The stationary front that has maintained the west-to-east moisture flow and instability primarily across Central Florida will become a warm front as it is associated with an incoming low-pressure system. The transition will happen over the holiday weekend. The approaching low-pressure system, combined with typical local effects such as sea breezes and heat, will increase shower and thunderstorm activity across much of the state just in time for the holiday.
Labor Day Weekend is almost here, and you must prepare for a wetter-than-usual weekend across the Peninsula. Flash flood risk will stay mostly confined to the eastern half and the Panhandle. Please exercise caution on flooded roads and be aware of lightning. pic.twitter.com/6zr7QPxnPb

The south-southwest flow will keep the showers and thunderstorms mainly focused east of I-75 from South Florida through Central Florida. By late afternoon, the radar is likely to become more active and illuminate the western portion of the Peninsula.

While across the Panhandle, clouds will increase during the morning, with rounds of heavy showers and thunderstorms along I-10. The incoming influx of showers and storms will continue on Saturday and likely impact the first weekend of most Florida universities, as well as any first games happening in the Panhandle through North Florida.
Sunday morning will likely be a wet one across North Florida, and the heat will ignite the sea breeze, likely developing showers and thunderstorms earlier in the day across South and Central Florida.

Labor Day is likely to maintain a similar active pattern, as the front will become stagnant over the state, keeping showers and thunderstorms widespread, especially in the afternoon hours.
It's probably not the best weekend to be out at sea. Local thunderstorms may bring frequent lightning and occasionally produce strong winds. These winds could also increase the surf and winds near and offshore.
