.SHORT TERM...
(Today through Saturday)
Issued at 1201 AM CST Fri Dec 5 2025

05/00Z RAOB from DRT shows deep layer southwesterly flow aloft in
place from 700mb above, with plenty of moisture from just above
700mb to 200mb. The 00Z sounding also showed a fair amount of dry
air below 700mb except for a thin layer of moisture near 850mb.
Radar returns are starting to pick up slowly across the Rio Grande
plains, with only a few spots reporting light rain early this
morning. Rain chances today will be favored from the Rio Grande
plains eastward into portions of the I-35 corridor and coastal
plains where moisture levels will be a little higher. Overall
rainfall amounts will remain low, with mainly one-tenth of an inch
or less. A few spots in the coastal plains (east of I-37/south of
I- 10) could see some one-quarter inch amounts. Cloud cover
remains thick, so daytime highs will mostly remain in the 50s,
with near 60 along the Rio Grande. Clouds persist into tonight as
rain chances shift east of the region. Look for overnight lows in
the 40s. Winds trend to a more southwest to westerly direction on
Saturday as clouds decrease from west to east. Highs will quickly
warm into the 70s with perhaps a few upper 60s along the Highway
77 corridor.

.LONG TERM...
(Saturday night through Thursday)
Issued at 1201 AM CST Fri Dec 5 2025

Another cold front will move into south central Texas Sunday
morning, with some cooler temperatures in store for the Hill
Country and nearby I-35 corridor. Farther to the south, the low-
level thermal ridge will be slow to erode and with downslope
northwesterly winds, highs will likely be able to warm into the
mid and upper 70s for areas generally along and south of Highway
90/I-10. Clear skies, dry air and decreasing winds should drop
overnight lows to near freezing across the Hill Country and
southern Edwards Plateau Monday morning. Surface ridging in place
on Monday will yield highs below normal with upper 50s to mid 60s
expected. Southerly winds return Tuesday bringing highs closer to
climatological normals for this time of year. There are some
timing differences noted among the operational models with respect
to the arrival of the next cold front sometime on Wednesday or
early Thursday. The GFS and Canadian are trending faster than the
ECMWF, so we will continue to monitor for temperature forecasts on
Wednesday into Thursday.

.AVIATION...
(06Z TAFS)
Issued at 1201 AM CST Fri Dec 5 2025

MVFR to VFR flight conditions are to begin the period but most
locations, including the TAF sites, improve to VFR conditions by
sunrise with mainly a BKN to OVC deck of mid to high level
clouds. There will be occasional patches of light rain across the
region through early afternoon but this is not expected to have
any flight impacts. Light winds of 8 kt or less prevail with
directions shifting from northerly to southerly for most locations
outside of the Rio Grande. Locations closer to the Rio Grande,
including KDRT, should see the light winds more out of the east
and east-southeast.
