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

.DAY ONE...Today and Tonight

Snow showers will increase in the mountains by early afternoon and
continue tonight. The heaviest snowfall will focus north of the
I-70 Mountain Corridor with an impact to roadways especially
tonight.  Across the plains, a few high based showers may occur
this afternoon and evening. These showers may produce brief gusty
winds but little rainfall.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Snow increases in the mountains later Tuesday into Wednesday.
There will be a few more rounds of snow for the mountains end of
work-week through the weekend. More snow will likely fall with the
Wednesday event in the mountains which may yield travel impacts
from snow covered roads and areas of blowing snow. It will also be
windy Wednesday, especially over the Palmer Divide and Lincoln
County. Gusts up to 50 mph in areas will lead to areas of blowing
dust and elevated fire weather conditions (south Lincoln co.).

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
