BALTIMORE, MARYLAND — A late-night severe weather update indicates the main line of storms associated with a cold front will likely move through the Baltimore, Maryland metro area later than previously expected, with the most organized activity now projected between 7 PM and 9 PM.
While scattered strong or severe storms remain possible during the afternoon, the primary concern centers on the more organized evening line pushing east across central Maryland and southern Pennsylvania.
Evening Timing Shift for Baltimore Metro
Forecast models show the cold front’s main storm line advancing steadily eastward across western Maryland during the evening hours.
By around 8 PM, the line is expected to extend from:
- Hagerstown, Maryland
- Frederick, Maryland
- Westminster, Maryland
and push directly into:
- Baltimore, Maryland
- Gaithersburg, Maryland
- Annapolis, Maryland
Temperatures ahead of the front remain mild in the upper 50s to low 60s across Baltimore, Bel Air, Elkton, and Dover, Delaware, providing enough instability to support strong thunderstorms.

- Hagerstown, Maryland
