PHILADELPHIA (CBS) — After mild temperatures accompany us through midweek, a cold front is set to traverse the area on Thursday and open to door to a resurgence of cold, Canadian air. This arctic air will set the stage for a wintry mix/snow event for the Delaware Valley on Friday.

Precipitation will begin as rain across much of the area Thursday night with snow and sleet mixing in after midnight. As the mid-levels of the atmosphere cool dramatically and surface temperatures drop into the 30’s, a period of all snow is possible in Philly and surrounding suburbs Friday morning.
