.DISCUSSION...
Issued at 1146 PM CDT Thu Jul 10 2025

Our region saw much less diurnally driven convection on Thursday
and this was due in part to less PWAT or available moisture and
less upper forcing from a very weak shear axis ovhd. These have
been our driving ingredients to seeing more storm coverage over
the last several days and taking a look at these parameters again,
we should see even less coverage today. Highest PWATS for this
afternoon will again be across our far southern and eastern zones
so this will limit pop coverage to low end chance variety across
these areas.

For Saturday into Sunday, did not deviate from NBM which is
painting slightly higher rain chances, but not by much, due in
part to a weak shortwave moving out of the Southern Plains and
into the Middle Red River Valley and an uptick in available
moisture or PWAT across our northwest most zones and perhaps a
little more in the way of an active seabreeze from the south due
to the proximity of upper ridging located across FL.

Both today and through the upcoming weekend, persistence is the
best rule of thumb when it comes to temperatures. This is in
agreement with NBM temps with daytime highs mostly in the middle
90s today, maybe a degree or two cooler across our far northern
and southern zones this weekend due to increased rain chances.
While some isolated locations across our forecast area will see
daytime heat indices near or exceed 105 degrees, these values are
not widespread enough to warrant necessary Heat Advisory headlines
through at least Sunday but all bets are off for the upcoming
work week.

The above mentioned upper ridge appears to expand and/or
retrograde westward into the Lower Miss Valley/Tenn Valley Monday
through Wednesday of next week. Subsidence in association with
this feature should result in ambient max temperatures approaching
triple digits if not meeting or exceeding triple digits in some
locations. This combined with elevated dewpoints will result in
daytime heat indices meeting or exceeding 105 degrees and
therefore, Heat Advisories will likely become necessary. Will
watch the northeast Gulf of Mexico by the end of the forecast
period for perhaps some relief from the heat in the form of
increased rain chances, at least across our southeast half in the
Thursday/Friday timeframe but most of the remainder of our region
should remain dry Tuesday through the end of the forecast period.

.AVIATION...
(00Z TAFS)
Issued at 738 PM CDT Thu Jul 10 2025

For the 11/00Z TAF period, VFR conditions prevail this evening as
afternoon convection has just about diminished entirely as sunset
approaches. Cu field will also largely dissipate, but lingering
convective debris clouds may linger through this evening closer to
KMLU. Otherwise, look for some patchy low stratus to return around
daybreak near KLFK and possibly as far north as the I-20 corridor.
However, have only included low cigs at KLFK for this TAF cycle.
S/SW winds will generally prevail throughout the period as speeds
drop off overnight and then increase once again between 6-12 kts
on Friday with higher gusts possible across our East TX terminals.
