Jacksonville will experience another classic midsummer day across Northeast Florida, beginning with a mix of sunshine and clouds before temperatures quickly climb through the morning.
By the early afternoon, highs are expected to reach the mid-90s, but high humidity will make it feel more like 100 to 105 degrees in many neighborhoods.
Residents planning outdoor activities should take frequent breaks, drink plenty of water, and avoid prolonged exposure during the hottest part of the afternoon.
As the afternoon sea breeze develops, scattered thunderstorms are expected to become more numerous.
While not everyone will see rain, storms that do form could become briefly strong, producing torrential downpours, frequent cloud-to-ground lightning, wind gusts between 30 and 40 mph, and reduced visibility for motorists.
The heaviest rain may cause temporary street flooding in poor drainage areas before moving out quickly.
Most storms are expected to diminish after sunset, leaving behind warm and muggy conditions overnight.
Tropical Depression Two
Tropical Depression Two has officially formed over the northeastern Gulf of Mexico, marking the Atlantic’s second tropical cyclone of the 2026 hurricane season.
Forecasters expect the system to strengthen into Tropical Storm Bertha while it tracks slowly along the northern Gulf Coast over the next couple of days.
Tropical Storm Watches have been issued for portions of the Florida Panhandle as residents prepare for heavy rain, gusty winds, and localized flooding.
