PITTSBURGH — Western Pennsylvania and Northern West Virginia are experiencing a significant drop in temperatures as a cold front moves through the region. The cold air began settling in early Saturday morning, causing temperatures to reach their peak just after midnight. This cold blast is following a departing area of low pressure, which is bringing lake-effect snow and making conditions even chillier.
The lake-effect snow, caused by cold air moving over the relatively warmer waters of Lake Erie and Lake Superior, is expected to create a snow band stretching from Cleveland to Pittsburgh. While the snow won’t be heavy across the entire area, some locations could see a few inches of snow, while others might not get much at all. Reduced visibility is also a concern, especially in areas where snow bands are present. Drivers should be extra cautious and prepared for sudden changes in road conditions.
The snow bands are expected to hit between 8 a.m. and 9 p.m. today. The snowfall will likely be most intense during the early and mid-afternoon, with coverage diminishing as the day progresses. By late afternoon and into the evening, the snow should begin to taper off, leaving behind a cold but clearer sky.
As the night settles in, high pressure is expected to move into the region, bringing clearing skies and calmer conditions. Sunday morning will be cold, with temperatures expected to drop into the teens, especially in rural areas and higher elevations. Winds will be light, but the chill will make it feel even colder.
Monday morning will also be cold, but by the afternoon, temperatures will begin to warm up slightly. Highs are expected to reach the low 40s as warm air starts to move in from the southeast. This shift in air will bring a break from the cold, and the weather will feel more mild compared to the weekend’s frigid conditions.
However, the warmer air won’t last long. By Monday evening, moisture from the atmosphere will start to return, bringing the possibility of more rain and snow showers. This will continue into Tuesday morning, with brief but scattered snow showers expected, especially in the northern and western parts of the region.
Looking ahead to Christmas Day, high pressure will settle in, leading to generally calm and mild weather. It’s expected to be a nice, quiet day with partly cloudy skies and temperatures in the low 40s. While there may be some fog in the morning, conditions will improve as the day goes on, making it a pleasant day for holiday festivities.
After Christmas, above-average temperatures are expected to continue into the end of the year. While the weather will remain mild, there is a good chance of rain returning by the end of the week, with another weather system moving in.
Residents of Western Pennsylvania should keep an eye on the weather, as conditions could change quickly with lake-effect snow bands and the fluctuating temperatures. If you’re planning to travel, especially along the I-80 corridor and other highways, make sure to allow for extra time and be prepared for any unexpected weather changes.
