.SHORT TERM...
(This afternoon through Tuesday night)
Issued at 156 PM CDT Mon Aug 22 2022

NW flow aloft with lessening influence from the departing shrtwv
trof to the e. The primary mid-level theta-e ridge axis has
shifted s as has the front, but RH at 7h and 5h will be some
what slow to decrease across the PB. Satellite indicates rapidly
cooling tops near the Rio Grande where L90s/U60s (T/Td) have made
for strong SB instability with a high probability of heavy rain.
Recently river levels on Rio Grande have fallen below action
stage, but with renewed heavy rain flooding/flash flooding of Rio
Grande tributaries and on Rio Grande are still a possibility.
Elsewhere storms that form this afternoon will slowly decrease
into the evening, but the possibility of a SHRA/TSRA will remain
thru the night across the Trans Pecos where said theta-e ridge
will reside. Despite the cyclonically curved nw flow aloft PoPs
will decrease Tue, especially for areas n of I-20 with a gradual
taper from isold near I-20 to scattered PoPs in the Trans Pecos.
NBM PoPs again seem too high and have trended down. Mid-level
theta-e ridge lingers INVOF Rio Grande and low order PoPs are
justified there into Wed AM, again NBM is too high. As far as
temps go Tue AM will be nice low/mid 60s far NW CWFA, mid/upper
60s most of PB, and 50s mtns. Increased insolation Tue PM will
push temps into mid/upper 80s for most areas.

.LONG TERM...
(Wednesday through  Sunday)
Issued at 156 PM CDT Mon Aug 22 2022

Continued rain chances and below normal temperatures will be the
rule through the extended. Aloft, ridging will remain over the
western CONUS while a longwave trough slowly progresses toward the
East Coast, maintaining weak northerly to northwesterly flow over
Southeast New Mexico and West Texas later this week. At the
surface, easterly upslope flow will continue, maintaining
thunderstorm chances each day across the higher terrain and for
locations south of I-20, particularly those along and south of
I-10. Given a lack of significant upper support, severe weather is
not expected, with heavy rain and associated flooding/flash
flooding remaining the primary concerns with storms that develop.
Given the southern focus for storm development through the end of
the week, flooding concerns may evolve across the Davis Mountains
and Big Bend Area, as well as through the Rio Grande Valley where
elevated flows have been observed due to heavy rains over the Rio
Conchos basin.

Heading into the weekend, southerly surface flow looks to return
to the region, coincident with a shortwave moving through the
Central Plains. The passing shortwave will yield an expansion in
rain chances over the weekend, with this weekend looking like the
next good opportunity for storms over the Permian Basin.
Temperatures will remain below normal with highs in the 80s for
most Wednesday and Thursday, with a warming trend expected through
the weekend with highs in the lower 90s expected to return for
areas north of I-10. Lows will also remain on the mild side, in
the middle 60s and lower 70s midweek onward.

Issued at 621 PM CDT Mon Aug 22 2022

VFR conditions should prevail next 24 hours most terminals.
Forecast soundings suggest MVFR cigs will be possible, mainly
KMAF/KFST, but drier air is moving in behind the front, and this
(and mid/high cloud) may keep cigs from lowering further.
Otherwise, light post-frontal winds will veer slightly through
the forecast period. Convection will be possible, but chances are
too low for a mention attm.
