Weather alert: South Florida dips into the 50s

Cold fronts are relative.

If you’re in the northeastern U.S., it means snow days and frostbite warnings. In South Florida, temperatures dipped into the 50s early Thursday morning.

But the drop won’t last long, according to the National Weather Service. The lows on Thursday night will be in the 60s. And by the weekend, highs will rise again to the 70s and 80s, with thunderstorms in the forecast.

On the water, a rip current advisory is in effect from 7 a.m. Thursday until 1 a.m. Friday. Winds of 10 to 10 mph are expected.

In North Florida, temperatures plunged to the 20s Thursday morning.

But the serious chill is being felt across the northeastern U.S, where temperatures are falling into the single digits and snowfall is expected. Some areas in the Midwest received a foot of snow, with wind chills falling below 0.
