Columbia, S.C. – South Carolina is bracing for triple-digit heat on Tuesday, June 24, as temperatures soar and dangerous heat index values return. The National Weather Service has issued a warning for the Columbia area, where the heat index could climb as high as 106°F by the afternoon. Travelers along I-26 are also urged to be cautious as the extreme heat continues.
What to Expect on Tuesday
Temperatures in Columbia are expected to hit 99°F on Tuesday, but with high humidity levels, the heat index will make it feel like 106°F. The winds will remain light, providing little relief from the scorching heat. Prolonged exposure to such high temperatures significantly increases the risk of heat-related illnesses, especially for outdoor workers, the elderly, and other vulnerable groups.
Weather Conditions Throughout the Day
The day will begin mostly sunny, but clouds will begin to build later in the day. While no rain is expected on Tuesday, humidity levels will climb, making outdoor activities dangerous. The South Carolina Department of Health and Environmental Control advises people to stay hydrated, avoid strenuous activities during peak heat hours, and check on elderly neighbors who may be more susceptible to the heat.
Relief in Sight, but With Storms
By Wednesday, there is a chance for some relief as scattered thunderstorms are expected to develop after 2 p.m. in Columbia. While the rain will bring some cooler temperatures, instability in the atmosphere could lead to sudden thunderstorms, especially along major travel routes like I-20 and I-26. The storms will bring light rainfall amounts, with new rain between a tenth and a quarter inch in Columbia.
The storm chances will continue into Thursday and Friday, with further thunderstorms possible as the week progresses.
Travel Advisory
Travelers should be alert for slick roads and sudden downpours as midweek storms affect the I-20 and I-26 corridors. The storms could impact driving conditions, so plan accordingly and stay updated on weather alerts.
