LEWISTOWN - A blast of icy weather brought winter back across Pennsylvania on Tuesday, but it may be just a little less cold in a few days.
In the Juniata Valley, the National Weather Service is calling for high temperatures to remain below freezing until Monday, with temps in the 20s for most of the week.
The thermometer stayed steadily in the teens for most of Tuesday. But as chilly as that was, it did not even approach the record cold.
According to weather.com, the record low for Jan. 22 in Lewistown is 16 degrees below zero, set in 1994. The all-time coldest recorded temperature in Lewistown is 17 below, set Jan. 21, 1994.
It isn't that abnormal for it to be really cold as mid-January is typically the chilliest part of the calendar, according the the NWS.
"It's an old-fashioned cold winter day. It's nothing record breaking, but definitely well below normal," said Rodeny Smith, a meteorologist with the NWS in Pittsburgh.
The NWS said arctic air from the northwest is causing the cold snap. Temperatures were expected to drop to zero or even 5 below for much of Pennsylvania Tuesday night causing Wednesday morning wind chills that feel like 10 or 20 below zero. Some areas could get 4 to 8 inches of snow, too, although the Juniata Valley isn't expected to see a measurable snowfall until Friday.
As for how people should deal with the bitter cold, a representative from the NWS in State College said to dress properly and to wear layers. He said people should carry emergency equipment in their cars in case of snow - including but not limited to a blanket, flashlight and a cellphone.
Elsewhere in Pennsylvania, Philadelphia is the "warm" spot in the state with temperatures of about 14 degrees Tuesday night.
Many school systems in western Pennsylvania delayed opening by two hours on Tuesday morning.
In northwestern Pennsylvania, a portion of Interstate 90 had to be closed Monday night because of a snowstorm that blanketed that region.
