Pittsburgh, PA – Lake-effect snow is expected to create slick road conditions across northwest Pennsylvania this evening, potentially impacting travel between 5 p.m. and 11 p.m.
According to the National Weather Service in Pittsburgh, a Winter Weather Advisory has been issued for Mercer, Venango, and Forest counties as colder air moves in behind a frontal system. Forecast models indicate the development of narrow lake-effect snow bands, which could lead to localized higher snowfall totals within the advisory area.
Snow is expected to begin during the early evening hours, with the most likely impacts occurring during the evening commute window. While overall snowfall amounts are generally forecast in the 1 to 3 inch range, the National Weather Service notes that some narrow bands could briefly produce higher totals, especially in areas where bands remain stationary.
Forecasters emphasized that even light snowfall may result in slick or icy roads, as falling temperatures can quickly freeze melted snow on pavement. Motorists are urged to use caution, reduce speeds, and allow extra travel time.
The advisory highlights uncertainty in band placement and duration, meaning conditions may vary significantly over short distances. The National Weather Service warned that short-notice advisories or warnings could be issued if lake-effect snow bands intensify or persist longer than expected.
This weather pattern may be especially relevant for evening commuters, delivery drivers, and shift workers traveling across rural highways and secondary roads in northwest Pennsylvania.
Drivers are encouraged to monitor local forecasts and road conditions through the evening hours and be prepared for rapidly changing visibility and traction.
