This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...Today and Tonight

A developing storm system will spread snow into the mountains late
this afternoon through this evening as an upper low intensifies
over the Four Corners region. Rain and snow will then spread
southward from the Palmer Divide into the southeast plains this
evening through the overnight hours as the storm moves slowly
across New Mexico overnight. This system has much colder air
associated with it than the past several storms and a quicker
change over to snow is expected this evening along the I-25
corridor, with rain changing to snow across all of the southeast
plains by early Saturday morning. The heaviest snow is expected to
impact the southeast mountains and I-25 corridor tonight with
deteriorating travel conditions expected into Saturday morning,
particularly south of highway 50. Gusty north winds 20 to 30 mph
will cause areas of poor visibilities in blowing snow. Tree
damage and power outages will be possible due to heavy wet snow
accumulation on leafed out trees and cold surfaces.

The track and strength of this storm system is still vulnerable to
change over the next 24 hours and snowfall amounts are vulnerable
to change, particularly across the southeast plains. If you have
travel plans across southern Colorado please check the latest
forecasts. Some areas may see difficult to impossible travel
conditions by late tonight.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

A vigorous storm system is expected to impact the region with
snow, heavy at times, in combination with gusty north winds from
Saturday into Sunday morning. Numerous winter weather warnings,
advisories and watches have been issued for southern Colorado.
Although the storm track is uncertain, particularly as it lifts
northeastward into the central plains on Sunday, some preliminary
snowfall estimates are for 6 to 12 inches for the central
mountains, Pikes Peak and northern El Paso county, with 4 to 8
inches and locally up to 1 foot for the southwest mountains. The
San Luis Valley could see 2 to 4 inches with up to 6 inches along
the valley edges, particularly in the southern portions of the
valley. However, the heaviest snowfall amounts will impact the
Wet Mountains and Sangre De Cristo mountains where 8 to 15 inches
will be possible with locally up to 2 feet possible along the
northeast facing slopes. The southern I-25 corridor and Northern
Raton Mesa region will see between 8 and 14 inches.

Considerable uncertainty remains concerning snowfall totals for
the southeast plains from Pueblo eastward to the Kansas border.
Temperatures on Saturday will hover around or slightly above
freezing, and residual warmth in ground and pavement surfaces may
lead to some melting at times. However the potential for heavy
snowfall rates, along with strong north winds gusting to 40 mph
may lead to downed tree limbs and power lines due to snow loading.
Travel may also be adversely impacted due to poor visibilities in
blowing snow along with slushy or snow covered road surfaces at
times. And the potential exists for this to be a prolonged event
with the storm now advertised to depart Sunday morning. Overall
snowfall amounts of 6 inches or more will be possible across the
plains with the heaviest amounts south of highway 50. Please
continue to monitor the latest forecasts, warnings and advisories
for the latest information.

Colder air with this storm will also lead to below freezing
temperatures across most of southern Colorado this weekend. If you
have tender vegetation outside make plans to bring them indoors
or protect them.


Weather conditions that meet reporting criteria for spotters will be
likely across all of south central and southeast colorado tonight.
