AREA FORECAST DISCUSSION National Weather Service Wakefield VA 304 PM EST Mon Dec 4 2023

SYNOPSIS
A weak upper trough will swing across the region this evening.
High pressure will return for later tonight through Tuesday afternoon. A stronger upper trough will swing into and across the area late Tuesday night into Wednesday evening, then high pressure will build in for Wednesday night and Thursday.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/
As of 1245 PM EST Monday...

Pleasant wx and partly to mostly sunny skies prevail early this afternoon as a dampening shortwave aloft approaches from the west. Temperatures are mainly in the mid 50s to around 60F. This feature is progged to cross the FA this evening, which will result in an increase in clouds. However, the low-levels will remain dry so no precipitation is expected. The shortwave quickly moves offshore tonight, with clearing skies and light northerly winds expected. Lows will fall into the 30s in most areas.

SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/
As of 300 PM EST Monday...

Dry wx and slightly below normal temps are expected on Tue, as high pressure builds across the region. Highs will be mainly in the lower to mid 50s. Sunny to start the day, but clouds will be on the increase from the NW in advance of our next shortwave (with cloud bases potentially lowering to 8-12kft AGL by late aftn).

That next (deeper) shortwave trough will approach from the NW Tue night, and cross the area Wed into early Wed evening. Shower chances will arrive from the northwest by 10 PM-2 AM Tue night/early Wed AM, with a 20-40% PoP across much of the region (for rain showers)
during the remainder of the morning. Precipitation ends from NW-SE Wed aftn-early evening as the shortwave moves to our SE. While 1000- 500mb thicknesses will be ~530dm, the lowest ~2000ft appear to be too warm for any wintry precipitation to reach the ground.
Regardless, it will be cool and cloudy for much of the day, with highs only rising into the mid to upper 40s after starting in the mid 30s-lower 40s during the morning. Total QPFs are generally less than 0.10". Drying out (and colder) Wed night with diminishing winds inland, as high pressure builds in from the west. Lows Wed night in the mid to upper 20s inland/Piedmont, with lower to mid 30s near the immediate coast. Cool, mostly sunny, and dry on Thursday with light winds as high pressure settles over the area. Forecast highs are in the mid 40s-50F.



LONG TERM /THURSDAY NIGHT THROUGH MONDAY/
As of 300 PM EST Monday...

The surface high slides off the Mid Atlantic/SE Coast Thu night- early Fri before moving well out to sea by the weekend. Dry wx will prevail through Sat. However, during the second half of the weekend, widespread precipitation appears increasingly likely as a strong low pressure system quickly deepens as it tracks well to our NW. This feature will drag a cold front through the area on Sunday or Sunday night. At this time, there are significant differences between the global models with respect to track/timing of the system. For now, will go with likely (60%) PoPs for showers area-wide from Sun-Sun evening. As we get closer, specifics will become more clear. In addition to the showers, breezy south winds are possible in advance of the cold front. Lows Thu night in the lower to mid 30s in most areas. Increasingly milder from Fri through the weekend. Highs in the mid-upper 50s Fri, and in the lower to mid 60s Sat, and lower- upper 60s on Sun.

AVIATION /20Z MONDAY THROUGH SATURDAY/
As of 1245 PM EST Monday...

VFR conditions will prevail at the TAF sites through the 18z/04 TAF period with high clouds. Winds will be light and variable through early evening, before becoming NW-NE at around 5 kt tonight.

Outlook: Mainly VFR conditions are expected Tue into Tue night, as high pressure will be over the area then shifts offshore.
An upper level trough will bring clouds and isolated to scattered showers late Tue night into early Wed evening. Flight restrictions are possible (mainly due to CIGs).

MARINE
As of 300 PM EST Monday...

A weak pressure gradient exists across the area this afternoon, leading to light and variable winds across the waters. Seas are generally 2-3 ft w/ waves in the Bay 1 ft or less. A surge of cooler and drier air is expected to push S late tonight with winds increasing to 15-20 kt over the Chesapeake Bay and northern coastal waters. Gusts up to 25 kt will be possible, especially N of Windmill Point in the Bay and N of Parramore Island over the ocean. A small craft advisory has been issued from 05z-11z Tuesday from Windmill Point to Smith Point in the Chesapeake Bay. Further S, occasional gusts to 20-25 kt will also be possible, but wind probs are much lower here so will continue to monitor if a SCA eventually becomes necessary. Winds will diminish heading into Tues aftn as weak high pressure sits overhead. A stronger upper-level disturbance will dive SE towards the area Tues night-Wed, initiating low pressure formation off the Carolina coast. Winds turn N-NE early Wed at ~10 kt and then eventually turn NNW-NW at 20-25 kt with gusts to 30 kt later Wed into Thurs morning as the low moves further offshore and the pressure gradient tightens. Small craft advisories are likely during this period, with a short period of gale-force gusts possible over the coastal waters S of the NC/VA border. Given the marginal and short duration nature, decided to hold off on a gale watch at this time (local wind probs are 25-50% for 34 kt gusts). Winds gradually turn to the SW and become ~10 kt Thursday aftn, increasing to 10-20 kt Thursday night. Uncertainty remains heading into the weekend as a dynamic system looks to approach the region, with elevated southerly winds ahead of the cold front and elevated westerly/northerly winds behind the front Sunday through Monday. At least SCA conditions are probable, but significant timing differences remain among the guidance.

Waves in the Bay are expected to increase to 2-3 ft tonight with the surge in NNW winds, before diminishing to ~1 ft later Tues. Seas are expected to remain 2-3 ft through early Wed. Seas will increase quickly to 4-6 ft (3 ft nearshore) Wed aftn-early Thurs, with waves in the Bay increasing to 2-4 ft during this period. 3-4 ft seas and 1-2 ft waves are expected until ~Sat.
