.AVIATION...

Return flow will persist next 24 hours, enhanced by a modest LLJ
overnight. Convective evolution over the next few hours remains in
question, as hi-res models don't have a real good handle on the
situation. Likeliest terminals impacted by convection overnight
look to be KMAF/KHOB if an MCS materializes north. Otherwise, MVFR
cigs are expected to redevelop KMAF/KHOB overnight, scattering out
to a widespread cu field Tuesday afternoon all terminals, w/bases
4.5-8 kft AGL.

.PREV DISCUSSION... /issued 203 PM CDT Mon May 24 2021/

DISCUSSION...
Upper-level water vapor shows a shrtwv trof that has moved e of nrn
Baja and was crossing Chihuahua, MX where cloud vectors imply
upper- level divergence. Meanwhile the visible imagery shows an
MCV e of the Davis Mtns which looks to be drifting nwd. The MCV's
influence may be such that the upslope flow is increased across
the Upper Trans Pecos-SE NM and may be in close enough proximity
to the dryline to enhance convection, especially if lift from
aforementioned shrtwv trof arrives during or close to the diurnal
heating maxima. The high end sct PoPs we currently have fcst thru
00Z/Tue look to be on the high side and have lowered PoPs some in
the ern CWFA and in the GDP Mtns. The most favored area today is
from INVOF Davis Mtns into SE NM. This evening storms coming out
of SE-EC NM may eventually expand favoring the nrn PB. Storms
this afternoon/evening will be strong- severe with wind and hail
the primary concerns. Tue-Thu the dryline will remain in a wwd
position generally from SE NM-Upper Trans Pecos- bisecting Davis
Mtns at times. Flow aloft will remain sw, but somewhat weak at
times, despite this there will the threat for at least local
strong-severe storms with SB CAPEs above 1500 J/KG each day,
sometimes well above. NAM12 does develop isold-sct storms each
afternoon near along the 50-55 degree isodrosotherms, i.e., SE
NM-Trans Pecos. SW flow is likely to then move storms into at
least the wrn PB. As usual SB CINH will be an issue for storms
(outside of those developing in/near mtns), for example by Wed
NAMBUFR does show formidable cap, ergo 20-30 PoPs. Fri a shrtwv
trof will move across nrn NM/srn Co with an assocd surface front
possibly being the focus for tstms Fri PM across the nrn PB,
otherwise isold across the Lower Trans Pecos. Some indications of
mid-level ridging Sat-Sun with convective potential anchored to
the elevated heat sources. A slow moving mid-level trof is likely
to influence the convective potential in a positive way Mon-Tue.
Cluster analysis is supportive of this trend as well, mid-level
ridging could move e earlier on Sun providing an earlier opening
for convection, at least across the west. High temps will hold
mostly in the U80s- M90s, except hotter along the Rio Grande.
