Morning daylight is a useful baseline, not a guarantee. Compare at least one earlier and one later departure along Pennsylvania Turnpike and Allegheny ridges.
A different departure may be better when the forecast includes mountain snow or freezing rain during the typical 5 hours drive.
What to check before leaving
The route crosses ridges where winter precipitation and fog can be more important than the city forecasts. Key weather factors: mountain snow, freezing rain, fog and low visibility along the corridor.
