.MARINE... Sub-SCA levels winds will continue through Thursday morning with high pressure overhead, but quickly pick up in the afternoon out of the south. SCAs are in effect for the Chesapeake Bay and lower Potomac zones Thursday afternoon and night due to southerly channeling. Winds drop back below SCA thresholds Friday into the weekend. Southerly winds transition northerly winds Saturday evening. Shower and thunderstorms will accompany this front Friday through the weekend. Some storms could be strong to severe, leading to the potential of SMWs each afternoon. Confidence in this is low at this time based upon timing and placement of surface features. Winds remain below SCA thresholds Sunday & Monday. Northerly winds shift easterly by Monday morning before shifting southerly later that evening. Update as of: 334 PM EDT Wed Jun 24 2026
