Weather for the Grand Prix of St. Petersburg

It's Florida and it's surrounded on three sides by water, so expect wildly varying conditions. As of Friday afternoon, it is forecast to be hot and humid with highs in the low 80s and a better than 50 percent chance of rain Sunday. Even in optimal conditions, St. Petersburg is described by drivers as one of the most physically demanding races on the calendar so having to wrestle the car around in the rain for even a portion of the 100 laps would present an even stiffer challenge.
