...FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 3 AM CDT TUESDAY FOR
BEXAR, SOUTHEASTERN COMAL, GUADALUPE AND SOUTH CENTRAL HAYS
COUNTIES...

At 1013 PM CDT, Doppler radar indicated thunderstorms producing
heavy rain across the warned area. Between 1 and 3 inches of rain
have fallen. The expected rainfall rate is 2 to 4 inches in 1 hour.
Additional rainfall amounts up to 2 inches are possible in the
warned area. Flash flooding is ongoing or expected to begin shortly.

HAZARD...Life threatening flash flooding. Thunderstorms producing
         flash flooding.

SOURCE...Radar.

IMPACT...Life threatening flash flooding of creeks and streams,
         urban areas, highways, streets and underpasses.

Some locations that will experience flash flooding include...
  San Antonio, New Braunfels, San Marcos, Schertz, Seguin, Cibolo,
  Converse, Universal City, Live Oak, Selma, Randolph AFB, San
  Antonio Int Airport, Stinson Municipal Airport, Canyon Lake, Leon
  Valley, Helotes, Kirby, Alamo Heights, Windcrest and Terrell Hills.

At 1010 PM, radar estimates indicated very heavy rainfall rates of 3
to 5 inches per hour over the city of San Antonio. These intense
rates could be blinding for traffic and could lead to the inability
to see flooded roadways.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don`t drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Move to higher ground now. Act quickly to protect your life.

Be especially cautious at night when it is harder to recognize the
dangers of flooding.

Be aware of your surroundings and do not drive on flooded roads.

Stay away or be swept away. River banks and culverts can become
unstable and unsafe.

Areas affected...southeast TX

Concerning...Severe Thunderstorm Watch 335...

Valid 270357Z - 270530Z

The severe weather threat for Severe Thunderstorm Watch 335 continues.

SUMMARY...Strong to isolated severe gusts should persist overnight with the forward-propagating portion of an extensive QLCS moving east across southeast Texas.

DISCUSSION...The eastern flank of a broad arcing QLCS has been steadily progressing east at 35-40 kts. Despite earlier intense radar wind signatures, measured severe gusts have seemingly peaked around 50 kts with numerous strong, sub-severe gusts along the line. The forward-propagating portion of the QLCS may become detached from the trailing very deep convective cores along its southwest flank over the Brush Country of south TX. Prior convective overturning from earlier in the day activity, well sampled by the 00Z LCH/SHV soundings, suggests the northeast portion of the QLCS should struggle amid weak instability. Modification atop the prior outflow is underway per strong low-level southerlies in the CRP VWP and moderate southwesterlies in the HGX VWP. This suggests the greatest damaging wind potential may lie to the cool side of the pronounced MLCAPE gradient across northern parts of the Houston Metro towards Beaumont.

Getting absolutely slammed with heavy rain, sounds like a war zone outside

[jasons2k]

Discovered a new roof leak. Thankfully it’s under warranty and we got to it before any damage was done.

Strongest winds since Beryl/Ike. I’m sure there will be some trees down in the neighborhood.

[Pas_Bon]

I haven’t seen this much rain since Beryl (League City).
My heart is happy right now. My new landscaping is happier. So grateful..

[Cpv17]

Picked up 2.03” on top of the .35” I had yesterday. Awesome! Happy to see a widespread event!

[Cpv17]

We’ll have to watch tomorrow afternoon into the evening hours for the next possible round.

.AVIATION...
(12Z TAF Issuance)
Issued at 645 AM CDT Tue May 27 2025

Mostly VFR conditions expected today.

Showers will continue to decrease and exit to our east southeast
over the next two hours or so. Iso showers may still be possible
throughout the day, but chances are low. Winds will be VRB for
much of the day, becoming east tonight. Skies are expected to
scatter out during the late morning to afternoon hours, but may
become BKN/OVC later tonight into Wed morning.

[Pas_Bon]

One of my favorite things was walking on the grass this morning and hearing/feeling it squishy and sloshy.

[DoctorMu]

1.85 in last night IMFY. Glad to hear of the broad participation as the MCS blasted through to the coast.

[BAY29]

2.41 here yesterday and another potential good rain tomorrow

.AVIATION...
(18Z TAF Issuance)
Issued at 1224 PM CDT Tue May 27 2025

VFR conditions are expected the rest of this afternoon and parts
of the evening hours with SCT to BKN mid to high clouds. Ceilings
will gradually drop to MVFR and/or IFR conditions late tonight
into Wednesday. This is in response to the next storm system that
will be arriving around the terminals on Wednesday. Confidence in
low ceilings and the exact timing and coverage of any storms is
still low to medium given inconsistencies between model solutions.
At the moment, have PROB30 for all terminals, mainly after 12Z
Wednesday. Showers and storms will likely continue through the
evening hours. Winds will remain light and variable, with
occasional shift to the southeast at around 5 to 10 knots. Low
visibility and higher wind speed/gusts expected with any storms.

It was really bad here in Porter. Everything in my yard got bent out of shape.

[tireman4]

Tonight

[Ptarmigan]

Nice to see some rain.

[jasons2k]

Cleaned up the yard debris in time for the next round. Hopefully not nearly as bad. Glad my roof got fixed!
