.SHORT TERM...
(Tonight through Monday night)
Issued at 101 PM CDT Sun Apr 12 2026

Broad southwesterly flow at 500mb will continue for the foreseeable
future. This will lead to a series of mid-level shortwaves rippling
through this broad SW flow aloft. Each shortwave may fire off
showers and storms, but both storm intensity and coverage are
highly dependent on the timing of these individual shortwave
disturbances. One such shortwave will move through the region this
afternoon/evening, with the HRRR along with HREF indicating the
potential for flash flooding and severe storms with large hail and
damaging winds.

Locally heavy rainfall that could lead to flash flooding is
possible, especially over the I-35 Corridor and Coastal Plains where
a Flood Watch is in effect through Monday morning for potential of 2-
4 inches of rain with some isolated amounts between 5-10
inches. PWATs between 1.25-1.75" are around 150-175% of of normal
for mid-April over South Central Texas. Any storms that form will
likely contain torrential rainfall, with training of storms
being the primary reason for the flooding concerns.
Rainfall rates of up to 2-3" per hour are possible given the
environment in place and a quick 5-10" is possible within the
watch area. Be sure to monitor the weather and have Wireless
Emergency Alerts active on your phone in the event of a Flash
Flood Warning.

Despite dryline storm initiation yesterday, any convection that
forms this afternoon/evening will be tied to the strength of the
mid-level shortwave embedded in this southwesterly flow. Model Theta-
e forecasts indicate the dryline will sharpen well west of our area,
over West Texas, however, 0-6km Bulk Shear of 35-45 kts, in
combination with HREF SBCAPE values in the 2000-3000 J/kg range will
produce a favorable environment for severe storms to form. Large
hail appears to be the primary concern as well given the HRRR
spitting out MUCAPE values >3000 J/kg and 700-500mb lapse rates
between 7-8 C/km. Any storms that can tap into this environment out
west this afternoon may produce golf ball to tennis ball size hail.
Damaging wind and a tornado cannot be ruled out either, but hail
looks to be the biggest threat. The Storm Prediction Center has most
of our area within a Level 2/5 risk today, given the environment
noted above.

Monday will feature yet another threat for strong to severe storms.
SPC has another level 1 of 5 risk for the Edwards Plateau
and Rio Grande Plains. Monday's storm threat will be focused more on
dryline development than Sunday's storms. Storms would develop over
west of the Rio Grande and move off higher terrain or the dryline
over west Texas and into the EWX CWA. Once again, the greatest
threat from any storms that form looks to be large hail, but
damaging wind is also a possibility. PWATs are not as high on
Monday out west, so the flooding threat is low.

.LONG TERM...
(Tuesday through next Sunday)
Issued at 101 PM CDT Sun Apr 12 2026

The long term period will remain active, as that persistent
southwesterly 500mb flow continues. An upper level trough that's
slowly moving inland over California will finally move into the Four
Corners by Tuesday morning. Another round of showers and storms,
some strong to severe is possible Tuesday, again over the Southern
Edwards Plateau and Rio Grande Plains. Another round of showers and
storms, some possibly strong to severe, will occur Wednesday
afternoon and evening, primarily west of I-35, but some of these
storms could work east into the I-35 Corridor late Wednesday
evening.

The upper level trough will eventually eject and open up over the
Plains on Wednesday, bringing an end to our more active stretch of
weather the past week. Thursday and Friday will feature highs back
in the mid to upper 80s with dry conditions. Beyond that, global
models are actually in agreement on the passage of a fairly strong
cold front for mid-April. While the ECMWF has a passage on Saturday
afternoon, the GFS has a frontal passage on Saturday night. Both
models feature rain and thunderstorms developing along this front.
It is too early to say whether severe weather is possible with this
boundary, but keep checking back over the next couple days as the
forecast is further refined and confidence increases.

.AVIATION...
(18Z TAFS)
Issued at 1241 PM CDT Sun Apr 12 2026

Mostly MVFR conditions are expected today, though further west and
possibly over KSAT/KSSF some periods of VFR may be seen. Showers and
thunderstorms, some of which may be strong to severe, will mainly be
focused from the Hill Country east today with timing tricky for I-35
terminals. Hi-res guidance suggests a later time storms to impact
terminals so pushed back TEMPO groups slightly to account for these
trends. This evening, ceilings drop to IFR and begin to spread west
reaching KDRT before sunrise. Local LIFR ceilings may be seen along
with areas of patchy dense fog, though confidence is not high enough
to include these mentions at any site. Wind remains south to
southeasterly through the period with gusty wind from 20-25 knots in
the eastern half of the area.
