Showers and thunderstorms pose a risk for a couple of tornadoes, occasional damaging gusts, and some scattered flash flooding along the central Gulf Coast. A Pacific storm system continues to bring gusty winds, lower elevation rain, and hazardous mountain snow to the northwestern U.S.. Read More >

.KEY MESSAGES...

region.
- Dry weather with a slow warming trend continues into early next
week.

.UPDATE...
Issued at 410 PM CDT Sat Nov 1 2025
The general PoPs across the region were decent in terms of general
awareness, but the actual locations of where some the higher
precip amounts were to fall have shifted slightly west. The
stronger convective cells are feeding on both synoptic and
isentropic lift in basically a 30 mile swath in the wake of the
cold front as the center of the mid level shortwave tracks SE.
This might shift the higher QPF totals (mainly still below 1/4
inch) into a corridor either side of a line from Burnet to Cuero.
Updated PoP/WX/QPF. The rest of the forecast is unchanged.

.SHORT TERM...
(Today through Sunday)
Issued at 1214 AM CDT Sat Nov 1 2025
A shortwave trough diving southward across the Edwards Plateau into
South Texas and an attendant cold front are contributing to the
development of isolated to scattered showers and storms over the
eastern half of the CWA this afternoon. Activity in the morning
around the Austin area was mostly light and elevated, aided by
strong divergence aloft and an elevated moist layer beneath steep
mid-level lapse rates. However, with some added destabilization
brought upon by daytime heating ahead of the approaching front, a
shift to more surface-based showers and isolated storms is expected
mainly over the Coastal Plains later in the afternoon and early
evening before stable air spreads from the north and shuts off rain
chances tonight. Overall rain totals should remain on the lighter
side, from a trace to about 1/4 inch.
The cooler continental airmass ushered in by Saturday`s weak cold
front will stick around South-Central Texas for about one more day.
A light north wind will make for a crisp and dry night tonight.
Morning lows range from the low 40s in the Hill Country to around 45
to 50 for the remainder of South-Central Texas. That deep-layer dry
air will pave the way for a mostly cloudless and seasonably warm
Sunday afternoon with highs in the 70s. The primary axis of surface
high pressure slides a little more to the east Sunday, so the
coolest spots Sunday night into Monday morning may extend over the
Coastal Plains with lows in the low to mid 40s.

.LONG TERM...
(Monday through next Saturday)
Issued at 1200 PM CDT Sat Nov 1 2025
An upper-level ridge slides east across Texas Monday. Surface high
pressure repositions over the southeastern US but keeps a foot in
our area. With persistent zonal flow aloft, this pattern is
indicative of dry rinse-and-repeat weather for the week ahead. A
weak southerly to southeasterly wind at the low levels reestablishes
by Monday while the jet stream remains well to our north, leading to
a gradual warming trend throughout the week. Widespread highs in the
80s emerge by midweek, and the latest NBM indicates a 50-80 percent
chance of highs above 90 over the Rio Grande Plains and Winter
Garden by Saturday. Expect lows to also rise slowly to the mid 50s
and low 60s by the end of the week. There are some slight ensemble
signals that a marginally more wavy jet stream towards the weekend
could lead to a brief changeup in airmass for our area, but
otherwise expect ample sunshine and warm weather for the next
week.

.AVIATION...
(00Z TAFS)
Issued at 641 PM CDT Sat Nov 1 2025
The cold front has passed through all TAF VCNTYs. Elevated lift
continues over AUS and will impact that area through at least 02Z
with scattered showers. At SAT/SSF, scattered showers and isolated
storms will impact those areas through 02Z with a few residual
elevated showers lasting as long as through 05Z. By 06Z, all
convective concerns should be shifted well south of the TAF sites.
Light north winds resume overnight into Sunday with mostly clear
skies. Southeast winds could return to DRT by late morning, and to
I-35 by early Sunday evening.

.FIRE WEATHER...
Issued at 1200 PM CDT Sat Nov 1 2025
A Rangeland Fire Danger statement remains in effect for Kinney,
Maverick, and Val Verde counties until 6 PM CDT today. North-
northwesterly winds are picking up along the Rio Grande with Del
Rio recently reporting sustained winds of 20 mph as a front pushes
through. Post-frontal winds are expected to spread south along
the Rio Grande, reaching 10 to 20 mph with gusts up to 30 mph.
Coupled with relative humidity values near 20 percent and dry
fuels, this is expected to produce near-critical fire weather
conditions. Good moisture recovery and weaker winds in the evening
are expected.
A Rangeland Fire Danger Statement remains in effect for Kinney,
Maverick, and Val Verde counties until 6 PM CDT today. Elevated to
near-critical fire weather conditions along the Rio Grande are
expected this afternoon as a front passes through the area before
winds subside and moisture recovers after sunset. A gradual
warming trend is anticipated for much of the upcoming week as high
pressure in the mid and upper levels begins to build in from the
west. Southerly flow returns Monday and remains in place for the
rest of the week with speeds generally below 10 mph. Persistent
dry and sunny weather is forecast each day with no rain chances.
Afternoon minimum relative humidity values will tend to reach 25
to 40 percent during the week with the driest spots in the Rio
