.DISCUSSION...
Issued at 1033 PM CDT Mon Oct 13 2025

A strong 500mb low swings inland along the West Coast and into
the Rockies by late this week, nudging the ridge across Texas out
into the northern Gulf. Weak low pressure and a passing shortwave
bring a brief medium (30-40 percent) chance of showers and
thunderstorms tonight into Tuesday afternoon under the ridge. POPs
then drop to below 10 percent Wednesday through Saturday. A
surface low develops across the Southern Plains over the weekend
and drops into East Texas by Sunday, dragging a cold front south
toward Deep South Texas, with a low (less than 25 percent) chance
of showers or thunderstorms.

Expect seasonal temperatures gradually warming through mid-week,
warming a couple of degrees above normal Friday, and then adding a
couple more degrees on Saturday and Sunday, bringing a moderate
(level 2 of 4) Heat Risk back to Deep South Texas and near triple
digit heat across the brush country and upper valley.

Life-threatening rip currents will continue along the lower Texas
coast Tuesday and return again this weekend into early next week.
Astronomical tides continue to diminish into mid-week with narrow
beaches still likely Tuesday night, but probably falling short of
any Coastal Flood Statement, especially with a lack of surf to
push high tide.
