Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
935pm EDT Wednesday April 17 2024

A stationary front will slowly lift northward as a warm front tonight, eventually pulling north of the region by early Thursday. A weak cold front will track through on Thursday before a stronger cold front arrives on Saturday. High pressure returns on Sunday and into early next week.

Near Term - Through Thursday
EVENING The line of showers and thunderstorms forecast to arrive tonight has been moving a bit faster than anticipated, now moving into far western Maryland. Currently it seems the line has begun to weaken as it approaches the mountains, consistent with earlier thinking, but will continue to monitor as the cold front moves through.

Previous discussion follows... Latest CAMs suggest that line will reach western MD around 02Z. Expect the line of convection over OH to weaken rapidly into showers as it enters Maryland tonight as it will be arriving around or after midnight.

Overnight, areas of low clouds and/or fog are likely particularly across north central MD.

Short Term - Thursday Night Through Friday Night
Warm front lifts into PA Thu followed by a weak cold front. Guidance shows a stable air mass and plenty of mid-level dry air to prevent convection, so only a windshift is expected.

Next cold front will cross the area Friday with showers expected. Air mass looks stable to prevent thunderstorms.

Long Term - Saturday Through Wednesday
A cold front will be draped further south early Saturday, with limited moisture availability but winds will be gusting 20 to 25 knots, especially along and west of the Blue Ridge Mountains. Highs will be in the 60s to low 60s for much of the area aside from the mountains, where mid 50s will be more common. Slightly cooler weather returns Sunday with continued dry conditions across the area with winds diminishing.

By the start of the workweek, a low pressure system to the south will continue to nudge eastward. A few light showers will be possible, mainly across the southernmost tier counties of our area. Temperatures will begin to climb back into the upper 60s to near 70 Monday and Tuesday. Renewed shower chances increase as a shortwave moves nearby from the Great Lakes region. Warming conditions will continue into midweek.

Showers possible across the northern waters tonight and Fri. Marginal SCA (Small Craft Advisory) gusts are possible Thu.

SCA (Small Craft Advisory) conditions are possible Saturday into Saturday night before winds weaken into Sunday. No other marine hazards are expected for the weekend.

Tides / Coastal Flooding
While some action stages may be reached through Thursday night (anomalies 1-1.5 feet above normal), the greater water level rises and potential for minor flooding will be toward Friday and Friday night as onshore or southerly flow develops ahead of a low pressure system.
