'Bitter' Cold Coming Early This Week, Forecasters Predict

An Arctic front will bring ”bitter” cold to the region this week, forecasters say. In response to the dropping temperatures, at least two Philadelphia area counties have declared a “Code Blue” through Thursday morning.

Daytime temperatures in the Philadelphia region will be in the mid-20s on Monday and Tuesday. Overnight temperatures will be in the teens Monday into Tuesday, according to the National Weather Service.

“Blustery winds will worsen the situation,” Accuweather predicts.

The Code Blue declaration in Montgomery County goes from 9 p.m. Sunday through 9 a.m. Thursday. A Code Blue in Bucks County extends from Sunday night through 7 a.m. Thursday.
