Pittsburgh records the most snow in a single day since 2022; lake-effect snow showers continue
Lake-effect snow showers are expected throughout Western Pennsylvania Sunday, said the National Weather Service of Pittsburgh, after the winter storm warning expired at 1 p.m.
Northwest winds with gusts up to 30 mph will bring on the snow showers, which could add another inch of snow in some areas. Reduced visibility will make travel hazardous throughout the day.
Across the entire area, snowfall ranged from 4 inches up to 15 inches, with about 6 inches around Pittsburgh, NWS Pittsburgh meteorologist Andrew Kienzle said.
“It was a pretty decent snowfall event for a lot of places,” he said.
At the weather service office in Moon, the storm total from Saturday into Sunday was 5.7 inches, Kienzle said.
Of that total, 5 inches was measured on Saturday, making it the snowiest day of 2025. It was also the most snow recorded in a single day in more than three years — since March 12, 2022, when 8 inches was measured.
Yesterday’s snowfall will likely be one for our Pittsburgh record books.
❄️ By midnight we measured 5 inches, making it the snowiest day of 2025 so far and our biggest snowfall in over 3 years!
Our last big snowfall was March 12, 2022 (8 inches).

The 111-year-old record for the day, however, still stands. A total of 5.6 inches was recorded on Dec. 13 in 1914, Kienzle said.
The NWS Pittsburgh office reported at 8 a.m. Sunday 7.8 inches of snow in Unity Township, 6.5 inches in Pittsburgh’s North Side and 5.3 inches in New Kensington.
Following the heavy snow overnight, PennDOT lifted reduced speed limits and vehicle restrictions on major roadways Sunday morning.
Another shot of snow is expected north of Pittsburgh on Monday.
Because of low temperatures Monday morning, some schools have already announced delays. A complete list of delays and closures is available from TribLive news partner WTAE.
Temperatures will be rising above normal, so any precipitation later in the week will fall as rain, Kienzle said.
