Behind the frontal boundary, temperatures will immediately and rapidly plummet this afternoon. Many locations will fall from near 70° to mid 40’s in 1-2 hours! Gusty winds will also kick up to yield wind chills in the 30’s across much of PA by 8 p.m. this evening.

Lows will fall into the 30’s region-wide tonight and the combination of blustery conditions will prompt wind chills in the 20’s across the area by Thursday morning, and wind chills in the teens are likely in the Poconos and Lehigh Valley. A freeze warning will go into effect overnight through 9 a.m. Thursday. High temperature struggle to low 50’s Thursday afternoon, and with wind gusts to 40 mph, it will feel like 30’s and low 40’s almost all day long.
