.SHORT TERM...
(This afternoon through Thursday night)
Issued at 232 PM CDT Wed Aug 18 2021

West to southwest flow aloft continues overhead today with very weak
ridging moving in behind an exiting shortwave trough. This will
likely result in slightly low coverage of showers and thunderstorms
today with perhaps the highest chances across areas south of
Interstate 10. Otherwise, high temperatures appear to be on track to
peak in the high 80s to low 90s most areas. Low level moisture looks
to persist across the region overnight so low temperatures will
remain a few degrees above normal, in the upper 60s to low 70s.
Thursday, expect thunderstorm activity to increase in the afternoon
and evening hours, particularly across areas south of Interstate 20.
This is due to a weak shortwave trough slowly traversing the region
in southwest flow aloft. Chances for greatest coverage looks to be
near the Davis Mountain and Big Bend region. Runoff due to this
activity could result in rises in water over low water crossings and
creeks. Otherwise, the threat for severe weather is fairly low at
this time. High temperatures Thursday may be slightly warmer than
today with highs generally in the low 90s.

.LONG TERM...
(Friday through  Tuesday)
Issued at 232 PM CDT Wed Aug 18 2021

Upper lvl trough is going move into the high plains by Friday
morning. Scattered thunderstorms will increase Friday afternoon.
Models have been depicting an axis of precip across the Eastern
Trans-Pecos into the the eastern Permian Basin. Convective
temperature, residual boundaries, and upslope will help enhance
precip chances across much of the area Fri. Rain chances will
decrease as the evening approaches but there still is a chance for
an isolated shower or two. Thunderstorms could cause localized
flooding as above normal PWATs will persist. As the weekend
approaches upper lvl ridging will settle over the area. Therefore, a
gradual increase in temperatures is expected to occur. An upper lvl
trough will dive into the high plains Sun however upper lvl ridging
should mitigate most effects. Temps will reach the mid 90s in the
Permian Basin and upper 90s to low 100s in the river valleys by
Tuesday. Precip chances are going to decrease dramatically in the
extended as a result of upper lvl ridging.
