.SHORT TERM...
(Tonight through Monday night)
Issued at 1119 PM CDT Sat Aug 9 2025

After seeing PWATs below 1.75 the last day or so, we will see
moisture start to return to the area on Sunday with PWATs already
surging up above 2 inches by the afternoon. This comes as we see
winds turn to onshore flow later in the day Sunday and remain that
way through the forecast period. While Sunday won`t see quite as
high of PoPs as the rest of the period, isolated showers and storms
are likely to fire across the area, especially for areas south of I-
12 where PoPs are in the 50-70% range.

Monday can expect somewhat similar conditions as Sunday, but PWATs
are looking to be even higher as that onshore flow continues to
surge moisture in. PoPs for the entire forecast area are in the 60-
80% range mostly throughout the afternoon hours. WOuld not be
shocked to see a couple storms on the stronger side, possibly up to
severe, with locally gusty winds and heavy downpours.

Temperatures won`t se much of a change through most of the period
with scattered to widespread convection each day. Afternoon highs
peak in the low 90s with heat indices peaking around 105F, below any

.LONG TERM...
(Tuesday night through Saturday night)
Issued at 1119 PM CDT Sat Aug 9 2025

Most of the long term period won`t be too much of a change from
Monday. Tuesday and Wednesday may end up being the wettest days of
the week for a good chunk of the area, with PoPs in the 70-80%
range. Once again a couple of these storms have the chance to be
locally strong to even severe with locally gusty winds and heavy
downpours.

Towards the end of the week we finally start to see the PoPs
forecast start to trend down some, into the 50-60% range which is
pretty typical of a summer day down here. Temperatures will also
tick up, with afternoon highs closer to the mid 90s for most areas.
By the end of the week, if rain chances stay on the lower side, may
end up close to heat headline criteria.

(12Z TAFS)
Issued at 643 AM CDT Sun Aug 10 2025

Terminals were VFR at forecast issuance time, although scattered
SHRA/TSRA were just offshore to the east and south. Main concern
to aviation operations today will be TSRA, with the main question
being how quickly the storms offshore progress northward. At least
isolated TSRA could reach KHUM/KMSY/KNEW during the morning hours,
with more widespread convection by midday as convective
temperatures in the mid and upper 80s are reached. MVFR ceilings
with any convection area pretty much certain, with IFR
visibilities and gusty winds also possible. The "least" likely
terminals for convection will be KMCB and KBTR, but there`s enough
of a threat there to at least justify PROB30. While most
convection should weaken or dissipate around sunset, there could
be a few storms beyond that point, which later forecast will fine
tune the locations on. Could also see coastal redevelopment around
sunrise Monday.

.MARINE...
Issued at 1119 PM CDT Sat Aug 9 2025

Winds and waves will remain mostly calm through the forecast period,
with winds staying below 15kts each day. The only marine concerns
through the forecast period are related to convection. Winds and
waves will be locally higher around any thunderstorms that develop.
The early morning hours have the best chances of marine convection
each day with some storms on the stronger side bringing higher winds
and seas. convective coverage is expected to increase heading into
the work week.
