.KEY MESSAGES...
Updated at 442 PM CDT Tue Apr 29 2025

- Another round of strong to severe storms are expected this now
  through tonight with the primary threats being very large hail,
  damaging winds, and a tornado or two. The greatest potential
  for severe storm development will be over the northern and
  eastern Permian Basin.

- Heavy rainfall from multiple rounds of storms may lead to flash
  flooding for certain locations, with higher confidence of this
  occurring over portions of the northern Permian Basin.

- A couple of cold fronts will bring cooler temperatures to the
  area by the end of the week.

- Another storm system makes its way to our region through the
  course of the weekend, bringing daily rain chances along with
  it. Currently, it is too soon to know details about severe
  weather potential with this system.

.SHORT TERM...
(This afternoon through Wednesday night)
Issued at 255 PM CDT Tue Apr 29 2025

Southwesterly flow aloft remains prevalent across west Texas and
southeast New Mexico early this afternoon in advance of an upper-
level low spinning over the vicinity of northern Arizona. A surface
cold front has stalled over the vicinity of the southern Texas
panhandle/northern South Plains early this afternoon. A dryline
extends southward from this feature and is roughly located from the
central Permian Basin to the Trans Pecos and eastern Big Bend, or
roughly along and west of a Lamesa, Midland, Sanderson line.

Storms have already begun to fire off of this dryline. Yet again,
these storms will have the potential to become strong to severe as
they move across the Lower Trans-Pecos and Central/Eastern Permian
Basin. The primary concerns will be hail up to the size of baseballs
and damaging winds (70-80 mph for the strongest storms).
Nevertheless, a tornado threat cannot be ruled out, especially later
in the evening as the low-level jet ramps up and as the stationary
boundary enters northern portions of the area. This stationary
boundary will encourage more focused ascent during the evening and
overnight, which would allow for training thunderstorms to develop,
promoting a flooding threat for any location underneath the boundary
when it stalls. The lingering question at this point is where
exactly the boundary stalls, but as of right now guidance indicates
it will be over the northern Permian Basin. Thus, the highest rain
chances (60-90%) are for this area.

The upper-level low and associated trough axis will translate
eastward into New Mexico and far west Texas tonight and then across
the Texas panhandle and adjacent portions of west Texas during the
day Wednesday. As this occurs, the dryline will be pushed to the
east of our area, effectively terminating our rain and storm chances
at least through the rest of the short term period. Breezy
conditions will accompany the passage of the upper-level system
Wednesday.

.LONG TERM...
(Thursday through Monday)
Issued at 255 PM CDT Tue Apr 29 2025

The long-term period begins with quiet weather as a subtle ridge
moves over the region. The ridge will supply warm temperatures
ranging from the 80s to lower 90s regionwide, besides locations
along the Rio Grande reaching in the lower 100s. Areas along the Rio
Grande and Lower Trans Pecos are forecasted to have low (< 20%)
chances of rain and storms as a surface low over northern Mexico,
coinciding with a mid-level shortwave impulses providing
sufficient lift and moisture.

Friday, the subtle ridge breaks down and a mid-level shortwave
trough pushes a cold front into the region, supplying cooler high
temperatures in the mid 60s to mid 70s across southeastern New
Mexico, the Permian Basin, and higher terrain both Friday and
Saturday. Areas elsewhere span in the 80s to 90s as the cooler air
behind the front will not make it into these areas. Rain and storm
chances return as the cold front arrives in the region as shortwave
troughing persists through the weekend. There is uncertainty
about the severe weather parameters heading into the weekend.
Ensemble guidance has modest instability with weak low-level
shear. Forecast soundings again have the greatest CAPE profile in
the Hail Growth Zone region indicating a potential hail threat as
the primary threat. Again, this is too far out, thus more details
will be ironed out over the next couple of days. Cluster analysis
is still hinting at a strong upper-level low ejecting across the
Desert Southwest early next week. Ensemble guidance is in good
agreement with a strong upper low, however, the position of the
low not so much in agreement. This is something to monitor over
the next upcoming days given that this pattern signals more active
weather over the region.

.AVIATION...
(00Z TAFS)
Issued at 442 PM CDT Tue Apr 29 2025

VFR conditions will prevail next 24 hours except in areas of
direct convection. Surface analysis shows the triple point in the
northern Permian Basin, and so convection looks to impact mainly
KMAF/KHOB this evening. Confidence is too low and uncertainty too
high for a mention anywhere else. Winds will be erratic this
evening w/the front, but will veer to the west by 12Z, increasing
and becoming gusty by late morning Wednesday. Forecast soundings
develop a low-based cu field Wednesday everywhere but KFST/KPEQ.

&&

.FIRE WEATHER...
Issued at 255 PM CDT Tue Apr 29 2025

Elevated to critical fire weather conditions are expected mainly
west of the Pecos tomorrow due to the combination of 20-ft winds
and critical minRH values. ERCs remain above the 50th percentile
west of the Pecos with areas elsewhere below the 50th percentile
both tomorrow and Thursday. Fire weather concerns decrease to
elevated due to very light 20ft winds over southeast New Mexico
and for some locations along the Trans Pecos. By Friday, a cold
front brings improved minRH values and cooler temperatures.
