Columbia, SC – Sweltering heat and a rising threat of thunderstorms will converge on Columbia by late Wednesday morning, sending heat indices soaring and putting travel plans at risk. With the National Weather Service calling for storms to roll in after 11 a.m. on July 30th, residents and commuters—especially those using I-26—should brace for rapidly changing road conditions, lightning, and possible heavy downpours.
According to the latest update from the National Weather Service, Columbia faces a high near 93°F on Wednesday, but heat index values could push past 105°F. The risk for thunderstorms spikes after 11 a.m., with a 70% chance of rain and the possibility of locally heavy rainfall between a tenth and quarter of an inch. Motorists should expect sudden visibility drops and ponding on highways, including major arteries like I-26 and I-20. It’s smart to delay outdoor errands, stay hydrated, and never leave children or pets in parked vehicles—even briefly.
Communities in Lexington, Richland, and surrounding counties can expect storms to persist into Wednesday night. Power outages and minor flooding can’t be ruled out, especially in low-lying or flood-prone neighborhoods. Local schools and outdoor programs may need to adjust schedules due to lightning and downpour risks.
Looking ahead, the summer pattern continues:
- Thursday: More storms and a high near 95°F.
- Friday: Mostly sunny, still hot with storms possible late.
- Saturday: Storms remain likely; some could be strong.
- Sunday: Drier, partly sunny, highs in the low 80s.
- Monday: Thunderstorms return with highs in the upper 80s.
Stay tuned for updates as warnings may change. Another round of storms is likely this weekend—review your safety plan and check for local advisories before heading out.
