...Potent Winter Storm system Taking Aim on the Northern Colorado
High Country...

This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Dry, breezy and unseasonably warm weather will create high fire
danger conditions for a few hours this afternoon on the Palmer
Divide and nearby plains. The elevated fire danger should quickly
improve with darkness. Overnight, snow showers will develop in
the northern mountains this evening and become widespread after
midnight. Ridges and higher west facing mountain slopes generally
north of Interstate 70 could see up to 4 inches of wet snow by
morning, with little to no snow in other mountain areas. The
plains will remain dry and mild.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

A strong Pacific storm system sliding south across the region is
expected to bring snow, strong winds and much colder temperatures
to the high country on Friday. Snowfall in the mountains could be
heavy at times on Friday afternoon and evening. Strong gusty
winds will also produce areas of blowing snow creating poor travel
conditions. Snowfall amounts of 1 to 2 feet are expected over the
Rabbit Ears Pass area, while significant accumulations are also
possible from Rocky Mountain National Park down through Summit

On the plains, scattered rain and snow showers can be expected
with late on Friday with the passage of a strong cold front. Gusts
of 30 to 50 mph will increase over the plains by Friday evening
behind the front. Any snow accumulation should be minor and
confined to areas near the foothills and on the Palmer Divide.


Spotter activation will not be needed today or tonight.
