Warren, PA – A strong early-season lake-effect snowstorm is intensifying across northwest Pennsylvania on Thanksgiving morning, with whiteouts and blowing snow making travel dangerous from Warren to Bradford. Rapid bursts of heavy snow are expected to continue through tonight, piling up deep totals north of Route 6 and along the higher ridges.
According to the National Weather Service in State College, a Lake Effect Snow Warning remains in effect from 1 a.m. Weather Today – Thanksgiving Day 2025 through early Saturday for Warren and McKean Counties. Forecasters expect 6 to 12 inches of snow, with locally higher amounts in persistent bands. According to meteorologists, wind gusts up to 40 mph will push snow across US-6, US-62, and rural corridors near Sheffield and Kane, creating sudden whiteouts. According to PennDOT, untreated roads will become slick within minutes of band passage and bridges may ice early.
The most hazardous period lasts through the Thursday morning and evening commute windows. Heavy snow bands will wobble and redevelop, leading to quick shifts from dry pavement to near-zero visibility. Drivers heading toward Bradford Regional Airport or crossing the Allegheny National Forest should expect significant drifting.
Residents should avoid non-essential travel. If driving is necessary, officials urge motorists to slow down, keep a winter emergency kit—flashlight, food, water—and allow extra stopping distance. Check 511PA for the latest travel restrictions as conditions may deteriorate rapidly.
Snow continues into Friday with gradual improvement Friday night.
