.SHORT TERM...
(This afternoon through Monday night)
Issued at 208 PM CDT Sun Jun 8 2025
WV imagery this afternoon shows the upper ridge has shifted to
center over southwest Chihuahua. Continued increased thicknesses
and full insolation is resulting in another afternoon of triple-
digit temperatures over most of West Texas and Southeast New
Mexico. CAMs are persistent in developing convection over the next
couple of hours in two main areas--just east of the Davis
Mountains along a weak dryline, and over the northeastern zones as
a shortwave arrives late this afternoon/evening in northwest flow
aloft. Mesoanalysis already shows deep-layer bulk shear of 50 kts
over the South Plains, and CAMs develop this down along the
dryline as the afternoon wears on. CAMs and the 12Z KMAF RAOB
maintain mid-level lapse rates 8-9 C/km in place, and beaucoup
instability as surface dewpoints of 60 F or better stretch as far
west as KINK. To spice things up a bit, another rather
obstreperous MCS is on tap to graze the northeast again overnight,
pushing a cold front into the area beginning around 06Z. About
the only silver lining over the next 12 hours or so are LCLs high
enough to shrink hail on its way down, but increasing the wind
threat as a tradeoff. Depending on the evolution of the MCS and
front, convection could persist off and on northeastern zones
through morning. Another consolation overnight will be minimums a
couple of degrees cooler than this morning, at least along and
east of the Pecos.
Monday, the front pushes farther in, w/the NAM taking it to the
Presidio Valley by 00Z Tuesday. For those who prefer cooler
weather, highs Monday should come in below normal along/east of
the Pecos, and come down quite a bit to the west. Temperatures
northeast will drop by almost 20 F from today, to a ~ 5 F drop in
the Presidio Valley. During the afternoon, as post-frontal winds
veer to easterly, isolated convection is expected in the
southeast. To the northwest, POPs will begin increasing ahead of a
trough digging through the southwest CONUS and approaching West
Texas and Southeast New Mexico. Plenty of deep-layer shear will
persist, but with lower LCLs, the focus will once again return to
big hail.
Convective chances will increase Monday night as the trough
approaches, and yet another rather large MCS is in the cards, only
this one is a little farther south than tonight's, and looks to
roll out of New Mexico into our area overnight. Unfortunately, the
hail threat will persist. On a slightly more positive note, PWATS
increase to over 2 std devs above normal, so an opportunity for
(much-needed) heavy rain will be present. Also, overnight lows
will cool another 2-3 F from tonight's lows, coming within a few
degrees of normal.

.LONG TERM...
(Tuesday through Saturday)
Issued at 208 PM CDT Sun Jun 8 2025
Little changes to the overall pattern in the long term, and more
of an idea of where heavy storms may occur early this week.
Deterministic and ensemble models persist in showing convectively
enhanced troughing over the Southern Great Plains, extending
northeast into Central Great Plains and Upper MS Valley and
northern Great Lakes. WPC Surface Analysis continues to depict a
quasi-stationary front moving south from the TX panhandle and
South Plains into the forecast area, with its southward movement
modulated by storm interactions and enhanced by outflow from any
MCS farther to the northeast over north-central TX and central OK.
A dryline extending south along the 103W meridian ahead of the
cold front also persists, with NBM continuing to show humid,
easterly, upslope near surface flow. This regional wind pattern
keeps dew point temperatures in the 60s, 50s western higher
terrain. At the base of the positively titled short wave trough
closing off into an upper low over the northern Great Lakes, mid
to upper tropospheric wind maxima will pivot over the forecast
area, enhancing lower to mid tropospheric wind shear, especially
on Tuesday, when highest PoPs are apparent over the forecast area
in NBM grids.
PoPs 45% to 60% over northeast Permian Basin and 25% to 40%
extending from SE NM plains into Davis Mountains and Presidio
Valley expand in coverage and magnitude by evening to 65% to 80%
over Davis Mountains, where heating of elevated terrain will
likely initiate convection by the afternoon. High-res CAMs for
Tuesday show showers/storms moving east through E NM into Permian
Basin Tuesday morning, with clearing in their wake. Then, high-res
CAMS are consistent with NBM in showing formation of discrete
storms over Davis Mountains expanding east/southeast and another
cluster of storms forming over E NM and moving east into Permian
Basin. For now, highest reflectivity is apparent southwest of
Pecos River, where heaviest storms may set up. SPC has outlined
most of the forecast area except for the Western Low Rolling
Plains in a MRGL risk Tuesday, mentioning weak to modest deep-
layer shear atop convectively altered west-oriented outflow and a
local maximum in storm coverage over the Trans Pecos, with 5%
severe probabilities within 25 miles of any point in the hatched
severe probability area. Ensembles depict 25 to 35 knots of
surface to mid tropospheric shear over the central and southern
portions of the forecast area, sufficient for organization of
rotating updrafts capable of sustaining long-lived storms that can
generate severe weather. Forecast soundings over this region show
PWATs at least 1.30" and low-level and mid-level RH below 70%
minimizing melting of falling hailstones, and near dry adiabatic
lapse rates in the lower troposphere , mean CAPE 1500-2000 J/kg,
and DCAPE 1000-1200 J/kg pointing to an increased damaging wind
risk from large non hydrostatic motions that can mix down higher
winds aloft down to the surface. LCLs below 2000 meters and 0-3 km
SRH near or above the 80 m2/s2 threshold for tornadogenesis with
elongated hodographs and backed southeast/east winds also suggest
a nonzero tornado risk, although main risk due to storm mode
continues to be damaging winds and large hail. Highs Tuesday near
to 5 degrees below average translate to upper 70s to lower 80s
higher elevations, 80s, lower to mid 90s southeast Permian Basin
into Terrell County and southern Rio Grande basins, and upper 90s
to triple digits along the Rio Grande from Presidio Valley into
Big Bend. Shading from convective debris from previous and ongoing
storms that limits solar heating may result in some locations
over central portions of the forecast area ending up cooler than
mid to upper 80s indicated in NBM runs, with ensembles showing a
medium probability of this occurring. Tuesday night, CAA behind
the southward moving cold front results in lows near to a few
degrees below average, above average along the Rio Grande. This
translates to 60s, upper 50s Davis Mountains and surrounding
foothills as well as Guadalupes and northern Lea County, and upper
60s to lower 70s southern Rio Grande basins into Rio Grande.
