.KEY MESSAGES...

- Seasonably hot with highs in the 90s and heat index values
  100-107F each day.

- An isolated late day shower can`t be ruled out along the
  seabreeze later today and Wednesday, but most locations will
  remain dry.

- Slightly better rain chances expected Thursday into early next
  week for southern parts of the region as some deeper moisture
  flows back inland.

.DISCUSSION...
Issued at 1251 PM CDT Tue Aug 4 2026

No significant changes were made to the ongoing forecast. With
the exception of an isolated seabreeze/baybreeze shower or
thunderstorm, subsidence and modest moisture levels should keep
rain chances fairly low for the vast majority of the region. As
the days progress Thursday into early next week, we should see
heights fall just a touch across our coastal areas as the western
ridge repositions just a bit further north. This, along with a
developing fetch of SE llvl winds and higher PW`s should allow for
some better rain chances (mainly just scattered diurnally driven
coverage) for our southern 2-3 tiers of counties. High temperatures
should trend down a few degrees as well with the SE flow and more
cloud cover. 47

.AVIATION...
(18Z TAF Issuance)
Issued at 1251 PM CDT Tue Aug 4 2026

Mainly clear skies prevail keeping conditions VFR for the afternoon
and evening hours. A PROB30 for SH remains over IAH, HOU, and SGR
between 21z today and 01z tomorrow, there is still a less than
10% chance of TS. Winds will begin to relax to LGT and VRB around
5-7z across the terminals. This signals for the potential of
another round of patchy mist/fog west of I-45 bringing MVFR
VIS/CIG. CIG/VIS return to VFR after 1500z aided by the increasing
SSE winds. Wednesday afternoon conditions remain similar to today
bringing the possible for afternoon SH/TS. CW

.MARINE...
Issued at 1251 PM CDT Tue Aug 4 2026

Typical summertime pattern will prevail with onshore winds peaking
in the 10-15kt range and seas generally 2-4ft. Rain chances will
slightly increase Thursday into early next week...mainly isolated
to scattered activity in the late night through early afternoon
hours for the coastal waters. 47
