...New AVIATION...

.AVIATION...
(00Z TAFS)
Issued at 523 PM CDT Sat Jul 24 2021

VFR conditions will prevail next 24 hours in light return flow.
Scattered convection will diminish w/loss of diurnal heating,
w/best chances at KFST. Forecast soundings develop a widespread cu
field late Sunday morning, w/bases initially 4.5-6 kft AGL, and
more convection possible Sunday afternoon, especially invof KHOB.

&&

.SHORT TERM...
(This afternoon through Sunday night)
Issued at 152 PM CDT Sat Jul 24 2021

As the 80s song goes, the heat is on. We have enjoyed a recent
period of below average temperatures as high pressure normally
centered close to West Texas in the summer, has instead been located
over the western states where they have been plagued by heat. That
is starting to change with the high pressure out west breaking down
and repositioning over the South Plains. Southerly low level winds
will advect warmer temperatures out of northern Mexico causing
temperatures to increase both today and tomorrow. Fortunately, the
upper jet is located far enough south to dampen the high enough so
heights remain near normal, so while temperatures will be hot this
weekend they will not be too far from normal.

Radar is already showing convection developing west of the Pecos
River today and more activity is expected later this afternoon and
evening with peak heating before diminishing overnight. Subsidence
associated with the upper high will increase Sunday and storms
should be more isolated in coverage. Shear is weak so storms will
remain below severe levels.

&&

.LONG TERM...
(Monday through  Friday)
Issued at 152 PM CDT Sat Jul 24 2021

The long term will be mainly dictated by the strength and
positioning of the ridge to the north as it settles over the central
plains. Near to above normal height pattern will allow for temps to
trend slightly above normal for Mon/Tue before we see a slight shift
in the upper pattern. Global models are keying on a transient
tropical piece that rotates out of the Gulf and moves west under the
guide of the ridge. The piece isn't overly strong, but certainly
favors a wetter solution compared to blended guidance, so upped PoPs
over most of the forecast area for Wednesday when the piece is
progged to reach the area. Outside that, it's ridging for days with
isolated to scattered convection in the far western areas, mainly
our high terrain focal points in the Davis and Guadalupes. Temps
will drop for mid-week with our disturbance, but we'll see them come
back to near and above normal by Thu, onward. Lows will settle into
the upper-60s and 70s areawide.
