Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 254 PM EST Tue Feb 18 2025

SYNOPSIS
Arctic high pressure remains centered over the north-central U.S. this week. Meanwhile, an area of low pressure taking shape over the Mid South will track to the Carolinas and off the East Coast Wednesday into Thursday. High pressure will take over late in the week, and a gradual warm up into the weekend.

NEAR TERM /THROUGH TONIGHT/
In the wake of a week mid-level frontal boundary, seeing some wave clouds show up in visible satellite. This is paired with brisk conditions at the surface, with temps in the 30s to low 40s and winds gusting to around 20 to 25 mph.

Later tonight, clouds will increase and precipitation will approach west-central VA as low pressure over the Mid South tracks eastward. Most precipitation will likely hold off until around or shortly after daybreak on Wednesday, but some snow is possible after about 3-5am over Highland County down over to Wintergreen.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/
No significant changes are noted with the forecast today compared to overnight, so we will start there. Winter Weather Advisories were issued for portions of central VA, the VA Piedmont, southern MD, and even western Pendleton County in WV.
This event remains rather complex in nature, but aside from a few outliers, model guidance has really remained consistent today with heaviest snow remaining well to our southeast.

A southern stream shortwave and associated surface low will scoot by to the south, passing offshore of the Carolinas Wednesday into Wednesday night. Most precipitation with this low will stay south of I-66 and mainly near and south of I-64 given the flatter and more progressive southern track and abundant dry air to the north. There was a slight bump to the north with this package, but still not expecting significant accumulations outside of the areas listed. The northern extent of this event is likely to have a very tight gradient, and areas north of that gradient may see no snow at all. In fact areas north of I-66 may even have to wait until Thursday morning to see any accumulation.
Areas in the advisories however can expect around 1-4 inches, depending on location.

A strong northern stream upper low will pass overhead Thursday, and may very well result in scattered to perhaps widespread snow shower activity depending on available moisture and any interaction with the increasingly distant offshore low. Added a few tenths to just under an inch of accumulation with this round of snowfall over much of the area. Additionally, for areas along the Allegheny Front, upslope snow showers pick up Thursday afternoon through Thursday night, which could result in some significant accumulations in these areas. Winter Weather Headlines may be needed for this event separately in the near future.

Lastly, wind also becomes a threat on Thursday, especially in the mountains. In turn, this will also bring Cold Weather Headlines in the picture given that temperatures will be well below normal.

LONG TERM /FRIDAY THROUGH TUESDAY/
The upper trough will be moving off the coast Friday morning while the strong surface high builds toward the Mid Mississippi Valley.
Some upslope snow showers will linger before tapering off during the afternoon. Gusty northwest winds will continue through the day, generally 30-40 mph in the lower elevations. Temperatures to around 10 degrees below normal are expected Friday and Friday night.

The surface high will move overhead Saturday, allowing a warming trend to begin. However, temperatures will remain below normal in the lower to mid 40s. A shortwave trough will cross the area Saturday night. There's a lot of uncertainty with how much moisture will be available. The greatest precipitation chances would be along the Alleghenies. However, if precipitation does occur, it could be wintry in nature.

Temperatures will moderate further Sunday into Monday as high pressure becomes positioned to the south and east, reaching near to slightly above normal levels. Another trough will move toward the east coast later Monday into Tuesday. With the primary low track well to the north in Canada, there is again some uncertainty how much moisture will be available locally.



AVIATION /20Z TUESDAY THROUGH SUNDAY/
Winds will be somewhat steady state, in the 20 to 25 knot range, until diminishing this evening. Mid or high level wave clouds are possible today, otherwise VFR conditions prevail.

Low pressure will track south of the area Wednesday into Wednesday night. The highest chance for snow and sub-VFR conditions is at CHO, although the metro terminals could see a period of light snow as well.

Thursday may actually be the best chance for snow at the metro terminals, though it will be sporadic in nature. During heavier snow showers, could briefly see VSBYs reduced to IFR.

VFR conditions are expected Friday through Saturday. NW winds may gust 25-35 kt Friday before diminishing Friday night and turning light and southwesterly Saturday.

MARINE
A large area of high pressure will descend into the north- central U.S. Since the high won't be directly overhead, west- northwest winds will only gradually diminish today, with northerly channeling expected tonight.

Lighter winds are expected Wednesday. Locations along the bay could approach advisory criteria Wednesday night depending on the strength of low pressure to the south. Solid SCA to possible gales are anticipated Thursday into Friday. A Gale Watch was issued Thursday afternoon into Thursday night as a result.

Strong northwest winds continue Friday. Small Craft Advisories are expected with gales possible. Winds gradually diminish Friday night but advisories likely continue. Lighter southwest winds are expected Saturday as high pressure moves overhead. Winds may become more westerly by Sunday.
