.AVIATION...
/06Z TAFS/

Kept the mention of TSRA in at KABI and KSJT where the best
chances of seeing overnight convection are. One or two of these
storms could produce strong, gusty winds, and/or hail. Othewise,
went with a VCSH. Will update if needed, but most of the
convection is expected to remain farther north and west than KSOA,
KJCT, and KBBD. Have kept the trend of lowering CIGs in the
forecast with a shallow cool air mass moving into the area tonight
into tomorrow morning. 20

/00Z TAFS/

SHORT TERM...
(Tonight and Friday)

Upper shortwave will move northeast across the Panhandle tonight,
with isolated showers and perhaps a thunderstorm early this this
evening, becoming more scattered after 9 PM. The best chance of
rain and storms however will be after midnight, especially in the
Big County, Concho Valley and Heartland as stronger lift comes in,
and a weak cold front moves through. SPC has a marginal risk of
severe thunderstorms south of I-20 and north of I-10 tonight. The
main hazard will be large hail. Friday afternoon, there is also
the potential for an isolated severe storm, mainly along and
northwest of a Sterling City to Sweetwater to Haskell line, with
afternoon heating in the vicinity of the dissipating cold front.
It will be cooler with highs in the 60s in the Big Country
tomorrow, with 70s to the south.

LONG TERM...
(Friday night through Thursday)

A wet forecast continues for West Central Texas into the middle
of next week. A shortwave trough will lift northeast across West
Texas and the Texas Panhandle tomorrow night. Showers and
thunderstorms will likely increase across the area tomorrow night,
as lift increases and interacts with a warm front that will lift
north across the Big Country during the overnight hours. A few
strong to severe storms will be possible across much of the area
Friday night, but the best chance will be across far western
portions of the Big Country and Concho Valley. Large hail and
damaging winds will be the main hazards.

An unsettled weather pattern will continue this weekend into the
middle of next week, as we remain in deep southwest flow aloft,
with weak disturbances moving across the area. Could see the
potential for a few strong to severe storms again Sunday and
Sunday night, with perhaps a better severe weather threat next
Wednesday into Thursday as significant troughing over the
southwest states begins to eject northeast across the Southern
Plains.
