.AVIATION.../00z TAFS/
Isolated showers and thunderstorms southeast of the I-35 TAF sites
and in Mexico west of DRT are dissipating and will not affect
those terminals. Tonight`s main aviation concern will once again
be borderline IFR-MVFR ceilings at the I-35 TAF sites. Although
there may be some intermittent MVFR periods after 6-7Z, IFR-MVFR
ceilings should not prevail until after 10-11Z before recovering
to VFR around 15Z. Patchy fog and LIFR ceilings may briefly occur
around sunrise, but for now have only included SCT004 at SSF
between 12-14Z. DRT should remain VFR aside from a brief period
of SCT020 ceilings between 13-15Z with east-southeast wind gusts
of 20-25 knots tomorrow afternoon. Winds tomorrow will be more
south-southeasterly below 15 knots for the I-35 sites.

.PREV DISCUSSION... /ISSUED 340 PM CDT SAT JUL 30 2016/

SHORT TERM (Tonight through Sunday Night)...
The lack of any significant ridging over the area has once again
kept our temps fairly moderate today. We are transitioning however
into a pattern where upper ridging will once again get
established. All ready seeing this influence as radar is fairly
quiet right now with only a few showers starting to show up in the
south and southeast along a developing seabreeze. Kept some 20 pop
in the forecast the remainder of this afternoon to account for
some of this activity moving into the coastal zones and areas
south of San Antonio. Look for low clouds to once again develop
tonight and burn off Sunday morning. With the ridging starting to
take hold on Sunday...pop will be even less and temps will start a
slow climb.

LONG TERM (Monday through Saturday)...
With the ridge established mid week over Texas look for pop to be
zero and the temps slowing warming. Pop will be introduced back
into portions of the forecast late in the week for the south and
southeast zones as deeper moisture moves into Texas from the
Gulf. This deeper moisture associated with a wave over the
Atlantic will be approaching at that time. Its too early to tell
if this system will organize and where it will go...but a westerly
track is anticipated.
