.SHORT TERM...
(Tonight through Friday night)
Issued at 152 PM CST Thu Nov 12 2026
Outside of some low clouds trying to develop along the Rio Grande,
skies are clear across south central Texas this afternoon.
Temperatures are still on track to peak in the 70s for most of the
region. Skies should remain clear tonight, with perhaps some late
night/early morning clouds near or just west of the Rio Grande.
Look for overnight lows in the mid 40s to mid 50s along with light
winds. High temperatures on Friday should peak in the 70s again
for most areas as winds gradually return to a more southeasterly
to easterly direction. Some afternoon gusty conditions will be
possible along the Rio Grande. Some mid and high level clouds will
move in from the west during the daytime hours, along with
overnight low cloud development out west across the Rio Grande
plains and southern Edwards Plateau. An approaching upper level
trough combined with a return of the low-level jet will allow for
some showers to develop late Friday night into early Saturday
morning across the Rio Grande plains.

.LONG TERM...
(Saturday through next Thursday)
Issued at 152 PM CST Thu Nov 12 2026
On Saturday, the above mentioned upper level trough axis slowly
moves from west to east across the region. While we continue to
see some differences in the operational GFS (stronger trough) and
ECMWF (weaker), we should see enough moisture and lift to yield a
good chance for rain, especially late Saturday through Sunday
afternoon. With a decent chance for rain and increasing cloud
cover, look for highs in the 60s to near 70 degrees on Saturday.
The high temperature forecast for Sunday will be tricky as most
models indicate a front remaining to our north. However, given the
trends of the ECMWF in showing a stronger frontal push on Sunday,
we have opted to lower highs across portions of the northern Hill
Country into the I-35 corridor. If the cooler ECMWF verifies, we
will need to lower highs much farther south, perhaps as far south
as I-10 in subsequent forecasts. Rain chances taper off Sunday
night as the upper level system slides east of the region. Given
the continued eastward movement of this upper system, rainfall
amounts will be lower along the Rio Grande, with near 1/4"
expected, while farther east into the coastal plains and Highway
77 corridor, up to 1.5" will be possible.
Highs on Monday will be much cooler, with lower 50s to lower 60s
in the current forecast. With plenty of clouds and cold air
advection, suspect we will need to lower highs downward, with
perhaps some upper 40s in the Hill Country. The cool temperatures
will linger into Tuesday with surface high pressure in place and
plenty of cloud cover. Winds will begin to transition to a more
east to southeasterly direction for Wednesday into Thursday as
broad southwest flow aloft sets up over the region. This in
addition to the subtropical jet overhead will return some low
precipitation chances to the forecast for most areas.

(00Z TAFS)
Issued at 521 PM CST Thu Nov 12 2026
High pressure over the area will keep winds light and maintain VFR
conditions through Friday night. Skies should remain clear. At KDRT,
an 8-10 kt southeast prevailing wind should establish by around 16Z
and hold steady through Friday afternoon. Elsewhere, winds will
remain light and largely below 6 kt. Winds at KAUS/KSAT/KSSF
through Friday will likely have variable wind directions with
only subtle hints of a prevailing direction.
