.SHORT TERM...
(Today through Tuesday)
Issued at 1231 AM CDT Mon Apr 6 2026
Regional radar imagery still shows some lingering showers and
sprinkles over the Rio Grande Plains and Edwards Plateau. This
activity should continue to weaken as high pressure settles in to
our north Monday. Clouds will be slow to break despite the drier air
as northern and easterly flow weakens during the day. Expect highs
in the lower to middle 70s along with mixed sun and clouds by the
afternoon hours. We are in for at least one more cool night Monday
night as light winds and lower dewpoints result in temperatures in
the mid 40s to lower 50s. On Tuesday, a weak disturbance embedded
within the weak WNW flow aloft will swing through the area. This may
generate a few showers over the Edwards Plateau and northern Rio
Grande Plains, but most areas remain dry. Cloud cover will increase
with the passage of this system, but it won`t have much impact on
the ambient weather.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 1231 AM CDT Mon Apr 6 2026
The forecast remains largely dry through Thursday with the exception
being some low end rain chances over the Coastal Plains each
afternoon. The late week pattern looks more promising for rain in
the region as a powerful storm system moves inland over the west on
Friday. Global Ensembles (GFS/ECMWF) are in agreement on a large
trough moving inland over the southwestern CONUS this weekend, which
would allow a surface trough to develop over the western CWA. The
GFS and ECMWF are both advertising a more active weekend pattern,
but in terms of rainfall amounts and coverage, the ECMWF is more
promising. Ensemble probabilities for >1" of storm total rainfall
ending early next week are between 60-70%, so the potential is there
for some beneficial rainfall this weekend into the early part next
week.

.AVIATION...
(12Z TAFS)
Issued at 516 AM CDT Mon Apr 6 2026
Only some pockets of mid and high level cloudiness are expected
over the next 30 hours, with mainly just high clouds in the later
periods. NE/N winds start off the morning at all sites after the
rising sun mixes out the L/V stuff at daybreak. Then by 18Z, DRT
begins to show signs of return flow with a SE breeze in the
afternoon followed by ESE winds at dusk. Return flow winds will be
slower to come along I-35, and the early day winds could be up to
12 Knots out of the NNE at AUS. Most winds should be below 10
knots by 21Z, and more L/V winds are expected late tonight.
