Wednesday and Thursday will be hot and humid as a southerly flow of air on the west side of a high pressure ridge dominates the Florida Peninsula. As a cold front approaches from the north, the pressure gradient will tighten and produce breezy conditions on Thursday. Gusts around 25 mph can be expected at times.
The cold front will move through early Friday morning, and it may produce a few light showers. The timing of any showers still appears to be before any on-track action starts, so there should be no impact.
Cooler and drier air will build in on the heels of a northerly wind, and the main event on Saturday should have perfect weather.
The next planned forecast update will be posted on Thursday, unless there is a major change needed tomorrow.
