South Florida Weather Forecast, Triple Digit Heat Index, Weekend Rain


“Hot enough for you?” the old idiom goes.

It’s a question that might well be asked by your unoriginal, but well-meaning friends over the weekend in South Florida. That’s because the heat index – the combination of temperature and humidity and what it makes you really feel – reached 107 degrees Wednesday afternoon and remains in the triple digits for most of the week, according to the National Weather Service in Miami.

But don’t expect any heat advisories just yet. It’s warm enough for all of us — including the weather service folks who also live outdoors — but for one degree it doesn’t quite hit the threshold that triggers an advisory.

Weather Services meteorologist Will Redman told the Miami Herald last week that the threshold is a heat index of 108.

Along with seasonal highs and steady temperature readings around 90 degrees through the start of the next work week, South Florida is looking at an increased chance of showers and thunderstorms.

According to CBS4 meteorologist Lissette Gonzalez, “the weekend is going to be wetter.”

Scattered in numerous showers and thunderstorms are expected to develop noon through evening Wednesday through Sunday with a 60% chance.

Some of those storms could bring heavy downpours, wind gusts exceeding 40 mph and frequent lightning, the weather service said in its hazardous weather forecast.

There is also a high risk of rip currents returning to east coast beaches over the weekend.

Similar forecast for the Florida Keys as well, except the chance of rain and storms are a bit lower, with Saturday’s 50% chance appearing to be the wettest day.

The National Hurricane Center has reduced the chances of development of a disturbance extending from the Florida Panhandle west-southwest along the northern Gulf Coast to zero percent.

Since Wednesday’s 8 a.m. advisory, this trough has been producing showers and scattered thunderstorms over the northern Gulf of Mexico and adjacent land areas. The system is expected to drift north over land for the next few days, stifling its chances of development.

But heavy rains could still promote flash flooding along parts of the northern Gulf Coast from Louisiana to the Florida Panhandle into the weekend, the hurricane center said.

There is an 80% chance of thunderstorms and showers in Tallahassee Thursday and Friday and the chance of rain remains high at 70% Saturday and Sunday.
