.SHORT TERM...(Today and tonight)
Issued at 402 AM MST Tue Feb 5 2019

Currently...An upper trough was located over the West Coast this
morning, producing strong southwest flow aloft across the Four
Corners and into western Colorado. High elevation sites have been
reporting southwest winds gusting up to around 40 mph overnight, as
well as intermittent snow along the Continental Divide. Across the
eastern plains, a cold front backed in during the evening hours and
has cooled temps down into the 20s for most locations, but as of 3
am still had not pushes as far as Walsenburg and Trinidad, where
temps remained steady in the 40s to near 50F.

Today...There will be some patchy low clouds and light fog across
the plains early this morning due to the cold front pushing into the
area overnight, but conditions should start clearing up by midday.
The upper trough pushes east into Idaho and Nevada today, continuing
light snow showers along the Continental Divide as well as
increasing the southwest winds as the pressure gradient tightens.
Wind gusts of 45 to 50 mph will be possible this morning and
afternoon across the higher elevations as well as for the wind prone
areas along the I-25 corridor, such as the Air Force Academy, the
Arkansas River Valley through Fremont County into western Pueblo
County, and in the vicinity of Walsenburg. Though the wind speeds
are not expected to reach high wind criteria, they will still be
strong enough at times to cause some travel issues for high profile
vehicles traveling along the interstate and over mt passes. In
addition, the stronger winds will aid in the rapid spread of any
fires that do start today, so outdoor burning is not recommended. An
additional 1 to 2 inches of new snow will be possible through the
day today for spots along the Continental Divide. As for temps, look
for highs in the mid 30s to mid 40s for the high valleys, and 50s to
near 60F for the plains.

Tonight...The upper trough moves into the Great Basin tonight, and
this is when the snow is forecast to increase in intensity and
coverage for all of the mts but especially along the Divide. Decided
to upgrade the watch to a Winter Storm Warning for the Eastern San
Juans with 8 to 12 inches of new snow expected, then a Winter
Weather Advisory for the La Garitas and the mts of Lake and Chaffee
Counties, where 5 to 10 inches are possible. All these highlights
will run from 5 pm this evening until 5 pm tomorrow evening. Strong
winds aloft will continue to be an issue, and will create areas of
blowing and drifting snow and hazardous travel conditions over the
mt passes tonight. Expect low temps in the teens for the high
valleys, and in the 20s to around 30F for the plains. Moore

.LONG TERM...(Wednesday through Monday)
Issued at 402 AM MST Tue Feb 5 2019

Wednesday:

A Winter Storm Warning is in effect for the eastern San Juans and
a Winter Weather Advisory for the La Garita, Sawatch, and
Mosquito Mountains through 1700 MST on Wednesday. The trough axis
will continue to propagate over southern Colorado on Wednesday.
The associated jet streak, located south and east of the upper
level trough, has winds (around 100 kts) oriented orthogonally
over the Sangre de Cristo Mountains will cause some gusty winds,
especially over the southern I-25 corridor near Trinidad and
Walsenburg. Expect wind gusts around 45 to 50 mph. Most of the
snow will remain over the mountains, the San Luis Valley should
remain dry with the exception a rogue snow band developing. The
plains should also remain dry, but there will be a few hours
Wednesday evening when the Palmer Divide could see some light
snow.

The high temperature forecast was quite tricky for Wednesday
afternoon. The winds mentioned in the previous paragraph will force
air down the slope of the Rockies, which will create above average high
temperatures over the southeastern plains, but an encroaching
cold will keep temperatures cooler behind it. For example in
Lamar, statistical guidance has a high of 43F or 60F for Wednesday
afternoon. The verification will be determined by the speed at
which the cold front develops over the region. Right now I have
the front developing from the northeast to the southwest at 1700
MST on Wednesday. Gusty northerly winds will develop behind the
cold front, which will bring wind chill values to the single
digits over the plains during the overnight hours.

Low temperatures will span the single digits to the teens over the
plains, the San Luis Valley will be below zero, the upper Arkansas
River Valley will span below zero to single digits, and the
mountains will be below zero. Once again, there will be gusty winds
as the cold front passes, so wind chill values will be in the single
digits across the region.

Thursday:

High temperatures on Thursday will be quite chilly, expect the
plains to span the teens to low 20s, the San Luis Valley and upper
Arkansas River Valley to be in the 20s, and the mountains to only
reach the single digits.

Scattered snow showers are expected over the mountains as the broad
trough axis continues to develop easterly. Heavy snow accumulations
are not expected at this time, but continuous light snow is
expected.

Friday:

A weak ridge aloft will keep conditions dry, skies mostly clear, and
winds light over the region. High temps will be around average for
the plains and still below average for the San Luis Valley.

The Weekend:

The next storm system begins to develop over the region Saturday
afternoon. At this point in time the storms appears to be trending
towards a more progressive, quick moving shortwave, so snow is only
expected over the higher elevations. Associated with the shortwave
is a weak jet streak, which is forecast to bring some gusty winds
over the eastern plains and at ridgeline over the mountains.  There
is still plenty of uncertainty over where and how strong the
shortwave will be, so check back as we ingest more data.

Monday:

Long range guidance suggests another upper level trough will propagate
over the region. At this point, the trough is resolved to develop
over northern Colorado, which would bring snow to the central
mountains, but leave the rest of the region dry.

.AVIATION...(For the 12Z TAFS through 12Z Wednesday morning)
Issued at 402 AM MST Tue Feb 5 2019

KCOS and KPUB: MVFR to IFR conditions across the plains this morning
until around 17z due to patchy low clouds and light fog. By 17z sfc
winds shift to a more southwest to west direction and the lower
levels will mix out, producing VFR conditions. There will be some
LLWS through the morning as winds at 020ft will be strong and out of
the WSW, while at the sfc winds will be light and out of the ESE.
Will include in the KCOS TAF, but will leave out of KPUB.

KALS: VFR conditions over the next 24 hrs likely, with brisk SSW
winds forecast. Snow showers will move into the vicinity by 03z
tonight, but are expected to push into KALS until after the forecast
period. Moore

Over the mt passes, and especially along the CONTDVD, plan on LIFR
conditions over the next 24 hrs.
