Pittsburgh, PA – After a frigid weekend, Pittsburgh will see cold conditions continue into Monday before a notable warming trend arrives later this week.

According to the National Weather Service in Pittsburgh, Monday morning, December 15, will begin with low temperatures near 13 degrees in the city, with surrounding areas dipping into the single digits and low teens. Despite sunshine during the day, temperatures will be slow to recover, topping out near 30 degrees by Monday afternoon.

Forecasters say Monday will mark one of the colder days of the week, especially during the early commute hours when wind chills will make it feel even colder. Residents heading out early are urged to bundle up and allow extra time for warming vehicles.

While Monday remains firmly wintry, relief is on the way. The National Weather Service reports a high-confidence pattern shift midweek, bringing temperatures back above freezing. By Tuesday, overnight lows will begin to moderate, and by Wednesday, daytime highs across Pittsburgh are expected to reach the mid-30s.

The warming trend becomes more noticeable by Thursday, when highs could climb into the upper 40s, offering a sharp contrast to the early-week cold. Some nearby communities, including Wheeling and Morgantown, may briefly approach 50 degrees later in the week.

No significant precipitation is expected during the transition, allowing snow and ice from recent cold spells to gradually melt as temperatures rise. However, residents should still watch for slick spots Monday morning where refreezing may have occurred overnight.

Meteorologists say the upcoming warm-up should provide a welcome break from persistent cold, though winter conditions are far from over as December continues.

Pittsburgh residents are encouraged to stay weather-aware, dress for the cold Monday, and look ahead to improving conditions as the week progresses.
