Washington, D.C. – Drivers across the Baltimore-Washington corridor could encounter repeated wet roads, lightning delays and reduced visibility through the next several days as a slow-moving frontal boundary keeps showers and thunderstorms active across the Mid-Atlantic.
According to the National Weather Service in Baltimore/Washington, on-and-off rain showers are expected through at least Tuesday as the stalled boundary meanders across the region. Thunderstorms remain possible each day, especially during the afternoon and evening hours, while temperatures gradually return closer to seasonal averages.
Communities from Washington and Baltimore to Frederick, Annapolis and northern Virginia could see scattered downpours capable of briefly slowing travel along Interstate 95, I-495 and the Baltimore-Washington Parkway. While widespread severe weather is not currently expected, isolated thunderstorms may still produce lightning and localized ponding on roads during heavier rain bursts.
High temperatures Sunday are expected to range from the upper 60s to middle 70s before climbing into the 70s and low 80s Memorial Day and Tuesday. Humidity levels will also increase slightly, helping fuel additional rounds of afternoon storm development across the region.
Residents attending Memorial Day ceremonies, outdoor cookouts or travel events are encouraged to monitor radar conditions closely and move indoors if thunderstorms approach. Additional advisories or thunderstorm alerts may be issued through midweek if heavier rain bands develop over the same locations repeatedly.
