Breaking news and the stories that matter to your neighborhood.
Light snow began to fall Tuesday morning in the Poconos, Berks County and the Lehigh Valley where temps remained below freezing. For areas around Philadelphia, rain started to fall in the afternoon. That precipitation continued into the early evening.
During the evening commute, cold air arrived before the rain ended, changing the rain over to snow in most neighborhoods. The Pennsylvania suburbs saw the change first with several reports of snow.
About two dozen schools closed Tuesday before the first flakes had even fallen. As the day went on, dozens of more schools, including Montgomery County's large North Penn district, dismissed students early.
New Jersey Gov. Phil Murphy announced that state offices were closing early "on a rolling basis" Tuesday afternoon. He said the decision was made due to the storm and the extreme cold that's expected to follow it.
Four to five inches of snow fell in many neighborhoods in the Lehigh Valley and Berks County with up to 5.5 inches falling in Hamburg.
Three to four inches fell in the Pennsylvania suburbs while only a coating to nothing at all fell in Philadelphia, most of Delaware, South Jersey and along the coast.
Cold air is now moving into the region. Winds will pick up on Wednesday sending the feels-like temperature plummeting to below zero. An isolated snow squall is possible Wednesday afternoon as temps drop and winds could gust to 50 mph.
Thursday will be the coldest part of the Arctic blast. On Thursday morning, low temperatures (without the wind chill) will be in the single digits and below zero in some neighborhoods. Feels-like temps could be 10 below in Philly and 20 below in the Lehigh Valley. High temps Thursday won’t get out of the teens.
How cold will it be? A low temp of 5 on Thursday would be more than 10 degrees colder than the predicted low in Oslo, Norway, on the same day.
Bitter cold continues through Friday with highs only getting into the low 20s.
Relief comes over the weekend with temps expected to be in the 40s by Sunday.
