Weather Authority: Weekend storm to bring snow, rain and flash freeze

A strong winter storm system will bring snow, rain and a flash freeze to our area over the weekend followed by arctic air.

Pennsylvania and New Jersey governors have declared a State of Emergency in anticipation of part two of a roller coaster of winter weather.

A Winter Storm Watch has been issued for parts of the area (mostly north and west), including Berks, Lehigh and Northampton counties, from 1 p.m. Saturday until 4 p.m. Sunday. The heaviest snowfall is expected over northern portions of our area.

Saturday Night through Sunday Morning

System number two won't reach the area until Saturday between 6 p.m. and 9 p.m., but it will be packing much more moisture.

It should start as all snow or a wintry mix up north before changing to heavy rain late Saturday night through Sunday morning.

For Philadelphia, it will be a mainy rain event. The Lehigh Valley could see between 3-6 inches of snow, while the Poconos is expected to see between 6-12 inches.

Once the precipitation stops, we won't be out of the woods. Arctic air will rush in Sunday and could cause flash freezing as temperatures plunge and wind chills fall below zero degrees between 11 a.m. and 3 p.m. Sunday.

Freezing rain will also be a concern, with as much as a .10 to .25 inches of ice far north and west.

Monday Morning Freeze

The final part of our wintry stretch will come Sunday afternoon into Monday as temperatures fall from the 40s into the teens overnight.

Monday's high is only expected to reach 18 degrees. Blustery winds will keep wind chills in the single digits.
