.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...
(06Z TAFS)
Issued at 1003 PM MST Wed Dec 10 2025

VFR through the period with SKC-SCT250. Variable winds AOB 7
knots, becoming west/southwest 7-10 knots after 20Z.

.FIRE WEATHER...
Issued at 1043 AM MST Wed Dec 10 2025

Fair, dry, and benign weather continues, and should do so for the
next week or so. High pressure remains anchored over the west
coast, extending into the Southwest Deserts. The W and NW flow
pattern over the ridge is keeping the storm track well to our
north, and keeping dry and mild conditions over our area. This
will mean dry weather, with few clouds, and no precipitation. RH
will drop to the upper teens and 20s each afternoon, and recover
into the 50-70% range each night. Temperatures will trend a bit
warmer, and be well above the daily averages. Winds will be
generally light, with typical daytime breezes, and lighter
nighttime drainage.

Sunday we see a backdoor front push in from the plains for a day
of east winds, and some gusts. Temperatures will cool about 5 or
so degrees, but remain mild and above normal. Next week, we start
to march temperatures warmer again, as we remain under ridging.

Models are beginning to show a quick passing shortwave upper
trough to pass across the region, but it will be lacking moisture
to work with, so we will continue dry for quite a while to come.

The high pressure over the region will limit mixing heights, and
also keep winds relatively light, so ventilation will continue to
struggle, with mostly poor and fair categories dominating.
