Greenville, SC – Imagine heading north from Greenville toward the Blue Ridge Mountains for Thanksgiving when a sudden burst of heavy snow sweeps across the highway. The road ahead becomes difficult to see, brake lights appear through blowing snow and a familiar mountain drive turns hazardous within moments. Although uncommon in South Carolina, this type of rapidly changing winter weather is worth understanding 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, sharply reduced visibility and rapidly deteriorating road conditions.
Unlike prolonged winter storms, snow squalls are short lived and can develop quickly, leaving motorists little time to react.
South Carolina Highways Where Winter Weather Is a Concern Interstate 85 through Greenville, Spartanburg and Anderson is a major Thanksgiving travel corridor where snow or ice can create hazardous driving conditions when winter weather develops.
Interstate 26 near Landrum and the North Carolina border, U.S. Highway 25 north of Travelers Rest and U.S. Highway 276 toward Caesars Head also face potential winter driving hazards.
Motorists traveling through Greenville, Spartanburg, Pickens and Oconee counties should monitor forecasts, particularly when cold air, snow showers and gusty winds are possible.
Higher elevations near the Blue Ridge Escarpment are more susceptible to snowfall and freezing conditions than much of South Carolina.
What Happens When a Snow Squall Warning Is Issued? The NWS issues Snow Squall Warnings when dangerous snow squalls are occurring or imminent.
These warnings generally last 30 to 60 minutes and may trigger Wireless Emergency Alerts on compatible mobile phones.
Although snow squalls are relatively uncommon in South Carolina, sudden snowfall and reduced visibility can create serious risks for drivers unfamiliar with winter road conditions.
What Thanksgiving Travelers Should Do If a Snow Squall Warning is issued along a planned route, 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 South Carolina 511 for highway conditions and NWS Greenville Spartanburg for official forecasts and warnings.
This is a Thanksgiving travel preparedness reminder, not a prediction that snow squalls will strike South Carolina during the holiday. While widespread snow squalls are unlikely in a typical South Carolina November, recognizing sudden winter hazards could help travelers make safer decisions when heading into the Upstate mountains or neighboring North Carolina.
