Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 939 AM EST Wed Dec 11 2019

SYNOPSIS. Canadian high pressure will build across the region today through Thursday. A low pressure system will then develop in the Gulf of Mexico and push northward across the eastern United States Friday and Saturday, followed by another low pressure system that will approach the region Monday into Tuesday.

NEAR TERM /THROUGH THURSDAY/. The radar is now clear across the entire area, with the back edge of the cloud cover nearly out of the area as well. Any snow from this morning will quickly melt as mostly sunny skies are expected today due to Canadian high pressure pushing towards the area from the northwest. Highs today will be quite chilly, only reaching the upper 30s to low 40s. With gusty winds also present behind the front, wind chills will struggle to get above freezing for much of the area as well.

High pressure will continue to build across the region tonight into Thursday. The air mass is chilly, but not excessively or unusually cold for this time of year, with readings perhaps approaching 10 degrees below normal . a range which is quite normal this time of year. Lows tonight may reach the teens in the cold spots, so not even the coldest it has been so far this year. Highs on Thursday should be a little cooler (mid to upper 30s), with strong high pressure (~1040mb) set up to the northeast, which will continue to funnel cooler air into the region.

SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/. The Canadian high pressure will slide east off the coast Thursday night as low pressure develops along the Gulf Coast, then heads north. A wedge will remain, however, so cold air damming looks likely, especially Friday morning. Warm advection precip looks likely to overspread southwestern areas by mid- morning Friday, with the rest of the region likely seeing at least a bit of precip by day's end. The early arrival presents problems given the cold air mass in place, so freezing rain is a significant risk along the I-64 and I-81 corridors that we forecast for, stretching from Charlottesville to Staunton and perhaps as far north as Martinsburg. Further north and east, it appears more likely that temps will have a chance to rise above freezing before precip arrives, resulting in mostly or all plain rain. That all said, most precip Friday looks light, with the more significant rain moving in Friday night after temperatures are solidly above freezing (if only barely) across our entire area. Below freezing lows Thursday night will lead to highs in the 40s east of the mountains Friday, but 30s near I-81, with temps staying fairly steady Friday night with the rain.

LONG TERM /SATURDAY THROUGH TUESDAY/. Low pressure near the Delmarva Peninsula will lift northward into New England Saturday. Expect rain showers during the day. As an associated front makes its way to the East Coast by Saturday night, rain showers will taper to become more isolated. Some upslope rain or snow showers will develop in the Potomac Highlands in relation to the upper level low that is providing support to the departing surface low.

Upslope snow showers could linger in the Potomac Highlands on Sunday with a gusty northwest wind. Elsewhere, colder and drier air will filter into the central and eastern zones in part to high pressure.

By Sunday night into Monday, a developing warm front to our southwest could bring us a chance for some light snow or light rain. As the warm front lifts northward Monday night, this wintry mix of snow and rain should become plain rain Tuesday ahead of an approaching cold front and its affiliated surface low pressure system. Milder air will be short-lived Tuesday before a cold front brings a rush of colder air into the area late Tuesday and Tuesday night. Upslope light snow and a chance of snow showers to the east could evolve with the rush of cold air Tuesday night.

High pressure will build in across the region on Wednesday. Expect below average temperatures to develop and continue.

AVIATION /14Z WEDNESDAY THROUGH SUNDAY/. VFR conditions expected through Thursday night. Gusty northwest winds at times today should relax later tonight. A period of freezing rain is possible at CHO early Friday, then up towards MRB later in the morning-midday, but otherwise, mainly rain is expected Friday and Friday night. Cigs and vsby likely to drop to IFR at times by Friday night with the rain.

MVFR conditions possible with rain showers Saturday. VFR conditions Saturday night through Sunday night. A few snow showers could venture across CHO and MRB terminals Sunday night, but shouldn't have any big impacts on the terminals. Winds light and variable Saturday becoming west 5 to 10 knots Saturday night. Winds increasing west-northwest 10 to 15 knots gusts 20 knots Sunday and Sunday night.

MARINE. SCA continuing at times through this morning, and a secondary boundary may reinvigorate winds tonight for a time. High pressure then should let winds relax to sub-SCA by Thursday afternoon. Light winds then should prevail through Friday night.

Small craft advisory conditions possible Sunday into Sunday evening as high pressure over the Great Lakes interacts with low pressure over New England.

LWX WATCHES/WARNINGS/ADVISORIES. DC . None. MD . None. VA . None. WV . None. MARINE . Small Craft Advisory until midnight EST tonight for ANZ531>533- 539>541. Small Craft Advisory until 6 PM EST this evening for ANZ530- 535-536-538-542. Small Craft Advisory until noon EST Thursday for ANZ534-537- 543.
