South Carolina – Bright sun and warm air are pushing temperatures toward a summer-like feel this afternoon, but a quick shift arrives within the next 24 hours that could catch drivers and outdoor plans off guard.
According to the National Weather Service, highs are climbing to around 90°F today across the Upstate, including Spartanburg, before a weak system introduces a 30% chance of showers by Sunday, mainly before early afternoon. Winds could gust near 29 mph during this transition, especially along I-85 and surrounding corridors.
Across Greenville, Spartanburg, and Gaffney, the story changes quickly. Today’s dry pavement and clear skies give way to increasing clouds and brief, light rain potential by Sunday morning. While rainfall totals stay light, isolated slick spots could develop during early travel hours. Plan ahead if heading out.
Temperatures also take a noticeable dip. After near 90°F warmth, highs fall back to the upper 60s Sunday, then settle into the low 70s Monday. That cooler air will feel sharp after the heat, especially with a light breeze.
By Sunday night, skies clear and temperatures drop into the mid-40s across parts of the Upstate. Early Monday morning could feel brisk, especially in rural areas and valleys.
The good news is a steady rebound. Sunshine dominates early next week, with highs returning to the 70s and eventually climbing into the 80s by midweek, signaling a broader spring warm-up trend.
