.SHORT TERM...(This evening through Wednesday)
Issued at 240 PM MST Mon Jan 23 2017

Gusty south to southwest winds will continue into the evening hours
but will then diminish.  Many lower elevation locations will see
southwest to westerly winds overnight, mainly under 15 mph, although
locations closer to the southern border will likely continue to see
gusts of 20 to 30 mph thru the night.  The mountain areas will also
continue to have windy conditions causing areas of blowing snow,
especially along the Continental Dvd.

Until around midnight or so, periods of heavy snow are expected to
continue along the Continental Dvd, with several additional inches
of accumulation.  It is also expected that the higher elevations of
the Sangre De Cristo mtns will see periods of snow and a few to
several inches of accumulation.  It also looks like scattered snow
showers will be found over the San Luis and Upper Arkansas River
Valleys this evening, which could result in some accumulation.  The
Pikes Peak area will also see the potential for some scattered
showers this evening, but nothing significant is expected.  A few
showers may also move out over the I-25 corridor this evening.

An upper low will be slowly tracking eastward acrs WY tonight and
after midnight the central CO mtns and the La Garita mtns should see
decreasing chances for snow.  However, the San Juan mtns and the
southern Sangres should continue to see periods of snow with a little
more accumulation.  Early Tue morning the sfc winds over the sern
plains will be southwest ot west and breezy or windy.  Then as the
upper low continues moving east southeastward from WY and acrs NE on
Tue, the sfc winds over the sern plains will become northerly in the
mid morning to early afternoon hours, and will fairly strong.
Unsettled conditions will continue Tue and Tue night over the mtns
areas with areas of snow and some generally light additional
accumulations. Some showers are also possible along the I-25
corridor.  Temps Tue will be cooler Tue, especially over the sern

For Wed, northwest flow aloft and some lingering moisture will
likely lead to scattered snow showers over many of the mountains
areas, but accumulations are not expected to be significant.  Temps
on Wed will still be cool, with highs in the 20s in the high valleys
and 30s acrs the plains.

.LONG TERM...(Wednesday night through Monday)
Issued at 240 PM MST Mon Jan 23 2017

Wednesday night-Friday night...Cool northwest flow aloft continues
across the region Wednesday night with flow aloft becoming more
northerly Thursday night into Friday behind one last embedded short
wave digging across the Great Basin. Pattern keeps chances of snow
across the higher terrain, mainly the central mountains, through the
day Friday before drier air moves into the region. Any snow
accumulations will generally be light and confined to the higher
peaks, with a few inches possible through out the period. Cool
northwest flow with a re-enforcing surge of cool air Thursday night
will keep temperatures below seasonal levels through the period,
with highs in the mid 20s to mid 30s across the lower elevations and
single digits and teens at the peaks. Lows look to be mainly in the
teens across the lower elevations and in the single digits above and
below zero across the higher terrain and high mountain valleys.

Saturday-Monday...Northerly flow aloft moderates across the region
and becomes more west to northwest into early next week, as a large
upper level ridge building across the West Coast and into the Great
Basin this weekend, flattens across the Rockies into early next
week. This pattern suggests generally warm and dry conditions across
the region for the weekend, temperatures warming back to above
seasonal levels into early next week.
