Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 1022 AM EST Tue Dec 10 2019

SYNOPSIS. A cold front will cross the area this afternoon. A weak wave of low pressure will pass by to the southeast as it rides northeastward along the front tonight. Canadian high pressure will then build across the region Wednesday afternoon through Thursday. Another, stronger low pressure system will then develop in the Gulf of Mexico and push northward across the eastern United States Friday and Saturday.

NEAR TERM /THROUGH WEDNESDAY/. Latest surface analysis shows low pressure over central Quebec, with the attendant cold front draped south from there along the western Appalachains and down to the Gulf Coast. Meanwhile, a stationary front is draped from New York City down through the central Carolinas and northern Georgia. A weak area of low pressure also exists at the intersection of the two over northwest Georgia.

PREVIOUS DISCUSSION: The cold front will make steady progress eastward today, crossing the metro area this afternoon. The warm front is likely to struggle to make further progress north, however, so while mild temperatures in the 50s are likely across the region, the 60s may be harder to come by than earlier anticipated, possibly being confined to eastern Virginia and southern Maryland. Part of the reason for this is that during peak heating, a band of showers just ahead of the cold front appears likely to cross the region, which will limit the effectiveness of daylight (though actual sunshine will likely be hard to come by regardless). After the front crosses the region, temps will start to fall, and by early evening, most of the region will be slipping back into the 40s.

Temps will continue to slide down through tonight, with most areas approaching if not reaching freezing by early Wednesday morning. As a strong jet streak passes to the north and a weak wave develops on the cold front, a renewed band of precipitation appears likely to develop. However, the position, intensity and timing of this band remains uncertain, with some models pretty meager (perhaps due to excessive dry air intrusion behind the front) while others significantly wetter. Thus, confidence in snow accumulations remains fairly low. Have mostly maintained inherited forecast, though did cut back accums in western MD where dry air appears more likely to cut amounts, at least based on the latest guidance. Even where snow does accumulate, amounts on roadways will be substantially less, if there are any at all, than what accumulates on grass and car-tops, and our forecast is for the latter, not the former. That said, there is still a significant risk of an advisory level event north and west of I-95, either side of a line from Westminster MD southwest to Staunton. As the precip may linger into the early part of rush hour, the very low criteria in the metro may even necessitate advisories right to Baltimore and DC. However, with uncertainty remaining high, have opted to hold off on any advisories. The most likely locations to receive advisory snow, however, remains the southern Shenandoah Valley and particularly adjacent Allegheny and Blue Ridge mountains.

Precip moves out quickly Wednesday morning, and sunshine will return. Combined with warm ground and temps in the 30s to low 40s, much of the snow should end up melting.

SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/. Canadian high pressure will dominate Wednesday night through Thursday, with dry conditions and chilly, though not really unseasonable, temperatures. Lows may reach the teens Wednesday night in spots, and highs Thursday likely stay in the 30s across much of the region. Cold, but not really unusual for mid-December.

The next system organizing near the Gulf Coast will start to bring warm advection northward Thursday night. While odds are not up to 50 percent yet, an increasing number of models try to bring precip into our southwestern and even central zones as early as pre-dawn Friday. With temps likely below freezing (but not quite as cold as Wednesday night), and warm air aloft, freezing rain is a possibility. Will need to watch this potential closely.

LONG TERM /FRIDAY THROUGH MONDAY/. High pressure along the mid-Atlantic Coast will continue to weaken and lift to the northeast Friday. Low pressure will push up from the south and bring a chance for some moderate precipitation. Many places could be at or below freezing Friday morning to midday when the precipitation arrives; thus, the threat for some freezing rain at the onset is real. The best location to encounter any freezing rain would be the Potomac Highlands, Shenandoah Valley, the central Blue Ridge Mountains, and even a little to the east of the mountains. As time goes on Friday, temperatures will modify and allow for freezing rain to become plain rain. Rain will become more showery or isolated Friday night.

Low pressure will exit to the north Saturday morning; thus, partial clearing skies expected Saturday afternoon and Saturday night. Dry weather should evolve Saturday night and continue through Monday morning. There could be a rain shower or two in the northern Potomac Highlands Monday morning.

By Monday afternoon through Tuesday night, the unsettled weather returns with a threat for more rain showers with the next low pressure system.

AVIATION /15Z TUESDAY THROUGH SATURDAY/. VFR conditions early will likely degrade to MVFR at times later today as showers cross the region in association with a cold front. Falling temperatures and a wave of low pressure will bring further restrictions tonight, possibly even a period of IFR vsby in snow, though extent and longevity of this is still very uncertain. VFR returns by midday Wednesday and persists through Thursday night, though a risk of FZRA exists down at CHO late Thursday night as the next system approaches.

Areas of rain and/or freezing rain will bring MVFR or IFR conditions to the terminals Friday through Saturday. Winds northeast and light Friday and Friday night, becoming northwest around 5 to 10 knots Saturday into Saturday night.

MARINE. Southerly flow likely to gradually diminish today as cold front approaches, but northwest flow picks back up behind it, so SCA's continue into Wednesday for some portions of the waters. By late Wednesday, building high pressure may help the gradient relax and allow winds to drop below SCA levels. However, a reinforcing shot of cold air Wednesday night could reinvigorate the winds briefly.

Small craft advisory conditions possible Friday night into Saturday for the central Chesapeake Bay. Winds northeast becoming southeast Friday night 10 to 15 knots gusts 20 knots. Winds becoming northwest 10 to 15 knots gusts higher Saturday.
