Charlotte, NC – Scorching heat and afternoon thunderstorms will slam into the Carolinas on Wednesday, sparking a Summer Weather Alert across the Piedmont and Upstate regions. Heat index values could soar as high as 108°F by 2 p.m., prompting advisories and urgent safety reminders for residents and travelers from Charlotte to Greenville.
According to the National Weather Service in Greenville-Spartanburg, a Heat Advisory remains in effect from 12 p.m. to 8 p.m. EDT Wednesday across northeast Georgia, western North Carolina, and the South Carolina Upstate.

Cities at risk include: Charlotte, Concord, Gastonia, Rock Hill, Greenville, Spartanburg, and surrounding counties. Air conditioning, hydration, and avoiding mid-day outdoor activity are critical. Children and pets should never be left in vehicles, even briefly.
