We started off Tuesday with record cold across Central PA. The thermometer recorded 0 degrees at Harrisburg International Airport, the coldest reading for the day, and the coldest on any day since 1996. Beyond the airport, many neighborhoods dipped into the negative numbers for lows. But it is the winds making it feel dangerously cold outside. Westerly winds are keeping wind chill temperatures in the -15 to -25 degree range. Frostbite and hypothermia are serious concerns at those levels, so plan accordingly.
For the afternoon we expect to only reach a high of 9, easily achieving another record for the coldest afternoon high temperature for this date: January 7th. By evening the winds will start to wane a bit, but it will remain breezy through the overnight with temperatures still dipping back to around 5. Expect clear skies with wind chilly values remaining well below 0 degrees.
The slow thaw will begin starting Wednesday as temperatures bounce back into the 20s. By the weekend, the readings on the thermometer will jump all the way up to near 50 with rain possible for both Saturday & Monday. The temperature roller coaster this winter has been quite the wild ride.
