.SHORT TERM...
(This afternoon through Tuesday night)
Issued at 240 PM CDT Mon Jun 9 2025

An active shower/storm pattern is setting up later today into tonight,
with more showers/storms tomorrow. High-res CAMs, PoPs, NBM weather
grids, and ensemble CAPE-wind shear-reflectivity paintball show a
broken line of showers/storms over northern NM consolidating into
an MCS over central into SE NM, and moving southeast through the
Permian Basin during the overnight hours from midnight into
sunrise. This activity will be preceded by a lull in activity from
yesterday's storm that moved through central/south Midland into
Big Spring in the northeast Permian Basin. VIS/IR satellite
imagery this afternoon shows cold cloud tops associated with
overshooting in severe storms moving southeast out of the forecast
area, with partial clearing in their wake and layered clouds
moving southwest over SE NM plains and Permian Basin, and rapidly
developing, westerly sheared cold cloud tops farther to the west
and northwest over central and northern NM. Low ceilings across SE
NM plains into Upper Trans Pecos have lifted, allowing for
diurnal heating through at least filtered sunshine. Even so,
passage of a cold front southward through the area will result in
CAA offsetting diurnal heating, resulting in highs 4 to 6 degrees
below average behind the cold front northeast of Davis Mountains,
and 5 to 6 degrees above average southwest and south of Davis
Mountains into Trans Pecos. This translates to upper 70s to lower
80s northern Lea County into northernmost Permian Basin, 80s SE NM
plains into central Permian Basin, most of Culberson County into
Davis Mountains and Lower Trans Pecos, lower to mid 90s southern
Permian Basin into Stockton Plateau, Terrell County, basins of
Culberson County, and Rio Grande basins, and upper 90s to triple
digits along the Rio Grande and southernmost Rio Grande basins.
The southward advancement of the cold front will be modulated by
storm interactions and outflow from previous storms, such as the
MCS that moved across the Southern Great Plains farther to the
northeast yesterday. The southward movement of the cold front will
also be affected by a persistent short wave troughing pattern
from Upper MS Valley developing into northern Great Lakes,
stretching into Central Great Plains and down into W TX.
Deterministic and ensemble models continue to depict the trough
closing off into an upper low over the northern Great Lakes, but
have trended faster with the upper system developing east, while
maintaining enhanced westerly tropospheric winds on the back side
of the trough and ahead of another short wave trough developing
over the Desert SW. This continues to result in models imparting
35 to 45 knots of westerly shear across the forecast area today
into tonight. This will be sufficient for organization of rotating
updrafts allowing for long-lived storms capable of producing
severe weather.

NBM PoP grids show convective initiation over usual region of
elevated higher terrain over Davis Mountains where 15% to 30% PoPs
are present, moving east/southeast into Lower Trans Pecos and
Terrell County prior to the consolidating MCS later tonight. Dew
point temperatures under sustained upslope easterly winds reach 60F
as far northwest as central to northern NM today, providing moisture
and instability for thunderstorms to grow and consolidate into an
MCS. Forecast soundings ahead of this MCS and accompanying 35% to
50% PoPs farther to the northwest show CAPE 1500-1900 J/kg and CIN
up to -150 J/kg allowing for storms to both remain rooted in surface
boundary layer and maintain discrete mode and having a narrower
horizontal profile, resisting nocturnal cooling and stabilization of
boundary layer as well as upscale growth, respectively. Forecast
soundings also indicate mid-level RH below 70% and moist adiabatic
lapse rates of 5-6 C/km with low-level RH near 70%, but DCAPE 1000-
1500 J/kg, suggesting enough low-level moisture and non hydrostatic
motion for transport of higher winds aloft down to the surface in
thunderstorm downdrafts. PWATs below 1.50" and SHIP values above 1.0
with Sounding Analogs showing matches to supercell and significant
hail cases still indicate potential for large hail. 0-3 km SRH above
minimum 80 m2/s2 threshold, LCLs below 1000 meters, and backed low-
level easterly winds atop veering westerly/northwesterly winds
increasing with height generate elongated hodographs with low-level
curvature and TOR indicated in possible hazard type, so there is a
risk for tornadoes to spin up as well, with STP values above 1.0
showing potential for any tornadoes that spin up to be strong. SPC
continues to mention a mainly damaging wind and large hail risk,
citing marginally favorable mid-level winds, but agreeing with high-
res CAMS in showing thunderstorm development from heating of
elevated terrain over northern and central NM this afternoon. The
forecast area is in a 5% to 15% risk of damaging winds and large
hail in a SLGT risk area, with a risk of this occurring within 25
miles of any point in the hatched area. We will continue to monitor
how the all hazards severe risk and most probable configuration of
storm mode evolves with time. Storms are forecast to move out of the
area by sunrise with lows mid 60s to lower 70s as a result of
residual low-level clouds limiting radiational cooling, with lower
60s Marfa Plateau and over northern Lea County where less clouds and
more radiational cooling is expected, lower to mid 70s southern Rio
Grande basins into Terrell County.

