Area Forecast Discussion
National Weather Service Austin/San Antonio TX
623 PM CDT Sat Aug 5 2017

.AVIATION DISCUSSION...FOR 00Z TAF PERIOD...
Isolated -TSRA currently located west of the KAUS terminal this
afternoon while KSAT/KSSF is mostly clear and VFR. KAUS has a very
low chance for a terminal impact in the first couple hours of the TAF
period but believe these will be too short lived and isolated to
warrant a prevailing or TEMPO line.

Farther west at the KDRT terminal, TSRA is much more likely as
outflow is already passing through the terminal at TAF issuance.
Included TEMPO group there for first few hours of the TAF to account
for reduced VIS due to heavy rainfall. Winds should be out of the
south with the storm outflow winds. -RA expected for several hours
afterwards off and on through about 00-01Z then VFR to prevail
afterwards.

&&

.PREV DISCUSSION... /ISSUED 600 PM CDT Sat Aug 5 2017/

UPDATE...
Have increased pop out west along the Rio Grande into the 30-40
percent range as storm activity in Mexico has pushed outflows into
Maverick County and the border area. Look for additional convection
to fire in this region as a result. With some upper level support,
storms may last past sundown.

PREV DISCUSSION... /ISSUED 252 PM CDT Sat Aug 5 2017/

SHORT TERM (Tonight through Sunday Night)...
Upper air analysis this morning showed the subtropical ridge pushing
up into Texas from the southwest with west-northwesterly flow over
us. At the surface, winds were from the south to southeast. With the
ridge building up convection was being kept to our east. There will
continue to be a slight chance for showers and thunderstorms tonight.
A weakness in the ridge will develop tomorrow and we expect an
increase in rain chances for Sunday and Sunday night. As usual the
best chances will be over the eastern half of the CWA where there
will be better moisture.

LONG TERM (Monday through Saturday)...
Monday a frontal boundary will move through north Texas stalling
somewhere north of our CWA. Low level flow will keep moisture high
with PW near 2.0 inches across most of the area. The front will come
close enough to produce showers and thunderstorms across the northern
half of our forecast area. Since the front will stall and slowly
dissipate north of us, rain chance will continue into Wednesday.
Beyond that point we will revert back to the summertime pattern of
low POPs during the day and evening mainly over the eastern half of
the area.
