A Canadian high-pressure system that ushered frigid temperatures into the Tri-State area is expected to break its grip this week as the system moves off the East Coast, according to a National Weather Service spokesman.
Another cold front is headed to the area, but milder temperatures ahead of that system are expected to drive the mercury to about 49 degrees Tuesday, said Brian Lasorsa, a meteorologist with the National Weather Service in Sterling, Va.
The region will return to more normal conditions for January later this week. Wednesday’s high is expected to be 38 degrees and Thursday’s high will be about 39 degrees, according to the National Weather Service.
Although Lasorsa said it is a little early to tell what will happen this weekend, the National Weather Service’s forecast on Monday said temperatures could rise to 41 on Friday with sunny skies, and the temperature could reach 47 on Saturday, with mostly cloudy conditions.
The mercury plunged to 13.9 degrees at 6:10 a.m. Monday in Hagerstown, according to Hagerstown weather observer Greg Keefer’s website at i4weather.net.
The record low for Jan. 16 in Hagerstown was set in 1910, when the temperature dropped to minus 4 degrees, according to Keefer’s website.
