Maryland starts the morning with dry pavement and a light spring breeze, but clouds are already building over the Inner Harbor. That calm setup begins to shift by midday, as moisture pushes in and the air turns slightly heavier.
According to the National Weather Service, Baltimore, Towson, Columbia, and Annapolis will see a 40% chance of showers developing after 1 p.m. The peak impact window runs from 4 p.m. to 8 p.m., when light rain may create slick roads across I-95, I-695, and the Baltimore-Washington Parkway. Low-lying streets near the harbor and underpasses in downtown Baltimore could see brief pooling, reducing visibility and increasing stopping distance during the evening commute.
This is part of a broader system moving east from the Lower Mississippi Valley, feeding moisture into the Mid-Atlantic while temperatures remain below average. Highs will reach near 67°F today, but the damp pattern lingers into the weekend.
A secondary round of scattered showers develops Saturday afternoon after 2 p.m., though coverage remains limited near 20%. By Sunday, skies clear with sunshine returning and highs near 63°F, offering a brief stretch of calmer weather.
The warming trend builds early next week, with temperatures climbing into the 70s Monday and near 80°F by Tuesday. However, additional showers return midweek as the next system approaches.
Plan for slower travel during the 4 p.m. to 8 p.m. window today, avoid water-covered roads near low spots, and allow extra time on major routes as showers move into the Baltimore area.
