.UPDATE...
Issued at 341 PM CDT Tue May 26 2026

We have expanded the Severe Thunderstorm Watch into Atascosa
County with the severe thunderstorm headed into the county from
the west. More storms may form later this evening.

&&

.SHORT TERM...
(Tonight through Wednesday night)
Issued at 1256 PM CDT Tue May 26 2026

As of 1 PM CDT, the line of storms that extends from the San
Angelo's area to the southwest into the Midland's area is
producing heavy rain with rain rates of 1 to 2 inches per hour.
This trend is forecast to continue as the line pushes eastward
this afternoon and evening. This activity is taking advantage of a
mid to upper level trough axis moving across the Southern
Plains/central Texas. As the day progresses, instability increases
to help storms grow to strong and severe weather levels. All
severe weather hazards are possible including very large hail of
2+ inches. Can't rule out an isolated tornado or two. A Level 2 of
5 (Storm Prediction Center) risk of severe thunderstorms
highlights areas west of Highway 281 and Level 1 of 5 risk for
severe thunderstorms east of Highway 281 through Wednesday
morning. Also, WPC ERO Day 1 highlights all of South Central
Texas at a Level 1 of 4 risk of excessive rainfall through
Wednesday morning. As a matter of fact, we are expecting rainfall
rates to be elevated as the convective line of storms moves across
most of the local area through the period. Due to saturated soils
or very wet grounds per last several days, a quick 1 to 3 inches
could cause some sort of flooding issues across the area,
especially over the Flood Watch area. The big concern with this
line is that if slows down as it pushes through Rio Grande
Plains, Southern Edwards Plateau, and Hill Country, then
probabilities go up for isolated spots to get up to 5 inches of
rainfall. Can't pinpoint the locations and therefore, anyone
under the Flood Watch has equal opportunities. The Flood Watch is
in effect from 4 PM through 8 AM Wednesday and takes all
uncertainties into account. The most likely storm timing is mid/late
afternoon and evening along the Rio Grande Plains, late evening
through early overnight over the Hill Country and parts of the
I-35 corridor, and overnight east of I-35 corridor and Coastal
Plains.

By noon Wednesday, most of the shower and thunderstorm activity
should be concentrated east of I-35 corridor with rain chances
diminishing and coming to an end during the evening.

&&

.LONG TERM...
(Thursday through next Tuesday)
Issued at 1256 PM CDT Tue May 26 2026

Dry weather conditions are in store for Thursday and Friday for the
most part. Can't rule out a few showers or even an isolated
thunderstorms along and east of Highway 77 both afternoons. After a
cooler day on Wednesday due to cloud cover and wet grounds, a
warming trend starts for the latter portion of the week with highs
in the upper 80s and lower 90s over most places with mid 90s along
the Rio Grande Plains.

Rain chances return over parts of South Central Texas especially
areas along the Rio Grande Plains and Hill Country per latest
guidance. The somewhat weather pattern continues into early next
week with highs in the 80s and 90s.

.AVIATION...
(18Z TAFS)
Issued at 1232 PM CDT Tue May 26 2026

VFR to MVFR ceilings are seen across the area this afternoon with a
line of thunderstorms developing just west of South Central Texas
over the southern Edwards Plateau. While some isolated thunderstorms
could develop ahead of this main line denoted mainly by PROB30
groups, the expected timing for a line of storms was used for TEMPO
groups. Some lingering showers and MVFR ceilings may be seen behind
this line of storms as well.
