.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 1222 AM MST Mon Dec 22 2025

Today, zonal flow will dominate the upper levels as a weak,
unorganized airmass sits over the area in the low-levels. This will
lead to pretty light winds at the surface and mostly clear skies,
allowing us to heat up very quickly. Temperatures today look to warm
into the 70s. Locations along and south of U.S. 40 and west of U.S.
83 will warm into the upper 70s, with isolated 80s being possible.
These high temperatures will likely set some records. More
information about the potential records can be found below in the
Climate section. RH values are expected to drop into the mid teens
for eastern Colorado, but the weak winds will prevent any concerns
for fire weather.

Tonight, temperatures will cool into the low to mid 30s. Light
westerly winds are forecast to keep the central (east/west oriented)
70% of the CWA above freezing. If the winds go calm for an hour,
temperatures will likely drop below freezing. There is a 5% chance
of some patchy fog over the northeastern CWA Tuesday morning with an
approaching high.

Tomorrow, around sunrise, an 850 mb high will descend over Nebraska,
leading to some CAA from the northeast. This will keep temperatures
capped in the 60s, which is still much warmer than average.
Overnight tomorrow, as the low moves off to the southeast, it will
provide some southerly flow. Temperatures Tuesday night will be
similar to tonight`s, most of the area will be in the mid 30s, but
the far northern CWA will likely cool to around 30.

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Issued at 1256 AM MST Mon Dec 22 2025

Starting the extended period Wednesday, high pressure across the
southeast expands northward leading to warm temperatures for
mid/late December standards for the area. High temperatures
continue to remain forecast in the mid 60s-low 70s. A surface
low looks to be in place across southeast Colorado which will
lead to westerly winds across the southern portion of the area
and variable winds across the north. Could see some slightly
higher temperatures than currently forecast across the southern
portion of the area due to this. Due to the proximity and more
broad nature of the low and the further northward expansion of
the high pressure overall concern for fire weather continues to
lower despite the warm temperatures and low humidity in the mid
to upper teens. Still can`t rule out some brief,isolated
pockets of wind gusts of 25 mph mainly along and south of
Highway 40 due to diurnal mixing. But with very shallow mixing
heights up to 1500 feet think any of those gusts would be few
and far between.

Another warm day is forecast for Christmas Day. A classic, almost
summer like pattern, will be in place with the high pressure across
the southern CONUS and a developing trough across the western CONUS.
Ensemble members are in good agreement with the deamplification
of the ridge across the southern CONUS which should help for
more of the WSW "furnace" wind influence on the area resulting
in highs in the mid to potentially upper 70s. There is a 5-10%
chance of elevated fire weather currently on Christmas. Have
some concerns that current forecast RH may be to high as the GFS
is a bit more bullish on moisture advection from the west with
the trough as I have a hard time believing that that much
moisture can survive over the Rockies. ECWMF still shows the
moisture advection but is lesser on the amounts. If the moisture
advection does not occur then RH may have the potential to fall
into the mid teens resulting in critical fire weather but think
that scenario currently is around 1% chance of happening.
Breezy winds gusting 30-40 mph are forecast to develop as a weak
cold front moves through the area that will shift winds to the
northwest.

Friday in wake of the front will be a little "cooler" albeit still
well above normal with highs in the 60s. Winds currently do not
appear to be as strong as pressure gradients wane but still could
some rogue gusts around 25 mph during the afternoon. The mild
temperatures are forecast to continue at least into Saturday. I
could see the high temperatures on Saturday increasing as most
ensemble guidance shows relatively the same pattern continuing.
I think the main driver for the currently cooler temperatures
is coming from the GFS which moves through a cold front quicker.
Am leaning more towards a Sunday morning frontal passage
currently based on the current ECMWF-AIFS and GEFS ensemble
members supporting this. The front has the potential to be
modest which would let temperatures fall back down closer to
normal.

Currently any precipitation chances through this period looks
unlikely but a potentially more active pattern may start to
ensue for the very latter portions (Sunday night/Monday
morning)into next week as a deeper trough may develop.
Spaghetti models still are all over the place on the timing,
location, evolution of this system however any specifics are
murky at best at this time.

.AVIATION /12Z TAFS THROUGH 12Z TUESDAY/...
Issued at 350 AM MST Mon Dec 22 2025

VFR conditions will prevail through the period for both KGLD and
KMCK. Winds throughout the day will favor a southwesterly
direction before favoring a northwesterly flow around 6Z.

Temperatures will be pretty warm today, so density altitudes
will be higher than normal for late December. Overall a good day
for the reindeer to get in some hours before the big day.
