PHILADELPHIA (CBS) — March is typically a volatile month as Spring and Winter fight it out. In this case, Winter will win the battle but lose the war. Spring officially arrives tomorrow at 6:45PM but Winter will have one last laugh as up to 6″ of wet snow fall on parts of the Delaware Valley.

A Winter Weather Advisory has been issued for most of the region on Friday. Snow will overspread the area from the southwest between 7AM-9AM as an area of low pressure strengthens off the coast. Cold air will be locked in place to start but snow will have a hard time sticking, throughout the day, on treated surfaces due to recent warm temperatures and the high March sun angle. However, untreated roads and sidewalks will become a slushy mess as the day goes on and travel could be slick especially North and West of the city where precipitation stays in the form of snow.

Much of southern NJ and DE can expect less than an inch as warmer air changes the snow over to rain. The I-95 corridor will receive 1-3″ of snow before a changeover and 3-6″ is possible in the Lehigh Valley and across the higher elevations of the Poconos.

The rain/snow line will cut through the region from south to north and should linger around the city by the afternoon. Mixing will limit accumulations. The system is an all day event but moves out by 8PM. Temperatures on Saturday will rebound nicely to near 50 degrees but another cool shot will send temps back into the 40s for Sunday and Monday. The good news is that temperatures by the end of next week climb to near 60.
