Animals in South Florida bracing for the coldest temperatures in two years. Zoo Miami's Ron Magill says they're doing all they can to keep their furry friends warm. Afternoon highs will be in the 60's with overnight lows in the upper 40s and low 50s. Areas that fall into the 40's could see some stunted iguanas. Remember they're in a catatonic state and will come back to life once temperatures rise. The chilly weather will stay with us through Friday with a warmup back to nearly 80 degrees this weekend.
