...MOUNTAIN SNOW WINDING DOWN THIS EVENING...
...WINTER STORM WATCH FRONT RANGE FOOTHILLS AND PALMER DIVIDE
FRIDAY NIGHT INTO SATURDAY...

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

.DAY ONE...Today and Tonight

A few brief moderate to heavy snow showers will occur across the
northern and central mountains this afternoon. Otherwise, light
snow will occur across the higher mountains today into tonight. This
includes I-70 through Summit county, and Highway 40 over Berthoud
Pass and Rabbit Ears Pass. On the plains, rain showers will
become more numerous this afternoon and evening. Across far
eastern Colorado a few thunderstorms may also develop with gusty
winds up to 35 mph, lightning, and small hail possible.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

A storm system will drop toward the Four Corners region Friday
night as a strong cold front moves across northeast Colorado.
Snow will develop over the foothills by late afternoon. In the
Denver area snow will develop in the evening, with the eastern
plains receiving a mix of rain and snow changing to mostly snow
overnight. Significant snowfall will be possible in the foothills
and over the Palmer Divide south of Denver where a Winter Storm
Watch is in effect. Snow accumulations up to a foot will be
possible in the foothills. Snow accumulations in the Denver area
will be lighter, but snow accumulating on leafed out vegetation
may lead to some breaking tree branches.

The snow storm should be moving out of the state by Saturday
afternoon and evening, but cool and unsettled weather may last
through Tuesday with a chance of afternoon and evening showers
each day. Warmer and drier weather are expected to return
Wednesday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
