Jacksonville is starting Labor Day under a muggy, mostly cloudy sky, with temperatures in the mid-70s and a much better chance of rain building through the day. Showers and thunderstorms are expected to become likely from late morning into the afternoon, bringing a cooler high near 86 degrees but a serious risk of slow-moving downpours and localized flooding.
Storms Build Through The Afternoon
Rain chances rise through the morning before peaking around 70% during the early-to-mid afternoon. The strongest coverage is expected between roughly 11 a.m. and 5 p.m., when storms could bring heavy rain, frequent lightning and sudden gusty winds.
The National Weather Service Jacksonville office says the main concern is localized flooding, especially along the coast and in parts of Northeast Florida near and south of the stalled front.
