...New UPDATE, SHORT TERM, LONG TERM...

.KEY MESSAGES...

- A Flood Watch remains in effect for locally heavy rain across the
area along and north of I-10/Hwy 90 through this evening.

- Isolated to scattered thunderstorms are likely into early evening.
Some could be strong to severe from San Antonio to the Coastal
Plains.

- Dry and cooler weather for the weekend with a warming trend for
  next week.

&&

.UPDATE...
Issued at 131 AM CDT Fri May 1 2026

There a couple of severe thunderstorms moving across the area.
These storms are capable of producing hail up to ping pong ball
size. They are moving toward the east and may last for another
hour. We are not seeing any additional development. We expect to
transition to heavy rain storms over the next few hours.

&&

.SHORT TERM...
(Today through Saturday)
Issued at 131 AM CDT Fri May 1 2026

An upper trough is moving across the Gulf of California and the flow
over TX is becoming southwesterly. The front that moved through our
CWA Wednesday has stalled across South Texas and northeastern
Mexico. Winds across the area are from the northeast which has
brought cooler air. Dewpoints showed an initial drop, but have
rebounded and are in the 60s. The deeper atmosphere is very moist
with PW at DRT this evening 1.80" which is above the 90th percentile
of the observation database. The upper trough will move across TX
today providing a lifting mechanism to interact with our very moist
airmass. Scattered showers and thunderstorms are likely to be ongoing
at the start of this period. Some storms will produce locally heavy
rain. We will continue the Flood Watch for the area along and north
of I-10/Hwy 90. For the daytime hours today, the heaviest rain
should be from the Hill Country to the Coastal Plains. Widespread
rainfall totals of 1-3 inches are possible today through this
evening which will be 2-4 inches when added to rain from Thursday
night. There may be a few spots that get up to 6 inches. In addition
to the flood threat, there may be enough CAPE and shear to generate
a few severe thunderstorms from San Antonio to the Coastal Plains.
All severe modes are possible, the risk is Level 1. North-
northeasterly winds will bring a more stable airmass to the region
tonight. Some showers and thunderstorms will linger across the east
until around midnight, but shouldn't produce much more rain. Cooler
air will move in. Lows Saturday morning will range from the mid 40s
over the Southern Edwards Plateau and Hill Country to the mid 50s
along the Rio Grande. Saturday will be dry and mostly sunny. Highs
will remain on the cool side mostly in the 70s.

&&

.LONG TERM...
(Saturday night through Thursday)
Issued at 131 AM CDT Fri May 1 2026

Saturday night an upper ridge will start to build over TX from the
west. Surface high pressure will move across the area. Sunday
morning will be a couple of degrees cooler than Saturday, but then
we will begin to warm back up. Dry weather will continue into the
middle of the week. Highs will be back to well above normal by
Tuesday. Wednesday a dryline will bring low rain chances to the
east. Thursday another frontal boundary will bring more widespread,
but still low, chances for showers and storms. Cooler air will move
in behind this front bringing temperatures back down to near
normal.

&&

.AVIATION...
(06Z TAFS)
Issued at 1242 AM CDT Fri May 1 2026

Showers and thunderstorms are scattered across the region. Storms
are moving through the San Antonio area at this time and should
reach Austin within a couple of hours. There are also showers and
storms in Mexico moving toward DRT. All sites will have off and on
convection through the night and day. Ceilings and visibilities
will vary between IFR and LIFR with occasional TSRA and RA. We
should see some improvement by late evening, but no VFR in this
TAF period.
