981 FXUS61 KAKQ 181155 AFDAKQ AREA FORECAST DISCUSSION National Weather Service Wakefield VA 655 AM EST Tue Nov 18 2025 .SYNOPSIS... High pressure moves offshore this afternoon ahead of a low pressure system, which will bring a quick chance of rain tonight through early Wednesday morning. Primarily dry Wednesday and Thursday as high pressure returns. && .NEAR TERM /THROUGH TONIGHT/... As of 320 AM EST Tuesday... Key Messages: - Low pressure moves in late today and tonight, bringing rain chances for the local area, highest amounts NE. The latest WX analysis indicates a potent upper trough over Atlantic Canada, with an upstream ridge into the western Great Lakes. At this surface, ~1023mb sfc high pressure is centered over the local area bringing cold and clear conditions early this morning. Temperatures are mostly in the upper 20s to lower 30s, and should drop off a few more degrees through sunrise. at the immediate coast in SE VA, light onshore flow is keeping readings in the 40s. High pressure slides offshore later this morning, as low pressure moves east from the mid MS Valley to the lower OH Valley this aftn, lifting a warm front towards the region. Mainly sunny this morning, with increasing high clouds late in the morning, and thickening/gradually lowering clouds this aftn (especially northern portion of the FA). The general setup has not changed much this cycle, with rain that will attempt to arrive from W-E late in the afternoon, initially having to overcome a rather dry airmass as forecast soundings depict a rather dry sub-cloud layer. Therefore, will only have PoPs over the far north prior to 00Z. Likely to categorical PoPs spread across the north through the evening, but taper off to low chc across central VA with mainly dry WX over the south. The trailing upper trough dives ESE through the local area after midnight, and shifts offshore after 12Z Wed morning. The highest rain chances, 80%+ are primarily from Caroline Co and pts east through the northern Neck and the MD eastern shore, though a few hrs with likely PoPs does extend south across most of VA after midnight with the help of the upper trough. However, QPF amounts look meager across the southern 1/2 of the CWA, generally 0.10" or less, while GEFS/EPS probs for 0.50" or greater are around 50% to the N/NE of the track of the vort max across the MD eastern shore. High temperatures today will range from the upper 50s/lower 60s in the far south, to the lower 50s for the north, with some upper 40s possible in the northern piedmont if thicker cloud cover arrives earlier. Low temperatures will not be as chilly given clouds and rain, and range from the upper 30s N to the mid 40s S. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY/... As of 330 AM EST Tuesday... Key Messages: - Mainly dry and mild Wednesday and Thursday. Low pressure pushes offshore Wednesday with any lingering light showers moving offshore between 12-15Z. Weak high pressure building in from the W will lead to dry conditions, though some low level moisture may linger, especially over NE portions of the FA. Becoming partly/mostly sunny central and south, and partly- mostly cloudy NE with high temperatures ranging from the mid 50s N to the mid- upper 60s south central VA and interior NE NC. Partly cloudy Wednesday evening, with increasing clouds overnight. Lows will be mild, generally in the low-mid 40s. Partly sunny south and mostly cloudy north on Thursday with high temperatures ranging from the mid 50s NE to the mid 60s south central VA and interior NE NC. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... As of 340 AM EST Tuesday... Key Messages: - Passing disturbances bring chances of light rain late Thursday night through Saturday. - Mainly dry Sunday-Monday with temperatures near to slightly above normal. Weakening low pressure tracks from the Great Lakes to the northeast Thursday night into Friday, with the trailing (but weakening) cold front dropping into the area Friday night into Saturday. This will produce occasional rain chances Thu night through Sat (highest chc Fri night/Sat). Spread in the model guidance has continued to improve, and overall shows weak high pressure and dry conditions by Sunday and Monday. Mild with highs Fri-Sat in the upper 50s to lower 60s NE to the upper 60s to lower-mid 70s far south. Forecast lows are in the mid 40s to mid 50s Friday and Sat morning, then cooler late in the weekend into next week. The latest blended guidance depicts slightly cooler, but still near to above average temperatures Sunday and Monday. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... As of 655 AM EST Tuesday... VFR conditions across area terminals should persist into this evening but high clouds increase and thicken this aftn and evening as low pressure approaches from the W. Light rain becomes likely from RIC to SBY tonight, with a chance of scattered showers farther south as the aforementioned weak low pressure system tracks across the area. Degraded flight conditions are expected at SBY, with brief sub- VFR conditions possible at RIC, and the latest trends indicating predominant VFR conditions persist elsewhere. Primarily VFR then for Wednesday (though SBY may stay MVFR through midday Wed). Mainly VFR Wed night/Thursday as weak high pressure rebuilds over the region. Another chance for light rain arrives Friday into Saturday, as low pressure tracks N of the area Friday, followed by the associated cold front dropping into the region Saturday. The best chc for light rain is at the northern terminals. && .MARINE... As of 300 AM EDT Tuesday... Key Messages: - Generally benign marine conditions are expected through Friday. - Winds become elevated and northerly behind a cold front late Friday night into Saturday. High pressure has settled across the Mid-Atlantic region and winds have started to diminish in response. A few higher gusts are being observed in the northern coastal waters, but sustained winds have dropped below SCA criteria so all remaining SCAs have been allowed to expire. Seas are currently 2-3 ft, with waves generally measuring between 1-2 ft. The aforementioned high will gradually move eastward today, ejecting into the western North Atlantic by this afternoon. The gradient will remain very weak across the local waters, and as the high slides overhead, winds will become light and variable. Weak onshore flow is possible later this afternoon due to local effects of daytime heating. Benign marine conditions will continue through the remainder of the week. While winds will briefly increase again by mid-week, SCA conditions are not expected at this time. A cold front is progged to move across the area Friday night into Saturday, which would could bring a period of SCA conditions to the local waters, though CAA looks to be on the weaker side, so confidence in this is not high. Have kept the wind forecast below SCA through the weekend and into early next week. Seas will remain in the 2-3 ft range through the end of the week, while waves will be in the 1-2 ft range. Behind the front this weekend, seas are forecast to build to 3-4 ft, with waves in the Bay building to 2-3 ft (highest at the mouth of the Bay). && .AKQ WATCHES/WARNINGS/ADVISORIES... MD...None.
