It is winter, and midwinter to be specific, but it is absolutely imperative that the bitter cold be treated with respect. If you are caught outdoors unprepared frostbite will become a serious threat through the day as wind chills drop to the -20 to -30 range.

Buckle up South Florida, as the rollercoaster ride is about to begin.

A warmer Wednesday is expected across South Florida after we woke up with temperatures in the mid- to upper 50s rather than the frigid 40s and 30s that we experienced recently.

Expect a brief blast of cold air Friday and Saturday morning before milder weather returns next week.
