PHILADELPHIA (CBS) — After a frigid morning with teenage lows and some numbers in the north and west, highs bounced back to the 1940s across much of the region on Wednesday.
The temperature in Philadelphia finally rose above freezing at 9 a.m. Wednesday after a 42-hour period below freezing.
Highs will be slightly above average on Thursday as the day will serve as calm before the bitter cold returns and a powerful storm arrives. An arctic cold front will come in on Friday, after which the wind will blow and the temperature will plummet. By Friday night, chills are falling into the teens.
Expect a frigid start to the weekend with sub-zero chills likely across the region. Dangerous cold will develop in the Poconos with chills as cold minus-30 degrees from late Friday night through early Saturday.
In these conditions, frostbite and hypothermia are possible within minutes without the right clothing. The shivers in the wind will remain below zero in the mountains and into the low teens and single digits in the Delaware Valley Saturday afternoon.
Then a large, powerful and dynamic storm system appears to affect the region Sunday evening through Martin Luther King Day on Monday. Current data points to a measurable snow change in rain for the city and nearby suburbs, all snow far north and west, and primarily all rain on the Jersey Shore.
Intense gusts of wind are likely to appear Sunday evening, and with possible simultaneous snowfall, power outages could be possible or widespread. Stay tuned for the evolving forecast.
