| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 304pm EDT Monday Jun 22 2026 .WHAT HAS CHANGED... Severe Thunderstorm Watch Number 375 was issued and remains in effect until 9PM for the entire forecast area with the exception of Garrett County, Maryland. .KEY MESSAGES... - 1) Strong to severe thunderstorms along with locally heavy rainfall possible this afternoon into early this evening. - 2) A strong cold front brings back rain and thunderstorm chances for this upcoming weekend. KEY MESSAGE 1...Strong to severe thunderstorms along with locally heavy rainfall possible this afternoon into early this evening. A strong low pressure system is forecast to track just north of the forecast area through this evening with the associated warm front already lifted north through the area. Showers and thunderstorms are currently tracking eastward from the Alleghenies towards the metros with strong to severe thunderstorms forecast for this evening. In the wake of the warm front, there is plenty of instability which combined with strong flow aloft yields conditions favorable for scattered strong to severe thunderstorms. Primary hazard is damaging wind gusts with storms capable of producing 60mph wind gusts. Additionally, a brief tornado is possible mainly NE of DC. Severe Thunderstorm Watch Number remains in effect until 9PM for the entire area with the exception of Garrett County where the warm front had not lifted through yet. In addition to the severe thunderstorm threat, any storms will be efficient rainfall producers are PWATs (Precipitable Waters) near 2". Storm motion is expected to be progressive enough to limit widespread flooding concern, although sensitive areas with poor drainage and/or urban areas may experience flash flooding. Showers and thunderstorms continue moving east across the area through this evening with convection dwindling around 9PM. Rain showers continue through midnight with low clouds and fog expected overnight. The cold front associated with the aforementioned low pressure system pushes across the forecast area early Tuesday morning with a surface low forecast to develop along the front overnight. This will yield rain showers and a few thunderstorms on Tuesday. Conditions dry out in the afternoon as high pressure builds over the region through Wednesday. KEY MESSAGE 2...A strong cold front brings back rain and thunderstorm chances for this upcoming weekend. A strong upper-level trough forms over the Upper Midwest before transitioning over the Great Lakes later this Wednesday through Friday, with a stemming cold front tracking through the Mid-Atlantic by the start of the weekend. Southeast winds help to provide moisture as this front moves through, increasing humidity as well as chances for showers and thunderstorms late in the week. Exact timing of the front remains uncertain at this time, with current ensembles showing a range of possible times through the weekend where storms could form along the front. Damaging wind gusts remain the primary hazard with any storms, but additional impacts remain uncertain at this time. Otherwise, expect conditions to remain hot & humid before and after the frontal boundary moves through, with temperatures nominally decreasing after the front passes but quickly increasing to mid-90s with dewpoints approaching 70 by next Monday. Upper level ridging moves into the region early next week, reducing rain chances. Marine SMWs are likely across the waters this afternoon and into the evening as strong to severe storms track across the waters. Outside of storms, SCA (Small Craft Advisory) criteria winds continue through this evening. Winds diminish overnight with additional SCAs (Small Craft Advisories) in effect for Tuesday afternoon. High pressure builds overhead on Wednesday with winds forecast to stay below Small Craft Advisory criteria. Winds diminish below SCA (Small Craft Advisory) thresholds by late Friday morning and remain so through the weekend. Southerly winds shift westerly late Saturday evening, with showers and thunderstorms possible over the waters Friday and Saturday afternoon and evening.
