.DISCUSSION...
Issued at 244 PM EDT Sun May 24 2026

Our southeasterly flow will remain in place for Sunday.
This will once again favor mainly evening storms along the seabreeze
boundary about 10 to 20 miles away from the coast. These storms will
slowly drift to the west coast as we go throughout the rest of
the evening and early overnight hours.

We will not see much of change next Monday and Tuesday. The only
difference is a little drier air which will allow storm chances to
drop slightly. The bigger change will start on Wednesday as our
upper level flow starts to switch more southwesterly in response to
upper level troughing over the area. This will help to bring deep
tropical moisture over the area through the end of the week and into
our Saturday.

&&

.AVIATION...
(18Z TAFS)
Issued at 244 PM EDT Sun May 24 2026

We are looking at another active seabreeze thunderstorm day across
West Central and Southwest Florida. Most of the storm activity
will once again be in the evening and early overnight hours.
Outside of thunderstorms we can expect VFR conditions with winds
primarily be out of the southeast.

&&

.MARINE...
Issued at 244 PM EDT Sun May 24 2026

Not much changing through Tuesday. We will continue to see
south to southeasterly winds around 5 to 15 knots. Showers and
storms will develop inland in the late afternoon and push towards
the coast and into the Gulf from the late evening into the early
overnight hours. Upper level winds will switch to the southwest on
Wednesday bringing in deep tropical moisture over the area. This
will bring overnight showers and storms over the Gulf that will
push towards the coast in the morning hours.

&&

.FIRE WEATHER...
Issued at 244 PM EDT Sun May 24 2026

Summertime moisture with afternoon showers and storms will
continue through next Tuesday.
