.DISCUSSION...
A surface trough have moved to the east today positioning itself in
the western South Plains. We will likely continue to see isolated
development along this feature through the rest of the afternoon
hours. The atmosphere will remain very weakly capped to no cap under
mixed layer instability on the order of 1000-1500 J/kg. A short wave
was evident on water vapor moving out of central New Mexico along
with a jet max centered over southeast New Mexico. The positioning
of these features will place most upper level lift centered over the
southern Texas Panhandle into the northern South Plains. High cloud
bases with convection will again lead to mostly a strong wind threat
with any storms that do develop.

Upper level ridging will quickly build in tonight. behind the
departing short wave. A strong upper level trough moving across the
northern Rockies will send a cold front into the southern Texas
Panhandle tomorrow. Some isolated precipitation may still be
possible along the front tomorrow evening, especially areas to the
east in Oklahoma. However, the rising heights from the building
ridge will attempt to suppress any development.

The upper ridge will stay entrenched over the region for much of
this week keeping generally warm and dry conditions for the local
area. Moisture and resulting thunderstorm activity will move around
the ridge and therefore around the South Plains. Upper level
troughing will return to the western CONUS this weekend. This may
allow convection to sneak into west Texas but prospects are not high
at the moment.
