.DISCUSSION...
Issued at 224 PM EDT Wed Sep 10 2025
The big difference in our weather today compared to the last few
days is the front that has been sitting to our north has now shifted
south along I-4. The low pressure system about 100 miles off our
coast has also shifted slightly south. This resulted in some
overcast skies this morning that has just started breaking up in the
last few hours. Shower activity today will be mainly along I-4 and
south. We will have much of the same tomorrow with shower chances
focused south of I-4 with drier air along the Nature Coast.
A strong upper level trough will be pushing through the state on
Friday and this will also help to push the front down into South
Florida. This will keep most of the shower activity along Southwest
Florida as drier air starts to filter into West Central Florida.
This will set up for a beautiful weekend with the only significant
rain shower chances confined to Lee county. Sadly the models have
bumped up lows and dew point temperatures a degree or two which
means most of us will stay in the low 70's instead of getting into
the 60's during the morning hours. But overall humidity will
still be below average for this time of year and will get down to
around 50 to 60% in the afternoon.
This tread of drier air and lower rain shower chances will be
sticking around for Monday and Tuesday.

Issued at 224 PM EDT Wed Sep 10 2025
A front draped across the middle of the state will continue to
produce some gustier winds in our off shore waters with speeds
around 10 to 15 knots. The front has also produced scattered
showers mainly south of Tampa Bay. This trend will continue
through Friday. After that a strong upper level trough will push
through causing the front to push south. This will help to keep us
dry for the weekend however winds will still stay around 10 to 15
knots.

.FIRE WEATHER...
Issued at 224 PM EDT Wed Sep 10 2025
A front stalled across I-4 will continue to bring in ample
moisture for the rest of the week. A strong upper level trough
will push the front south for the weekend bringing in lower
humidity and rain shower chances but nothing near any critical
levels.
