...DENSE FOG EASTERN PLAINS EARLY THIS MORNING...
...SNOW SHOWERS AND BLOWING SNOW MOUNTAINS...

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

.DAY ONE...Today and Tonight

Light to moderate snow will continue over Rabbit Ears Pass through
this afternoon along with blowing snow continuing into the early
evening. A Winter Weather Advisory covers this area until 5 PM MST.
This system will push eastward which will increase northwesterly
wind.

Areas of fog will continue throughout the far eastern portions of
the plains through 8-9 AM. Visibility will be down to just a few
hundred feet in spots, mainly along and east of a line from Limon
to Akron to Sterling.

Additionally, near-critical fire weather conditions could occur
across the plains as strong northwesterly flow brings wind gusts
up to 30-40 mph which could lead to rapid fire spread if a fire
were to start. Peak gusts near 60 mph can be expected in and
immediately next to the foothills. Relative humidity percentages
remain above 20 percent for majority of the region do not meet
Red Flag criteria, but spotty 14-17% relative humidity could
occur in southern Lincoln throughout this afternoon.

Drier conditions and decreasing winds are likely overnight.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Light snow and gusty winds will redevelop in the northern
mountains Friday afternoon, with gusty winds spreading down the
foothills and onto the nearby adjacent plains and Wyoming border
area Friday night. Peak gusts will likely reach 50-60 mph or more
in some of the wind prone areas of the foothills and higher
mountains. Snow accumulations are expected to be a couple inches
or less, and almost all north of the I-70 Corridor.

Dry and warmer conditions will prevail this weekend.

A potent storm system is expected to move into the region early
next week. While the greatest risk of significant travel impacts
is to our north, a slight southern change to the track could mean
more significant impacts to portions of northeast Colorado Monday
night through Tuesday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
