Harrisburg, PA – Imagine traveling east on Interstate 80 for Thanksgiving, crossing Pennsylvania's mountain highways when a wall of blowing snow suddenly sweeps across the roadway. Within moments, vehicles ahead disappear, brake lights fade into the whiteout and a routine holiday trip becomes a dangerous situation. It's the kind of sudden winter weather Pennsylvania motorists should prepare for as Thanksgiving approaches Thursday, Nov. 26.
According to the National Weather Service NWS , these intense bursts of snowfall, officially called snow squalls and sometimes described as "micro blizzards," can produce gusty winds, near zero visibility and rapidly deteriorating road conditions.
Unlike prolonged winter storms, snow squalls can develop quickly, leaving motorists little time to react.
Pennsylvania Highways Where Sudden Whiteouts Are a Concern Interstate 80, stretching across northern Pennsylvania through Clearfield, Centre, Clinton, Columbia and Luzerne counties, is a major travel corridor where sudden winter weather can create hazardous driving conditions.
Interstate 81 near Scranton, Wilkes Barre and Harrisburg, Interstate 79 between Pittsburgh and Erie, Interstate 90 near Lake Erie and the Pennsylvania Turnpike also face winter driving risks.
Motorists traveling through Erie, Crawford, Lackawanna, Luzerne, Monroe and Somerset counties should monitor changing forecasts, particularly when snow showers and gusty winds are possible.
Higher elevations across the Allegheny Mountains and the Pocono Mountains can experience rapidly changing visibility. Lake effect snow near Erie can also create dangerous winter driving conditions, although lake effect bands are not necessarily snow squalls.
What Happens When a Snow Squall Warning Is Issued? The NWS issues Snow Squall Warnings when dangerous snow squalls are occurring or imminent.
Warnings typically last 30 to 60 minutes and may trigger Wireless Emergency Alerts on compatible mobile phones.
Sudden whiteouts at interstate speeds can increase the risk of multivehicle crashes, particularly when motorists brake abruptly or follow too closely.
What Thanksgiving Travelers Should Do If a Snow Squall Warning is issued, the safest option is to delay travel until conditions improve .
Drivers already traveling should gradually reduce speed, increase following distance, activate low beam headlights and avoid sudden braking.
If visibility deteriorates, safely exit the highway when possible rather than stopping in an active travel lane.
Before departing, motorists should check PennDOT 511PA for road conditions and weather.gov for official forecasts and warnings from NWS offices serving Pennsylvania.
This is a Thanksgiving travel preparedness reminder, not a prediction that snow squalls will strike Pennsylvania during the holiday. Recognizing how quickly these dangerous winter conditions can develop could help motorists make safer travel decisions as Thanksgiving approaches.
