.DISCUSSION...
Issued at 1151 AM CDT Fri Jul 24 2026

After a prolonged period of active weather, Southeast Texas is
slated to finally have a fair stretch of calmer weather as a 592-600
dam ridge settles in over the Four Corners/Southern Plains region.
Isolated showers (maybe a storm or two at most), will still be
possible this afternoon, decreasing and becoming more sparse in
nature on Saturday and onwards. Nature`s blowtorch kicks into full
force from Sunday throughout the upcoming work week as 850mb
temperatures climb to around 19-25C. This should result in high
temperatures in the 90s to triple digits, with the warmest
conditions currently anticipated around Thursday. Daily heat index
values could reach 104-112 during the afternoon hours (higher in
locally warm spots like asphalt/synthetic turf/etc). Overnight lows
will not offer much relief with early morning temperatures in the
mid 70s/lower 80s. Heat stress on the human body (based on WBGT)
will peak at Extreme levels each afternoon for many spots. Heat
advisories are likely to be needed for at least some duration during
this period, thus heat safety should be practiced closely.

Isolated showers are possible near terminals through early this
evening; otherwise, a dry pattern is anticipated with light to
moderate south to southeast winds. Patchy fog will be possible at
some inland terminals by sunrise. Low confidence exist for MVFR
cigs at KCLL and KUTS late tonight through early Saturday morning.
However, confidence in occurrence is low. Otherwise, VFR
conditions are expected through most of the TAF cycle.
