.DISCUSSION...
Issued at 229 AM EDT Thu Jul 10 2025
High pressure surface and aloft will hold over the Florida
peninsula through the weekend. An U/L low will approach the
peninsula from the east early next week...and will sit over the
forecast area during the middle part of the week. This will create
a very wet pattern across west central and southwest Florida.

At the surface, little change as weak high pressure will hold
over the forecast area through Saturday with the ridge axis
generally across the central Florida peninsula. This flow promotes
highest pops over the interior and southwest Florida each
day...which is also the region of best available deep layer
moisture. The west/east coast sea breeze boundaries will push
slowly inland during the day with the boundaries colliding over
the interior during the late afternoon/early evening hours
increasing shower/thunderstorm activity. Southwest Florida will be
on the south side of the ridge axis with light east flow to start
the day. This will hold the west coast sea breeze boundary closer
to the coast with increasing shower/thunderstorm activity during
the late afternoon. Due to the weak overall flow and slow storm
movement, locally heavy rain will be possible. Scattered
showers/thunderstorms will likely linger over portions of the
interior and southwest Florida until at least midnight each
evening due to the weak flow, with storms dissipating overnight
with skies becoming partly cloudy.

On Sunday, increasing deep layer moisture associated with the
approaching U/L low will increase pops across west central and
southwest Florida. Highest pops should remain over the interior
and southwest Florida as boundary layer flow will remain weak.

Early next week, increasing onshore boundary layer flow combined
with the U/L low aloft and deep tropical moisture advecting over
the forecast area will bring a significantly greater chance of
showers/storms Monday and Tuesday to the entire region. Locally
heavy rain will be possible. Boundary layer winds will veer to
the south and southeast mid week. Although some drier air aloft
may advect over the region, the low level flow would support
higher pops across west central and southwest Florida along the
west coast sea breeze boundary during the mid/late afternoon
hours as it will be held closer to the coast.

.AVIATION...
(06Z TAFS)
Issued at 229 AM EDT Thu Jul 10 2025
Scattered to numerous showers/storms with LCL MVFR CIGs and VSBYs
will develop this afternoon, with the best chance for storms
across the interior and southwest Florida...possibly impacting
LAL/FMY/RSW/PGD. Storms will persist into the evening hours
dissipating around or shortly after midnight.

&&

.MARINE...
Issued at 229 AM EDT Thu Jul 10 2025
High pressure will hold over the waters through the forecast
period with winds and seas below cautionary levels. Main hazard
through the weekend will be scattered showers/thunderstorms which
will be capable of producing locally gusty winds and rough seas.
Next week, there will be an increase in the areal coverage of
shower/thunderstorm activity over the waters as an U/L low moves
over the region. This will increase the risk for hazardous
conditions for small craft on the waters.

&&

.FIRE WEATHER...
Issued at 229 AM EDT Thu Jul 10 2025
No fire weather hazards are expected as sufficient moisture will
keep minimum afternoon relative humidity values well above
critical levels.
