.SHORT TERM...
(Today through Tuesday)
Issued at 1229 AM CDT Mon Mar 23 2026
A weak frontal boundary is forecast to push across parts of the Rio
Grande, southern Edwards Plateau, and Hill Country before dawn. The
boundary pushes down into the I-35 Corridor extending approximately
from Georgetown to Boerne to Del Rio by around noon time. The front
stays there for most of the afternoon and then pushes back to the
north late afternoon and evening. Low level morning clouds dissipate
between the late morning and early afternoon period with scattered
mid to high clouds moving from central Texas into our local area.
Forecast Monday`s highs range from the low to mid 80s across the
Hill Country to upper 80s along the I-35 Corridor to low 90s over
the southern portion of the Rio Grande. Overnight temperatures stay
between the mid 50s to low 60s areawide.
With the front pushing back to the north and the return of southerly
flow across the entire local area, Tuesday`s highs are likely to get
back into the upper 80s to the mid 90s under mostly sunny to sunny
skies. Clouds develop Tuesday night over the Coastal Plains and I-35
Corridor. Lows are forecast to stay in the upper 50s across the
Hill Country and 60s elsewhere.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 1229 AM CDT Mon Mar 23 2026
Dry and warm conditions continue for Wednesday and Thursday. By
midday Friday, a cold front is forecast to push across the local
area. Temperatures are forecast to be cooler in the wake of the
front, however, they remain above average with mid to upper 80s
across the southern Edwards Plateau and Hill Country and 90s
elsewhere. Medium range and ensemble models are hinting on low to
medium probabilities for rain along the Rio Grande for late Friday
night into Saturday morning. For this forecast package, keeping dry
conditions, however, we could begin introducing PoP for the next
forecast package if models continue this trend. Much cooler for
Saturday in the wake of the front with 60s and 70s areawide. By
Sunday, return flow helps temperatures to rise back into the upper
70s and mid 80s.

.AVIATION...
(12Z TAFS)
Issued at 542 AM CDT Mon Mar 23 2026
Low CIGs ranging from LIFR to low end MVFR along and east of the
I-35 corridor will mix out by midday between 15Z-17Z at the TAF
sites. VFR prevails this afternoon into evening, then IFR CIGs
return overnight into Tuesday morning. A mainly VRBL wind flow as
a front moves into and stalls across the area this morning to
midday, then southerly to southeasterly winds return this
afternoon through tonight.
&&
.FIRE WEATHER...
Issued at 1229 AM CDT Mon Mar 23 2026
Elevated to Near Critical fire weather conditions are forecast
for most days this week across South Central Texas, especially the
Rio Grande. Low relative humidity between the upper teens and low
20s with southerly winds between 10 to 20 mph bring concerns for
any fire that starts to quickly spread. A cold front is forecast
to push across the local area midday Friday and Friday evening.
Best chances for rain out west along the Rio Grande.
