Strong to severe storms were moving through western Maryland early Wednesday evening, expected to bring strong winds, hail and frequent lightning to the Baltimore area later, according to the National Weather Service.

A storm moving through Washington County and northeastern West Virginia about 5 p.m. was expected to bring some winds in excess of 50 mph. A line of storms stretched across West Virginia and into Pennsylvania. Parts of Harford and Baltimore counties, including Bel Air, Aberdeen and Havre de Grace, are under a severe thunderstorm warning until 8 p.m.

The storms are coming ahead of a cold front expected to pass through overnight, weather service forecasters said. Some storms could become severe, with damaging winds but a smaller risk of hail expected.

Storms are expected to continue into Thursday morning. Once a low-pressure trough crosses the region, drier and cooler air is expected to settle over the region Friday and Saturday, bringing sunshine and comfortable temperatures and humidity.
