A low pressure system will travel just north of Pennsylvania Wednesday Evening into Thursday Afternoon. It will run into cold air across Northern Pennsylvania, with temperatures in the upper 20s during the onset of the event. Temperatures will slowly rise Wednesday Night as snow continues to push east, before warm air finally floods in Thursday Morning.
This will be a very elevation-based event. Areas above 1500′ will see the most snowfall. The majority of snow will fall Thursday Morning. Below is an in-depth area-by-area forecast.
