AREA FORECAST DISCUSSION National Weather Service Wakefield VA 1028 AM EDT Tue Sep 28 2021

SYNOPSIS. High pressure will slide farther off the coast during today. A cold front will cross the local area late today into tonight. High pressure returns for Wednesday into the upcoming weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 1025 AM EDT Tuesday .

Late this morning, sfc high pressure was centered off the Mid Atlc and SE coasts. While a cold front was pushing through nrn OH and PA. The high will slide farther into the Atlc today into this evening. A weak sfc trough develops this aftn in advance of the cold front approaching from the NNW. Low level heating and cooling aloft (as trough aloft progresses into the region) will steepen lapse rates this aftn, resulting in modest instability. Best shear aloft is shown to be over N and NE areas of the FA later this aftn into this evening. Potentially favorable overlap of instability and shear may support isolated to sctd storms, mainly across nrn and NE areas from late this aftn into this evening. Some concern over dew point recovery (into the lower to mid 60s) this aftn, due to SW low level flow (which may limit convective potential). SPC has a slight risk over far nrn/NE tier of FA, with marginal risk down to near the I-64 corridor. Otherwise, sunny then becoming partly cloudy this aftn with SW winds 5-15 mph. Highs will range through the 80s.

SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/. As of 220 AM EDT Tuesday .

Mainly evening convection, esply E of I-95 to the coast, wanes/diminishes after midnight. Winds become N and gusty (at the coast) after midnight, as drier/cooler air spreads into the local area. Lows from the m50s-l60s.

High pressure will build down into the area from the north for Wed through Thu. Pleasant wx expected, with highs ranging through the 70s both days Lows Wed night will range u40s-m50s inland. m-u50s along coastal SE VA-NE NC.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. As of 250 AM EDT Tuesday .

Continuing to run w/ the 00Z/28 ECMWF solution for the extended period. Most of the extended period will remain dry, as sfc high pressure builds down over the region, then slides out to sea. Low pressure over the OH Valley and a frontal boundary to our north, could provide a chance for showers Mon aftn/night.

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

AVIATION /14Z TUESDAY THROUGH SATURDAY/. As of 635 AM EDT Tuesday .

A cold front approaches from the NW this afternoon then crosses the FA w/ psbl ISOLD/SCT convection through this evening. VFR conditions . except for flight restrictions (mainly VSBY) and gusty winds w/ any SHRAs/tstms (mainly from 20Z/28-04Z/29). WSW winds 5-15 kt. Winds become NNW after midnight. VFR conditions expected Wed through Fri as hi pres builds back into the mid- Atlantic region.

MARINE. As of 330 AM EDT Tuesday .

Early this morning, high pressure is centered south of the local waters. Meanwhile, a cold front is approaching the waters from the NW. Winds remain breezy out of the SW, especially for the northern Bay/coastal waters, with wind speeds of 15 to 20 knots and gusts to 25 knots. Seas range from 3 to 5 feet for the northern coastal waters and 2 to 3 feet for the southern waters. Waves in the Bay are generally around 2 to 3 feet.

Winds gradually diminish through this morning into this afternoon as the cold front approaches. The front is expected to cross the waters tonight into early Wednesday morning with winds becoming N to NW and increasing to 15 to 20 knots in its wake. Another round of Small Craft Advisories will likely be needed for the Chesapeake Bay from around 09z Wed through 15z, with local wind probabilities showing a 60 to 70% chance of SCA conditions during this period as drier/cooler air moves across the warmer waters of the Bay. Winds diminish below SCA criteria by mid to late morning Wednesday, but will remain around 15 knots through much of the day. High pressure builds from the NW later Wednesday through the end of the week, allowing for generally sub-SCA conditions Wednesday afternoon through Friday.

Uncertainty remains this weekend regarding the extent of the impact of increased swells from Hurricane Sam which will pass well offshore. SCAs for seas may be needed. A period of increased rip current risk will also be possible this weekend due to the swell. The rip risk will be low today and moderate for the southern beaches on Wed.

AKQ WATCHES/WARNINGS/ADVISORIES. MD . None. NC . None. VA . None. MARINE . Small Craft Advisory from 10 PM this evening to noon EDT Wednesday for ANZ630>632-634-638.
