...WINTER WEATHER ADVISORY FOR MOST OF THE PLAINS AND FRONT RANGE
MOUNTAINS AND FOOTHILLS LATE TONIGHT UNTIL MIDNIGHT SATURDAY
NIGHT...

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

.DAY ONE...Today and Tonight

After a mild day, areas of light freezing drizzle and light snow will
move into northern Colorado behind a cold front late tonight. The
freezing drizzle will likely produce slick roads, with bridges and
overpasses most susceptible to icing. Pedestrians should also be
aware of slick sidewalks, driveways, and stairs.

Snow accumulations of an inch or two are possible in the Front
Range north of Interstate 70, with only a dusting possible in the
lower elevations by daybreak.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Light freezing drizzle, mixed with light snow, will likely
continue across the plains and portions of the foothills Saturday
morning. The mixed precipitation is expected to change over to
all snow from north to south across the area during the day, first
near the Wyoming border by mid morning and then into the Denver
area by mid afternoon. Snow will then continue into Sunday evening
before tapering off and ending by or shortly after midnight.
Precipitation amounts will be light, but hazardous winter driving
conditions can be expected especially early Saturday morning and
then again late in the afternoon and Saturday night. Pedestrians
should also use caution and be aware of slick sidewalks,
driveways, and stairs.

Temperatures will be well below seasonal readings on Saturday,
with a gradual warmup to above normal temperatures by the middle
of next week.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
