AREA FORECAST DISCUSSION National Weather Service Wakefield VA 942 AM EDT Sun Sep 19 2021

SYNOPSIS. A weak cold front drops across the region later today. High pressure builds across the area today and tonight, before sliding offshore Monday through midweek. A strong cold front crosses the area Thursday into Thursday night, bringing markedly cooler and drier air to the region for late this week into next weekend.

NEAR TERM /THROUGH TONIGHT/. As of 935 AM EDT Sunday .

Another warm late summer day ahead. Mostly sunny with a NNE wind aob 10 kts. Can't rule out a stray shwr across the s-sw after 18Z. Highs in the 80s, coolest along the coast.

PVS DSCN: Any lingering showers push SSW into north central/central NC this evening, with a gradually clearing sky expected. Could see a recurrence of late night stratus/fog late tonight, mainly in our SW piedmont into NE NC. Otherwise, mild with lows again in the mid 60s to the lower 70s.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/. As of 350 AM EDT Sunday .

High pressure slides offshore of the northeast/northern Mid- Atlantic coast late Monday into Tuesday, signaling another modest warmup Mon/Tue. Models show a slow increase in moisture Tue aftn as the flow becomes onshore. Minimal instability through the period, as mid/upper ridging lifts over the eastern seaboard, so will not carry any thunder wording. However, did carry low chc PoPs for scattered afternoon and evening showers mainly along/west of I-95 corridor. Lows in the 60s. Highs Mon 80-85. Highs Tue upr 70s-lwr 80s.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. As of 350 AM EDT Sunday .

Aforementioned upper ridge pushes offshore Tuesday night, out ahead of a potent upper trough dropping out of the northern plains toward the upper midwest on Wednesday. As we've noted over the past couple of days, GFS remains on the fast side of guidance, with the CMC/ECMWF on the slower side, with the 00z/UKMet about middle of the road. The latter blend closes off the trough into an upper low across the Ohio Valley on Thursday. As you'd imagine with a dynamic, deep closing off to our NW, 00z model timing of the frontal passage has slowed a bit. Frontal passage now modeled to be after 00z/Thu on into the day on Thursday.

As far as sensible weather goes, expect some overrunning showers will be possible late Tue night and Wednesday as the warm front lifts north across the area. The front then slowly crosses the area Thursday into Thursday night. Still some uncertainty to wade through as we get closer. Again, GFS timing would clear out Thu a bit faster than the remaining guidance. Still hedged toward WPC frontal timing, Which is heavily ECMWF/CMC/UKMet weighted.

Cool canadian high pressure then builds into the area late in the day Thu into Thu night, with clearing from SW to NE Thu night into Friday Dry, much cooler. and dare we say Fall- like . for Fri/Sat. Highs Fri/Sat in the 70s, lows in the 50s to near 60 se. Typically cooler spots could easily see the upper 40s Fri and Sat nights.

AVIATION /14Z SUNDAY THROUGH THURSDAY/. As of 710 AM EDT Sunday .

Sub-VFR (MVFR to IFR, LCL LIFR) conditions over the VA piedmont into south central VA at sunrise this morning. A cold front near the Mason-Dixon line will slowly sink south toward the area this morning, and wl drop through the region later today. CIGs/VSBY will recover to VFR all sites through 12-14z. Some showers are possible over Hampton Roads area (mainly W-SW of KPHF/KORF) after 18z, coincident with frontal passage. However, with little moisture not anticipating much more than some passing clouds (4-6 KFT AGL) and some isolated shower activity. Areal coverage of any showers looks to be far too low to warrant mention in TAF at this point. The biggest change will be a switch in wind direction to the north this aftn.

Outlook: Some additional late night fog/low stratus Sunday night, with another quick return to VFR Monday morning. 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 early on Thursday.

MARINE. As of 400 AM EDT Sunday .

A high threat of rip currents is expected today for the southern beaches (VA Beach/Currituck). A moderate risk is likely for the northern beaches with waves around 3 ft with winds becoming NE this afternoon.

Weak high pressure was centered over the area and into NC this morning, while stronger high pressure was centered over the northern Great Lakes, pushing south and east. Winds were generally SW to NW around 10 kt or less over the waters, with waves on the the Bay generally around 1-2 ft and ocean seas 3 to 4 ft.

High pressure pushing down from the north later today will result in a more northerly and northeasterly flow later this morning and through the afternoon. Winds will become NE everywhere by this afternoon and remain NE tonight and Monday as high pressure remains in place just to our north. Winds increase to 10 to 15 kt by this afternoon especially from Cape Charles north. Winds gradually become E 10-15 kt Mon night, then SE Tue night through Wed. Winds speeds remain around 10 to 15 kt with seas 2-4 ft Sun through Wed, waves on the Bay 1-2 ft. Conditions will remain sub SCA through Tuesday.

A strong cold front approaches the waters from the W-NW late Wednesday into Wednesday night, before crossing the area by late Thu. Models disagree some with the exact timing of the front, however, the pressure gradient looks to really tighten ahead of the front late Wednesday afternoon and especially Wednesday night resulting in a strong southerly flow which could result in SCA conditions Wednesday afternoon. SCA conditions will likely persist Thursday into early Friday as the front pushes through and winds become northwest behind the front. Winds should start to decrease Friday night.
