Snow’s Gone, But Deep Freeze Expected to Linger
STATE COLLEGE PA – A brutally cold punch of Arctic air is expected to reinforce winter across Pennsylvania and surrounding states now that the weekend’s major snowstorm has left our area, forecasters at State College-based AccuWeather Inc. reported.
A winter weather advisory issued by the National Weather Service office at Mount Holly NJ claimed the mixed precipitation – snow and sleet, followed by heavy rain – that began Sunday shortly after 6 p.m. in western Montgomery, Berks, and western Chester counties had subsided by Monday morning (Jan. 17).
Strong winds are still present, though, blowing from the west at between 20 and 25 miles per hour through Tuesday at 1 a.m. Gusts of up to 40 to 50 mph are possible, it added. Watch out for falling tree limbs and debris, the weather service warned.
As the weekend storm departed, AccuWeather indicated two new and separate shots of cold air will prolong the freeze. Cold conditions will continue to grip the Northeast on Tuesday (Jan. 18) with high temperatures struggling to reach 30 degrees Fahrenheit, AccuWeather said. Its forecasters predicted this scenario would make for the longest stretch of cold air so far this winter:
- First (at top), a dip in the jet stream will open the doors for cold, frigid air to billow into the Northeast early next week; then
- AccuWeather meteorologists are watching a more potent shot of Arctic air that will move south from Canada and across the mid-Atlantic and Eastern Seaboard as early as mid-week. Its effects could last into late January, they added.
A cold surge Wednesday through Friday (Jan. 19-21) will be “thanks to a branch on the polar vortex that has traveled south into the U.S.,” AccuWeather meteorologist Joesph Bauer explained.
“These frigid conditions will spread eastward through the second half of the week with places like … Philadelphia (above) seeing the coldest day on Friday,” AccuWeather Senior meteorologist Adam Douty added.
Frigid conditions are expected to persist into the following week as another reinforcing shot of cold air will keep temperatures below normal as January starts to come to a close.
