Area Forecast Discussion
National Weather Service Pueblo CO
1115 AM MST Fri Dec 8 2023

.SHORT TERM...(Today and tonight)
Issued at 347 AM MST Fri Dec 8 2023

Key Messages:

- Active day today with potent short wave dropping into the region.

- Likely 2 periods of active wx, one late this AM into early
afternoon, and then a second stronger system this evening.

- Snow likely with this activity, especially the I-25 corridor
regions (note - some liquid likely this afternoon plains).

- Would not be too surprised if we had to issue a snow squall
warning(s) during this fcst period for parts of the region (Note the
impressive mesoscale circulation in hi res guidance over the Palmer
Divide early this evening).

Currently...

Per sat pix and short range model guidance, fairly sharp baroclinic
band was located over the NW CO region and was gradually pushing
southeast. Radar representation of precip was not all that sharp,
but GJT radar was showing some banding with this feature.

Temps at this hour showed some fairly warm readings just east of the
mtns in El Paso, Fremont and Pueblo counties and this was associated
with the sfc westerly flow still over the plains. Where the winds
have weakened over the plains temps have fallen into the 30s. Over
the remainder of the region, the SLV was in the 20s while the upper
Ark rvr valley (where sfc westerlies were still noted) were in the
30s. Mtns were cooling into the single digits and 10s as cold air
advection pushes in aloft.

Overview...

This weather system will come in in two pieces, the first will come
in later this AM/early PM, and the 2nd piece (with much colder air
coming in aloft) will come through this evening into tonight. Most
of the fcst area will be impacted, with the central mtns, greater
Palmer Divide region and the southern I-25 corridor region. The
Palmer Divide will likely be impacted by both pieces of energy.
Given the dynamic of this system along with short range hi res
guidance, we may see some snow squalls with this system, and these
may impact travelers on the major roadways during the next 24 hours.

Some of the hi rez guidance is showing some rather high qpf with
this system (especially this evening), and there is a chance of a
high impact event affecting parts of the region.

Today...

Impacts with the first wave will be occuring over the central mtns
early this AM and will push into the PPR region during the ~14 UTC
time frame. The tail end of the morning rush will be affected,
especially over N El Paso county. It is possible that snow squall
conditions will be possible and with temps below freezing already
could slicken up the roadway pretty quickly (The forecasted SPC snow
squall parameter starts to light-up later this AM around 14-15 UTC
over the Palmer Divide). Given the strong baroclinic forcing with
this, I do expect we will see some locally heavy bands of snow with
this system this morning (how heavy and how intense still needs to
be determined). The brunt of the first system should move out of the
PPR by late AM or early afternoon with only scattered showers
thereafter through mid afternoon. However, by late afternoon the
activity should once again pick up over the Palmer Divide as the
main short wave will be approaching the region and precip will once
again begin to pick up over the PPR.

Over the central mtns, snow will likely continue throughout the day,
and several inches are near certain (nr 100%).

Tonight...

The 2nd stronger wave will push out over the region and this will be
pushed in by a strong cold front which will barrel down the plains
later this evening (The HRRR is indicating an IMPRESSIVE mesoscale
circulation associated with this 2nd short wave moving SSE early
this evening). Expect gusty north winds with this feature and
impacts along the I-25 corridor are likely. Highest POPs with this
feature will be over the PPR during the mid evening hours (03Z0 will
push southward reaching the southern I-25 corridor region during the
early AM hours. I do expect that there will be a period of quite
heavy snow with this 2nd feature, especially along the southern i-23
corridor late tonight. For this reason, we have issued a snow
advisory for the southern I-25 corridor after midnight tonight.

It will be cold and windy (and snowy some areas) early Saturday
morning across the region. Wind chills at 12 UTC Sat will be in the
single digits and teens plains, and below zero F over the valleys
and especially the mtns.

.LONG TERM...(Saturday through Thursday)
Issued at 347 AM MST Fri Dec 8 2023

Key Messages:

- Cool and breezy Saturday with snow winding down through the
  morning.

- Seasonably cool northwest flow Sunday into early next week.

Saturday-Sunday...Upper trough continues to dig across southeast
Colorado early Saturday morning, with deep northerly flow developing
behind the passing system through the day Saturday. North to
northwest flow aloft then remains progged to moderate Saturday night
and Sunday. Latest models remain consistent with gusty northerly
gradient flow winds of 20 to 40 mph across the area on Saturday,
with winds diminishing from west to east late Saturday afternoon
and evening. Latest models also indicate ongoing snowfall across
the southern I-25 Corridor and Raton Mesa early Saturday morning to
diminish and end through mid morning, with the current Winter
Weather Advisory timing through 18Z Saturday still on track.
Otherwise, the north to northwest flow aloft will continue to
squeeze out occasional snow showers across the higher peaks across
the Central Mts Saturday and Sunday. Temperatures below seasonal
levels in 30s to low 40s across the lower elevations on Saturday
warm back to near seasonal levels in the 40s to around 50 on Sunday,
with highs in teens and 20s across the higher terrain Saturday warm
into 30s and 40s for Sunday.

Monday-Tuesday...Moderate west to northwest flow with occasional
embedded disturbances remains progged across the region through
Tuesday, keeping chances of snow showers across the higher terrain,
especially the Central Mtns, along with temperatures seasonal levels
through the period.

Wednesday-Friday...Lower confidence in the forecast for the middle
into the end of next week, as models do indicate a cutoff low
developing across the Great Basin, though struggle on details of
where it goes later next week.

&&

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1101 AM MST Fri Dec 8 2023

Active period to continue across the TAF sites this afternoon into
tonight, especially across COS and PUB. Latest radar imagery
showing a band of light to moderate, briefly heavy, snow from
around COS to just west of PUB, and near ALS. While ALS may see a
few snow showers this afternoon, think conditions will remain on
the drier side. Some possibility for additional show at ALS early
Saturday morning but with lower confidence in place, have opted to
leave out any mention at this time. For COS and PUB through mid
afternoon, expect these snow showers to continue with the lowest
vis expected to stay in the 1-3sm range. That being said, would
not be surprised to see vis briefly down to around one half mile
briefly here at the start of the period for COS. Should see a lull
in the snow activity for both COS and PUB later this afternoon,
but with additional snow developing this evening and into much of
the overnight hours. It's during this time that a longer period of
light to moderate, occasionally heavy, snow will be likely for
both sites. Little changes to the previous TAF for this time
frame, but will monitor the need to add periods with vis down to
around one half mile. MVFR ceilings develop at COS and PUB with no
real improvement until later Saturday morning. Winds will likely
be highly variable this afternoon under these snow showers, until
a shift towards increasing northerly winds occurs later this
evening.
