AREA FORECAST DISCUSSION National Weather Service Wakefield VA 746 PM EDT Thu Jul 29 2021

SYNOPSIS. Low pressure will track by north of the local area tonight to be followed by its trailing cold front during Fri. The front stalls across the Carolinas by Saturday. Low pressure moves east along the front Sunday.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. As of 745 PM EDT Thursday .

Isolated supercell continues to drop SSE east of the Richmond metro. This long-lived cell has a history of wind damage and has shown impressive hail signatures on radar. If the cell can manage to hold together it could impact the Williamsburg area and areas to the south and southeast. The environment across the region remains supportive of strong to severe storms but will little forcing to trigger any new convection. Severe Thunderstorm Watch 402 is in effect until 9pm.

Additional showers with a chance of thunder could impact the NE portion of the area including the MD eastern shore and Northern Neck after midnight tonight. Lows tonight in the low 70s N to the mid and upper 70s S.

SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/. As of 310 PM EDT Thursday .

The cold front progresses into/through srn/SE portions of the FA Fri Right now. SPC has MRGL along/S of the Albemarle Sound . still will carry 20-30% far srn/SE VA across NE NC before the frontal passage. Will be another hot/humid day (heat indices topping out around 100F one last day in this stretch) across srn/SE VA and NE NC (pre-frontal passage) while drying/lowering dew points occurs over central/nrn portions. Highs in the u80s-l90s.

Any lingering SHRAs/tstms Fri evening likely to diminish/end early. Period of NNE winds (gusty at the coast) and cold/dry air advection Fri night into Sat ends the recent period of high humidity heading into the weekend. Low Fri night in the l60s N to around 70F far SE.

The front stalls across the Carolinas by Sat. Expecting mostly sunny conditions N and partly sunny S and very comfy for the last day of July Highs in the l80s. u70s right along the coast/beaches.

This time of year . hard to keep the dry/cooler wx here. Hi pres shifts off the SE coast of New England Sat night leading to a quick return of moisture from the SSW. A series of lo pres systems forecast to moves along the stalled front (across NC). Increasing PoPs to 50-70% (mainly SHRAs) for late Sat night into Sun afternoon along w/ widespread clouds. Lows Sat night mainly in the m-u60s. Highs Sun in the 70s to l80s.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. As of 100 PM EDT Thursday .

Unsettled wx conditions expected early/mid next week as trough aloft amplifies through Great Lakes and OH/TN Valleys. Initially a frontal boundary is forecast to push just offshore Sun night/Mon then due to the trough digging in to the W of the FA . the front would likely back WNW into the local area through mid week. The overall pattern setting up is fairly typical for mid Summer (and fits an MJO forecast of a transition from phase 6 to phases 8 and 1 - favoring BLO normal temps and near-ABV normal pcpn) and usually leads to a few/several days of high potential for SHRAs/tstms and psbl heavy rainfall. Have capped PoPs at 50% through the period.

Nighttime lows through the period mainly from the m60s to around 70F. Highs Mon 80-85F. Highs Tue in the l80s. Highs Wed and Thu in the l-m80s.

AVIATION /00Z FRIDAY THROUGH TUESDAY/. As of 745 PM EDT Thursday .

Will show prevailing VFR at all sites through the 00z TAF period. One exception could be PHF where a long-lived supercell continues to drop SSE toward the terminal. Current trajectory would keep the core of the cell a bit to the west of PHF. Will include VCTS at PHF and VCSH at ORF for lingering precip this evening. Elsewhere, mostly dry tonight with SCT/BKN mid level cloud debris. A few showers or storms could impact SBY after midnight so have included VCSH for this period. SW winds 10-15 kt become NW 5-10 by mid morning Friday behind a weak cold front. Additional storms are possible at ECG once heating gets underway on Friday. Confidence in coverage and placement is too low to include in the forecast at this time.

Generally VFR Fri night/Sat though NNE winds become gusty near the coast. Lo pres tracking across NC Sun may result in IFR/MVFR conditions and psbl SHRAs.

MARINE. As of 320 PM EDT Thursday .

A cold front moves over the local waters late tonight into Friday. Ahead of the front, winds are S/SW 10-15 kt, becoming SW 15-20 kt late this evening into tonight. A Small Craft Advisory remains in effect for the Chesapeake Bay, Lower James, and Currituck Sound from 8 PM through most of the night. As the cold front moves through late tonight through Fri morning, winds shift to NW/N 10-15 kt, remaining N 10-15 kt through Fri night. Winds may approach SCA criteria with the CAA surge late Fri night into early Sat, but for now, expect winds to remain around 15 kt. Winds switch from NE 5-10 kt to SE Sat into Sat night, remaining SE 10-15 kt through Sun. Another cold front comes through Sun night with winds shifting back to N Mon.

Waves of 1-2 ft and seas of 2-3 ft build to 2-3 ft and 3-4 ft respectively overnight before subsiding back to 1-2 ft and 2-3 ft by Fri afternoon through early next week. Seas may approach or briefly touch 5 ft tonight, but confidence is too low to issue a SCA at this time.

Moderate rips expected Sat.
