AREA FORECAST DISCUSSION National Weather Service Wakefield VA 833 PM EDT Tue Sep 28 2021

SYNOPSIS. A cold front will cross the local area through early Wednesday morning. High pressure will build down into the mid Atlantic Wednesday afternoon, and will settle across the region from Wednesday night through Saturday.

NEAR TERM /UNTIL 8 AM WEDNESDAY MORNING/. As of 800 PM EDT Tuesday .

The latest analysis indicates a WNW flow aloft with a weak sfc trough currently over the region. The cold front is still off to the N of the local area, currently pushing just S of the Mason- Dixon Line. Mid level (H7-H5) lapse rates have been fairly impressive this evening >7C/km and this has enabled some stronger storms to our NW (primarily with large hail) to hold together into central VA over the past few hrs. The severe threat is fairly limited at this point but some stronger cores still may affect the region over the next few hrs. PoPs are highest across central and east central VA, will maintain at least 20% PoPs for most of VA/MD since the front still has to push through over the next few hrs and some additional showers/tstms could redevelop along the front. Will keep it dry across NE NC and the southern piedmont zones. Added patchy fog to portions of the northern piedmont where the more widespread showers/tstms occurred earlier. Lows overnight will range from the mid-upper 50s N to the mid 60s S.

SHORT TERM /8 AM WEDNESDAY MORNING THROUGH FRIDAY/. As of 355 PM EDT Tuesday .

High pressure will build down into and over the region for Wed through Fri. After some scattered clouds Wed morning, dry/pleasant wx and mostly sunny/clear conditions will prevail, with highs ranging through the 70s Wed and Thu, and in the lower to mid 70s Fri. Lows will range from the upper 40s to upper 50s Wed night and Thu night.

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/. As of 355 PM EDT Tuesday .

Continuing to run with the 12Z/28 ECMWF solution for the extended period. High pressure will maintain dry wx for Fri night into at least Sun morning, as it will be over the area then slides off the coast. Frontal boundaries approaching from the west and north Sun night through Tue, will provide chances for showers and possibly a tstm.

Lows will range from the upper 40s to the upper 50s Fri night, in the mid 50s to lower 60s Sat night, in the upper 50s to mid 60s Sun night and Mon night. Highs will range through the 70s to around 80 through the period.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/. As of 800 PM EDT Tuesday .

Mainly VFR conditions prevail this evening, with flight restrictions confined to northern portions of the CWA where scattered showers/tstms are ongoing. Brief gusty winds will be possible in any shower/tstms along with reduced VSBYs. Have included a TEMPO group for MVFR VSBYs at RIC, but nothing more than "VCSH" wording at the other terminals where the chances are lower. The cold front crosses the region from N to S between 03-09Z, and will be S of the region before sunrise. Northerly winds on Wed will be around 10kt inland and 10-15kt near the coast. A few hrs worth of MVFR CIGs will be possible through late morning with mostly sunny skies thereafter.

Outlook . VFR conditions will prevail Wed aftn through Fri, as high pressure builds down into and over the Mid Atlc region.

MARINE. As of 320 PM EDT Tuesday .

Latest analysis reveals ~1016 mb sfc high pressure offshore of the southeast coast, extending SW across the eastern Gulf coast. To the north-northwest, Sfc cold front is dropping across eastern New England, extending SW to the central Appalachians at 19z. W-SW winds ~10 kt are common across the waters this afternoon, with a few gusts to around 15 kt, mainly over elevated terminals in the northern and middle Bay. Seas generally 2 to 3 feet over local waters with some 3-4 foot seas still lingering over offshore waters north of Parramore Island. Waves in the Bay are generally 1-2 feet.

Previously-referenced cold front drops across the waters late tonight into early Wednesday morning. A few SMWs possible this evening through ~ midnight with isolated-scattered convection along the front. Thereafter, a post-frontal surge of 15-20 kt is expected after midnight into early Wed morning. Have hoisted SCA over the Ches Bay and lower James River with this package, in effect from late tonight through noon Wed. Winds then gradually diminish below SCA criteria from late Wed morning into the afternoon. Winds should linger ~15 kt for much of the afternoon with steady surge of cooler, drier air dropping south across still aoa low to mid 70s local waters. High pressure builds across the region from the NW tomorrow night through late week, yielding more benign boating conditions for the late week period. Rip Risk will be moderate all beaches tomorrow and over northern beaches for Thursday.

Looking ahead, winds will remain sub-SCA with high pressure lingering over the region into the weekend. However, some longer period swell from distant Hurricane Sam well out in the Atlantic looks to arrive, impacting local waters by later in the upcoming weekend. A round of SCAs, mainly for hazardous seas, are possible over the Atlantic coastal waters Sat-Sun. Another period of increased rip current risk will also be possible this weekend due to the arriving longer period swell.
