Winter weather advisory for snow Friday

More snow is on the way for southeastern Pennsylvania as yet another winter storm is set to impact the area.

The National Weather Service has issued a winter weather advisory for the entire region from midnight Thursday to 7 p.m. Friday for 1 to 4 inches of snow.

Snowfall projections from the weather service’s Mount Holly, N.J., forecast office show most of southeastern Pennsylvania in the 3-4 inch range. However, areas to the north and west, including Berks County, are likely to see lower totals in the 2-3 inch range.

Slick road conditions are likely, and will lead to a potentially hazardous morning and evening commute, the weather service warns. With temperatures set to plummet even further after the storm late Friday night, flash freezing of untreated roads is likely.

Light snow is expected to develop late Thursday night, and will continue Friday as a low pressure system passes through the region, according to the weather service forecast discussion. Unlike the storm earlier this week that saw snow turn to rain, temperatures are expected to remain below freezing, keeping the precipitation as all snow, the forecast discussion notes.

Coming in behind the storm will be another arctic air mass that will cause low temperatures to drop from the 20s Friday night to the teens Saturday morning, according to the weather service. Wind chill values will range from single digits to as low as 10 below zero.

The deep freeze will last through the weekend, before things warm up, relatively speaking, early next week. Temperatures by Tuesday and Wednesday should be around average for this time of year.
