis indicates a large area of high pressure (1028- 130mb) building into the FA from the NW and yesterday`s cold front well south of the area. Aloft, a trough axis swings towards the Northeast and Mid-Atlantic with more zonal flow to the south. Lower level moisture lingers over the area, leading to continued broken cloud cover. Additionally, there is a low-end chance for a few sprinkles/light rain showers over far southern VA and northern NC. The pressure gradient between the front to the south and building high pressure is enough to support gusty onshore winds at the coast. The cloudy skies, breezy conditions, and temps only in the upper 70s makes it feel a lot more like early to mid fall rather than the second day of August (you can practically smell the pumpkin spice in the air). As we head into the evening, the cloud cover should start to scatter out. By late tonight, most of the area should be under clear skies with a few clouds lingering in the SE. While the breeze will continue overnight immediately near the coast, winds inland will be near-calm. Lows tonight will be in the mid-upper 50s W of I-95, low 60s along and E of I-95, and around 70 immediately near the shore. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/... As of 225 PM EDT Saturday... Key Messages: - Cooler temperatures continues from Canadian high pressure. - Mostly dry through early week as high pressure dominates. The below normal temps and lower humidity continue Sun as the cool high pressure ridges down the coast behind low pressure deepening well offshore. Highs will be in the low 80s under partly sunny skies. Breezy onshore winds with gusts ~20-25mph at the coast are expected again during the day Sunday. Lows Sunday night will be in the upper 50s W of I-95 and ranging through the 60s E of I-95. Not terribly different for Monday, though a couple of degrees warmer with highs in the mid 80s. The developing low pressure will stay well offshore as it progresses NE on Monday, but cannot totally rule out an isolated shower at the coast Monday afternoon. Lows Monday night will be in the low 60s inland and upper 60s/around 70 closer to the shore. && .LONG TERM /TUESDAY THROUGH SATURDAY/... As of 225 PM EDT Saturday... Key Messages: - Cooler below average to seasonable temperatures outlooked through late week. - Mostly dry conditions with returning moisture and increasing rain chances by mid week. The strong high pressure will begin to slide offshore Tuesday which will allow for a more modified airmass. Increasing moisture is expected by Tuesday as an upper trough that will extend from the Great Lakes through the SE US brings in deeper atmospheric moisture to the region from the Gulf. The GFS continues to suggest that another weak area of low pressure could develop off the Carolina coast along the stalled frontal boundary during this time period, but this feature does not appear in the other 12z global models. This could enhance the moisture moving into our area if it manifests. As the trough moves over the area, rain chances return mid week. Temperatures will remain at or below the normal for this time of year with highs in the lower to mid 80s and lows in the mid to upper 60s. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... As of 125 PM EDT Saturday... VFR prevails for the terminals during the 18z/02 TAF period as high pressure builds in from the NW. Still have a mid level BKN cloud deck with CIGs at 045-075kft. Still expecting clouds to scatter out heading into the evening and overnight. NE winds will continue to be gusty through late this afternoon, particularly at PHF/ORF/ECG where 20-25kt gusts are forecast. Lighter winds overnight, especially inland. Becoming breezy again mid morning tomorrow. Outlook: Predominantly VFR prevails through early next week as drier air filters in behind the cold front, but NE winds remain elevated along the coast into Sunday. && .MARINE... As of 300 PM EDT Saturday... - Small Craft Advisories are in effect all areas today, and for much of the region through early Monday. - High Risk for Rip Currents in effect all beaches today, with a High Surf Advisory in effect for the Atlantic coast of Currituck NC. Strong nearly 1030mb high pressure is centered over the Great Lakes this aftn, with low pressure centered E of the SC coast. A strong NE wind continues, mainly 15-20kt with gusts to 25kt, but locally 20-25kt with gusts to 30kt S of Cape Henry. Seas range from 5-6ft N to 7-9ft S. Waves in the Ches. Bay are mainly 3-4ft for the mid/upper Bay, and 4-5ft for the lower Bay and mouth of the Bay. The surface high slowly moves east this later this aftn into tonight, with the pressure gradient expected to weaken a bit, especially over northern portions of the marine area late this aftn and evening. Winds will likely diminish to 10-15 kt over the upper Bay and upper rivers, while remaining 15-20kt elsewhere. However, a late evening overnight increase to 15-20kt is likely over the mid/upper Bay tonight. SCAs continue through Sunday night/Monday morning for the lower Bay, lower James, Currituck Sound, and coastal waters (NC coastal waters have been extended through late Monday aftn), but may be able to be dropped late today/tonight at least for the upper rivers. The SCAs for the ocean will probably need further extensions in time for seas at or above 5 ft, at least from the VA/NC border through Parramore Is. The general pattern keeps onshore flow in place through the week, with strong/anomalous high pressure (>1030 mb) becoming centered over eastern Canada and New England Tuesday-Thursday. Expect at least elevated E to NE winds and possibly SCAs for much of the area. A High Rip Current risk remains in effect for all beaches today, with 6-8ft seas south, and 4-6 ft seas north (where more of a strong longshore current prevails). A high Rip risk will continue Sunday over the south, and likely a High risk for the northern beaches as well. High south and moderate north will likely linger into early next week. && .TIDES/COASTAL FLOODING... As of 300 PM EDT Saturday... Tidal anomalies this aftn average around 1.5-2ft above normal over the lower Bay, and ~1.5ft above normal across the northern Neck along the western shore of the Bay and southern shore of the Potomac. This is due to the elevated NE wind, elevated seas, and 2 successive flood tides at the mouth of the bay (with no ebbing in between). A brief ebb tide was observed late this morning, but has quickly shifted to a flood tide. Therefore, expect anomalies to continue to rise over the next 12-36 hours as NE winds persist and seas build a bit more across the SE VA/NE NC coastal waters. Coastal Flood Advisories and Statements for expected minor tidal flooding during the high tide later this aftn and evening/overnight remain in effect. The highest chc of minor flooding is from Lewisetta to Tappahannock along the tidal Potomac/Rappahannock Rivers as well as the bay side of the MD Eastern Shore, with nuisance to minor tidal flooding over the lower Bay and tidal James River. It is rare to see more than 3 successive flood tides without an ebbing at the mouth of the Bay so with this in mind, moderate flooding is unlikely and would anticipate departures to peak with the high tide later today/tonight. Water levels should fall a bit later this weekend as NE winds/seas subside a bit, though nuisance to low end minor flooding will be possible again Sunday aftn/evening with the higher of the two astronomical tides. A High Surf Advisory remains in effect through this evening for Outer Banks Currituck for nearshore waves around 8ft. && .AKQ WATCHES/WARNINGS/ADVISORIES...
