South Carolina – Afternoon thunderstorms could snarl traffic on I-26 and local Columbia roads Wednesday as a new round of summer storms rolls in. Residents should expect sudden downpours and potential flash flooding starting after noon, making midweek commutes riskier and outdoor plans uncertain.
According to the National Weather Service, showers and thunderstorms are likely between 2 p.m. and 8 p.m. Wednesday, July 16. Rainfall could be locally heavy, with brief gusty winds and lightning possible. While rain totals are expected to stay under a tenth of an inch for most, some neighborhoods may see higher amounts beneath stronger storms. Temperatures will climb to 92°F with sticky humidity, adding to the discomfort and driving up the heat index.
Drivers along I-26, I-20, and US-1 should allow extra travel time and watch for ponding on roads. Afternoon outdoor events and sports could see delays or cancellations. If thunder roars, head indoors until the storms move through. Remember to charge phones and review severe weather alerts as a precaution.
Looking ahead, rain chances dip to 40% on Thursday with storms possible after 11 a.m., followed by a return to sunshine on Friday. Highs reach 94°F Thursday and Friday, with more storms possible Friday night. The weekend turns even hotter, nearing 97°F Saturday and Sunday, with more scattered storms—classic July weather for the Midlands.
Warnings remain in effect through Friday, with more advisories possible if storm activity ramps up. Stay tuned for updates from the NWS and local emergency officials.
