Skies were clear early Thursday after light morning fog that made for lower-than-normal visibility.
The fog was thickest in northern counties, with visibility down to one-quarter mile in Polk County, but was heavy throughout Hillsborough County as well. The Hillsborough County Sheriff's Office warned drivers around dawn to use low-beam headlights and to drive slower.
Temperatures were expected to rise into the low to mid 80s with partly cloudy skies as the fog burns off.
Though it looked to be relatively pleasant, Thursday did carry the week's highest rain chance at 20 percent, thanks to a sea breeze developing off the coast.
"That will bring us some isolated showers, maybe an isolated thunderstorm this afternoon or this evening," Bay News 9 meteorologist Juli Marquez said.
That rain chance was expected to drop off by Friday, leaving the bay area to coast into the weekend with clear skies.
