1024 AM MST Tue Dec 12 2023

.SHORT TERM...(Today and tonight)
Issued at 412 AM MST Tue Dec 12 2023

Key Messages:

 - Increasing chances (20-40%) for light snow showers across the
   higher terrain late tonight.

Relatively quiet early this morning across the region, with a trend
back towards southwesterly flow aloft in place. As this has been
occurring, overall column has been drying with the latest RAP
analysis showing moisture shifting to the north. This will help to
limit any snow development over the higher terrain, especially during
the day today. Will see a fair amount of mid/high clouds remain in
place today and help support more below normal temperatures. Did
keep slight chance to low chance pops in place over the higher
terrain later tonight into early Wednesday morning, when guidance is
showing returning moisture across the region. This still looks to be
rather limited though, with limited snow production/accumulation
appearing likely.

.LONG TERM...(Wednesday through Monday)
Issued at 412 AM MST Tue Dec 12 2023

Key messages:

- Widespread snow showers Wednesday through Thursday, mainly over
southern mountains and plains, with potentially a significant amount
of precipitation for the southeastern plains.

- Temperatures will be below the seasonal average through Saturday,
with a rebound thereafter through early next week.

Detailed discussion:

Wednesday through Thursday...

A large building ridge over Canada is going to force a longwave
trough over the northwestern states to become cut-off by early
Wednesday as it continues to dive southward over the Great Basin
Region. Deterministic models are relatively close in agreement,
although with it being a cut-off low, a slight variation in the
overall longwave pattern could result in a shift in the track and
produce a different outcome with respect to QPF amounts as it
continues to slowly advance towards the area. At around midnight on
early Wednesday morning, the GFS has the U/L low closed off at the
500 mb level a little further north than the ECMWF and Canadian
models. The NAM12 is closer aligned with where the GFS has the low
positioned. The GFS does appear to catch up more to where the low is
positioned by the ECMWF by later in the day. All models eventually
put the position around 150 miles south of the Four Corners area by
early Thursday morning, and then with nearly a direct easterly
track, at the NM/TX border by late Thursday evening. The GFS keeps
the low closed, as well as the NAM12, though slightly further to the
north. The ECMWF is showing the U/L low being at nearly the same
location as the GFS, although it becomes an open wave. The Canadian
also has the closed low becoming an open wave, although slightly
further to the north.

Depending on which model verifies, a more northerly track could
result in much higher QPF values over the southeastern plains. There
will be enough warm air advection that might allow for some of the
snow showers to be mixed with rain near the KS border. The initial
convective wave moving through with higher PVA moving overhead may
produce a band of moderate to heavy snow by Wednesday afternoon over
the southern half of the CWA. Depending on where this materializes,
it could put down very heavy amounts of snow over the areas of the
southern mountains and plains. This could affect portions of the
southern I-25 corridor during the evening commute on Wednesday.
There will be a substantial amount of warm air advection, which
could raise snow levels over the eastern plains, so there could be
areas that have snow mixing with rain or changing over to all rain
depending on how much WAA occurs. Some of the soundings suggest all
rain for Springfield from Wednesday night through Thursday, while
other models have a transition over to snow by around 10 PM
Wednesday evening. There could just be a mix and very limited snow
accumulation as a result, but the exact snow level is the challenge
and could produce a completely different outcome in the way of snow
amounts over Baca County if they over-perform. The uncertainty lies
within how much the WAA causes snow levels to rise.

Due to many locations in Las Animas County being high enough in
elevation for precip to be predominantly snow, there could be some
locations that receive 6 inches or more through late Thursday
evening. Given the instability, it cannot be ruled out for there to
possibly be some thundersnow, especially over the San Juan and
southern Sangre de Cristo Mountains. For these locations, a foot of
snow or more will be possible. The majority of the higher QPF will
remained confined to south of US-50, although if there is even a
slight shift in the track more northward, there could be much higher
snowfall totals to the north of US-50, mainly over Kiowa County.
Again, this will all be depended on snow levels and if it gets cold
enough to transition over to snow completely by late Wednesday
evening. There will be some cold air advection as the system begins
to wrap up as it moves out over the plains, which will keep high
temperatures stuck in the 30s over the plains in Wednesday, perhaps
some low 40s for Baca County. It will be even slightly colder for
max temps on Thursday over the plains, running about 10 to 15
degrees below the seasonal average.

Friday through Monday...

A few lingering snow showers could be over the far eastern plains
early in the morning on Friday, but will continue to move out as the
U/L progresses further eastward and allows high pressure to build
back in. Northerly flow will keep temperatures cold on Friday,
especially for the plains, with temperatures around 10 to 15 degrees
below the seasonal average.

Ensembles display a ridge building back in over the inner mountain
west as the U/L low continues to exit the region. This will allow
for a return of drier conditions, with a rebound in temperatures by
this weekend and through early next week. Temperatures will remain
below the seasonal average through Saturday, but then be back above
average from Sunday through Monday.   -Stewey
