AREA FORECAST DISCUSSION National Weather Service Wakefield VA 1008 PM EDT Sun Sep 19 2021

SYNOPSIS. High pressure builds across the area tonight, then slides off the coast through Wednesday. A strong cold front crosses the area Thursday. Canadian high pressure builds in for next weekend.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. As of 1005 PM EDT Sunday .

Backdoor cold front continues to make slow progress southwestward across the region tonight. The boundary will gradually washout overnight but the surface high will continue to build down the eastern seaboard. But with the slower movement, the push of cooler and drier air has been slower than models have forecast. As a result, have raised overnight lows over the SE VA and NE NC for tonight into the upper 60s to near 70 degrees. Otherwise expect clear sky and dry weather.

SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/. As of 250 PM EDT Sunday .

High pres slides off the coast to our north Mon into Tue. Models cont to show moisture slowly increasing across the west Tue afternoon due to a developing se flow. Will carry low chc PoPs Tue aftrn, otw dry. Highs Mon upr 70s-lwr 80s. Lows Mon nite in the 60s to near 70 se. Highs Tue upr 70s-lwr 80s.

The upslope moisture will be greatest across the west Tue nite so will carry low chc PoPs mainly along and west of I95. Otw, pt to mstly cldy. Lows mid-upr 60s xcept nr 70s se.

Moisture continues to increase Wed ahead of the apprchg upr lvl trof. Best support for PoPs will be across the west during the aftrn. Have kept chc PoPs for now over most areas Wed xcept low end likely across the wrn most zones. Highs upr 70s west to low- mid 80s along the coast.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. As of 110 PM EDT Sunday .

GFS trending closer to a slower (ECMWF) solution for later this week. Data shows an upper low moving across the Ohio Valley Wed nite and nern states Thurs with the trailing cold frontal passage across the local area Thurs aftrn and eve. Ahead of it, onshore flow continues the threat for sct- nmrs overrunning shwrs Wed nite and Thurs morning before a significant slug of moisture moves across the area Thurs aftrn with the fropa, pushing off the coast Thurs eve.

Given the increasing confidence, went ahead and bumped up PoPs Wed nite and Thurs to high chc/low end likelys for now. Any thunder limited to the actual fropa Thurs. Lows Wed nite in the 60s. Highs Thurs in the 70s to near 80 se. Shwrs end west-east Thurs nite. Cooler with lows 50-55 west, upr 50s-lwr 60s east.

Canadian high pres builds in for the upcoming weekend. Dry, cooler each day. Highs Fri in the 70s. Lows from the upr 40s nw to lwr 60s se. Highs Sat 75-80. Lows in the 50s to lwr 60s se. Highs Sun mid 70s-lwr 80s.

AVIATION /02Z MONDAY THROUGH FRIDAY/. As of 800 PM EDT Sunday .

A back door cold front continues to push south and west across the Mid-Atlantic states this evening with the front stretching from near ECG to FVX. ALong the front, see some mvfr level stratus that should last a couple of hours before the drier air arrives and vfr conditions return. For the remainder of the area, the drier air is already beginning to arrive and the sky is mostly cloud free and should remain that way over night. High pressure will dominate the weather on Monday with drier air with a light nw as the high builds southward along the Eastern Seaboard. Overall expect mainly vfr conditions through the taf period outside of a short period of mvfr level ceilings at ECG through 2z-4z.

Outlook: VFR conditions then persist Mon thru Tue night, as high pres dominates. Moisture slowly increases by mid week ahead of a strong cold front, which crosses the area Thursday.

MARINE. As of 400 PM EDT Sunday .

A high threat of rip currents is in effect through 8 pm this evening for the southern beaches (VA Beach/Currituck). A moderate risk is in effect for the northern beaches. Late this aftn, sfc high pressure was centered over Lake Ontario and extending down into the Mid Atlc region. Winds were NE 5-15 kt over the waters, with waves 1-2 ft and seas 3-4 ft.

The center of the sfc high will slide east across New England then off the coast tonight into Tue morning. NE then E winds 5-15 kt tonight into Mon morning, then generally E 10-15 kt Mon aftn into Mon evening. Winds will be E 5-15 kt Mon night into Tue, then SE Tue night through Wed, with winds increasing to around 15 kt Wed aftn, as the high moves into the nrn Atlc and cold front starts to approach from the WNW. Waves will be 1-3 ft and seas 3-4 ft into Wed morning, then waves 2-3 ft and seas 3-5 ft by late Wed.

The cold front approaches the waters from the WNW late Wed into Wed night, before crossing the waters Thu evening into Thu night. S winds at least 10-15 kt Wed night and Thu, then becoming NW or N 10-15 kt Thu night.
