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

.DAY ONE...This Afternoon 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. Isolated thunderstorms will be
possible over the eastern plains late this afternoon, with
lightning and wind gusts to 50 mph the main storm threats.

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. 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. 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 along
northeast facing slopes. Over the plains and I-25 corridor, areas
around Pueblo and Colorado Springs as well as locations north of
Highway 50 will see 4 to 8 inches by Saturday evening, while the
plains south of Highway 50 and the southern I-25 corridor see
heavier snow, with 8 to 14 inches expected by early Sunday
morning. Storm total 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. Much of Fremont county will see snowfall
in the 4 to 8 inch range.

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.

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.

.SPOTTER INFORMATION STATEMENT...

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