Record cold Sunday in West Palm Beach, unusually cold again tonight

Clouds, rain and chilly temperatures plagued South Florida Sunday, tying a record cold high set 62 years ago.

Sunday’s high temperature at Palm Beach International Airport reached just 59 degrees.

That’s 16 degrees below normal and tied the record-cold daytime high set in 1955.

Naples and Fort Lauderdale also experienced record cold on Sunday. At just 60 degrees, Naples broke the record-cold high of 64 set in 2007. Fort Lauderdale tied its record of 62 degrees set in 1978.

A combination of a disintegrating front near the Florida Straits, with a deep dip in the jet stream high in the atmosphere is to blame for the cold, wet day.

While a dry front pushing through this morning should mean clearing skies today and highs reaching near 70 degrees, tonight will bring another blast of cold.

With no clouds radiating infrared radiation toward the surface overnight, the ground will easily lose its daytime heat leading to much cooler temperatures.

National Weather Service forecasters in Miami are calling for overnight lows in the upper 30s across north-central Palm Beach County and around 50 degrees along the coast.

“A reinforcing shot of chilly air behind a weak front may allow wind chill temperatures to drop from the mid to upper-30s across areas west of Lake Okeechobee to mid-40s to near 50 across the southeast coast and 40s elsewhere across interior South Florida,” forecasters wrote in a hazardous weather outlook this morning.

The official forecast for West Palm Beach overnight is 46 degrees. Jupiter could see 49 degrees, with Wellington falling to 46 degrees. If those temperatures verify, it could be the coldest night of the season for many areas.

It will likely be the coldest night of the year. So far this month, the coldest temperature West Palm Beach has experienced is 51 degrees on Jan. 8.

The normal overnight low for late January is 57 degrees.
