Tuesday turned out to be a confusing day for local weather observers.
The morning brought snow and other icy precipitation, and by late afternoon, a thunderstorm moved through the Hagerstown area.
Such things can happen in winter, said Heather Sheffield, a meteorologist with the National Weather Service in Sterling, Va.
The thunderstorm was the result of a line of showers ahead of a cold front, and the contrasting systems created instability in the atmosphere, Sheffield said.
The NWS and a Washington County 911 supervisor said there were no reported lightning strikes or other damage as a result of the thunderstorm.
Hagerstown weather observer Greg Keefer said 0.23 inch of precipitation fell in the city on Tuesday. The low temperature Tuesday in Hagerstown was 30.2 degrees at 3:17 a.m. and the high temperature was 47.6 degrees at 2:41 p.m., Keefer reported on his website at http://i4weather.net.
Considering Tuesday’s rain and the fact that the temperature was expected to drop to 26 degrees Tuesday night, HMTV 6 meteorologist Brittany Beggs said motorists should be on the lookout for possible black ice on roads during the night and early Wednesday morning.
Beggs said in her blog Tuesday that the next possible storm could hit Hagerstown on Friday and Saturday. But “models are not in agreement” and it’s hard to say now what will happen, Beggs said.
