.DISCUSSION...
Issued at 1114 AM CST Fri Nov 7 2025

High temperatures are expected to be warm and above seasonal
tomorrow, until a strong cold front associated with a robust Upper
Midwest trough comes through on Sunday, bringing gusty northerly
winds and dropping temperatures below seasonal averages for a few
days. High temperatures will be coldest on Monday, only getting up
to the upper 60s/lower 70s before high pressure settles in for the
rest of the week and temperatures gradually warm up into the upper
70s/lower 80s for Tuesday and the mid-to-upper 80s the rest of the
week.

Low temperatures may be more of a concern for some areas because
this cold front is going to be strong enough to drop temperatures
into the upper 30s for portions of the Northern Ranchlands Monday
night.  Because winds are expected to become light and variable with
clear skies Monday overnight into Tuesday, some isolated pockets of
lower-lying areas in the Northern Ranchlands could see temperatures
closer to freezing in the early morning hours.  Low temperatures
will then gradually warm to the 50s/60s for the remainder of the
week.

This frontal passage is not expected to bring any significant
precipitation chances to Deep South Texas, but potential hazards
such as fire danger, rip currents, and high surf at area beaches are
expected to increase.  A Fire Weather Watch is in effect late
morning Sunday into Sunday evening. Because dry weather is expected
throughout the week, skies should remain clear to partly cloudy.

.AVIATION...
(18Z TAFS)
Issued at 1114 AM CST Fri Nov 7 2025

VFR conditions expected at all airports with clear skies and
light to moderate southerly winds.

&&

.MARINE...
Issued at 1114 AM CST Fri Nov 7 2025

Marine conditions will be favorable tonight and tomorrow, but are
expected to deteriorate Sunday due to a frontal passage.  Small
Craft Advisory conditions are expected, and possibly even Gale
conditions.  A Gale Watch may need to be issued for Sunday, but
further guidance is needed. Winds are expected to shift to a
northerly direction and wave heights are expected to remain high
Sunday through Monday night/Tuesday morning before winds veer to a
southerly direction and conditions momentarily become more
favorable again throughout Tuesday. Wind speeds pick up again on
Wednesday due to a tightened pressure gradient. Small Craft
Advisory/SCEC conditions remain possible Wednesday through Friday
due to increased wind speeds over the Gulf waters.
