The Brief

    • A heat advisory is in place for the majority of Central Florida from noon to 6 p.m.
    • Highs today will soar into the mid-90s for inland areas and closer to the low-90s along the Atlantic coast.
    • Some of the hottest temperatures of the summer will arrive this weekend.

ORLANDO, Fla. - Some of the hottest temperatures of the summer are expected to arrive this weekend in Central Florida, paired with near-dangerous heat indexes. A heat advisory is in place for the majority of Central Florida from noon to 6 p.m.

Here's a look at what to expect from the weather today, this weekend and looking forward to next week. 

What will the weather look like tonight?

What to expect:

A small chance of a thunderstorm or two remains Friday evening west of the I-4 corridor, but otherwise the region will stay hot and humid overnight.

The timing of the rain looks to take place later in the day than usual and will extend into the evening.

Any leftover showers will fade overnight. We stay very warm and muggy. Plan for lows in the mid-to-upper-70s.

Hot, humid weekend with minimal storm chances

What's next:

We'll see lower chances of showers and storms for both Saturday and Sunday, with only a 20-30% chance of a few isolated hit-and-miss downpours and storms. Some of the hottest temperatures of the summer will arrive on Saturday.

Saturday's high temperatures will reach the upper 90s, with heat index values soaring between 105 and 110 degrees across inland areas. 

A slight chance of isolated thunderstorms remains in Lake, Marion, Sumter, Alachua and Polk counties.

Looking ahead to Sunday, conditions will remain extremely hot, potentially even a touch hotter than Saturday. Inland highs will again push into the upper 90s, with heat index values between 105 and 110 degrees. A few isolated storms may develop in the Orlando area during the afternoon.

If you plan on heading to the beach to cool off, the water temperatures are hovering around the 80s with a moderate risk of rip currents. 

What will the weather look like next week?

Looking Ahead:

The remnants of Invest 93L look to bring more heavy rain our way into early next week. 

The system has moved inland into Louisiana and will push eastward where it could loop around and swing back down into Florida. This would bring another slug of deep tropical moisture our way for the first half of next week. This means repeated rounds of heavy rainfall are growing more likely in the Sunshine State. 

This could lead to additional inches of rainfall over areas in Central Florida that are already fairly water-logged. There are still some questions as to where exactly the heaviest rain will set up, so be sure to stay close to the forecast for more.

By Monday, scattered storms are expected to increase, but the more significant weather shift arrives Tuesday, when a surge of tropical moisture could bring widespread slow-moving showers and thunderstorms across the region. 

Forecasters warn that some areas may experience substantial rainfall totals and localized flooding, though not all communities will be affected equally.
