.AVIATION...

Return flow will prevail next 24 hours, enhanced by a 40+kt LLJ
overnight. An incoming shortwave overnight will bring another
round of convection to the area, and KCNM/KPEQ look to have the
best chance of seeing anything, at least according to the NAM.
Forecast soundings develop mainly MVFR cigs overnight all
terminals, which should persist thru late morning Sunday, giving
way to a widespread afternoon cu field w/bases ~ 4-4.5 kft AGL.

.PREV DISCUSSION... /issued 239 PM CDT Sat May 29 2021/

DISCUSSION...

The sun is finally out this afternoon after our severe storms
yesterday. Weak upper level ridging will help keep much of West
Texas dry this afternoon, but instability out west stretching from
SE New Mexico down to the Davis mountains and higher shear values
will likely cause a few strong to severe storms to develop later
this afternoon. Hi-res models are mostly in agreement that this
convection will track eastward and die out before reaching the Trans
Pecos or Permian Basin, but a rogue storm making it further east is
not out of the question. The front that moved through the other day
is helping to keep our temperatures this afternoon relatively mild,
with mostly 80s expected across the Permian Basin and 90s along and
S of the Trans Pecos.

A closed low off Baja CA will be moving over AZ on Sunday, sending
disturbances through our area as moisture deepens over West Texas
and SE New Mexico. Severe weather is expected with this set up, and
storms are likely to develop along the dryline in SE New Mexico by
midday on Sunday . Similar to what we saw on Friday, there may be
multiple rounds of storms from the dryline that track eastward
towards the Lower Trans Pecos on Sunday while another MCS pushes
down into SE New Mexico and the Permian Basin from the north. This
is looking to be a long severe event from Sunday afternoon into
Monday morning. Likely these storms will be producing very large
hail, heavy rainfall, very strong wind gusts, and even a few
tornadoes. Localized flash flooding will definitely be possible with
these storms.

Highs Sunday afternoon will be in the 80s area-wide with even cooler
temperatures on Monday thanks to increasing cloud cover. Memorial
Day is looking to be wet with storms likely continuing off and on
throughout the day on Monday. While the severe threat will be less
on Monday compared to Sunday, storms will be capable of heavy and
persistent rainfall that may lead to some localized flash flooding,
especially in urban areas and in and around streams. Beyond Monday,
temperatures will remain well below normal with mostly 70s in the
Permian Basin and 80s along the Trans Pecos for both Tuesday and
Wednesday. By the weekend, temperatures will be back into the mid to
upper 80s. Thunderstorm chances decrease after Tuesday, but will
continue to be possible each day through the weekend.
