Richmond, VA – Imagine traveling south on Interstate 81 toward Roanoke for Thanksgiving when the Blue Ridge Mountains suddenly disappear behind a wall of blowing snow. Within moments, trucks and cars ahead become difficult to see, brake lights fade into the whiteout and a routine holiday trip turns dangerous. It's the kind of sudden winter weather Virginia motorists should recognize 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 drivers little time to react.
Virginia Highways Where Sudden Whiteouts Are a Concern Interstate 81, stretching through Winchester, Harrisonburg, Staunton, Roanoke and Bristol, is a major Thanksgiving travel corridor where sudden winter weather can create hazardous driving conditions.
Interstate 64 near Afton Mountain and the Blue Ridge, Interstate 77 near Fancy Gap, Interstate 66 through northern Virginia and U.S. Route 460 near Blacksburg also face winter driving risks.
Motorists traveling through Frederick, Rockingham, Augusta, Botetourt, Montgomery and Carroll counties should monitor changing forecasts, particularly when snow showers and gusty winds are possible.
Higher elevations along the Blue Ridge Mountains and Appalachian Mountains can experience rapidly changing visibility, while exposed mountain highways may become slippery as temperatures fall.
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 Virginia 511 for highway conditions and weather.gov for official forecasts and warnings from NWS offices serving Virginia.
This is a Thanksgiving travel preparedness reminder, not a prediction that snow squalls will strike Virginia during the holiday. Recognizing how quickly dangerous winter conditions can develop could help motorists make safer travel decisions as Thanksgiving approaches.
