Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 406 AM EDT Thu Apr 22 2021

SYNOPSIS. High pressure will build to our southwest today through tonight, before progressing offshore on Friday. Low pressure will pass overhead Saturday night, before moving off to our northeast on Sunday. High pressure will move back in for the early to middle portions of next week.

NEAR TERM /THROUGH TONIGHT/. Low pressure has pulled away toward the Canadian Maritimes this morning, but upper level troughing remains overhead. Winds have slackened a bit overnight, but most locations have maintained westerly winds. Some locations in the Virginia Piedmont and Shenandoah Valley have decoupled, and those are the locations that have dropped to freezing. If more locations were to decouple, they could drop to freezing as well, but for now expect that most locations that maintain winds will stay just above freezing this morning. Snow showers are streaming down in northwest flow from Ohio and Pennsylvania. These snow showers should remain primarily along and northwest of the Allegheny Front through daybreak, but a few flurries may be able to spill over into the eastern WV Panhandle or northern MD early this morning.

Low-level west-northwesterly flow will be maintained today, and winds should pick back up again shortly after sunrise as mixing commences. While it won't be quite as windy as yesterday, winds should gust to around 30 mph out of the west-northwest through most of the day. Skies are also expected to become mostly cloudy today as a stratocumulus deck forms in response to mixing. A shortwave situated on the backside of the larger scale trough will pivot from the southern Great Lakes toward southwest Virginia today. This disturbance will spark the development of showers across West Virginia. Most of the activity will remain along and west of the Allegheny Front, but a few showers may spill over the mountains and into the central Shenandoah Valley or central Virginia later this afternoon. The showers should mostly be in the form of snow along the ridgetops, with rain showers at lower elevations, although a little graupel may mix in with some of the more convective showers. Some of these snow showers could be on the heavier side along the Allegheny Front from Grant County southward to Highland County, where most guidance shows snow squall parameter values increasing to well above one. Any accumulations should be minimal and relegated to the highest of elevations, with most spots even along the Allegheny Front rising above freezing.

This shower activity across southwestern portions of the forecast area should wind down this evening as daytime heating is lost and the aforementioned shortwave pivots off to the south and east. Winds will decrease again tonight, and more locations should decouple compared to early this morning. However the airmass will be a bit warmer. As a result, temperatures may drop to freezing again in locations that decouple. It will again be a close call as to whether many spots remain just above or just below freezing, so the Freeze Watch has been maintained.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/. The upper-level trough will progress off to our east on Friday, allowing high pressure to build to our south at the surface. With high pressure in control, mostly sunny skies and light winds are expected, along with warmer but still below normal temperatures. Most locations should see highs in the 60s.

The next shortwave and associated area of low pressure at the surface will approach the area from the southwest on Saturday. The day should start out dry for all, but clouds will be on the increase through the morning. Rain will overspread the area from southwest to northeast through the afternoon, and a soaking rain is expected for all through Saturday night. Rainfall amounts should generally be around a half of an inch to an inch for most.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. The long term features a general drying and warming trend. To start, low pressure will be pulling northeast out of the area Sunday. Some showers may linger, especially early, with a brisk northwest wind, but temperatures will not be nearly as chilly as what we are experiencing presently. High pressure will then build across the region to our north Monday before shifting south of the area Tuesday and Wednesday. This will cause northerly winds to shift southwesterly, providing a strong warming trend. All the while, heights will be rising significantly as the trough over the region Sunday is replaced by a strong ridge by the middle of the week. Thus, temperatures which will start off near normal Sunday and Monday will rise well above normal by Wednesday. Current forecast brings temps to the 80s Wednesday. After the showers pull away Sunday, dry weather should prevail thanks to the high pressure and building ridge.

AVIATION /07Z THURSDAY THROUGH MONDAY/. Winds have dropped off a bit overnight, but will pick up again shortly after sunrise, with gusts of 25 to 30 knots out of the west-northwest common throughout the daylight hours. Skies will become mostly cloudy, but ceilings will remain VFR. Winds will drop off tonight, but remain out of the west to west-northwest. Conditions will remain VFR through Saturday morning, but should deteriorate to sub-VFR Saturday afternoon through Saturday night in association with low clouds and rain as an area of low pressure moves through.

Lingering reduced cigs and vsby are possible Sunday, especially in the morning, as low pressure pulls out of the area. Otherwise, a gusty northwest wind Sunday will gradually dwindle as high pressure builds across the area Monday with VFR conditions.

MARINE. A Gale Warning is in effect for locations south of North Beach through 6 AM. Thereafter, a Small Craft Advisory is in effect for all location through today. Gusts to around 30 knots are expected through much of the daylight hours. Winds will decrease a bit overnight, but remain above at SCA levels overnight. As a result, the SCA has been extended through tonight, with the exception of the Upper Tidal Potomac, where it ends at midnight. Gusts overnight will be closer to 20 knots. SCA level winds may linger into Friday, especially over northern waters, but it will be marginal, so no headline decisions have been made as of yet.

Winds should drop below SCA values Friday night through Saturday morning, but should rise back up to SCA levels Saturday afternoon through Saturday night as an area of low pressure moves through.

Widespread Small Craft Advisory winds are expected as low pressure pulls out of the region Sunday. These winds gradually diminish Monday as high pressure builds across the region.

FIRE WEATHER. It will be windy and dry today with critical Rh's and winds, however, most places are now experiencing green-up with fuel moisture values now above critical levels. Therefore, not anticipating red flag conditions.
