.SHORT TERM...
(Today through Thursday Night)
Issued at 1258 AM CDT Wed Oct 15 2025

The upper level ridging continues to dominate the local area during
the short term period. However, it weakens throughout the day on
Wednesday as an upper level low pressure system over central
California moves into central and eastern Nevada and an upper level
inverted trough moves across South Texas. At the surface, increased
moisture arrives from the Gulf and pushes pwat values ranging from
1.2 to 1.4 inches (based on the 18Z GFS solution) mainly along the
Rio Grande Plains. There are several hires models showing light
simulated reflectivity over parts of eastern Mexico, but the Rio
Grande and the rest of the local area stays dry with mostly sunny
skies during the afternoon hours and highs in the mid to upper 80s
into the lower 90s. A light wind flow from the east and northeast is
forecast for Wednesday mainly across the Hill Country, I-35
corridor, and Coastal Plains with minimum relative humidity coming
down to the lower 20 percent range. With fuel dryness level forecast
to be on the dry category, can`t rule out fires to ignite mainly
over parts of the Hill Country, I-35 corridor, and Coastal Plains
both Wednesday and Thursday afternoons.

The dry weather pattern prevails on Wednesday evening through
Thursday evening. Overnight lows are forecast to range from the mid
50s to mid 60s areawide. Thursday`s high temperatures remain above
normal climate values ranging from the mid 80s to lower 90s.

.LONG TERM...
(Friday through Tuesday)
Issued at 1258 AM CDT Wed Oct 15 2025

By Friday into Friday evening, the upper level flow comes from the
southwest as an upper level short wave moves across the four corners
region into the Southern Plains. A surface southeast flow is
forecast to dominate the local area with increased moisture from the
Gulf spreading across the Coastal Plains and areas along and east of
Highway 77. There is a slight to low end chance (20 to 30 percent)
for showers and Thunderstorms mainly east of Highway 77 on Friday
afternoon.

The upper level short waves then pushes across South Central Texas
on Saturday with a weak frontal passage moving over the Hill Country
and I-35 corridor, but it does not cross the Coastal Plains.
There is a slight chance for a few showers and storms mainly east
of Highway 77 in the afternoon. High temperatures remain above
normal around the mid to upper 80s to lower and mid 90s.

The upper level ridge build backs by Sunday and marks the return of
dry weather to begin a new week.
