.DISCUSSION...
Issued at 127 PM CST Thu Nov 20 2025

A slow moving cold front remains on track to push through Texas this
afternoon and evening before stalling just north of South Texas late
Thursday night into Friday morning. Positive vorticity advection
from the front will interact with PWAT values of 1.6-1.75" which
will promote the development of showers, however, the limited
instability and lift in the 700-850mb level will the limiting factor
to heavy rainfall and beneficial rainfall. With the stalled front
and deep moisture pooled over South Texas, rain chances will remain
elevated (35-60%) through the weekend before rain chances taper off
early next week. Rainfall accumulations for the remainder of this
week through the weekend are expected to remain between 0.25-1"
across most of South Texas with the Victoria Crossroads region being
the only area likely to see accumulation over 1" (1-2"). Our next
chance to break this stretch of above normal temperatures will be
mid to late next week with the arrival of our next cold front just
in time for Thanksgiving.

(00Z TAFS)
Issued at 530 PM CST Thu Nov 20 2025

VFR conditions this evening will gradually deteriorate overnight
as increasing low-level moisture and weakening winds support the
development of low stratus and areas of fog across much of South
Texas. CIGs are expected to lower to MVFR/IFR towards daybreak,
with periods of LIFR CIGs and VSBYs possible at some inland
terminals (ALI/VCT) where fog becomes more established. Other
inland sites may experience patchy fog with CIGs below 1000 ft.
Conditions will begin improving by mid-morning as mixing
increases, with widespread return to VFR anticipated by late
morning to early afternoon. Gusty onshore flow early this evening
will ease overnight before resuming at light to moderate levels
Friday, and isolated afternoon convection cannot be ruled out
across the Crossroads by Friday afternoon.

.MARINE...
Issued at 127 PM CST Thu Nov 20 2025

Moderate to occasionally fresh (BF 4-5) southeasterly winds will
continue through before becoming more moderate (BF 4) Friday through
Sunday, keeping seas generally in the 3-5 ft range. Isolated to
scattered showers and thunderstorms will remain possible through the
weekend as an upper-level disturbance approaches. Onshore flow is
expected to strengthen to fresh to strong (BF5-6) early next week
ahead of the next frontal passage.

&&

.FIRE WEATHER...
Issued at 127 PM CST Thu Nov 20 2025

Fire weather concerns will remain low through early next week, as
minimum relative humidity values stay above 40% across the region.
Winds have increased to 10-15 mph ahead of an approaching frontal
boundary, though the boundary itself is not expected to make
significant southward progress into South Texas. With abundant low-
level moisture in place and the front lingering nearby, low to
moderate rain chances (30-60%) will persist through the weeekend.
Another front is forecast to move through early next week. In its
wake, minimum relative humidity is expected to fall to around 30-35%
across the Brush Country. However, lighter winds between 5-10 mph
should keep fire weather concerns minimal.
