Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 211 PM EDT Fri Apr 12 2024

SYNOPSIS
Low pressure will track north of the Great Lakes region today, while an associated cold front progresses off to our east. A reinforcing cold front will move through tonight. High pressure builds to our south Saturday. A weak area of low pressure will pass to our north Sunday night into Monday, allowing for some precipitation to return. Unsettled weather may be possible late next week.

NEAR TERM /THROUGH TONIGHT/
An area of low pressure is continuing to track further north of the Great Lakes early this afternoon, with an associated cold front departing to the east of the area locally. A few showers are beginning to track across the area ahead of a reinforcing front tracking from the west. This will continue through much of the afternoon and evening before dissipating. Cannot completely rule an isolated thunderstorm later this afternoon, especially across the far western portions of the region as well as northeast MD. Otherwise, the main hazard for today are the gusty westerly winds across most of the area. Wind Advisories remain in effect across the Allegheny Front and Blue Ridge zones through Saturday afternoon. Outside of the advised area, sporadic gusts up to 40 knots will be possible, especially just east of the Blue Ridge and across NE MD. Highs today will top out in the mid to upper 60s across the lower elevations, with upper 40s expected for the higher terrain.

The reinforcing cold front will move through the area tonight.
The strongest wind field will move in behind this front. It's likely that many locations will remain windy through the night, especially in the mountains. Lows overnight should be in the 40s to lower 50s for most, with 30s in the mountains. A few upslope snow showers may be possible late tonight across the highest terrain (over 3000 ft). In those locations, a brief coating of snow may be possible overnight.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/
The tighter pressure gradient will continue across the area through parts of the day on Saturday as the low pressure system continues to push further off to the north of the region. Before then, gusty winds will continue to impact the area through Saturday afternoon at least. Confidence has increased in higher gusts tomorrow, therefore the Wind Advisory has been extended to include all zones along and west of the Blue Ridge. Further extensions may be needed leading up to the day on Saturday.
Clouds will likely begin to clear out by the afternoon hours on Saturday, with mostly dry conditions expected. Highs will top out in the mid to upper 60s for the lower elevations with 50s across the mountains Saturday afternoon. Overnight lows will drop down into the 40s Saturday night, with winds diminishing out of the west-northwest.

Southwest flow will build in on Sunday, with a weak shortwave moving across to the north. A few showers and isolated thunderstorms will be possible Sunday afternoon and evening with highs rising back into the mid to upper 70s for most areas.
Shower chances continue Sunday night with lows dropping down into the mid to upper 50s.

LONG TERM /MONDAY THROUGH FRIDAY/
A cold front will slide across the region Monday and Monday night. A lingering rain shower could accompany the front.
Otherwise, dry conditions and warm temperatures in the 70s are expected during the period with Monday night temperatures 7 to 10 degrees becoming cooler than Sunday night's lows with the passing front.

The front will stall briefly across northern parts of North Carolina before returning north as a warm front Tuesday afternoon into Tuesday night. Additional showers and perhaps a thunderstorm or two could develop along and ahead of the warm front in our CWA Highs on Tuesday will again reach the middle 70s.

As the warm front moves north into Pennsylvania on Wednesday, rain showers and a few thunderstorms could erupt with additional daytime heating and temperatures reaching the middle to upper 70s.

A low pressure system will move across the Great Lakes with a trailing cold front that is expected to move across our region Thursday into Thursday night. Most of the region will be dry to start Thursday into midday, before daytime heating and additional warmth and moisture triggers showers and thunderstorms Thursday afternoon. Highs on Thursday should make a run at the 80s.

AVIATION /18Z FRIDAY THROUGH WEDNESDAY/
Winds will continue to be quite gusty out of the west-southwest today, and remain gusty out of the west-northwest Saturday.
Gusts of 30 to 40 knots should be common through Saturday afternoon. A few showers and potentially even a stray thunderstorm may develop late this afternoon. The chance for a thunderstorm is far to low to mention directly in the TAFs (around 10-20 percent). Drier conditions are expected this weekend. It will remain breezy on Sunday, with winds out of the southwest gusting to around 15-25 knots.

VFR conditions Monday through early Tuesday. Winds northwest 10 to 15 knots gusts up to 20 knots Monday and Monday night. Winds becoming northeast then southeast 5 to 10 knots Tuesday and Tuesday night.

MARINE
A reinforcing cold front will move through tonight, causing winds to turn west-northwesterly tomorrow. Gale Warnings remain in effect for all waters through the day tomorrow. Gusts to near, or potentially even in excess of 40 knots will be possible over the waters during that time. Additional SCAs will likely be needed within southwesterly flow Saturday night into Sunday.

No marine hazards Monday through Tuesday night. Winds northwest 10 to 15 knots Monday and Monday night. Winds becoming northeast around 10 knots Tuesday and Tuesday night.

TIDES/COASTAL FLOODING
A strong offshore flow has developed and this will continue through Saturday before gradually weakening Saturday evening. Anomalies will continue to fall during this time. However, water level will still be close to minor flooding thresholds in sensitive areas (Washington DC, Annapolis, and Straits Point) since anomalies were high to start this morning and the flow will be south of west.

Anomalies will fall sharply tonight through Saturday and low water levels are likely later Saturday into Saturday night around times of low tide. The change from high anomalies to low anomalies will cause a strong current during this time.
