Tallahassee, Florida – Triple-digit heat index values and thunderstorm chances are bearing down on North Florida this Sunday, July 20, putting residents and travelers on alert. Temperatures in Tallahassee are expected to hit 97°F by afternoon with a heat index climbing to 105°F — the kind of oppressive heat that can trigger health issues and create slick roads as storms follow.
According to the National Weather Service, a 20% chance of storms returns after 2 p.m. Sunday, as light winds give way to high humidity and scattered downpours. Anyone planning to travel on I-10 or spend extended time outdoors should hydrate frequently and monitor local radar for pop-up storm cells, which may intensify by Monday night.
By Monday, the rain risk increases significantly, with thunderstorms becoming likely after 2 p.m. and again Monday night. Highs will stay near 97°F, keeping heat concerns front and center across Leon, Gadsden, and Wakulla counties. Evening events and commutes could be impacted by strong cells and standing water.
Looking ahead, storm chances jump to 80% on both Tuesday and Wednesday with highs near 90°F. Storms are expected to persist into Thursday and Friday, but slightly cooler temps (around 92°F) may offer minor relief.
⚠️ Residents should stay weather-aware and avoid peak heat hours (2–5 p.m.), check power banks, and secure outdoor furniture in case of wind gusts.
