.SHORT TERM...(Today and tonight)
Issued at 359 AM MST Mon Nov 28 2016

Currently...

Observations and webcams show snow showers still ongoing along
the contdvd, especially across the central mtns. Some virga was
also noted across parts of the plains. Temps were relatively mild
for this time of the year, with 30s and 40s across the plains. In
the mtns and valleys, temps varied considerably, with negative
digits at the highest mtn tops to single digits to 30s in the
valleys.

Today & Tonight

Another disturbance in the NW flow will bring another round of
beneficial snowfall starting this afternoon to the contdvd,
especially along the central mtns and the west slopes of the far
Southern San Juans. Generally expect 4 to 8 inches of additional
snowfall with the brunt of it falling on the nw slopes of the c
mtns north of Cottonwood Pass. Initially, there will be quite a
bit of wind with this disturbance across all of the higher
terrain, but as the evening progresses, the winds will gradually
decrease. Most of the steady snow along the contdvd will end
towards sunrise Tuesday.

A few snow showers will likely develop across the Sangres late this
afternoon and evening. The remainder of the fcst area will generally
be dry.

It will be quite breezy/windy today over most of the region, with
winds on the plains in the 20-30 mph range. The winds will decrease
late this afternoon and into the early evening. The only area which
may see less wind today will be El Paso county.

Min temps tonight are expected to be a few degrees cooler than this
morning`s lows, with readings expected to drop into the 20s
across most of the plains and mainly single digits across the mtns
and high valleys. /Hodanish

.LONG TERM...(Tuesday through Sunday)
Issued at 359 AM MST Mon Nov 28 2016

...Lower Temperatures Ahead...

Tuesday and Tuesday night, upper trough axis forecast to move east
of our area, so expect precipitation to wane, and temperatures to
be colder than Monday`s readings with the push of colder air from
the north. Highs will only be in the mid 30s to mid 40s plains,
20s and 30s high valleys and teens and 20s mountains.

Wednesday, dry conditions should prevail in between weather systems,
and it will be quite cold, with temperatures just a bit below
Tuesday`s readings and below the seasonal norms.

Thursday and Friday, as we progress through Thursday, models prog the
Great Basin trough to take shape and by afternoon, moisture
increases across western Colorado and some snow develops across
the Continental Divide. As the system drops south across Utah,
some upslope flow develops across eastern Colorado Thursday night
and continues for Friday, which may bring some snow to the eastern
mountains and adjacent terrain.

Friday night through Sunday, the upper low over the southwest US is
forecast by both the GFS and European to move south into the Baja,
which puts Colorado int between the northern jet and the upper low.
So, the weather should quiet down and temperatures should moderate
into and during the weekend.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1047 AM MST Mon Nov 28 2016

A Pacific storm system will drop southeast across the flight area
this afternoon through tuesday. This system will spread widespread
MVFR...IFR and LIFR conditions across the Continental Divide with
scattered such conditions over the mountain ranges farther east.
Mostly VFR is expected across the plains as the system moves
through but a spotty MVFR...IFR...LIFR cannot be ruled out. This
includes the KCOS...KPUB and KALS TAF sites.
