...WINTER WEATHER ADVISORY LATE TONIGHT THROUGH TUESDAY MORNING
OVER THE I-70 MOUNTAIN CORRIDOR, SOUTHERN FOOTHILLS, WESTERN AND
SOUTHWESTERN METRO AREAS AND THE PALMER DIVIDE...

This hazardous weather outlook is for northeast and north
central Colorado.

.DAY ONE...Today and Tonight

A storm system will move into the Great Basin today and then
move into Colorado tonight. Ahead of the system gusty southwest
winds over the Palmer Divide will produce elevated fire danger
this afternoon. Meanwhile there will be isolated to scattered
showers and possibly a few thunderstorms over the higher terrain
this afternoon.

For tonight, snow will increase in the mountains late this evening
and continue overnight increasing in intensity towards morning.
Across the plains rain will develop after midnight and gradually
change to snow toward morning. A southwest-northeast oriented band
of higher snowfall rates is expected to form over the area
stretching from the mountains out onto the plains. The exact
location is not known, however the best chances is from near the
I-70 corridor in the mountains out along or south of the I-76
corridor on the plains.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Snow will continue across most of the area Tuesday morning. There
is high confidence that several inches of snow will accumulate
over the I-70 Mountain Corridor, foothills and metro areas west
and southwest of Denver, and the Palmer Divide. Plan on slow and
slippery travel conditions for the Tuesday morning commute.
Expecting only 2-5 inches of snow around the metro areas, however
most of this will likely fall within a short amount of time around
the morning commute, resulting in potentially hazardous driving
conditions. Around a foot of snow may accumulate in the higher
terrain north of I-70, especially the Vasquez Mountains and Indian
Peaks. Snow will then end from north to south across the area
from late Tuesday morning through the early afternoon hours.

Wednesday, winds will be strong in the Front Range mountains and
foothills with gusts of 40 to 50 mph possible. This will likely
cause periods of blowing snow in the mountain areas with high snow
accumulations.

Thursday, another system may bring colder temperatures and a
chance of light snow.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
