Florida heat index forecast to soar this week; Jacksonville logs record rainfall

Heat index value rose as high as 102 degrees Saturday in southeast Florida metro areas, and warmer temperatures are yet to come during the work week, the National Weather Service said Sunday.

The heat index hit 100 Saturday afternoon at Palm Beach International Airport and Fort Lauderdale-Hollywood International, and 102 at Miami International.

Forecasters say high pressure and drier air will slide into the peninsula through mid-week, bringing actual temperatures up to as high at the mid-90s even in some of the western East Coast metro areas, with heat index values topping out as high as 107 in the Everglades.

Winds will be south to southeast, forecasters said, which may keep temperatures right at the beach and in some of the beach communities below 90. Still, Palm Beach hit 91 on Saturday near the Par 3 Golf Course, although it was 88 on the beach in Juno Beach while Virginia Key in Miami-Dade County had an almost moderate high of 86.

RECORD WATCH: Jacksonville smashed a 115-year-old single day rainfall record Saturday with 2.79 inches, beating the old mark of 2.5 inches set in 1902.

The low temperature Friday in Key West was only 85, busting the previous record-warm low of 84 degrees set in 1989.

TROPICS WATCH: The National Hurricane Center in Miami is forecasting no tropical development in the Atlantic over at least the next five days, and major forecast models show nothing of consequence forming for at least the next seven to 10 days.

Although it was an alarming start to the month — with several potent waves coming off the coast of Africa with model support for development — things have settled into the usual July lull. The only exception was minimal Tropical Storm Don, which lasted only 24 hours.

Nature generally flips a switch around the middle of August, and we’ll have to watch the models in the two weeks ahead to see if that begins to show up in the long-range forecasts.
