Area Forecast Discussion
National Weather Service Pueblo CO
1117 AM MST Sat Jan 7 2017

.UPDATE...
Issued at 1115 AM MST Sat Jan 7 2017

We issued a winter storm watch for the contdvd sun-nite thru mon-
nite. Also refreshed short term NDFD.

UPDATE Issued at 1003 AM MST Sat Jan 7 2017

Expired wind chill warning and updated gridds to account for
current conditions.

&&

.SHORT TERM...(Today and tonight)
Issued at 449 AM MST Sat Jan 7 2017

With an upper level ridge over the area today, the weather will be
dry acrs southeast and south central CO.  Temps today will still be
below average.  Highs temps forecast for today could be challenging
with the snow cover.  Will stay on the cool side of guidance and
maybe a little below in some areas.

Tonight a disturbance will move into CO and is expected to bring
some snow to the Continental Dvd, but accumulations will be light.
The rest of the area will remain dry tonight.  Westerly winds
increase ovr the mtns and nearby lower elevations tonight and this
will help keep temps a little warmer in these locations.  Some cloud
cover tonight will help keep temps in many locations from being as
cold as they are this morning.

.LONG TERM...(Sunday through Friday)
Issued at 449 AM MST Sat Jan 7 2017

...Another round of strong winds and ContDvd snow Monday and
Tuesday...

Sunday-Tuesday...Moderate west to northwest flow aloft across the
region Sunday as an embedded short wave translates across the
northern Rockies. West to southwest flow aloft increases across the
region Sunday night with strong westerly flow aloft expected across
the area Monday through Tuesday, as a strong eastern Pacific jet
stream translates across the central Rockies. Passing northern
Rockies wave brings snowfall of 1 to 4 inches to the higher
elevations of the central mountains through the day Sunday, with
some light accumulations possible across the rest of the ContDvd.
Downslope flow helps to warm temperatures back to at and above
seasonal levels on Sunday, though will likely see strong inversions
in place across the San Luis Valley keeping temperatures from
warming much.

Latest models continue to indicate ample available moisture
spreading into the region late Sunday night, and with increasing
orographic flow and UVV associated with the passing jet, should see
snow increasing along and west of the ContDvd into Monday morning,
with heavy wind driven snow at times, continuing through Monday
night into Tuesday morning. With that said, will likely need winter
storm watches for the higher terrain of the ContDvd in the near
future, with another 1 to 2 feet of snow possible.

Across the rest of the area, windy to very windy conditions will be
possible, especially over and near the higher terrain. Latest models
x-sections are indicating the potential for strong and damaging
downslope winds across the lower eastern slopes of Rampart Range and
the Wet and Sangre de Cristo mountains late Sunday night through
Monday morning, with a mtn top stable layer and reverse shear aloft.
Will need to continue to monitor future model runs for the possible
addition of a high wind watch for this timeframe as well. Gusty
westerly winds expected to continue across the higher terrain and
spread across the eastern plains Monday night as a bora front
continues to move area. The downslope winds will also lead to at to
well above normal temperatures across the area on Monday, with
slightly cooler temperatures Tuesday behind a passing bora front.

Wednesday-Friday...Lower confidence in this period of the extended
forecast as latest models differ on strength and location of more
Pacific energy moving across the region. The GFS is further north
and more progressive with energy moving across the region where as
the ECMWF is slower and digs more energy south across the Desert SW
and southern Rockies. At any rate, stayed close to model consensus
which keeps good chances of snow across the ContDvd Wednesday and
Thursday, with slight pops spreading east across the plains on
Friday. Temperatures look to stay at or above seasonal levels
through the period, with a possible cool down on Friday.

&&

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1003 AM MST Sat Jan 7 2017

ALS... Winds will remain light and variable for the forecast period,
a cirrus deck is likely to stick around through 06Z tonight. Low
level saturation and variable winds are in favor for low-level
cloud development around 10Z... This is quite uncertain as there
is very little water vapor in the air. If the low level clouds
develop, MVFR conditions would be met. Other than that brief
period of MVFR, expect VFR throughout the forecast period.

COS... Higher cloud deck will be persistent throughout the forecast
period, slightly dissipating around 08Z tonight. Diurnal wind shift
expected around 05Z.  VFR conditions throughout the forecast period
is expected.

PUB... Upper level clouds expected throughout most of the forecast
period... turning to FEW around 11Z.  Diurnal wind shift expected at
04Z tonight. VFR conditions throughout the forecast period.
