Area Forecast Discussion

610 AM CDT Sat May 13 2023

...New AVIATION...

.SHORT TERM...
(Today through Sunday)
Issued at 315 AM CDT Sat May 13 2023

Key points:

-Rounds of moderate to heavy rains expected to continue this weekend
 into next week.

-A Flood Watch remains in effect through early this evening and may
 be extended later into the weekend.

-3 to 6 inches of rain are expected over many areas with isolated
 totals of up to 10 inches possible mainly near the Coastal Plains.

-Be sure to have multiple ways to receive flood and severe weather-
related warnings.

The much anticipated strong to severe thunderstorms and heavy rains
with flooding event is well underway. The line of showers and
thunderstorms has moved east of the I-35/I-37 corridors with showers
and thunderstorms moving up from the Coastal Plains and rain with a
few thunderstorms over the Hill Country to the Rio Grande. The line
will continue to move to the east this morning as the activity from
the Coastal Plains feed into it. The heaviest rains this morning will
be east of I-35 to the Coastal Plains. The activity over our western
areas should gradually decrease. It is possible that the ongoing
heavy rains stabilizes the airmass making for less convective
development in its wake later this morning and possibly this
afternoon. The models show a variety of solutions for today. Still
expect 3 to 6 inches mainly over the eastern areas with isolated
totals near 10 inches. Will continue the Flood Watch through early
this evening. There is a marginal risk of strong to severe storms for
today due to some instability and steep mid level lapse rates.

Deep southerly flow remains over South Central Texas tonight through
Sunday. Quite a few models indicate additional impulses with rounds
of showers and thunderstorms moving up from the south-southwest
tonight into Sunday. There is a good potential for at least locally
heavy rains with WPC showing a slight chance for excessive rainfall
for most of our area. As a result, the Flood Watch may be extended
beyond this evening.

&&

.LONG TERM...
(Sunday night through Friday)
Issued at 315 AM CDT Sat May 13 2023

Deep southerly flow remains over South Central Texas on Monday with
a few models indicating additional impulses with rounds of showers
and thunderstorms moving up from the south-southwest. There is a
good potential for at least locally heavy rains with WPC showing a
slight chance for excessive rainfall for most of our area.

The deep southerly flow early in the week yields to mid level
troughiness for the middle of next week, then upper level ridging
late next week. A moist airmass remains, however, PWs decrease a
little. As a result, chances of showers and thunderstorms along with
heavy rain potential decrease with WPC showing only a marginal risk
of excessive rainfall.

&&

.AVIATION...
(12Z TAFS)
Issued at 610 AM CDT Sat May 13 2023

An area of RA with embedded TSRA will continue over KAUS while SHRA
with OCNL TSRA will continue over KSAT/KSSF this morning. Then,
activity will be intermittent at all sites this afternoon through
Sunday morning, although have maintained SHRA/VCSH mention. A mix of
IFR to VFR conditions is expected with the poorest conditions in
areas of precipitation.
