.KEY MESSAGES...
Issued at 1242 AM CDT Thu Jul 23 2026

- Drier post-frontal air will be displaced by some moist easterly
  surface winds from Tropical Storm Bertha across Deep East
  Texas, prompting issuance of a new Heat Advisory for this area.

- Slightly cooler air and some isolated rain chances today (for
  eastern parishes) will offer a brief return to near-normal
  summertime heat (mid-to-upper 90s) through the end of the week
  into the weekend.

- Hazardous heat returns by early next week with increased
  potential of more temperature maximums in the lower 100s.

.DISCUSSION...
Issued at 1242 AM CDT Thu Jul 23 2026

Ridging will continue as the primary driver of weather conditions
through the next week across the Four State Region with some
brief variations as it meanders and changes in strength aloft. As
Tropical Storm Bertha continues shifting west along the Gulf Coast
it will maintain easterly winds across the Ark-La-Tex, quickly
reintroducing the 70-degree isodrosotherm and setting the stage
for hazardous heat to linger as Gulf moisture re-moistens the
atmospheric column. Some isolated showers and thunderstorms could
still form by this afternoon as a result, but they will be the
main windows of any rain chances in the next seven days as the Day
1-7 WPC QPF values suggest most likely rainfall amounts of less
than 0.25 inches areawide. Long-range guidance also suggests that
ridging will build back eastward from the Southern Great Plains to
reintroduce hazardous heat potential through most of the rest of
the month, keeping temperature maximums above average in the lower
100s.

With dew points expected to remain mostly in the low-to-mid 70s
through this time and heat indices ranging at 105-108 degrees,
hazardous heat will be impactful for all groups of people and not
just heat-sensitive groups today (especially across Deep East
Texas). Precautions and awareness are encouraged to continue now
against the elevated potential for heat illnesses. This includes
(and is not limited to) altering outdoor plans, taking frequent
breaks if you must be outside, checking the backseat of your
vehicle, and knowing the signs and symptoms of heat exhaustion in
addition to heat stroke. /16/

.AVIATION...
(06Z TAFS)
Issued at 1242 AM CDT Thu Jul 23 2026

For the 23/06Z TAFs, mostly clear skies overnight will begin to fill
in by daybreak, lowering to MVFR north and east as well as KLFK and
remaining lower VFR elsewhere across east Texas. Patchy mist will be
possible across our southern airspace. Conditions will improve by
mid-morning, before a chance of scattered showers and thunderstorms
arrives from the southeast. Impacts to terminals will depend on how
far north this rain pushes, possibly arriving at KMLU and KLFK
during the afternoon, but confidence does not merit including in
prevailing wx at this time. Northeast winds of 5 to 10 kts overnight
will become easterly during the daylight hours, increasing to 10 to
15 kts with gusts of up to 25 kts possible.