Highest PoPs 45% to 60% persist over eastern Permian Basin
through the night into Wednesday morning. Wednesday morning, PoPs
again increase over eastern Permian Basin and Davis Mountains, two
regions coming into focus as having higher probability of seeing
repeated storm occurrence and severe weather impacts that are
greater than surrounding regions. However, PoPs decrease and trail
off to the east by Wednesday evening, and some high-res CAMs are
not showing much in the way of any widespread precipitation.
Additionally, wind shear will be decreasing. Therefore, forecast
sounding parameters while supportive of a nonzero severe risk,
will tend to more of a heavy rain threat before storms diminish
through the day. PWATs increase throughout the week to at or above
the 90th percentile, so we are expecting the potential for
flooding where heavy downpours in any showers/storms occur,
especially for regions over eastern Permian Basin where both NBM
and ensembles continue to show highest rainfall totals by the end
of the week. NBM has increased rain amounts into the 1.00" to
1.50" range on leeward slopes of Davis Mountains and Lea County
into central into northeast Permian Basin, up from 0.50" to 0.75"
in yesterday's runs. However, ensembles continue to depict only a
few tenths of an inch of rain at most, even with medium
probabilities over these regions of at least 0.75" of rainfall,
similar probabilities of at least 1.00" to 1.25" over easternmost
Permian Basin, and spreads ranging from 1.00" to 1.50" over Davis
Mountains and easternmost Permian Basin. Therefore, rainfall
amounts remain uncertain. Wednesday temperatures similar to
Tuesday are expected, except for a few degrees warmer basins of
Culberson County, and a few degrees cooler over Upper Trans Pecos
into Stockton Plateau. Lows similar to Tuesday night but a few
degrees warmer expected on Wednesday night.
The forecast for building ridging over the Central CONUS from
Thursday into next weekend accompanied by decreasing shower/storm
chances and a return to warmer than average temperatures as not
changed. By Thursday, PoPs above 25% will be confined to Davis
Mountains, as highs rise back near average and into the upper 80s
to mid 90s, upper 90s into triple digits along Rio Grande. These
warmer temperatures and continued dew point temperatures in the
50s and 60s F will limit radiational cooling and keep lows above
average and in the mid 60s to mid 70s, lower to mid 60s northern
Lea County and Marfa Plateau into Lower Trans Pecos. Friday,
similar theme but at least 3 to 4 degrees warmer with widespread
lower to mid 90s, triple digits Upper Trans Pecos, basins of
Culberson County, and along Rio Grande, with lows Friday night
falling into mid 60s to mid 70s. 500 mb geopotential heights above
588 decameters and 1000-500 mb thicknesses near 576 decameters
increasing to 582 decameters by this weekend will mean even warmer
temperatures next Saturday and Sunday, with a relative maximum in
highest daytime temperatures over Upper Trans Pecos and along
Pecos River into Eddy County, basins of Culberson County, and near
the Rio Grande. While just 5 to 10 degrees above average, these
temperatures combined with higher dew point temperatures will mean
heat advisory level criteria may again be reached after this
cooler and rainier weather pattern.

(00Z TAFS)
Issued at 424 PM CDT Sun Jun 8 2025
A widespread, high-based cu field is developing this afternoon,
w/convection in the lee of the Davis Mountains. Convective
chances are too low for a mention except KFST late this
afternoon/early evening. Otherwise, a 40+kt LLJ will increase
surface winds this evening, before they begin backing ahead of a
cold front. This front will be assisted by a MCS to the NNE.
Models are in some disagreement on the extent of MVFR stratus
w/the front/MCS, and the only terminals we'll commit to attm is
KHOB/KMAF. A low-based cu field is expected near the end of the
forecast period.
