.DISCUSSION...
Issued at 1129 PM CST Wed Nov 19 2025

A slow-moving Pacific front currently positioned over the Desert
Southwest will continue its gradual eastward progression across West
Texas through Thursday. As this boundary approaches, the associated
mid- and upper-level trough will evolve into a negatively tilted
system, enhancing southwesterly flow aloft across Texas. This
pattern is already drawing deep subtropical Pacific moisture over
the region, with PWATs across the region progged to climb into the
1.5-1.8 inch range today. While this moisture increase will support
the development of scattered showers, instability and ascent within
the 700-850mb layer will remain limited, which will decrease the
potential for heavier or more widespread rainfall across our area.

By late Friday, the Pacific front is expected to stall just north of
South Texas as it weakens. The combination of persistent moisture
and some modest PVA near the boundary will maintain low to medium
rain chances (20-50%) through the weekend. Most of the CWA will only
see rainfall totals of 0.25 inches or less, while the Victoria
Crossroads stands the best chance of receiving up to 1.00-1.25
inches given its closer proximity to the weakening boundary and
deeper plume of moisture stretching into southeast Texas. The risk
for stronger storms and heavier rainfall will remain displaced to
the north and west of the region. Widespread impacts are not
anticipated locally.

Another upper-level trough is forecast to move eastward from
southern California/northwestern Mexico Sunday into Monday, briefly
reinforcing moisture and lift across the region. This system is
expected to bring another round of scattered showers, with the
greatest rainfall potential displaced north of the region. Rain
chances finally begin to diminish by Tuesday as drier air filters
into the region and large-scale forcing shifts east.

Temperatures will remain above normal through early next week with
highs generally in the 80s and lows in the upper 60s to low 70s,
supported by persistent southerly flow and warm mid-level
temperatures. A more notable change in temperatures is possible by
the middle to latter part of next week as the aforementioned system
approaches, bringing the first opportunity in several days to return
to near-seasonal conditions heading into the Thanksgiving holiday.

.AVIATION...
(06Z TAFS)
Issued at 1129 PM CST Wed Nov 19 2025

VFR and MVFR conditions will continue to trend down to MVFR/IFR
conditions tonight as low-level moisture continues its return to
South Texas. Expect MVFR/IFR ceilings late tonight into early
Thursday morning with IFR/LIFR ceilings possible at ALI and VCT near
daybreak. Some patchy light fog is also possible for ALI and VCT so
have included TEMPOs with MVFR visibility. Conditions will improve
as southeasterly winds strengthen late morning/midday with gusts 20-
25 knots. Showers and thunderstorms are possible by early Thursday
afternoon, but timing is still a bit questionable. While uncertainty
remains, have gone ahead and included PROB30 groups for all
terminals except LRD.

.MARINE...
Issued at 1129 PM CST Wed Nov 19 2025

Moderate to occasionally fresh (BF 4-5) southeasterly winds will
continue through the end of the week, 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 1129 PM CST Wed Nov 19 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 (20-50%) 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 near 5 mph should
keep fire weather concerns minimal.
