Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 900 PM EDT Sat Apr 13 2024

SYNOPSIS
High pressure will continue to slide by to our south tonight. A weak area of low pressure will track to our north on Sunday, eventually pushing a weakening cold front southward through the area late Sunday night into Monday. Another disturbance will impact the region towards the middle of the week.

NEAR TERM /THROUGH TONIGHT/
Winds remain somewhat elevated, but should decrease rather abruptly over the next few hours following the loss of daytime heating and resultant mixing. Skies will remain mostly clear overnight, with temperatures dropping back into the 40s.

SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/
Flow aloft will become more zonal in nature tomorrow, with a broad belt of west-southwesterly flow extending from the Upper Midwest toward the East Coast. A shortwave disturbance will descend down in the west-northwesterly flow from the Great Lakes toward Upstate NY. A weak area of low pressure will accompany the shortwave, along with an attendant cold front which will drop southward out of NY into northern PA Sunday afternoon.
Locally, it will be a warm day to the south of the boundary, with temperatures climbing into the upper 70s to near 80 beneath partly cloudy skies. Thunderstorms are expected to form near the aforementioned frontal boundary up in PA Sunday afternoon. Much of this activity is expected to remain to our north during the daylight hours.

As we move into the evening and the first half of the overnight, these storms are expected to drift southward along with the frontal boundary, eventually reaching northern portions of the forecast area. This evening with the loss of daytime heating, the trend should be for these storms to gradually weaken as they move in from the north, but a few stronger storms can't be ruled out. The environment will be an uncommon one for this part of the country, with steep lapse rates of 7-8.5 C/km in place as an elevated mixed layer moves in aloft. If storms do persist as they track into the area, some instances of large hail may be possible. SPC currently has portions of northern Maryland and the West Virginia Panhandle outlooked in a Marginal Risk for severe thunderstorms.

The frontal boundary will continue to drift southward across the area on Monday. A few storms may try to form along the front from central Virginia to southern Maryland Monday afternoon, but conditions should remain dry for the vast majority of the forecast area. High temperatures will range from the mid 70s across northern Maryland to the lower 80s from central Virginia to southern Maryland.

LONG TERM /TUESDAY THROUGH SATURDAY/
A warm front will approach from the south Tuesday afternoon into Tuesday night. Showers and perhaps a rumble of thunder could accompany the front in parts of the region. High temperatures will reach the middle 70s for most.

With a warm front moving into and across Pennsylvania Wednesday and Wednesday night, a leeside trough of low pressure could setup in our region and be aligned north to south. It is both behind the warm front and ahead of and along this leeside trough that additional showers and thunderstorms could develop during the warmth of the day Wednesday afternoon and evening. Highs again will reach the middle to upper 70s.

There could be a break in shower and thunderstorm chances Thursday into Thursday night as weak high pressure develops on the west side of the leeside trough. Most of any showers and thunderstorms may be more focused near the Mason-Dixon region through the course of the day on Thursday. Highs on Thursday could reach the upper 70s to lower 80s.

By Friday, a cold front will trail an area of low pressure in the Great Lakes and push across the region later in the day Friday into Friday night. This cold front will increase our chances for showers and thunderstorms again. Highs Friday, due to increased cloud cover and increased coverage of showers and thunderstorms, will be a few degrees less with temperatures reaching the lower 70s.

AVIATION /01Z SUNDAY THROUGH THURSDAY/
Winds are quickly tapering off after sundown as expected this evening. Mostly clear skies are expected overnight with no flight restrictions expected.

Winds Sunday will turn out of the southwest, and may gust to around 20-30 knots at times. Northwest winds are forecast for Monday, with gusts of 15-20 knots possible at times.

VFR conditions Tuesday through Wednesday. Sub-VFR conditions possible in heavy downpours from showers and thunderstorms Wednesday evening. Winds northeast then southeast 5 to 10 knots Tuesday and Tuesday night. Winds south 10 to 15 knots gusts up to 20 knots Wednesday. Winds southwest around 15 knots gusts 20 to 25 knots Wednesday night.

MARINE
SCA conditions will persist through around 02z tonight before diminishing quickly thereafter.

Small Craft Advisories have been hoisted for Sunday as well across all waters in southwesterly flow. Sub-SCA northwesterly winds are then expected on Monday.

No marine hazards Tuesday through midday Wednesday. Small craft advisories possible late Wednesday and Wednesday night.
Winds northeast becoming southeast 5 to 10 knots Tuesday and Tuesday night. Winds southeast 10 to 15 knots early Wednesday, then increasing south to southwest 15 to 20 knots late Wednesday and Wednesday night.
