AVIATION...
/12Z TAFS/

VFR conditions should continue across West Central Texas terminals
through Sunday morning. Isolated storms remain possible, but
coverage will be extremely limited and the odds if any of the
storms approaching a terminal locations are small. Will not add to
the forecast at this time.

PREV DISCUSSION... /issued 345 AM CDT Sat Aug 19 2017/

SHORT TERM...
(Today and Tonight)

Rain chances continue to gradually diminish across West Central
Texas as an upper level high across Southeast Texas strengthens.
Latest HRRR develops a few isolated showers and storms across the
portions of the Big Country and Northern Concho Valley, roughly in
an area where satellite continues to show some mid level cloudiness
persisting. Will add a mention of isolated storms to the forecast
for this afternoon. Otherwise, fairly quiet forecast with afternoon
highs climbing into the mid and upper 90s today. Overnight lows
tonight dropping into the low to mid 70s.

LONG TERM...
(Sunday through Friday)

An upper level ridge will dominate the weather across West Central
Texas Sunday through Tuesday. Generally hot and dry conditions are
expected. Highs will be in the mid to upper 90s, with overnight lows
in the low to mid 70s.

On Tuesday an upper level trough will swing across the northern
CONUS, while an upper level low approaches South Texas. The passage
of the trough will send a cold front into the Big Country late
Tuesday into Wednesday morning, then stalling across central or
southern portions of the forecast area Wednesday into Thursday. This
boundary will become a focus for shower and thunderstorm
development. PoPs were increased a bit across the forecast area,
generally in the 20-40 percent range. The increased cloud cover and
possible rainfall will also help to keep temperatures down a bit.
Highs will mainly be in the upper 80s to lower 90s, with overnight
lows in the low to mid 70s.
