Is Mother Nature a UM or UF football fan?

After a rainy week leading into Saturday morning’s ESPN GameDay festivities on the University of Miami campus and the big game that evening at Hard Rock Stadium, the forecast calls for more wet weather.

But it’s not as bad as was first predicted. Rain chances have halved, dropping to 30%, for Saturday and Sunday, according to the National Weather Service in Miami. There are no flash flood warnings.

The forecast ticks up to 50% on Monday, the first day of fall and the start of the Jewish holiday Rosh Hashanah at sunset.

Tuesday has a similar 50% chance for thunderstorms during the day, and dips to 30% Tuesday evening.

Preparations for ESPN’s nationally broadcast college football pregame show began Wednesday and Thursday under soaking rains on the Coral Gables campus, along UMiam’s Lakeside Patio and the Foote Green. Students perched school-colored orange umbrellas above their heads as they strolled along Lake Osceola’s bridge and darted amid puddles along the central area between the Donna E. Shalala Student Center and the Norman A. Whitten University Center Pool where the sports network’s live 9 a.m. broadcast Saturday will draw thousands to the area.

The week ahead

Saturday will be quiet in the morning, CBS Miami meteorologist Lissette Gonzalez said in her Friday morning weather broadcast. Spotty storms could develop in the afternoon. Kickoff is at 7:30 p.m. from Hard Rock Stadium in Miami gardens.

Highs should hit around 90 from Friday through the workweek, with nighttime lows in the upper-70s to 80.

“It will not feel like fall at all across South Florida since it will remain hot and humid,” Gonzalez said.

Tuesday and Wednesday rain and storm chances in Miami-Dade and Broward are at 50%, according to the weather service.
