Columbia, South Carolina – A sharp rise in temperatures will push readings into the lower 90s by Thursday afternoon, bringing early-season heat that will be felt immediately across South Carolina.
According to the National Weather Service and NOAA’s Climate Prediction Center, South Carolina is in an 80 to 90 percent probability zone for above-normal temperatures from April 16 through April 20. A strong heat dome will dominate the Southeast, limiting cloud development and shutting down widespread rainfall.
In Columbia and across Richland and Lexington counties, highs are expected to reach 89 to 92°F between 2 p.m. and 6 p.m., with overnight lows staying in the upper 60s. Along the I-20 and I-26 corridors, dry vegetation will become more susceptible to ignition, especially during peak afternoon heating.
Upstate cities including Greenville and Spartanburg will climb into the upper 80s to near 90°F, while coastal areas such as Charleston and Myrtle Beach will see highs in the mid to upper 80s with a slight sea breeze influence. Despite that coastal moderation, rainfall will remain limited statewide.
The precipitation outlook shows a 33 to 50 percent chance of below-normal rainfall, reinforcing dry conditions and increasing wildfire risk. Forestry officials may begin evaluating burn restrictions if conditions persist through the weekend.
Residents are urged to avoid outdoor burning, stay hydrated, and limit activity during peak heat hours. Drivers along I-95 and I-77 should be mindful of heat impacts on vehicles, especially during long afternoon commutes.
The most intense heat is expected April 18 through April 20, when a “much above normal” zone settles over the Southeast. Additional advisories are possible as hot, dry conditions continue into early next week.
