This winter, Southeast PA can expect below average temperatures in December, with slightly above average temperatures in January and February, followed by below average temperatures in March. We anticipate winter to get off to an early start with a cold, snowy month of December.
A mid-winter thaw is then expected in January, possibly into February, The majority of precipitation may fall as rain and during this period. Ice storms will also be a concern during this time especially in the Lower Susquehanna Valley and Cumberland Valley. An active, chilly end to winter is anticipated with a few late season winter storms possible in March. If you have yet to see our Official 2017-2018 Winter Outlook, click here to read it.
