Heatwave Ahead: Storms May Arrive This Evening

Columbia, South Carolina, USASunday, July 19, 2026

A sweltering day is expected to continue across the region, with temperatures climbing into triple digits. By late afternoon, a weak cold front from the north will push toward the Midlands, raising the possibility of thunderstorms. The forecast warns that some storms could become strong or even severe, bringing dangerous wind gusts.

Risk Levels
• Yellow – 2‑out‑of‑5 likelihood of serious storms
• Green – Marginal risk

While most places may stay dry, a few pockets are highlighted as having a slight chance of severe weather. Meteorologists emphasize that the main danger will be high winds rather than hail or tornadoes.

The heat index today could reach about 104 °F, making it feel even hotter. Residents are advised to stay hydrated and avoid outdoor activities during peak heat hours.

Looking ahead, the best chances for rainfall are scheduled for midweek. Tropical moisture from the Gulf will join a passing front, increasing the likelihood of heavy showers on Wednesday and Thursday. These storms could bring significant rainfall totals.
