  possibility into Thursday, but the vast majority of the area
  will remain dry.

- Slightly higher chances of rain on Friday as a brief surge of
  deeper Gulf moisture moves into the area.

  Heat Advisory criteria at times for some locations.

.DISCUSSION...
Issued at 1234 PM CDT Wed Aug 12 2026

A few isolated coastal showers are trying to pop up on the radar
early this afternoon. We`ll probably see a cell or two try to get
going further inland later today, but overall coverage will be low
and they`ll quickly dissipate early in the evening with the loss
of heating. Somewhat similar scenario on Thursday too, but with
even less moisture to work with, POPs aren`t really worth
mentioning for most areas.

Heading into Friday, the northern periphery of some deeper Gulf
moisture seen on sat pix near the Yucatan (associated with a mid
level inverted trof) should briefly track into the region and
slightly enhance rain chances (20-35%).

As this trof makes it further wwd into Mexico, we`ll see
strengthening ridging building in from the east over the weekend
into early next week. With building heights, subsidence, and lower
PW`s...rain chances will be at a minimum or nil.

In terms of temperatures, we`re looking for highs in the 96-100F
range inland and low 90s at the beaches. Heat index readings will
peak between 105-110 most days (flirting with the 108F advisory
criteria for some locations at times). Currently, I`m not planning
to issue one for Thursday considering gusty southerly winds should
provide somewhat of a "relief"...but future shifts will continue
to re-evaluate things. Regardless of an advsy or not, the usual
heat precautions/messaging remains the same. 47

.AVIATION...
(18Z TAF Issuance)
Issued at 1234 PM CDT Wed Aug 12 2026

Clouds will continue to speckle the sky across the area keeping
conditions VFR through the evening hours. Increasing winds, with
gusts up to 20kts out of the SSE, will persist through the day
before decreasing to around 5-8kts overnight. The chance for a
rouge TS/SH induced by the sea breeze remains low, but can`t be
ruled out. Again, the chance for MVFR CIGs and BR to develop in
the western and northern portions does remain tomorrow morning
between 10-14z. CW

.MARINE...
Issued at 1234 PM CDT Wed Aug 12 2026

A prevailing south to southeast flow will continue for the next
several days. Winds are expected to increase to 15-20kt tonight
and remain somewhat elevated into Friday as the pressure gradient
tightens. This will allow seas to build into the 3 to 5 foot
range. Caution flags will probably need to be hoisted in the
evening forecast update. As higher pressure builds into the region
from the east this weekend, winds and seas should gradually
diminish.  47
