Fall Weather, Nicole Santangelo, PSU
The first 5 days of December were quite mild ranging from near normal in the east to as much as 6°F above normal in the west, but the mild weather came to an end on Tuesday as a cold front crossed the state. High temperatures Wednesday returned to near normal levels, mainly in the 40’s, but will sink into the 30’s Thursday through Saturday and struggle to reach freezing on Sunday, except in far southeastern Pennsylvania which will top out near 40. Precipitation over the last 30 days has been above normal in far western counties, but eastern counties have been lacking, averaging 50-75% below normal before Tuesday’s rainfall.
Other than a few snow showers near lake Erie Thursday, the next chance for precipitation will be Saturday and Sunday as a disturbance crossing the state will kick off some light snow or flurries, especially in western parts of the state. Monday will be fair but still cold. Another cold front will cross the state Tuesday bringing some light snow to the state and ushering in a cloudy, windy, cold snap that will extend from Wednesday through Sunday the 17th.
Daytime highs for this period will only be in the teens and 20’s while low temperatures in the colder mountain areas could hit single digits. Longer term, the remainder of the month of December will average below normal in temperature and near normal in precipitation. With temperatures remaining cold enough for snow through most of the remainder of the month, one or two significant storms with frozen precipitation cannot be ruled out.
