A surge of tropical moisture, sea breezes from both coasts, and approaching upper-level disturbance are likely to stir up a stormy finish to the hurricane-abbreviated work week in North Florida. Showers and thunderstorms could be numerous, slow-moving, and strong in many inland areas by late afternoon. The rain might also last for several hours in some spots, possibly aggravating ongoing flooding caused by Hurricane Irma earlier in the week.

Timing and location of the storms

The first cells of the day are likely to fire along the Gulf sea breeze as it pushes inland from the Nature Coast just after lunchtime. When the Atlantic sea breeze arrives, likely after 3 or 4 pm, showers and thunderstorms will become more numerous and much stronger. This is most likely to occur near or between the I-75 and US 301 corridors by early evening. The strongest cells will be capable of producing wind gusts to 60 mph and rainfall rates of two to three inches per hour. Since upper-level winds are somewhat neutral (only slightly more dominant from the east), the cells are likely to take on a slow and erratic motion to the west-southwest. It is possible that some rain showers linger into the late evening hours, especially near and west of the I-75 corridor.
