South Florida’s scorching temps make for a weekend record-breaker. Here’s what’s ahead.

A record-breaking heat wave has most of South Florida wilting — and wondering when it will end.

There’s no major cooldown ahead just yet, but temperatures will drop a touch on Monday, said George Rizzuto, a meteorologist at the Miami office of the National Weather Service.

Monday’s heat index will hit around 100 degrees, down from Sunday’s “feels-like” temps of 105 to 110 degrees.

“It will still be hot, but not as oppressively hot as it has been this weekend,” Rizzuto said. “For Tuesday and Wednesday you can expect indices in the upper 90s.”

Next Saturday, the heat index will rise back up to 100 degrees, according to the forecast.

“Not too much of a break in the heat,” Rizzuto said.

Hot and humid conditions continued Sunday, with temperatures hitting to the low- to mid-90s and the peak heat index ranging from 105 to 110 degrees.

Both Broward and Miami-Dade counties were under a heat advisory until 6 p.m. Sunday.

The maximum heat index forecast for Sunday afternoon was 105 degrees in Fort Lauderdale; 106 degrees in West Palm Beach; and 109 degrees in Miami and Homestead.

The heat index is a measure of how hot it really feels when relative humidity is factored in with the actual air temperature.

“If you’re spending any time outside (Sunday), it is imperative that you are hydrating nearly constantly and take breaks from the direct sun,” the National Weather Service warned on X, formerly known as Twitter.

Saturday’s blistering heat was a record-breaker.

“West Palm Beach set a new record with a temp of 97,” Rizzuto said. “Their old record was 94, set in 1922. It beat it by 3 degrees. Fort Lauderdale tied their maximum temperature record of 96. That was set back in 2008.”

The region’s nightly lows did not drop much below 80 degrees Friday night into Saturday morning, Rizzuto said.

So now we have new records for minimum lows.

The new record low for West Palm Beach is now 80 degrees. That beat an old record of 78 degrees set back in 2003.

Fort Lauderdale set a new record low of 80 degrees. The previous record low was 77 degrees, set in 2015.

Miami set a new minimum low of 81 degrees. The old record of 79 degrees was set back in 1935.

Strong to severe storms were possible Sunday afternoon, according to meteorologists in Miami.

“Primary hazards will be large hail and damaging wind gusts but a tornado or two can’t be ruled out,” the National Weather Service’s Miami office said in its Sunday advisory.

Showers and thunderstorms might roll into Broward’s eastern metro areas late afternoon Sunday and into the evening, Rizzuto said.

But Palm Beach County’s eastern metro areas and Lake Okeechobee region are at a higher risk for thunderstorms Sunday afternoon and evening.

“I can’t rule out a strong cell for Miami-Dade County and its eastern metro areas,” Rizzuto said.

An isolated tornado might also be in the cards, he added.

“We can’t rule out hail either,” Rizzuto said. “The hail risk is more maximized toward northern Palm Beach County and the Lake Okeechobee area. We have a low pressure system pushing toward the east. That could allow raindrops to stay frozen in the upper atmosphere. But sometimes the hail melts before it gets to the ground.”
