Bay News 9 meteorologist Brian McClure said the mix of rain showers and thunderstorms coming in from the Gulf of Mexico will not be as heavy as Thursday's downpours.
The chance of rain will decline into the weekend to about 50 percent on Saturday and between 30 and 40 percent for Sunday, McClure said, but it won't stop for long given the rainy season, during which the chance of rain generally remains anywhere between 30 and 50 percent.
As of 11 a.m. Friday, over the past 24 hours, 1.88 inches of rain were reported in downtown Tampa. In downtown St. Petersburg, rain totaled 0.88 inches.
"Rain doesn't stop here until October," McClure said. "We really have a rain chance just about every single day."
