Frigid temperatures and gusty winds combine Thursday to make a brutally cold day feel even frostier.
Philadelphians woke up to temperatures in the single digits Thursday morning as the mercury dropped to a low of 9 degrees -- the coldest weather this area has experienced since January 2014.
The National Weather Service has issued a wind chill advisory for a large portion of the Delaware Valley, including Berks, Bucks, Chester, Montgomery and Lehigh counties in Pennsylvania, and parts of Delaware and central New Jersey.
The advisory remains in effect until 9 a.m. as winds gusting up to 20 miles per hour will make the low temperatures feel well below zero. The wind chill will feel like -22 in the Poconos and like -10 in Philadelphia.
The cold prompted several schools, mostly in Delaware to delay their openings.
The cold weather will continue into the weekend despite sunny skies. Highs will climb into the low 30s Friday, before dipping back down into the 20s Saturday.
While we can expect some relief from chilly temps next week, wet weather is moving into the region in the 7-day forecast. A wintry mix of sleet and freezing rain is expected for Monday and could continue throughout the rest of the work week.
