.KEY MESSAGES...
Issued at 1130 PM CDT Sat Aug 9 2025

 - Slightly cooler conditions expected through the remainder of
   the weekend into much of next week.

 - Rain chances return to the area starting Sunday and becoming
   more widespread on Monday and Tuesday.

 - Hot and dry conditions to possibly return late next week.

.DISCUSSION...
Issued at 1115 PM CDT Sat Aug 9 2025

An inverted upper-level trough extending across the northwestern
gulf into the ArkLaTex and the mid-Mississippi River Valley to
bring big changes to the forecast through the remainder of the
weekend into most of next week. Instability associated with the
upper-trough will allow for sufficient mixing to limit high
temperatures to the low to mid 90s through Tuesday. However, with
low-level southerly flow across the ArkLaTex resulting from a
surface high across the Appalachians, dewpoint values in the mid
70s will continue to support afternoon heat index values around
100 to 105 degrees each day.

The upper-trough will linger across Texas into Oklahoma through
the majority of the forecast period allowing for increased chances
for diurnally driven afternoon convection each day across mainly
the eastern half of the ArkLaTex with the highest chances on
Monday.

The upper-trough to eject east on Wednesday night into Thursday to
be replaced by a westward building upper-ridge which will bring a
return of hot and dry conditions across the region late in the
workweek with temperatures by Friday possibly approaching 100
degrees across portions of north Louisiana and south-central
Arkansas. /05/

.AVIATION...
(06Z TAFS)
Issued at 128 AM CDT Sun Aug 10 2025

A mix of thin cirrus and some weak cu across SW AR, NE TX and N
LA prevails currently across our airspace attm. As we go through
the day, look for this cu field to continue growing with the aid
of daytime heating. Cannot rule out some brief ceilings near
4-6kft today along with isolated convection once again across
portions of NE TX, SW AR and N LA. Storm chances do not warrant a
mention in the 06z TAF package however. Any remnant convection
should quickly dissipate after 00z this evening. Look for mostly E
to SE winds today with speeds generally under 10kts outside of
convection outflow boundaries.
