Severe storms were forming Thursday evening just north of the Mason-Dixon Line and were expected to bring risks of damaging winds, large hail and isolated tornadoes to the Baltimore area, according to the National Weather Service.
Storms are expected to reach the region between 6 p.m. and 8 p.m. Weather service forecasters described the risks in a special weather statement covering the Baltimore region:
THESE STORMS MAY BE CAPABLE OF PRODUCING LARGE HAIL...DAMAGING WINDS...FREQUENT CLOUD TO GROUND LIGHTNING AND VERY HEAVY RAIN. IN ADDITION...THERE IS A TORNADO THREAT.
A storm was moving through the Forest Hill and Churchville areas of Harford County shortly before 5 p.m., bringing frequent lightning, an inch of rain and 40-50 mph wind gusts, the weather service cautioned.
While the weather service's Storm Prediction Center does not expect to issue a severe thunderstorm watch across the region, forecasters there said isolated supercell storms are possible.
There is plenty of moisture in the air to fuel any storms, with dew points spending most of the day at 70 degrees or above.
