PRECAUTIONARY/PREPAREDNESS ACTIONS...

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

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

In hilly terrain there are hundreds of low water crossings which are 
potentially dangerous in heavy rain. Do not attempt to cross flooded 
roads. Find an alternate route.

Flooding is occurring or is imminent. It is important to know where 
you are relative to streams, rivers, or creeks which can become 
killers in heavy rains. Campers and hikers should avoid streams or 
creeks.

Area Forecast Discussion
National Weather Service Austin/San Antonio TX
153 PM CDT Mon May 29 2023

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

.SHORT TERM...
(Tonight through Tuesday night)
Issued at 152 PM CDT Mon May 29 2023

Synopsis/Mesoanalysis: Evident in GOES water vapor imagery, a weak
area of shortwave troughing is crossing much of the Southern Plains
early this afternoon. Latest RAP analyses place the axis of the mid-
level troughing along a line extending northeast to southwest from
approximately Frederick, OK to Abilene to Del Rio. Convective
initiation is in progress along and immediately ahead of the
advancing height falls, with deepening cumulus and radar echoes
evident from San Saba County southwest into northern Kerr County.
The current concentration of storms over this relatively small
portion of South-Central Texas may be linked to the remains of an
MCV that moved into the vicinity earlier this morning. Additional
shower and thunderstorm development will materialize through the
remainder of the afternoon hours. Activity will be favored over
central portions of the area, where proximity to the slowly-
advancing mid-level height falls will be greatest. Brief downpours
and locally heavy rainfall will be the main concern in these storms,
although an isolated strong to marginally severe thunderstorm with
hail and gusty winds can't be ruled out. Storms will dissipate by
the mid evening hours tonight. While an isolated shower/storm can't
be ruled out along and east of US 77 tomorrow afternoon, the
majority of South-Central Texas should remain dry beyond this
evening.

Rest Of Today: Expect showers and storms to continue to develop over
Hill Country through the next couple hours. Scattered activity
should progress east-southeast into portions of the I-35 Corridor
and Coastal Plains through early evening, when storms should rapidly
weaken as the boundary layer stabilizes. The main concern in any
showers and storms will be locally heavy rainfall, minor flooding
impacts, and cloud to ground lightning. While secondary to the
aforementioned hazards, an isolated strong storm containing large
hail and gusty winds can't be ruled out, especially over the Coastal
Plains where bulk shear values are slightly higher. The Storm
Prediction Center has introduced a marginal (level 1 out of 5) risk
for severe thunderstorms in its latest day one outlook in light of
this small potential. The Weather Prediction Center continues to
carry a slight (level 2 out of 4) risk for excessive rainfall across
the Coastal Plains, with a marginal (level 1 out of 4) risk in place
across the rest of the region. Being Memorial Day afternoon, we
caution those with outdoor plans to remain vigilant to changing
weather conditions. Should a storm approach your area, seek safe
shelter indoors until the storm passes. If you can hear thunder, you
are close enough to a storm to be struck by lightning. Those
planning to hit the roads are reminded to never attempt to drive
through flooded roadways and low water crossings.

Tuesday: Expect high temperatures near or slightly above normal.
Readings should range from the mid to upper 80s across the east to
the lower 90s along the Rio Grande. An isolated shower or
thunderstorm can't be completely ruled out over the far east during
the afternoon hours. Heavy rainfall and severe weather are not
expected at this time.

&&

.LONG TERM...
(Wednesday through Monday)
Issued at 152 PM CDT Mon May 29 2023

The beginning of the long-term forecast on Wednesday will begin dry
as short-wave ridging moves into the area and remains in place
through Thursday. Highs Wednesday and Thursday should top out in the
upper 80s to lower 90s with lows in the upper 60s to near 70
degrees. Winds will remain out of the southeast with speeds
generally 8-15 mph with slightly higher speeds on Thursday expected.
The upper pattern will begin to shift by Thursday night as the sub-
tropical jet begins to work back into the region. This should bring
several disturbances back into the area beginning over the weekend.
This will reintroduce PoPs back into the forecast with the weak lift
in place beginning Friday in the Hill Country before spreading to
the rest of the area on Saturday. As of now, Sunday has the higher
chances of rain in the extended, but there are many model runs to go
ahead of the upcoming weekend. Temperatures throughout the remainder
of the long-term will remain near 90 for highs with lows in the
upper 60s to near 70 degrees.

&&

.AVIATION...
(18Z TAFS)
Issued at 1225 PM CDT Mon May 29 2023

Expect primarily VFR conditions through tonight at our TAF sites. The
San Antonio sites and DRT have occasionally reported BKN cigs at MVFR
levels over the last several hours, but have held off on any TEMPO
groups in the 18Z update given satellite trends and continued rising
bases through the afternoon hours. Anticipate scattered TSRA
development by mid-afternoon along and west of Interstate 35, with CB
possible in the vicinity of AUS, SAT, and SSF through the early
evening hours. Have addressed this potential with a VCTS group given
remaining uncertainties surrounding the precise locations and tracks
of storms. Will continue to monitor trends and adjust this forecast
if necessary. Quiet conditions will prevail from mid evening through
tomorrow. MVFR/IFR cigs may develop closer to daybreak, which has
been accounted for at the San Antonio terminals. Have held prevailing
SCT between FL010 and FL020 at AUS and DRT given lower forecast
confidence.
