...BLIZZARD WARNING IN EFFECT FAR NORTHEAST COLORADO THROUGH
MIDNIGHT...
...WINTER STORM REMAINS IN EFFECT FOR THE REMAINDER OF NORTH
CENTRAL AND NORTHEAST COLORADO...

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

.DAY ONE...Today and Tonight

Snow will be widespread across the mountains and plains of
northeast Colorado today. The heaviest snow will shift from the
mountains this morning out onto the plains by this afternoon.
Winds will also be increasing on the plains through the afternoon
with blizzard conditions expected east of a line from Sterling to
Limon this afternoon and evening. Wind speeds of 25 to 35 mph will
be common on the plains this afternoon, with gusts up to 50 mph
over the far eastern plains. These winds will create blowing and
drifting snow with visibilities less than a half mile at times.
The developing blizzard conditions may cause road closures.

Storm total snowfalls in the mountains are expected to be 8 to 12
inches, with localized amounts up to 18 inches. On the plains,
accumulations will range from 5 to 10 inches, with the lighter
amounts expected in eastern Larimer County and the heavier
amounts to the south and east of Denver.

Improving conditions are expected to spread from west to east
across Colorado tonight as snow comes to an end and the gusty
winds diminish.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Light snow will be possible in the northern mountains late Monday
through Tuesday. Otherwise, dry conditions are expected through
Thursday. A Pacific storm system may bring a round of snow Friday
with the best chance for snow over the mountains.

.SPOTTER INFORMATION STATEMENT...

Snowfall reports will be appreciated.
