Quick update to remove POPs across northwest counties this
evening. Convection continues from the southern Texas Panhandle,
southwest across the Permian Basin region. Latest short range
model guidance keeps this activity west of the area for the
remainder of the evening and overnight hours, so POPs were
removed across the northwest counties this update. Otherwise,
made only some minor adjustments to cloud cover and temps for
the remainder of the overnight period.

(Tonight and Wednesday)
Scattered thunderstorms were developing across the South Plains and
southeast New Mexico, due to weak upper level disturbances moving
northeast through the southwest flow and strong instability. The
storms may make it east into the northwest Big Country and Sterling
County(per the HRRR) after 00Z, and going with slight chance to
chance Pops for this evening. The main hazards from storms will be
wind gusts to 50 mph and dangerous lightning. Otherwise, a warm and
humid night with lows 70 to 75.
For Wednesday, An upper level high over the Lower Mississippi Valley
will be the main influence on our weather, with mainly warm and dry
conditions. Also, low level southerly flow will continue with wind
speeds of 15 to 20 mph with gusts to 25 mph. A few thunderstorms
are possible during the afternoon across far western portions.
Highs will be 90 to 95.
(Wednesday night through next Tuesday)
The subtropical ridge across the southeastern CONUS has begun to
push westward into the area today, and will continue to push west
over the next couple days. This will basically shut down
precipitation chances for our area through the end of the week.
Weak disturbances may move through in the flow to our east and
west on Friday, so have kept slight chances in there for that day.
Otherwise, the forecast should remain generally dry until early
next week when an upper level low will move west out of the Gulf
of Mexico towards our southern counties. Slight chance to chance
PoPs have been retained for the area as this feature moves toward
