A wintry cold front is barreling toward Louisiana, with temperatures predicted to dip below freezing as early as Monday night, ushering in what forecasters say will be a two-day freeze.

As temperatures get more extreme, hospitals, fire departments, and ambulance crews are preparing to treat more patients for heat exhaustion and heatstroke.
