.DISCUSSION...
Issued at 1030 PM CDT Tue Oct 14 2025

A strong 500mb low along the West Coast swings into the Northern
Plains by late this week, nudging the ridge across Texas out into
the northern Gulf. This leaves weaker mid-level pressure across
Deep South Texas with limited moisture. POPs drop 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 southward, likely stalling north of
Deep South Texas. POPs have trended further down, now just briefly
above 15 percent. The subtropical ridge returns into early next
week, maintaining dry and warm weather.

Expect seasonal temperatures gradually warming to a couple of
degrees above normal Friday, and then adding a couple more degrees
on Saturday, 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. The heat persists Sunday into Tuesday,
with potential record high temperatures across the RGV.

Life-threatening rip currents are expected to increase this
weekend into early next week.
