Temperatures dipped into the 30s and 40s across most of Central Florida early Tuesday, with wind-chill readings about 5-7 degrees cooler. A freeze warning was in effect for Marion and Sumter counties until 9 a.m., as temperatures there dipped to the 30-degree range. “Temperature readings are expected to dip into the 30s and 40s, with wind-chill readings in the 20s in some spots. “We will begin to thaw out across Central Florida by Wednesday afternoon and into the rest of the week, as highs gradually warm into the 60s and 70s,” Campos said. “The warmer weather will not last long, as another front arrives by the end of the week, dropping the highs into the 60s by the weekend.”
