High pressure east of Florida will continue the onshore flow across the Sunshine State. However, deep tropical moisture will also continue to move into the region. Some of this tropical moisture is associated with the remnants of what was once Tropical Storm Dolly. Higher-than-normal rain chances will continue through the rest of the week, with the greatest rain chances remaining across the Florida Peninsula through Friday.

The heat will continue across the Sunshine State, making the atmosphere unstable. Deep tropical moisture will enhance shower and thunderstorm activity, especially during the afternoon. We will see partly to mostly cloudy skies at the start of each afternoon, with showers and thunderstorms developing quickly and remaining active through the late afternoon and into the early evening. Some of these thunderstorms could produce heavy rainfall in a short amount of time. This could lead to ponding of water and the risk of isolated flash flooding across the state.
For Wednesday, the flash flood risk will remain across the entire Florida Peninsula. In addition, the southern Panhandle, including the Big Bend, has a chance of isolated flash flooding. By Friday, the entire state will be under a Marginal Risk for flash flooding.
Expect the highest rainfall totals across Central and South Florida. Specifically, rainfall amounts between 5 and 7 inches are possible across parts of the interior of South Florida, extending into Southwest Florida. Areas along the I-4 corridor toward the Tampa area could also receive between 5 and 6 inches of rain over the next five days. Onshore flow will keep rainfall totals slightly lower along the east coast, with amounts generally ranging from 1 to 2.5 inches. Areas east of the I-95 corridor across East Central and Northeast Florida are expected to receive less than 1 inch of rain during the next five days…
