Area Forecast Discussion
National Weather Service Austin/San Antonio TX
710 AM CDT Sat Sep 22 2018

.UPDATE...
Have cancelled the Flash Flood Watch for the remaining counties as
the moderate to locally heavy rains have moved off to the east and
redevelopment is not expected.

&&

.PREV DISCUSSION... /ISSUED 630 AM CDT Sat Sep 22 2018/

UPDATE...
12Z Aviation forecast below.

AVIATION...
RA will continue through around 13Z-14Z at SAT/AUS then move east. An
embedded TSRA is possible until precip clears east. After 14Z MVFR
ceilings will prevail with a NW wind around 10 kts.

PREV DISCUSSION... /ISSUED 400 AM CDT Sat Sep 22 2018/

SHORT TERM (Today through Sunday)...
Cold front encountering a tropically moist airmass with PWs of 2 to
2.5 inches has generated an eastward moving band of showers and
thunderstorms with embedded heavy rains. The band is moving out of
the Hill Country into the I-35 corridor. Have cancelled the Flash
Flood Watch for most of the Hill Country and all of the Edwards
Plateau where rains have ended. Have maintained the far southeastern
Hill Country and added Bexar and Comal counties where the heaviest
rains are ongoing. The band will move east of the I-35 corridor by
sunrise to near the Coastal Plains by midday. Have shifted the POPs
and heavy rain accordingly. Expect the heaviest rains to shift east
of our area during the afternoon. A mid level low will move into
South Central Texas tonight and may cause the front to drift back
northwest a little. A moist airmass lingers east of these features
and have low POPs mainly east of I-35 tonight into Sunday and added
the Hill Country on Sunday in proximity to the mid level low.

LONG TERM (Sunday Night through Friday)...
The mid level low lingers early next week while the front dissipates.
The deepest moisture remains across eastern areas keeping low POPs
there. The mid level low fills and dissipates underneath a broad
upper level trough mid to late week. Deeper moisture spreads to most
areas with low POPs returning to most areas. There is a potential of
a front drifting into Central Texas which could enhance rainfall.
