Daytime temperatures are still expected to reach near 80 degrees, but are expected to be slightly below the normal of 81 degrees for this time of year. The normal low is 66 degrees.

Unlike last weekend’s front, the one reaching South Florida tomorrow is expected to be mostly dry with only a few showers running along it’s boundary.

The cold front is expected to near South Florida early Thursday morning.

The cold front is expected to moving through Palm Beach County around 8 a.m. Thursday.

“The main impact with the frontal passage will be low temperatures falling into the 50s across much of South Florida outside of portions of the east coast metro Thursday and Friday night,” forecasters in Miami wrote. “Friday night will be the coldest night, with lows possibly reaching as low as 60 in the east metro areas.”

Helping the cold front along is a robust dip in the jet stream, which is screaming overhead at about 30,000 feet and pushing deep into the southeast.

Jet stream forecast for 2 a.m. Thursday

“High pressure will dominate the long term period with dry and pleasant weather expected over the weekend and into early next week,” forecasters in Miami wrote.

A high risk of rip currents will continue at least through today as a northeasterly swell from the western Atlantic builds off Palm Beach County.

Swells could be as high as six feet with breaking waves reaching seven feet. A high surf advisory is being considered. The bigger swells are coming this way from a massive low spinning away from the northeast U.S.
