Pittsburgh, Pennsylvania – Quiet weather Saturday will give residents across western Pennsylvania a chance to prepare before the threat of severe thunderstorms increases late Sunday and becomes more widespread Monday. While most of Saturday will stay dry with highs in the upper 70s to lower 80s, forecasters are tracking two rounds of potentially strong storms that could impact travel and outdoor plans.
According to the National Weather Service in Pittsburgh, isolated showers and a thunderstorm are possible Saturday, but most locations will remain dry. A Marginal Risk (Level 1 of 5) for severe thunderstorms develops Sunday between 2 p.m. and 10 p.m., primarily across eastern Ohio, where damaging wind gusts are the primary concern.
The greater threat arrives Monday afternoon through Monday night, when much of western Pennsylvania, eastern Ohio, and northern West Virginia falls under a Slight Risk (Level 2 of 5) for severe thunderstorms. Forecasters say storms could produce damaging winds, large hail, isolated tornadoes, and locally heavy rainfall capable of causing flash flooding. While confidence in exact timing remains low, the potential for severe weather is higher than Sunday’s outlook.
Communities including Pittsburgh, Butler, Washington, New Castle, Latrobe, Wheeling, New Philadelphia, Zanesville, Morgantown, and surrounding areas should closely monitor updated forecasts. Travelers on Interstates 70, 76, 79, 80, and the Pennsylvania Turnpike could encounter rapidly changing conditions if storms develop during the afternoon or evening commute.
Residents are encouraged to review severe weather safety plans now, ensure mobile devices can receive emergency alerts, and have multiple ways to receive warnings if storms intensify. Secure outdoor furniture and other loose items before Monday, and move indoors immediately if a warning is issued.
