SYNOPSIS
A slow moving warm front will exit the local area this morning while a weak cold front tracks through later today. High pressure briefly builds in before a stronger cold front pushes across the region Friday evening into the night. High pressure returns late in the weekend into early next week.
NEAR TERM /THROUGH TONIGHT/
Mid morning update: A nearly stationary boundary stretches north to south from north-central MD down to southern Maryland this morning. To the east of the boundary, winds are out of the east, allowing low clouds/fog remain to remain in place over northeastern Maryland. To the west of the boundary, winds are out of the west, allowing low clouds to clear out. Some additional stratocumulus is developing to the west of the boundary as mixing deepens from western MD into the DC Metro.
This aforementioned boundary is expected to show little movement throughout the day, and could lead to a sharp temperature gradient between northeast Maryland and the DC metro. A few sprinkles could also be possible this afternoon across northeast Maryland in the vicinity of the boundary where low-level convergence will be maximized
Previous discussion follows
Gusts up to 15 to perhaps 20 mph are possible during the afternoon hours as the boundary layer becomes better mixed. The net downsloping effect behind this front will yield a warm mid- April day across the Mid-Atlantic. As 850-mb temperatures rise into the 10 to 12C range, dry adiabatic mixing would yield upper 70s to low 80s. This is indeed the forecast for the D.C. metro down into central Virginia as well as the Shenandoah Valley. The cooler spots will be over the Allegheny Front and northeastern Maryland where highs remain in the mid/upper 60s.
By this evening and into the night, winds continue to back with a resulting east-northeasterly flow. This onshore flow regime allows for a return of marine stratus to the forecast area. A cool and damp wind will yield a cooler night than previous days.
Forecast lows are mainly in the mid/upper 40s, with some low 50s across the I-64 corridor and in the Allegheny mountain valleys.
Any shower chances are expected to hold off until after sunrise on Friday.
SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/
An expansive upper trough extending across southern Canada into the Great Lakes region will support a pattern change into the upcoming weekend. Warm advection ahead of the attendant cold front will yield periods of showers on Friday. Total rainfall amounts are not terribly impressive, generally running around 0.10 inches, locally up to 0.25 inches in the higher terrain.
This is accompanied by a slight chance for thunderstorms, especially west of I-95. Despite mainly south to southeasterly flow, the mostly cloudy skies should keep temperatures down relative to Thursday. Those east of U.S. 15 will likely stay in the mid/upper 60s (locally a bit cooler in northeastern Maryland), with slightly warmer conditions to the west outside of mountain locales. Shower chances gradually come to an end from west to east overnight. Nighttime lows will range from the 40s over the mountains and along the Mason-Dixon Line, to low/mid 50s elsewhere.
Aside from a few lingering showers early Saturday morning over far southern Maryland, expect a dry day over the region on Saturday. Temperatures stay slightly above normal owing to a downsloping northwesterly wind. However, this round of winds should be much stronger than recent frontal passages. The latest forecast package calls for afternoon gusts of 20 to 30 mph, locally up to 35 to 40 mph along the Allegheny ridgetops. Some residual wind lingers into the overnight hours which will make for a chilly Saturday night. Forecast low temperatures range from the upper 30s to mid 40s, with near freezing conditions along the Allegheny Front.
LONG TERM /SUNDAY THROUGH WEDNESDAY/
A front will be draped along the southeastern states Sunday while high pressure extends eastward from the Plains to its north. Low pressure will be tracking along the front, spreading rain toward southern Virginia by Sunday evening. Model consensus continues to indicate rain will largely remain south of the forecast area, but there are still some 20-30 PoPs across southern zones. Even without the rain, Sunday will be a mostly cloudy and cooler day. Clouds will depart late Sunday night. Some valleys west of the Blue Ridge could drop into the mid 30s should skies clear and winds become light, which would pose a risk for frost.
The surface high will move closer on Monday, although there will be a compact short wave trough (or even closed low) overhead. While some extra clouds are possible, the chance for rain is currently low. Temperatures will be near or slightly below normal.
The high will remain in control to start Tuesday, and southerly return flow will result in a warm up. The next trough and associated cold front will approach late Tuesday into early Wednesday. Moisture may be limited, resulting in the highest shower chances along the Appalachians. Instability will also be limited, so thunderstorms appear unlikely. Shower chances linger into Wednesday to account for slower solutions. Otherwise, expect gusty winds and cooler temperatures behind the front as strong high pressure builds in from the northwest.
AVIATION /14Z THURSDAY THROUGH MONDAY/
A wavy stationary front currently extends from the Carroll County in north-central Maryland down toward Calvert County in southern Maryland. To the east of this boundary, a thick marine stratus deck has formed which is impacting KBWI and KMTN with IFR ceilings. This IFR deck has remained stubborn, and may take into the afternoon to ultimately mix out. Winds may hold out of the east to the east of this boundary through much of the day, while winds remain northwesterly to the west of the front with some gusts up to 15 knots or so. Heading into the evening and nighttime, winds back over to east- northeasterly which favors another round of low stratus. MVFR to IFR ceilings become likely late tonight into Friday.
Rain showers return to the forecast on Friday, accompanied by some slight thunder chances for the more western terminals.
Restrictions are expected to persist with MVFR ceilings remaining for portions of the day. A stronger cold front tracks through late Friday which should allow for a return to VFR conditions on Saturday. A gusty northwesterly wind is expected with forecast gusts up to 20 to 25 knots.
VFR conditions and winds AOB 10 kt are most likely for Sunday and Monday. Effects from low pressure will likely remain south of the area, but rain could near CHO Sunday evening.
MARINE
Wind fields across the waterways picked up earlier in response to a southeastward propagating outflow boundary. However, its influence has waned with below advisory winds being observed. A weak cold front pushes across the waters today which could bring near 18 knot gusts at times. Eventually a shift to east- northeasterlies is expected with another uptick in winds, particularly over the northern Chesapeake Bay. Some 20 knots gusts are possible as this occurs later this evening.
Rain showers are in the forecast on Friday, although the main thunder chances should stay west of the tidal Potomac and Chesapeake Bay. However, these details could change so check back for the latest forecasts. A stronger cold front arrives late Friday night into early Saturday. This leads to a strengthening northwesterly wind and likely Small Craft Advisories for Saturday and possibly into the night.
Overall winds will lessen Sunday, but some gusts may approach advisory criteria. Sub-SCA conditions are likely Sunday night and Monday as high pressure builds in from the west.
TIDES/COASTAL FLOODING
Tidal anomalies will hold steady or trend down slightly today with a brief period of northerly winds. Easterly winds develop tonight then become southerly Friday, which will result in rising anomalies. The greatest chance for minor flooding will be along sensitive shoreline (Annapolis, Straits Point, DC SW Waterfront) with the Friday and Friday night high tides, although it may be close in other locations. Water levels will drop southerly in gusty northwest postfrontal flow.
