.DISCUSSION...
Issued at 1003 PM MST Wed Dec 10 2025

Large scale picture remains mostly unchanged as upper high
persists over eastern Pacific and/or northern Mexico through the
mid portion of next week. Upper ridge strongest through Saturday
with very few if any clouds, allowing temperatures to warm well
above normal, some 10-15 degrees above seasonal averages.

Next developing Canadian upper low rides over the top of
aforementioned ridge Friday and Saturday, eventually reaching the
Great Lakes region. This produces a moderate north/northwest flow
aloft, resulting in strong pressure surge down the central Plains
and Front Range of the Rockies. This will bring some breezy winds
to west slopes of terrain such as the Guadalupe, Hueco, Franklin
Mountains early Sunday morning, and eventually out to Luna and
Hidalgo Counties by Sunday afternoon. Expect some gusts up to 30
mph during this period. Decent cold advection with 850mb temp
changes suggesting cooling of 10 degrees or more from Saturday to
Sunday, though various MOS outputs show less cooling. It remains
to be seen yet whether this front can generate low cloudiness
andor drizzle along the east slopes of the Sacs. Low-level RH
fields on models show this potential Sunday morning but a little
early yet to make that call.

Monday through Wednesday...non-impactful pattern continuing,
though the GFS/ECMWF both show weak upper low cutting through the
ridge and across the CWA Monday night/Tuesday morning. Little or
no moisture with this feature. Temperatures recovering back to
well above normal Tuesday and Wednesday.

.AVIATION...
(12Z TAFS)
Issued at 425 AM MST Thu Dec 11 2025

VFR conditions to prevail with light winds.

&&

.FIRE WEATHER...
Issued at 425 AM MST Thu Dec 11 2025

A regime of northwesterly flow aloft will foster dry conditions
and typical afternoon breezes for a majority of the forecast
period. MinRH this afternoon will settle in the 20 percent range
most areas amongst light, terrain-influenced winds. Conditions
will dry further on Friday, with critical RH favoring the Gila NF,
spreading in coverage to the east slopes of the Sacs and their
adjacent highlands on Saturday.

A backdoor front will arrive Saturday night into Sunday, shifting
winds easterly and bringing an influx of moisture. Sunday minRH
will stay in the 20 percent range for central and western zones
but zones further east will see afternoon RH in the 30 to 40
percent range. Winds are likely to become gusty with and in the
wake of the front on Sunday, with gusts as high as 35 MPH across
the eastern high terrain. Higher humidity will stick around
Monday before a stout drying trend takes hold. Tuesday will see
critical RH return to portions of the Gila and Sacs, increasing in
coverage to nearly all lowland zones on Wednesday.
