.SHORT TERM...
(Today through Sunday afternoon)
Issued at 314 AM CDT Sat Sep 13 2025
Current radar shows weak echoes approaching Eddy and Culberson
counties this morning from an approaching upper level trough over
the western United States. Instability and shear increase over
southeastern New Mexico throughout the day though models show
these values will be very marginal for any type of severe weather
activity. Therefore general showers and thunderstorms are expected
and will keep an eye out for one or two outliers that could become
strong. The convection should slowly spread east into the Permian
Basin overnight and into Sunday as the upper trough reaches the
northern Great Plains. Activity is expected to diminish as it
moves east as the upper low begins lifting northeast taking the
best lift away from our area. The best chance for accumulating
rainfall amounts will be in southeastern New Mexico and the upper
Trans Pecos down to the Big Bend while areas farther east will
struggle to see a tenth of an inch. The increasing clouds and
showers will keep highs in the 80s to near 90 degrees.

(Sunday night through Friday)
Issued at 314 AM CDT Sat Sep 13 2025
Rain chances continue in the Guadalupe and Davis mountains on
Monday despite a more stable atmosphere due to help from
orographic lift. Other lower elevation areas see their rain
chances drop off with no chance for rain the remainder of the
week. Global deterministic long range models show various
solutions that indicate there could be a chance for rain later in
the week from a weak short wave trough but timing, strength, and
location are so varied these rain chances are not shown in the
ensemble model guidance. A persistent weak upper high in place
over West Texas next week prevents much variation in temperatures
with the 80s to low 90s repeating each day.

VFR conditions prevail at all terminals. Showers with some embedded
thunderstorms are forecast to move across southeast New Mexico and
the northern Permian Basin during the day Saturday. Confidence is
low in exact timing and positioning of this activity. As such, have
opted to include -TSRA PROB30s for CNM, HOB, PEQ, and INK. These
sites have the highest chances of seeing shower and thunderstorm
activity. Shower and thunderstorm chances will continue until at
least midnight Sunday. Amendments will be made if needed.
