This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

Elevated fire danger will develop this afternoon over the Palmer
Divide and Lincoln county where gusty south winds and low humidity
levels will exist. Otherwise it will be dry and warmer today.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

A strengthening storm system is expected to move across the
region Sunday afternoon through Sunday night. Snow will increase
across the mountains Sunday afternoon and evening, and may be
heavy at times. On the plains, rain showers will develop late in
the afternoon and spread east through the evening, while also
changing to snow as temperatures turn colder. At this time, these
are the most likely snow accumulations from this storm;

Mountains and foothills: 4-10 inches with locally higher amounts.
I-25 Corridor Denver to Fort Collins: 1-4 inches, with the
heavier amounts favoring southern Denver.
Palmer Divide including Douglas and much of Elbert counties: 3-8
Eastern Colorado plains: 1-4 inches.

Snowfall amounts may be higher or lower than this as the exact
timing of changeover from rain to snow on the plains will affect
snow accumulations. Just an hour or two could make a big
difference. People planning travel across Colorado should be
prepared for slick roads and poor visibility due to locally heavy
snowfall. Snow will taper off later Sunday night into Monday

Drier and warmer weather will redevelop across the forecast area
Tuesday into Wednesday, before the mountains see more snow in the
forecast for Thursday into Friday.


Spotter activation will not be needed today or tonight.
