Harrisburg, PA – The early-December cold snap is showing no signs of letting up. According to the NOAA Climate Prediction Center’s 8–14 Day Outlook, issued December 1, Pennsylvania will stay in a colder-than-normal pattern from December 9 through December 15, as Arctic air continues to grip much of the Northeast and Great Lakes.
Highs will remain mostly in the 30s across central and western Pennsylvania, with lows dropping into the 20s or teens in northern counties. The Pittsburgh area could see several rounds of light snow, while Erie may pick up lake-effect snow as cold air passes over the Great Lakes.
Farther east, Philadelphia and Allentown may see more of a rain-to-snow mix, with slick conditions possible during morning and evening commutes midweek. NOAA also expects above-normal precipitation, suggesting a more active storm track through mid-month.
In contrast, much of the West Coast and southern U.S. — including California, Texas, and Arizona — will experience above-average warmth and dry conditions. For Pennsylvania, though, the story remains the same: a stubborn chill, frequent clouds, and the continued threat of snow and ice through mid-December.
Forecasters hint that a brief warm-up could arrive closer to the holidays, but until then, residents can expect another week of true winter weather.
