AREA FORECAST DISCUSSION...UPDATED

.AVIATION...
/00Z TAFS/

Scattered showers and thunderstorms over west and northwest Texas
are slowly moving east this evening. A few of these may enter our
western and northwestern counties, through early tonight. Have
more uncertainty on whether any of our TAF sites will be
affected. KABI and KSJT may potentially be affected, and will
monitor radar trends for possible update and inclusion of TSRA.
Otherwise, high cloud cover from the aforementioned convection
will overspread West Central Texas this evening and early tonight.
On Friday, scattered showers and thunderstorms will be possible,
mainly during the afternoon and across the Big Country area north
of Interstate 20. Patchy low cloud development is possible toward
morning across some of our southern counties, and have a scattered
layer included at KSOA and KJCT. Southeast winds will veer to the
south overnight and continue on Friday morning.

SHORT TERM...
(Tonight and Friday)

Rain chances for the next 24 hours continue to look more promising.
The latest WSR-88D data indicate showers and thunderstorms are
developing across the Big Country. The RUC indicates this activity
will continue to develop and spread into mainly our northwestern
counties during the next 6 hours. Overnight tonight, the NAM
fragments the QPF into small areas across mainly our northwestern
counties. Given the uncertainty across our southeastern counties,
slight chance PoPs still look good there. Elsewhere, and especially
north of our Interstate 20 corridor, chance PoPs look best. As the
upper trough axis pushes farther east tomorrow, the better rain
chances will expand south and include more of our southern counties.
The main thunderstorm threats for the next 24 hours are deadly
lightning and flash flooding from locally heavy rainfall.

Huber

LONG TERM...
(Friday night to Thursday)

While the upper trough will be east of the region Friday night and
Saturday, a weakly capped atmosphere will remain. Therefore,
isolated, mainly afternoon and evening showers and thunderstorms
will continue to be possible. The upper ridge strengthens Sunday,
however, with hot and dry conditions expected through next week.
Highs are expected mainly in the mid 90s.
