...New AVIATION...

.SHORT TERM...
(This afternoon through Saturday night)
Issued at 140 PM CDT Fri May 19 2023

WV imagery shows the upper trough over the Gulf of California,
leaving West Texas and Southeast New Mexico under southwest flow
aloft.  At the surface, a cold front has pushed to south of the
Pecos, but the colder air has hung up diurnally as expected, and
compressional warming ahead of the front should add a few degrees
onto current temps before the afternoon is out. Vis sat imagery
shows a respectable cu field going up along the front, w/forecast
soundings filling in behind it over the next couple of hours.  Also
present on WV imagery is an upper jet moving into West Texas, the
left front quadrant of which will be over Southeast New Mexico this
afternoon.  Mesoanalysis shows deep layer shear 30-40kts along and
north of I-20, as well as Presidio Valley/Big Bend Area.  Mid-level
lapse rates are 7 C/km or better over all but northern Lea County.
Finally, the 88D shows the first convective initiation going up in
the lee of the Davis Mountains.

All this is setting the stage for widespread convection later this
afternoon/evening, with a few supercells and attendant large
hail/damaging winds.  Storm motion is slow enough for some localized
flooding, as well.  Convection should generally develop southwest
overnight with the front, with overnight lows down to right around
normal.  NAM/GFS soundings forecast PWATS overnight at KMAF up to
1.45"/1.32", respectively. Climatological max is 1.36". So, as
severe activity winds down overnight, localized flash flooding
could be of concern.

Saturday, best chances of rain will be over the Davis Mountains/Big
Bend Area invof the front, tapering off in the northeast CWA.
Temperatures will be ridiculously below normal for late May, but
with a big spread among the deterministic solutions.  Considering
expected rainfall and a widespread stratus field, we'll undercut the
NBM just a skosh, for highs Saturday ~ 15-17F below normal.

.LONG TERM...
(Sunday through Thursday)
Issued at 140 PM CDT Fri May 19 2023

The southern High Plains will be under short wave ridging to start
the long term portion of the forecast, then transitioning to
southwest flow as we get later in the week. There will be a chance
of mainly diurnal showers and thunderstorms each day, primarily
across the higher terrain and adjacent plains as well as the
northern Permian Basin. Temperatures Sunday will be a bit below
normal, but with a return to ridging aloft, thicknesses will rise
and temperatures will warm into the upper 70s at higher elevations
in the mountains to near 102 at Rio Grande Village in Big Bend
National Park. Lows in the 50s to near 70 are also expected. All
in all, not a bad forecast, but we could use rain in areas that
haven't seen much in quite some time. -bc

.AVIATION...
(00Z TAFS)
Issued at 634 PM CDT Fri May 19 2023

TS are in the area with this TAF issuance, but the threat to the
terminals is decreasing. HOB/PEQ have the greatest chance for
seeing TS in the next couple of hours, then all TAF sites should
be in better shape with a cold front moving through bringing
stronger northeasterly winds and more stable air. MVFR or high end
IFR CIGs are expected 06-10Z continuing for much of the remainder
of the TAF period. VFR conditions develop at some sites near 20Z.
