Conditions were colder north of Tampa Bay -- Citrus and Hernando counties are under freeze warnings -- but forecasters advised residents to limit time outdoors and to dress in warm layers of clothing. They also should bring pets inside.
Wednesday in Bradenton, the Weather Service says skies should be sunny with a high of 62 and north-northeast winds of 11 to 16 mph, with gusts as high as 22 mph. Wednesday night's low could dip to 47.
Thursday should be sunny, with a high of 71, according to the Weather Service. The next chance of rain is forecast for Saturday evening.
"The good news is that we will see a lot more sunshine for Wednesday which will help to moderate things just a bit," McClure said. "The real warming trend will come Friday into the weekend when high temperatures get back to normal."
