Season's first cold blast making its way to Western Pa.

Enjoy the warmer temperatures while they last: After Tuesday, the region likely won’t see temperatures above freezing for at least a week.

Pittsburgh winter will make a comeback this week, according to the National Weather Service. After daytime highs in the 50s, temperatures are expected to drop Tuesday night as a big cold front moves in, bringing clouds and light snowfall through Wednesday morning.

“We haven’t had winter for the better part of a month,” said Fred McMullen, meteorologist with the National Weather Service in Pittsburgh. The region has been experiencing a snow drought for the past month, he added. The last measurable snowfall occurred Dec. 6.

Highs will be in the low-50s on Tuesday, but then the cold blast makes its way in. Highs are forecast to be between 27 and 34 degrees from Wednesday through Sunday. NWS said wind chills Thursday morning will be in the teens.

December temperatures averaged 2.9 degrees above normal, while January 2019 temperatures so far average 9.9 degrees above normal, McMullen said.

The region saw temperatures in the low teens this time last year. Normal temperatures hover around a low of 20 degrees and a high of 36 degrees, McMullen said.
