.KEY MESSAGES...
Issued at 1111 PM CDT Tue Jul 8 2025

- Scattered to widespread showers and thunderstorms are expected
  each day through the upcoming weekend.

- Isolated strong thunderstorms will result in gusty winds and
  periods of heavy rainfall and could lead to ponding of water
  along roadways, as well as minor flooding over poor drainage
  and low lying areas.

- Daily high temperatures will continue to be at or just below
  seasonal temperatures through the weekend. Regardless, it is
  summer in Southeast TX and technically still hot. Make sure to
  take breaks if spending time or working outside and stay
  hydrated.

.DISCUSSION...
Issued at 1111 PM CDT Tue Jul 8 2025

We will likely continue to see a rather active weather pattern
for the next several days as Southeast TX remains wedged between
two high pressure systems, one situated over SW CONUS and another
one situated over the eastern Gulf, allowing for weaknesses to
pass overhead and a mid-upper level trough to scoot into
northeast TX at times. During the next few days, it will generally
be a "rinse and repeat" scenario with passing showers possible
over the waters and coastal locations during the early to mid
morning hours, followed by stronger and more extensive development
of showers and thunderstorms further inland during the mid
morning to late afternoon hours as diurnal heating and instability
increases. There might be slightly less rain chances on Friday as
drier air moves into the region, but will be short lived as
chances rise again on Saturday.

Over the past couple of days, our heavy showers have been
efficient rain makers with rainfall rate between 2 to 3 inches per
hour at times. Given how PWs will stay mostly between 1.8 to 2.1
inches through the upcoming weekend, expect periods of heavy
rainfall with similar rainfall rates to continue. This could lead
to ponding of water along roadways and minor flooding in low lying
and poor drainage areas. Heavy downpours may occur during the
afternoon commute, thus, make sure to check the radar and traffic
conditions before you depart to your destination. Remember, never
cross flooded roads. In addition, if you plan to spend time or
work outdoors or visit our local beaches, be mindful of lightning
given that it can strike many miles away from the storm. When
thunder roars, head indoors.

In response to the rains and cloud coverage, our high
temperatures for the next several days will remain fairly
seasonable. Expect highs to be mainly in the lower 90s for much of
Southeast TX, along with heat indices in the lower 100s. Slightly
higher heat indices could occur for those who are not in or
around any of the rainfall, and although the heat indices are
expected to stay below the Heat Advisory criteria, it may still
result in elevated heat conditions for some. As for our low
temperatures, expect them to be between the mid to upper 70s
inland and the upper 70s to lower 80s for the coastal locations.

.AVIATION...
(12Z TAF Issuance)
Issued at 545 AM CDT Wed Jul 9 2025

Very sparse MVFR CIGs but otherwise VFR conditions broadly
prevail across the area this morning. Scattered showers/isolated
storms are already developing over the Gulf waters this morning.
Storms should move inland and increase in coverage during the
afternoon, later tapering off into the evening as S/SW winds
become light and variable again. Early Thursday morning could see
a few sparse MVFR CIGs, mainly to the north/northwest near KCLL,
though VFR conditions will dominate throughout the period.

.MARINE...
Issued at 1111 PM CDT Tue Jul 8 2025

Light to occasionally moderate onshore winds and 2 to 4 foot seas
will prevail for much of the forecast period. Periods of showers
and thunderstorms are expected daily, with the strongest activity
occuring generally during the morning to early afternoon hours,
although a strong storm or two cannot be discarded later during
the day. Stronger storms could lead to periods of strong gusty
winds and outflow boundaries as well as elevated seas.

Persistent onshore flow will result in a moderate risk of rip
currents along the Gulf facing beaches, although strong rip
currents could still develop at times.
