.SHORT TERM...
(Today and tonight)
Issued at 133 AM CDT Tue May 19 2026

...Slight Risk of Severe Thunderstorms this afternoon and
evening...

Cold front just north of Childress at 130 AM expected to move
along I-20 mid morning around 9 AM and then slow down as it moves
south along a San Angelo to Brownwood line 3-4 PM. 

While isolated to scattered thunderstorms expected this morning 
in the Big Country, a larger complex of strong to severe storms 
is expected to develop in the Concho Valley to Brownwood in 
maximum heating this afternoon. Complex then moves south and east 
into the I-10 corridor and NW Hill country this evening. With 
CAPES of 4000 J/kg and 0-6KM bulk shears of 30 to 35 KTS, 
supercells with very large hail over 2 inches possible. The 
complex of storms should move south of West Central by midnight, 
ending most of the severe weather threat. Precipital water values 
around 1.5 inches indicate efficient rainfall producers, and 
localized flooding possible, especially in urban areas. 

.LONG TERM...
(Wednesday night through next Tuesday)
Issued at 1045 PM CDT Mon May 18 2026

By the time Wednesday night rolls around, another low pressure 
trough strengthens across the southwestern U.S. and continues 
moving to the east. This will provide another round of support for
rain and thunderstorm development. High rain chances (80% chance)
will be in place for Wednesday night. The previous rainfall from 
Tuesday could saturate soils to some degree. As a result, 
locations that receive multiple rounds of rain will see increased 
risk of flood related concerns on Wednesday night. The Weather 
Prediction Center has outlooked our area for a Slight Risk (15 to 
40% chance) of Excessive rainfall leading to localized flash 
flooding through Wednesday night. An isolated strong to severe 
thunderstorm cannot be ruled out with large hail and damaging 
winds being the main hazards. 

The long range models continue to show a disturbed weather 
pattern in place as this trough moves east for the later half of 
the work Week. A couple of embedded disturbances within the flow 
are also being indicated as well, which offers support for 
multiple rounds of rain. In the meantime, high rain chances (70%) 
are in place for Thursday. Additional rounds of thunderstorms 
remain a possibility through at least Friday.

We will have to monitor closely for future updates regarding the 
severe weather and excessive rainfall (flash flooding) potential
through the end of this week. Please check back for future 
updates and ensure you have multiple ways to receive any watches 
or warnings that may be issued.

.AVIATION...
(18Z TAFS)
Issued at 1203 PM CDT Tue May 19 2026

Currently VFR at all sites as a cold front moves through from 
north to south. TSRA are expected to develop off of this cold 
front later this afternoon and evening, and affect KSJT, KSOA, 
KBBD, and KJCT during the evening hours. Have kept VCTS and TEMPO 
groups going from late this afternoon into the evening hours at 
these sites to address these storms. These TSRA should dissipate 
by 06Z, after which the cold front is expected to stall somewhere 
in our southern counties, giving east/northeast to northeast winds
for our southern sites, with MVFR CIGs filling in behind the 
front after 06Z, and remaining through most of the morning 
Wednesday.
