Pennsylvania – Cold air bites hard across the Delaware Valley this morning, stiffened by wind that cuts through coats and gloves. Sidewalks crunch underfoot. Metal railings sting bare hands. Temperatures sit in the low teens, but it feels far colder where the wind funnels between buildings and across open bridges.
According to the National Weather Service in Mount Holly, a Cold Weather Advisory remains in effect until late Sunday morning for southeast Pennsylvania, central and southern New Jersey, and parts of northern Delaware. Wind chills as low as 10 below are possible at times, creating a heightened risk of hypothermia and frostbite on exposed skin.
In Philadelphia, northwest winds continue to push Arctic air through the city. Highs struggle to reach the lower 20s today, with wind chills near or below zero for much of the morning. Any melting from brief sun can refreeze quickly after temperatures dip again, setting the stage for slick streets, icy sidewalks, and hazardous travel on I-95, I-76, and area ramps.
Sunday brings little relief. Clouds mix with sun, winds stay brisk, and highs remain in the mid-20s. Gusts near 30 mph will keep the cold sharp, especially near the river and along elevated roadways. Commuters should allow extra time and watch for black ice during early drives.
Looking ahead, the broader pattern stays locked in. The Great Lakes are nearly 50 percent frozen, helping funnel cold air east. Early next week trends drier, but temperatures remain below normal into midweek. A reinforcing cold front around Thursday could reintroduce freeze concerns down the I-95 corridor into the first full week of February.
Dress in layers, limit time outdoors, and bring pets inside. Check on neighbors who may need heat. Traveling today or Sunday? What are road conditions like where you are?
