Clouds and light rainfall expected Thursday into Friday in South Florida from the frontal system lingering just offshore over the Atlantic, said Robert Molleda, the National Weather Service in Miami’s weather coordination meteorologist. That front will move east on Friday as the colder air swoops in.

With temperatures dropping below 50 degrees in parts of South Florida starting Thursday night, local governments are activating their cold weather emergency plans.

Clouds will remain with highs Thursday afternoon in the low 50s. The rain quickly exits Thursday evening, with clearing skies overnight. This will allow temps to tumble, with morning lows in the upper 30s.
