.UPDATE...
-- Changed Discussion --
Issued at 832 PM EDT Sat Jul 12 2025

Other than some light echoes remaining on radar in interior areas,
the majority of west central and southwest Florida is mainly
rain-free at this time and any of the lingering precipitation
will taper off over the next hour or so. Overall the ongoing
forecast covers these radar trends well so no forecast changes
are needed at this time and a warm and humid night is ahead with
some coastal areas possibly not dropping below 80, though most
areas will be in the upper 70s near the coast and mid 70s inland.

.DISCUSSION...
Issued at 143 PM EDT Sat Jul 12 2025

Weak high pressure in place across the region with weak flow
throughout much of the atmosphere. The main area of showers/storms
earlier this morning into early this afternoon has been across
Manatee and Sarasota counties and moved further inland. Expect
these showers and storms will continue to drift inland with best
chances for showers/storms throughout the remainder of the day
across the interior. PW values vary from > 2 inches from generally
I-4 southward with lower values to the north. Due to this,
continue with best chances for precipitation this afternoon and
evening to the south of I-4. Any ongoing convection should come to
an end near sunset.

PW values over 2 inches become more common going into Sunday and by
Monday PW values will be closer to 2.25 inches. These PW values are
above the 95th percentile for mid July. Due to this PoPs continue
to be on the high side on Sunday and into Monday with best PoPs
across the interior. Highest PoPs on Sunday will be around 70%
increasing to near 90% on Monday. The ridge will breakdown during
this timeframe with an upper low approaching from the east. With
elevated PW values and weak synoptic lift, WPC has placed the area
in a slight risk (2 out of 4) for excessive rainfall on Monday.
Localized flooding could become an issue on Monday, especially in
low-lying areas and areas of poor drainage. This upper level low
drifts to the west throughout the week and models depict a
potential weak surface low. PW values will also remain elevated
throughout much of the week. Due to these factors, PoPs will
remain elevated throughout much of the upcoming work week. With
the higher PoPs, temperatures will be a bit cooler with highs in
the mid 80s to low 90s. The threat for localized flooding may also
persist throughout much of the upcoming week.

The pattern looks to shift back to more of a typical summer time
pattern late in the week with more typical seabreeze showers and
thunderstorms.
