What weather should I check between Philadelphia and Pittsburgh?

Check mountain snow, freezing rain, and fog and low visibility along the corridor along the full Pennsylvania Turnpike and Allegheny ridges corridor. The route crosses ridges where winter precipitation and fog can be more important than the city forecasts. Refresh the forecast close to departure and verify official road information.
