Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 402 AM EST Sun Jan 17 2021

SYNOPSIS. High pressure will build south of the region Monday into Tuesday while low pressure remains over the eastern Great Lakes through mid week. A cold front will cross the area Thursday night. High pressure will build toward the region toward the end of the week.

NEAR TERM /THROUGH MONDAY/.

Clouds continue to build east of the mtns this morning and should continue to do that through the rest of the day with a generally cloudy/mostly cloudy day on tap. Snow showers should continue over the mtns through midday before shortwave-ridge axis builds overhead and activity wanes. A second and more significant round of mountain snow showers is expected late today through Monday as an upper low over the mid-MS valley pushes east. Snow accumulations will likely exceeed the advisory criteria but over a 24-hr period, but aren't likely to meet the 24-hr warning criteria of 8 inches. Also, very difficult to determine a 12-hr period of greatest accumulation as depth of moisture, temperatures, orographic lift, and winds are all fcst to remain the same over the entire 24-hr period. If I were to guess, perhaps the 03Z-15Z Mon time frame looks like the best period of most significant accumulation. Since a Winter Wx Advisory is already in effect, another one will not be issued at this time.

SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/.

Mountain snow showers will persist through mid week and likely beyond that in WNW flow and around longwave trough situated over the eastern half of the U.S. Elsewhere, generally fair weather and seasonable temperatures are expected with gusty W to NW winds as area remains between low pressure over the eastern Great Lks and high pressure over the Southeast.

LONG TERM /WEDNESDAY THROUGH SATURDAY/.

Seasonably cool with gusty winds out of the west-northwest at 20-30 mph on Wednesday, owing to the aforementioned cold front passage. This will keep wind chill values near to below freezing for much of the day. Otherwise, mostly dry across the region, aside from a few lingering upslope snow showers Wednesday morning along/west of the Allegheny Front.

Another frontal boundary will sweep through the region later Thursday, bringing a slight chance for some precipitation across the area. Timing will be key here, as some areas could see a rain/snow mix, or even all snow. The upper-level system ejecting out of the central Plains will be fairly weak, so have a hard time seeing much (if any) precip with this system outside of some potentially upslope snow showers once again. Recent model trends agree with this, as chance of precip has dropped greatly in the past few runs of guidance. So, will be coming down on POPs in the foreast for that period.

Progressively cooler Friday and Saturday as a reinforcing cold front pushes through Friday. This also appears to be dry in nature, but could see some more upslope snow out west. This should largely end by Saturday, as high pressure begins building in from the northwest, ushering in much cooler air into the region.

AVIATION /08Z SUNDAY THROUGH THURSDAY/.

BKN cigs 040-050 today with W winds 10-15kt. Clearing this evening before more clouds arrive late tonight and Mon in brisk NW flow. Winds will gust around 25kt Mon and Tue.

Gusty winds expected Wednesday out of the WNW, with gusts up to 30 knots possible at most terminals (maybe closer 35 knots at MRB and 20-25 at CHO). Expect VFR conditions during this time period though. Winds will relax Wednesday evening into THursday, with continued VFR conditions likely. There is a slight chance for some precipitation at all termiansl on Thursday, which could bring some flight restrictions, but that threat seems to have largely diminished with recent model runs.

MARINE.

SCA conditions into early afternoon and diminishing thereafter. However, winds may remain above SCA thresholds across the southern waters tonight and strengthen again Mon and remain brisk through Tue with gusts to around 25 kt. Expect winds to diminish at night.

Small Craft Advisories likely on Wednesday, with gusty WNW winds. Winds taper off into Wednesday evening and Thursday, but SCA's may still be needed, as it will be close to threshold.

LWX WATCHES/WARNINGS/ADVISORIES. DC . None. MD . Winter Weather Advisory until 7 AM EST this morning for MDZ001. VA . None. WV . Winter Weather Advisory until 7 AM EST this morning for WVZ501- 505. MARINE . Small Craft Advisory until 3 PM EST this afternoon for ANZ530>543.
