PHILADELPHIA (CBS) — An arctic cold front has moved through the Delaware Valley Monday morning ending the rain showers.
Temperatures early Monday morning reached the low 60s in some locations. Now that the front has passed, strong westerly winds will transport the cold arctic air mass into the region Monday night.
Temperatures will continue to fall through the 30s in the evening, then reaching the upper teens by around midnight and bottoming out in the single digits by daybreak. Daytime temperatures Tuesday will struggle to get into the low teens Tuesday afternoon.
Dangerous wind chills are also expected to develop late Monday night. A wind chill advisory will go into effect at 1 a.m. Tuesday for the Delaware Valley. Sustained winds of 20-25 mph with gusts to 40 mph will bring wind chill values into the teens and single digits Monday evening. Then down to -10 to -15 degrees by Tuesday morning and will remain below zero through the day on Tuesday. Wind chill values in the Lehigh Valley Poconos could reach -20 to -30 degrees on Tuesday morning.
With temperatures dropping into the single digits Tuesday, some record lows will be challenged or broken.
Here are some record lows for Tuesday:
Allentown: -4 (1942)
Atlantic City: 4 (1884)
Mt. Pocono: -5 (1988)
Philadelphia: 7 (1988)
Reading: 6 (1998)
Trenton: 6 (1912)
Wilmington: 10 (1988)
This won’t be a long lasting arctic outbreak since the weather pattern remains progressive. Temperatures will be back in the 20s on Wednesday, 30s on Thursday and around 50 by the weekend.
Stay warm everyone!
