.DISCUSSION...
Issued at 951 PM CST Mon Nov 3 2025

A full cool and dry air advection regime remains in place across
Deep South Texas in the wake of a cool fropa that triggered a few
long-tracked supercells and additional strong to severe thunderstorms
a couple of nights ago. Quiescent weather conditions are expected to
continue through next Tuesday as a 1015-1025 mb sfc high pressure
system remains in place over the region.

Another day of seasonable temperatures are expected to take place on
Tuesday before readings ramp up some as the week progresses, amid a
strengthening 591-594 dam mid-level ridge. By next Sunday or Monday,
another cool front, associated with an amplified and anomalously
strong eastern CONUS trough, is expected to push through Deep South
Texas, which will result in temperatures by early next week
returning back to seasonable levels.

Tonight, the combination of strong radiational cooling amid clear
skies and continued cool air advection will result in overnight low
temperatures falling into the 40s and 50s for much of the region
(lower 60s near the coast). High temperatures on Tuesday are expected
to be in the low to mid 80s across much of the region with pockets
of upper 80s mainly west of IH-69C.

Wednesday through next Sunday, high temperatures are expected to run
between the upper 80s to lower 90s for much of the area with pockets
of mid 90s west of IH-69C. Meanwhile, overnight lows are expected to
run between the 50s and 60s. Monday and Tuesday of next week, a the
passage of a cool front will result in highs in the lower to mid 80s
across Deep South Texas. Overall, temperatures anomalies are
expected to run warmer than normal through the balance of the
forecast period.

winds and low to moderate seas. Sunday evening/night into Tuesday,
