MARYLAND — Low temperatures Thursday morning could set a record in parts of Maryland, with a freeze watch and warning issued for some counties. Both weather advisories run from 1 a.m. to 8 a.m. Thursday, the National Weather Service said.

Part of Harford County is under the freeze warning, with sub-freezing temperatures as low as 31 expected.

Temps in the freeze watch are could also dip to 31 degrees. That area includes Frederick, plus Carroll, Baltimore, Montgomery and Howard counties.

Cities in the watch are: Hagerstown, Frederick, Eldersburg, Westminster, Reisterstown, Cockeysville and Germantown.

Baltimore's record low is 33, and the forecast is 35, the Washington Post's Capital Weather Gang said. At Dulles, the record is 32, and the forecast is 33. D.C.'s record of 33 will likely stand.

"Take steps now to protect tender plants from the cold. To prevent freezing and possible bursting of outdoor water pipes they should be wrapped, drained, or allowed to drip slowly," the National Weather Service said. "Those that have in-ground sprinkler systems should drain them and cover above-ground pipes to protect them from freezing."

Another round of frost or freeze conditions are possible during the overnight and early morning hours Friday night through early Saturday, the forecast said.
