.DISCUSSION...
Issued at 1029 PM CST Sat Nov 15 2025

Mid level ridging over Deep South Texas will move eastward mid to 
late week. This will result in rain-free conditions and above normal 
temperatures across region through at least Wednesday. The 
unseasonably temperatures may lead to record or near record high 
temperatures across the area Sunday through Thursday. Highs will be 
in the low to mid 90s, except for the 80s near the coast, each day 
under partly cloudy skies. Lows tonight are expected to fall in the 
60s, except for the 70s along the beaches, will gradually increase 
into the upper 60s and into the 70s by early next week as low level 
moisture increases. Gusty southeast winds are expected each 
afternoon with a slight increase in winds Tuesday through Thursday 
as the pressure gradient strengthens. A 500mb trough approaching 
from the west on Thursday will bring a low to medium (20-50%) chance 
of rain/thunderstorms Thursday into Thursday night as a weak cold 
front may push into the region early Friday. Some slightly drier and 
cooler air may arrive by late week.
