Area Forecast Discussion

Updating the aviation portion of the discussion.

.SHORT TERM...(This evening through Tuesday)
Issued at 151 PM MST Mon Jan 2 2017

Currently...an upper level disturbance over northern Arizona is
beginning to move into western colorado this afternoon. Observations
and webcams indicate light snow falling along the Continental
Divide.  Dry conditions are prevailing across the Plains with
temperatures in the mid 50s.  Gusty winds exist along the lee
slopes, generally west of I-25, where gusts to 30 mph are expected.

Tonight and Tuesday...the upper level disturbance embedded in
westerly zonal flow aloft will move across the area tonight.  This
will bring an increase in snowfall to the Continental Divide through
the overnight hours.  Snowfall accumulations of 2 to 4 inches are
expected, with locally higher amounts possible.  In addition,
mountain areas will see gusty winds to near 50 mph allowing for
blowing and drifting snow.  Expect a decrease in snowfall by Tuesday
morning as the upper disturbance moves away from the area.  An
additional inch or two of snow will be possible during the day on
Tuesday.

Across the Plains, a cold front is forecast to back westward tonight
bringing increased moisture and colder air to the region.  Expect
low stratus to fill in behind the front by morning.  In addition,
sounding profiles indicate patchy light freezing drizzle may be
possible by morning.  There could be a few slick spots during the
morning commute.  Clouds will hang around for most of the day and
limited heating will keep temperatures from rising out of the 30s.

.LONG TERM...(Tuesday night through Monday)
Issued at 151 PM MST Mon Jan 2 2017

West to northwest flow aloft continues across CO Tuesday night
into Wednesday. This keeps the best chance for snow confined to
the higher elevations of central and south central colorado. Winds
will be gusty at times in the higher elevations with jet moving
overhead Wednesday afternoon and evening. Could be some areas of
blowing and drifting snow.

A vort lobe will shift south through the northern plains late
Wednesday bringing a reinforcing cold front through the southeast
plains of CO Wednesday night. Wednesday night and Thursday will
likely be the best chance of snow east of the mountains with cold
airmass in place, upslope flow, and warm, moist Pacific air aloft.
Thursday will also feature the coldest temperatures of the week
with highs in the 20s at the lower elevations.

Significant differences in the models for Friday bring lower
confidence in the forecast. ECMWF is progressive sweeping the
elongated east to west oriented trof south across the state, while
the GFS is much slower bringing the remnants of the closed low off
the Oregon coast across CO Friday into Friday night. If the GFS
solution verifies, could see additional snowfall across the plains
Friday. Models in good agreement building a ridge over the Rocky
Mountain region over the weekend and temperatures warming above
normal. Stark

.AVIATION...(For the 06Z TAFS through 06Z Tuesday night)
Issued at 1056 PM MST Mon Jan 2 2017

Cold front continues to back across the southeast plains, with
current satellite imagery indicating MVFR and IFR stratus across
northeastern and southeastern Colorado at this time. Will see
this MVFR and IFR stratus continue to push west into COS and PUB
between 07-09Z and persisting through mid morning before diminishing
through the late morning and aftenroon hours. With upslope flow
persiting, could see MVFR stratus redevelop through the evening
hours.

Latest model data continues to support VFR conditions for ALS
through the period, with enough southerly wind and clouds to keep
fog formation through the rest of night.
