1057 PM CST Fri Nov 17 2017

.AVIATION...
/06Z TAFS/

VFR conditions are expected to continue across all 5 terminals
for the entire TAF period. KABI is rather gusty right now as the
low level jet has kicked in, but the remainder of the terminals
are generally light. However, the main concerns will be
associated with the passing of a cold front Saturday morning.
Winds will shift and be from the north and become much stronger
over the course of the morning. Gusty conditions are also likely
to develop Saturday morning as well. This will last for much of
Saturday afternoon before winds start to relax for Saturday
evening and Saturday night.

AVIATION...
/00Z TAFS/

VFR conditions are expected to continue across all 5 terminals
for the entire TAF period with fairly breezy southerly winds
persisting. However, the main concerns will be associated with
the passing of a cold front Saturday morning. Winds may slow a bit
overnight for the southern 3 terminals, however, winds will shift
and be from the north and become much stronger over the course of
the morning. Gusty conditions are also likely to develop as well.
This will last for much of Saturday afternoon before winds start
to relax for Saturday evening and Saturday night.

SHORT TERM...
(Tonight through Tomorrow)

Windy and cooler...

Expect a quiet evening across the region. The southwest winds
will diminish after sunset and temperatures will begin to cool
off. A few high clouds will move in from the northwest ahead of
the cold front. Overnight lows will be in the in the mid to upper
50s. A cold front will move through the area during the day on
Saturday. The front will bring cooler temperatures and strong
winds. Temperatures will top out in the upper 60s with areas along
the I-10 corridor seeing temperatures in the lower 70s. Gusty
northerly winds will spread across the area, with the strongest
window for winds occurring during the late morning through the
late afternoon hours. Sustained winds will be between 25-35 mph
with isolated gusts up to 40 mph. Motorists along the I-20 and
I-10 corridors should use caution, especially those driving high
profile vehicles.

LONG TERM...
(Saturday night through next Friday)

Following the cold front and windy conditions Saturday, the parent
surface high pressure area will move south into TX and OK Saturday
night. This will result in winds becoming light by early Sunday
morning. The combination of the colder, drier air mass, clearing
skies, and light winds will result in temperatures dropping into
the 30s across west central Texas, with a few Concho Valley and
southern low lying locations possibly dropping to around
freezing. Cooler temperatures will continue through Sunday with
highs only expected to be in the upper 50s to around 60 degrees.

For next week, mainly a dry forecast for most of west central
Texas. Temperatures will warm back up to around normal for Monday
into Tuesday with highs in the 60s to lower 70s. However, a fast
moving shortwave trough will swing through Texas Tuesday into
Tuesday night. This will push another cold front south into our
area as well as give southeastern counties a slight chance for
some light rain Tuesday night. Cooler temperatures again on
Wednesday following that cold front with a warm trend from
Thanksgiving into Friday.
