.SHORT TERM /THROUGH TONIGHT/...
Issued at 155 PM MST Tue Dec 9 2025

Breezy to windy across the area today, especially higher
elevations of the central mountains, where winds continue to
gust 40-55 kt from Monarch Pass northward. Lower elevations have
seen less wind, though gusts in usual gap flow regions around
Walsenburg have been in the 30-40 kt range, with up to 30 kts
around Pueblo. Despite rather thick wave cloudiness, temps have
soared to well above average readings at many locations, with a
few spots over the far southeast plains reaching 70f.

Tonight, winds will gradually decrease at most locations as
flow aloft lessens, though still some 40-50 kt gusts possible
over the higher terrain, especially north of Highway 50. On the
plains, a weak cold front will turn winds nly early, then light
easterly by sunrise on Wed. Still enough wind and wave
cloudiness around to keep min temps milder than average at many
locations, though weakening downslope gradient will allow lee
slope locations to drop slightly colder than last night, with
most spots at/below freezing. On Wednesday, generally cooler
with less wind, though still enough flow aloft to keep higher
terrain at least breezy, with gusts 30-40 kts possible over the
higher peaks, again mainly north of Highway 50. A few snow
showers possible central mountains through the day, though any
accumulations look minor at best. Max temps will run some 10-15
deg cooler on the plains with less mixing and mid-level cooling,
while over the mountains/valleys, little change is expected,
with readings within a few degrees of Tues maxes.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 243 AM MST Tue Dec 9 2025

Wednesday Night - Monday: For the rest of the long term period,
quiet weather continues for south central and southeastern Colorado.
Synoptically, northwest flow will remain in place through Sunday,
with a brief break in the northwest flow Monday as a weak wave
drifts across the region. Overall, confidence is high to very high
in this pattern (80-90%) given strong and consistent agreement
between ensemble model guidance. With that all said, forcing is
still expected to remain minimal, even with the wave passage, and
given this, dry conditions are anticipated to prevail. Beyond all of
that, breezy conditions will persist along the mountains with
lighter winds for the lower elevations, and mid to high level clouds
continuing as well. As for temperatures, much of the area will hover
around seasonal values. With that said though, a weak shallow cold
front may influence the region later in the week, but confidence is
only medium (40-50%) in how much this will ultimately drop
temperatures for the area.

period of easterly flow early, followed by a switch to gusty nw
winds around 20z-22z. Surface winds weaken and turn more nly
overnight into Wed morning, with a period of llws 01z-09z, as