Tuesday, a higher chance of rain continues to be indicated in PoP
grids, as high as 60% to 70% over Davis Mountains and SE NM plains
afternoon into evening and spreading into northeast Permian Basin by
midnight into Wednesday morning. High-res CAMS indicate a messy
storm mode over much of the area with shower/storm chances
throughout the day, with highest coverage over Stockton Plateau into
southeast Permian Basin and into Terrell County. SPC mentions MLCAPE
2500-3000 J/kg, orographic ascent, and discrete supercells in the
late afternoon over the Lower Trans Pecos, with lesser severe
wind/hail risk elsewhere, and lower confidence in upscale growth
along the Rio Grande Tuesday evening, albeit with a SLGT risk from
Culberson County into Brewster County and MRGL risk elsewhere with a
2% tornado risk, 5% damaging wind risk, and 5% to 15% large hail
risk. Forecast soundings have held the weakening shear trend - apart
from over Culberson County into Brewster County ahead of the Desert
SW trough - and shrinking hodographs, but maintain SHIP values at
least 0.5, PWATs near or below 1.50" and at or above 90th
percentile for this time of year, mid-level lapse rates 7-8 C/km,
DCAPE 1000-1500 J/kg, and mean CAPE 500-1000 J/kg with CIN at
least -100 J/kg, so uncertainty in storm severity and coverage
continues to be apparent despite high PoPs and continued
possibility of damaging winds and large hail. Locally backed
northeast winds beneath west-southwest winds increasing with
height over Davis Mountains into Lower Trans Pecos may enhance
tornado threat. With climatologically high PWATs today and on
Tuesday, flooding rain will be a risk as well. The convective
cloud debris and CAA behind the still southward moving cold front
will again offset diurnal heating, with highs 4 to 6 degrees below
average in the 80s, 90s southern Rio Grande basins into Terrell
County, and temperatures outside of the southernmost Rio Grande
basins and along the Rio Grande being more of a function of storm
coverage than latitude or meridional position with respect to the
cold front. Wednesday night, lows again fall into the 60s and 70s
as the troughing pattern eases, but will be a few degrees cooler
as the cold front and accompanying CAA will reach farther south
than tonight. Rain chances will wind down in the long term, but
rain total amounts in the short term have held the upward trend in
NBM grids, with amounts 1.00" to 1.50" where greatest storm
coverage from SE NM plains into Permian Basin and Lower Trans
Pecos into Brewster and Terrell Counties is anticipated, and
localized amounts up to 2.50" northeast Permian Basin and just
downwind of Davis Mountains. Lower percentile rain totals in
ensembles still show up to 0.3" to 0.5" in these regions and
spreads of 0.75" to 1.25", so flooding rains are a possibility
with any storms. A busy two days is ahead, but then warmer and
drier weather returns. For more on this pattern change, read on.

.LONG TERM...
(Wednesday through Sunday)
Issued at 240 PM CDT Mon Jun 9 2025

An upper-level low and associated trough axis will slowly pivot
across the Texas panhandle and adjacent portions of northwest
Texas and western Oklahoma Wednesday before gradually shifting
eastward across Oklahoma and north/central Texas Wednesday night
into Thursday. Shortwave impulses rounding the base of this
feature combined with plentiful deep layer moisture will continue
to provide a good chance (40%-60%) of showers and thunderstorms to
our region during the day Wednesday. Instability will be
sufficient for a few strong to severe storms across portions of
west and southwest Texas Wednesday afternoon and evening.
Precipitable water values will remain above climatological normals
favoring a continued locally heavy rainfall and flash flooding
with storms on Wednesday.

Some lingering moisture within northwest flow on the back side of
the departing trough axis may result in continued low chances
(20-40%) of showers and thunderstorms over the Trans Pecos and
Davis Mountains/Big Bend Thursday, with isolated (~20%) storms
possible over the Davis Mountains Friday. Upper ridging gradually
builds toward our area late this week into the weekend. Temperatures
warm back into the 90s to 100-105 degrees with dry conditions
anticipated.

.AVIATION...
(00Z TAFS)
Issued at 456 PM CDT Mon Jun 9 2025

00Z TAFs are engineered around a MCS currently moving through New
Mexico, and expected to make a right turn and roll through
Southeast New Mexico and West Texas overnight. Forecast soundings
suggest VFR conditions will prevail, except in areas of
convection. Otherwise, surface winds will slowly veer over the
next 24 hours.  Frequent updates likely.
