Cold front, rough seas, then ‘postcard’ South Florida winter days

A cold front is forecast to move through South Florida on Wednesday as the second winter storm this month whacks the Northeast.

But following Wednesday’s showers and possible thunderstorms are “postcard South Florida dry season days,” according to the National Weather Service in Miami.

The drier, cooler air behind Wednesday’s front means temperatures Thursday will struggle to reach 70 degrees in Palm Beach County, with overnight lows in the 50s at the coast and 40s inland.

Friday highs may not reach 70 degrees, but could be slightly milder at night in the high 50s at the coast and low 50s inland.

“As the front moves out late Wednesday into Thursday, drier air will push back over the region,” NWS forecasters wrote in a morning discussion. “Not only will temperatures remain closer to seasonal averages (i.e. cooler than February, not summer-like) but clearing skies will also  make for some postcard South Florida dry season days.”

Winds will switch out of the west behind the front, but remain calm at up to 11 mph Wednesday, reducing to 10 mph Thursday.

That doesn’t mean marine and beach threats will abate.

Lifeguards closed the beach in Lake Worth on Monday as high surf washed up to the dune line.

Waves at the beach are forecast to be in the 10-foot range today, and remain up to 8 feet on Wednesday and Thursday. A high risk of rip currents is in effect through Friday.

On Monday, lifeguards from Lake Worth to Jupiter were warning people not to go in the water, and to be careful even on the beach. In Lake Worth, lifeguards strung yellow caution tape blocking entrances during high tide for fear people would get washed away by the big surf.

“We just want to make sure no one does anything foolish,” said Mathew Botts, chief of Lake Worth Ocean Rescue. “We don’t want people getting swept out to sea because they were taking a selfie and a wave gets them.”
