South Florida is heating up — like your Thanksgiving leftovers — and will flirt with a high temperature record this week.

According to Miami Herald news partner CBS News Miami, Tuesday could reach a high of 85 degrees, just two degrees short of the record 87 for Dec. 2 set in 1902.

The normal high for the start of December is usually 80, the station reported.

The National Weather Service in Miami is a bit more conservative, forecasting a high of 83 Tuesday, matching Weather Underground’s hourly predictions for an 83-degree high. That steamy mark should be felt from noon to 4 p.m. Tuesday.

South Florida forecast for the days ahead

Other than a couple degrees, forecasters are in agreement with expectations for mostly sunny and breezy skies, and highs in the low 80s and lows in the low 70s through the week and weekend — except for Thursday and Friday.

After Tuesday’s slight heat-up, a cold front will sneak in by Wednesday, but it’s a timid one. Look for highs around 80 and morning lows in the upper-60s Thursday and Friday before a quick rebound to the low-80s high and low-70s lows.

There’s a 20% chance of rain in South Florida after 1 p.m. Tuesday, with wind gusts reaching 20 mph, according to the National Weather Service.

The Florida Keys should run a steady low-80s down to low-70s from Tuesday through Sunday, with just a 10% chance for showers Saturday and Sunday.

Rip tides

The sole weather warning from the weather service is a high rip current risk through 7 p.m. Tuesday for coastal beaches in Miami-Dade, Broward and Palm Beach counties. You may be tempted to swim given the warm weather.

The alert comes with the usual precautions. If you’re going to swim at the beach and feel the pull of a rip current or get caught up in one:

• Swim near a lifeguard. If caught in a rip current, relax and float. Don’t swim against the current.
• If able, swim in a direction following the shoreline.
• If unable to escape, face the shore and call or wave for help.
