Weather Authority: 8 a.m. Friday Update
FOX 29's Sue Serio has a look at when the cold temperatures will return and when snow and rain will start on Sunday.
PHILADELPHIA - Mild conditions will continue Friday, but another polar vortex will send the Delaware Valley back into the freezer on Saturday – marking the start to a wild weather weekend.
Temperatures are forecasted to rally back into the mid-to-upper 40s during the daylight hours on Friday, with Philadelphia and the suburbs likely to get up around 50 degrees.
Forecasters anticipate a polar vortex will bring a blast of Arctic air to the region around dinner time on Friday.
Saturday morning wind chills will be as low as single digits, and could even drop below zero degrees. High temperatures will only be in the 20s with wind gusts of 30-40 mph expected during the day.
A wind chill advisory will be in effect in parts of the Lehigh Valley, meaning dangerous wind chills could go as low as -20 degrees.
By the time Sunday rolls around, temperatures should return to the 30s and our focus will be shifting to potential snowfall.
Expect snow to begin falling in parts of the area early Sunday evening between 5-8 p.m.
From 8 p.m. to midnight, snow will continue to fall in areas north and west of the city. In areas to the south and east, expect the precipitation to change over to mostly rain.
Early Monday morning, the changeover will continue, with snow changing to sleet to the north and west. Rain will continue to fall in the city, and areas to the south and east overnight.
