South Carolina starts the morning under a blanket of gray clouds, with mild air and dry pavement for now. That changes quickly as moisture builds across the Upstate, setting the stage for a wetter and slower-moving day.
According to the National Weather Service, Spartanburg, Greenville, Greer, and Gaffney will see a slight chance of showers early, with rain becoming more likely after 4 p.m. today. The initial impact window runs from 5 p.m. to 9 p.m., when light rain may begin to create slick roads along I-85 and I-26. Low-lying intersections and underpasses could see water begin pooling within minutes as rainfall develops.
This is part of a broader system pushing east from the Lower Mississippi Valley, drawing Gulf moisture into the Southeast and supporting multiple rounds of showers and storms.
Conditions intensify Saturday, when rain chances climb to 80% after 2 p.m. The peak impact window targets 2 p.m. to 7 p.m., when steady rain and patchy fog may reduce visibility and slow weekend travel. While severe storms are limited, an isolated thunderstorm could produce brief gusty winds or small hail, adding to disruptions.
Rain tapers Saturday night, with clearing skies arriving late. Sunshine returns Sunday with highs near 69°F, followed by a warming trend into the mid to upper 70s by Monday and near 80°F Tuesday. Early next week signals a more consistent spring pattern.
Plan for slower travel this evening and especially Saturday afternoon, avoid water-covered roads, and allow extra time on major highways as rain spreads across the Spartanburg area.
