Greenville, SC – Western South Carolina may see a wetter and occasionally unsettled pattern during the Thanksgiving travel window, as new federal long-range forecasts show a 33–40% probability of above-normal precipitation across the Upstate from November 23 through November 29.
According to the Climate Prediction Center’s 8–14 Day Outlook released Saturday, the region sits on the southeastern edge of a broader moisture corridor stretching across the Appalachians. While temperatures are expected to remain too warm for widespread wintry precipitation, the elevated precipitation signal could still lead to periods of steady rain and slower travel during the busiest days of the holiday period.
The Greenville–Spartanburg corridor—including Greenville, Spartanburg, Greer, and Anderson—sits squarely within the 33–40% wet-signal zone. Cold rain is the most likely outcome, though brief pockets of mixed precipitation may occur in the far northwest foothills if colder air briefly dips south.
Farther west toward the Blue Ridge foothills—Travelers Rest, Pickens, Walhalla, and communities near Caesars Head and Table Rock—the combination of elevation and nighttime cooling may support a brief rain–snow mix on mountaintops or higher ridge lines during the middle or latter portion of the week.
The I-85 corridor, one of the Southeast’s busiest Thanksgiving travel routes, may experience reduced speeds if steady rain develops during peak travel windows. Additional slowdowns are possible along I-26, US-25, and US-123, particularly during early-morning and evening hours.
Air travel delays are also possible at Greenville–Spartanburg International Airport (GSP) if widespread rain or low cloud cover arrives during peak departure periods.
Forecasters anticipate more precise timing and precipitation-type details early next week as short-range models begin to resolve individual storm systems.
