Pittsburgh, Pennsylvania — Another round of accumulating snow and bitter cold is expected to impact western Pennsylvania late this week, but forecasters say signs are emerging of a possible warm-up by the middle of next week.
According to the National Weather Service Pittsburgh, snow is expected to return Friday, followed by a sharply colder air mass settling over the region through the weekend. Forecast probabilities show a 75 to 100 percent chance of sub-freezing high temperatures Saturday and Sunday across communities along Interstate 79, Interstate 376, and U.S. Route 30, including Pittsburgh, Latrobe, and Indiana.
By early next week, conditions remain cold, but long-range outlooks indicate a gradual shift. The probability of daytime highs exceeding 40 degrees increases beginning Tuesday, with chances rising to 50 to 75 percent by Wednesday and Thursday in parts of Allegheny, Washington, and Westmoreland counties. Areas south and east of Pittsburgh may see the warm-up arrive slightly sooner.
The forecast reflects a transition as the cold pattern weakens and the next storm system approaches, allowing milder air to push northward. While this does not guarantee a sustained warm period, it does suggest a break from persistent below-freezing temperatures.
For commuters and students traveling along I-79, I-70, and I-376, winter driving conditions are most likely through the weekend, with potential improvement during the midweek period if the warmer trend materializes.
Residents are encouraged to remain weather-aware, particularly with snow and cold impacts Friday through Sunday, and to monitor updates from weather.gov/pbz as confidence in next week’s temperature trend improves.
