A wet Grand Prix? Slight chance of rain remains in Sunday forecast

A slight chance of rain remains in the forecast for the U.S. Grand Prix on Sunday. But, if it does rain, it may only be a sprinkle. Mostly sunny skies are expected through Sunday, with highs in the 60s and lows in the 40s.

“It will be cool enough for jackets most of the time," National Weather Service forester Joe Baskin said Friday afternoon. But people should keep hydrated, he said.

Sunday could be slightly warmer, in the upper 60s, with more clouds and a slight chance of sprinkles, as a small storm system sweeps in from the Southwest and picks up moisture from the Gulf, forecasters said. But the showers it could bring would be small, forecasters said.

“From the fans’ perspective, it should be pleasant to be outside," said Bob Rose, chief meteorologist with the Lower Colorado River Authority.
