224 FXUS61 KAKQ 080144 AFDAKQ AREA FORECAST DISCUSSION National Weather Service Wakefield VA 944 PM EDT Mon Jul 7 2025 .SYNOPSIS... The post-tropical remnants of Chantal lift north of the area through tonight, with showers and storms tapering off this evening over coastal VA and Maryland. Behind the storm, mild, muggy conditions are expected tonight, with very warm and humid conditions are expected for the latter half of next week. A rather stagnant, unsettled pattern takes hold for the rest of the week, with mainly hit or miss type afternoon and evening showers and storms possible each day. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... As of 945 PM EDT Monday... Key Message: - Drying out, with warm and muggy conditions overnight. Any lingering showers and thunderstorms from earlier this evening have largely come to an end with the loss of daytime heating. Decreasing clouds, warm and muggy overnight with lows in the upper 60s to mid 70s. Some patchy fog possible toward morning. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/... As of 250 PM EDT Monday... Key Message: - A weakening cold front approaches the area through midweek, then stalls north of the area. This front will be the focus for afternoon and evening storms tomorrow and through late week. - A Slight Risk for severe storms is now in place for much of the northern half of our area, including central and eastern VA, Richmond Metro and the bay side of the MD eastern shore. A Marginal Risk for severe storms is in place for the rest of the area. - A Slight Risk for Heavy Rainfall is also in place for the northern half of the area, with a Marginal Risk farther SSE. - A Heat Advisory is in effect for most of the area for Tuesday. More typical July weather is on the way for the midweek period, with the hot and moderately humid airmass returning, along with daily thunderstorm chances. An upper trough slides across the Great Lakes tomorrow, shunting a weakening sfc front toward the region from the northwest. As is typical for this time of year, the boundary is likely to become stalled just NNW of the FA tomorrow evening, with that front then meandering in place for the rest of the week. Heat Headlines: Highs tomorrow will be in the low-mid 90s, which in tandem with dewpoints in the low to mid 70s bring heat indices approaching 105 for much of the area (primarily along and E of I-95). Further complicating matters, we expect late afternoon and evening scattered storms across the area with highest coverage in the NW by evening, shifting over to the Eastern Shore later in the evening. That said, late timing allows a full to nearly full heating day across the area, with most if not the entire area reaching 103-108 deg heat indices, not unusual for early July, but nonetheless within Heat Advisory criteria. For that reason, a Heat Advisory has been issued for most of the area, with the exception of the far NW that may mix a little bit better and could see mid afternoon convection. Severe/Heavy Rain threat: To that end, SPC has upgraded much of the northern half of the area (except coastal MD/VA eastern shore E of US-13) to a convective Slight Risk for severe, with a Marginal Risk for the rest of the area, with damaging wind gusts as the main threat. However, confidence is low since the flow aloft looks rather week and storms will be relying on large amounts of instability and water-loaded downdrafts. A SlightPTC Risk ERO will also be in place across the northern half of the area nearer to the stalling front, with a Marginal Risk ERO for south central VA and SE VA/NE NC. Again with slow steering flow, instances of flash flooding remain a concern. Will not extend or re-issue Flood Watches at this time for tomorrow or Wednesday, but additional targeted flood headlines may well be necessary tomorrow and as the week wears on given the rather stagnant/persistent warm/muggy setup, with numerous rounds of sct convection and heavy rainfall likely. Wednesday: Wednesday looks largely the same, except a couple of degrees cooler with highs in the low 90s due to earlier and more widespread storm coverage, with the stalled front again serving as the focus for afternoon and evening convection. Another Slight Risk north/Marginal south for heavy rainfall on Wednesday, with a Marginal severe risk area wide. Heavy rain and isolated flooding will again be possible with gusty winds the main severe threat. && .LONG TERM /THURSDAY THROUGH MONDAY/... As of 250 PM EDT Monday... Key Messages: - Staying seasonably very warm and humid through the end of the week with mainly afternoon/evening storm chances persisting. The typically warm and unsettled pattern continues to end the week and into the weekend. Highs each day will be around norms for this time of year i.e. upper 80s/around 90. We will continue to see diurnal showers and thunderstorms each day through Sun. Thursday looks like the highest coverage day of the period as of now owing to potential development of weak low pressure near the FA/along the front. Will say that exact details are difficult to latch on to at this point since a lot of it will be conditional upon where the meandering front goes and when, plus the weaker flow aloft. && .AVIATION /02Z TUESDAY THROUGH SATURDAY/... As of 725 PM EDT Monday... There are a few remaining isolated thunderstorms this evening, but these are expected to stay away from the TAF sites. Otherwise, mainly dry and VFR conditions through tonight and into the first half of Tuesday. Potential for some ground fog late tonight at SBY/PHF, though probabilities are low enough to hold out of the terminal forecast for now. Scattered showers and thunderstorms develop late Tuesday afternoon into Tuesday evening, with the best coverage across the northwestern half of the area. Introduced a PROB30 at RIC and SBY late in the period due to the thunderstorm potential, activity likely stays more isolated further south and east. Outlook: A typical very warm and humid midweek period across area terminals through Friday. Late day and evening scattered showers/tstms are likely, along with some early morning ground fog/stratus. && .MARINE... As of 310 PM EDT Monday... Key Messages: - SCAs continue for northern coastal waters until 1 AM tonight to account for elevated seas. - The SCAs have been extended until tomorrow morning for Lower Chesapeake Bay. - A Moderate Rip Current Risk remains in place for all beaches today and Tuesday. - Sub-SCA conditions prevail Tuesday-Friday with daily thunderstorm chances. Afternoon satellite imagery and surface observations so the center of Post Tropical Cyclone Chantal located over the DELMARVA peninsula. Winds this afternoon are starting to shift out of the NW across the bay behind PTC Chantal. Winds still remain between 10 to 15 kt with gusts upwards of 20. Some elevated sites are reporting slightly higher wind gusts near 25 kt. Winds across the ocean are the same speed at the bay however, they remain out of the S to SW ahead of PTC Chantal. Waves this afternoon are between 2 to 3 ft across the bay and 4 to 5 ft across the ocean. Late this afternoon and early evening, winds across the area are expected to lower below SCA for the bay, lower James, and Currituck Sound. The SCA is allowed to drop for the lower James and Currituck Sound at 4pm. However, the SCA will continue for the mouth and lower bay. This is due to a secondary surge of SCA winds behind PTC Chantal as she exits the area. Will note, there will be a dull period between 0-6z for Small Crafts. During this dull period winds will shift back out of the SW between 10 to 15kt across all waters. Then between 6 to 12z Tuesday Winds will increase to 15kt sustained across the mouth and lower bay and oceans with gusts upwards of 20 kt. For the oceans, the SCA for the far southern coastal zone is expected to drop ~7pm and seas will diminish below 5ft. While from the VA/NC boarder up to Ocean City those SCA will drop ~1am Tuesday as 5ft seas should diminish. For tomorrow, winds will be out of the S-SW between 10 TO 15 kt across the bay and 15 to 20 kt across the ocean. The daily chances of showers and thunderstorms do increase for tomorrow afternoon. These thunderstorms could potentially bring gusty wind that could bring elevated winds and seas across the local waters. The stronger thunderstorms will be handled with SMWs. Rip Currents: A Moderate Risk of rip currents continues across all beaches Tuesday. This is due to ~3 ft nearshore waves. && .AKQ WATCHES/WARNINGS/ADVISORIES...
