Sunny and frigid in the Philadelphia area, with severe wind chills. Here’s the prediction.

Sunday brings us the coldest day yet – which happens to be the first full day of winter.

Expect mostly sunny skies, breezy conditions and highs in the 20s [teens for the mountains]. However, it will be more in the single digits and teens for most of the day.

Monday morning you’ll need extra layers and extra time to warm up the car as temperatures range from 8 to 13 degrees. Afternoon temperatures will hover around freezing under partial skies.

Make sure your pets have a warm and dry place, preferably indoors. They are no more accustomed to the frigid Arctic air than we are.

Skies will be cloudy on Tuesday, Christmas Eve, with a brief wintry mix possible before sunrise. Highs will still be cold, peaking in the upper 30s.

Highs will reach 40 under partly sunny skies on Christmas Day on Wednesday. Hanukkah starts Wednesday evening with partly cloudy skies. Thursday is Kwanza and it will be mostly sunny and seasonal around 40 degrees.
