...Winter Storm Heading for Colorado...

This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Winds will gust as high as 65 mph over the higher elevations of
the Front Range today. Gusts in the 30-45 mph range can be
expected over the rest of the mountains and foothills this
afternoon. The plains will see near record high temperatures in
the 60s to lower 70s.

There will be elevated fire danger over the Palmer Divide this
afternoon with low humidities and wind gusts in the 10 to 20 mph

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

A Pacific storm system will begin producing rain and snow showers
over the mountains and high valleys of north central Colorado
Saturday afternoon. By evening with falling temperatures,
high country showers should quickly change over to snow where it
may become heavy at times overnight through Sunday morning.
Significant snow accumulation is possible, especially on the high
mountain passes and up around the Eisenhower Tunnel.

East of the mountains, rain and snow showers should first form
along the Interstate 25 corridor Saturday evening, before
spreading out across the plains. The rain and snow will quickly
change over to all snow by midnight after passage of a cold
front. Snowfall is expected to continue on the plains and over the
Palmer Divide through Sunday. Gusty northerly winds may also produce
areas of blowing snow during the afternoon, especially east of
the I-25 corridor. Snowfall should gradually end from west to east
Sunday afternoon into Sunday evening.

At this time exact snowfall accumulations are uncertain, however,
hazardous driving conditions will likely develop in the mountains
by Saturday evening and then spread across the northeast plains
late Saturday night into Sunday.

Weather conditions will improve late Sunday night into Monday as
the storm system moves east of the area.


Spotter activation will not be needed today or tonight.
