Will Central Florida get any rain? 

Central Florida will be mostly dry until 2 p.m., during which storms will move through the area as the sea breeze from the gulf meets the east coast sea breeze. 

Rain chances come down to around 30% with a few showers and storms on the docket during the afternoon and evening. With a ridge of high pressure working toward Florida, highs get a little boost with many spots expected to rise into the mid-90s. Feels like temps soar back into the lower to middle 100s.

By evening, around 7 p.m., some areas may get some rain, however, the chance of heavy rainfall has lessened from Saturday. 

Looking ahead

This ridge of high pressure dominates our weather pattern through the first half of the workweek, making for more heat. Temperatures surge back into the middle to upper 90s Tuesday and Wednesday. Heat Indices could top out as high as 108° or so and that's why we have Storm Team Alert for both days.

Storm Team Alert

We'll likely see Heat Advisories issued across some of Central Florida. With this area of high pressure in control, drier air will try and stifle our storm chances through Wednesday. We start to tap into a bit more moisture later in the week with rain chances back on the rise Thursday into next weekend.
