.SHORT TERM(Through Thursday)...
North-Central Texas will remain just south of a deformation zone
aloft between the retreating Baja Peninsula upper low and the
longwave trough over the Mississippi/Ohio valleys today. In the
lower levels, the 925-850mb frontal boundary will remained draped
over our Central Texas counties into early this afternoon. The
RAP/HRRR progs seem to have the best handle with the stubborn low
level moisture on the 295K-305K theta surfaces continuing along
and south of I-20.

Clearing will be slower to occur than originally thought, though
areas of north of the I-20 corridor should see only scattered-
broken high clouds by early afternoon, with conditions improving
more by this evening. There is a weak shortwave that is expected
to lift out of West Texas and shear out over our southern counties
today. However, associated ascent appears negligible due to said
shearing into the deformation area overhead. I will hold onto to
the mention of a few sprinkles through midday south of I-20, but
do not expect any impacts or accumulations from the expected weak
activity. Lingering cloud cover, especially across areas south of
I-20 and only neutral thermal advection just above the surface
today will hold afternoon highs in the 70s across much of the CWA,
outside of a few readings warming to around 80 or in the lower 80s
along the Red River Valley and across the far northeast counties.

The north-south drying process will be gradual, but progressive
tonight with clearing skies, as flow aloft veers NW with an upper
ridge steepening to our west. The NW flow aloft will help support
a more progressive entrainment of low level dry air into the area.
Despite high soil moisture values and weakening N-NW winds
overnight, it appears the near surface layer will be too dry for
fog development, outside of some light spotty ground fog possibly
in low-lying rural areas early Wednesday morning. I don`t believe
it will last long or have any impacts to travel to mention in the
late night/Wednesday morning forecast.

Otherwise, mostly sunny, dry, and pleasant early Fall conditions
will be present Wednesday into Thursday with surface high pressure
settling across the area. Lows will cool to between 55 and 60
degrees each morning, so a light jacket may be necessary. A
secondary push of cooler air arrives by early Thursday morning, as
NW flow aloft steepens over the Mississippi Valley. Highs
Wednesday will warm into the 80s, then settle into the 70s on
Thursday.

.LONG TERM(Friday into next week)...
It will remain dry Friday through the weekend, as the low level
surface ridge shifts slowly east of the area. Mornings will start
off cool in the 50s, with highs in the 70s again Friday. The
return of low level southerly flow this coming weekend will allow
for a gradual warm up back into the 80s, with weak ridging in the
mid levels steepens over West Texas. Southerly flow and low level
dew points gradually increase early next week, but still seasonably
pleasant with lows rising back into the lower and mid 60s with highs
in the mid 80s. No precipitation is expected over the next 7 days,
but it does appear a system and cold front may arrive in the mid-
late week time frame that`s beyond the current forecast. This system
will give us our next chance for showers and thunderstorms.

.AVIATION...
/ISSUED 1154 PM CDT MON SEP 26 2016/
/6Z TAFS/

Extensive cloud cover remains in place across North and Central
Texas this evening thanks to some weak ascent above the shallow
cooler air. VFR cigs prevail in the Metroplex tonight and this
should continue through the period. A little farther south...MVFR
cigs still prevail but drier air should slowly filter in
overnight. Will improve cigs at Waco to VFR by 11Z but clouds may
never clear out all together through the day. Outside of the MVFR
cigs tonight...no major aviation concerns are expected. Light
north-northwest winds will prevail through the period.
