...FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 10 PM CDT THIS 
EVENING FOR NORTHEASTERN BURNET AND WESTERN WILLIAMSON COUNTIES...

At 726 PM CDT, Doppler radar indicated thunderstorms producing heavy 
rain across the warned area. Between 2 and 5 inches of rain have 
fallen. 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...
  Cedar Park, Georgetown, Leander, Liberty Hill, Florence, Andice, 
  Mahomet, Briggs, Sun City and Seward Junction.

At 718 PM radar estimated rainfall may have exceeded 5 inches near 
the Burnet and Williamson county line at the North Fork of the San 
Gabriel River. About the same time, a social media report from north 
of Liberty Hill indicated the North Fork of the San Gabriel River to 
be near bankfull. Portions of the North Fork of the San Gabriel 
River will probably go out of banks and areas upstream from 
Georgetown Lake.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood 
deaths occur in vehicles.

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

Area Forecast Discussion
National Weather Service Austin/San Antonio TX
153 PM CDT Fri Jun 5 2026

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

.KEY MESSAGES...

-There is higher confidence that pockets of heavy rainfall will
 lead to isolated flooding through tonight. A Flood Watch has
 been issued for Burnet County, the I-35 corridor from Bexar
 County northward, and the Coastal Plains.

- Rain chances continue Saturday, but any storms tonight will
  impact how activity develops during the day.

- Warmer temperatures return next week, with some low rain chances
  mainly along and east of I-35 early in the week.

&&

.SHORT TERM...
(Tonight through Saturday night)
Issued at 148 PM CDT Fri Jun 5 2026

The remnants of the decayed storm system that moved across the Rio
Grande early this morning is seen on radar over the Hill Country and
Rio Grande Plains with scattered showers and thunderstorms east of
this feature at the time of this writing. High PWATS clocking in at
over 2 inches are forecast today which is over the 90th percentile
climatologically for this time of year. Scattered storms will be
efficient rain-makers with high rain rates which will likely lead to
isolated pockets of flooding. Any training of storms will also
contribute to flooding as some soils are already saturated across
the area. Some of the stronger storms could also produce gusty wind
around 40 mph.

Latest guidance has been consistent in localized amounts of 6-8
inches over some portion of the area which has promoted the issuance
of a Flood Watch through late tonight. This includes Burnet County,
the I-35 corridor from Bexar County north and much of the Coastal
Plains. There is lesser confidence for Bexar County, though recent
flooding this morning across the county would mean any additional
storms that move over the area would quickly produce flooding.

Further west there could be some isolated development late this
afternoon, but we will also have to watch for storm development
again across portions of West Texas and Mexico late this afternoon
which could send another complex of storms across the Rio Grande
tonight, though models widely vary on this solution.

What happens today and tonight will play into how things develop for
tomorrow. An upper low will be just northwest of the area Saturday
afternoon, then lifts northeast out of Texas Saturday night. Most
activity on Saturday should be north of the area where greater lift
is located, but with above normal moisture still in place chances
for isolated showers and thunderstorms remain in the forecast.

&&

.LONG TERM...
(Sunday through next Friday)
Issued at 148 PM CDT Fri Jun 5 2026

The upper low which contributed to our wet short-term forecast lifts
northeast into the Central Plains on Sunday. Low rain chances
continue Sunday afternoon, mainly along and east of I-35 though with
only isolated coverage, most will remain dry. Overcast skies Sunday
morning will begin to clear as far east as the Hill Country Sunday
with temperatures rising a few degrees from previous days. Highs
will range from the upper 80s to mid 90s with heat index values in
the triple digits for a good chunk of South Central Texas.

With the subtropical high over the area next week, drier and warmer
conditions make a return. Any rain chances during this time will
mostly be limited to the seabreeze with no other notable strong
forcing mechanisms. Temperatures warm slightly next week with heat
indices hovering between the mid 90s to low 100s depending on the
location. Sunday and beyond, South Central Texas remains in a period
of minor to moderate heat risk so practicing heat safety measures is
recommended.

&&

.AVIATION...
(18Z TAFS)
Issued at 1218 PM CDT Fri Jun 5 2026

Our active pattern continues, leading to lower confidence in
thunderstorm timing today through Saturday. For now, confidence
has increased in TSRA at AUS, so opted for a TEMPO group this
afternoon into early evening to cover the threat. PWATs are up
around 2", near the top of the climatological maximum for early
June, so rainfall rates will lead to rapid visibility reductions.
Opted for 2SM visby's in TEMPO and PROB30 groups today. MVFR
ceilings and then IFR ceilings are expected to develop quickly
after 05Z tonight at AUS, SAT, and SSF. Meanwhile, at DRT,
confidence is low on whether a complex of showers and storms will
develop and push east again late this evening. Will go with a
PROB30 for -SHRA to cover uncertainty.
