This hazardous weather outlook is for northeast and north central

.DAY ONE...Today and Tonight

A strong weather system will move across the central and southern
Rockies through Saturday. Snow showers will become widespread in
the mountains this morning. Some of the showers will be heavy this
afternoon and evening, and a few thunderstorms are also possible.
Accumulations of 6 to 12 inches will be common over the higher
mountains and on the higher east slopes of the Front Range by noon
Saturday, with 2 to 6 inches in the mountain valleys and the
lower foothills.

On the plains, scattered rain showers will develop near the
eastern border this morning. Rain will then develop all across the
plains in the late afternoon. The rain is expected to change to
snow above about 5000 feet during the night. Some locations may
have an inch or two of snow on grassy areas, especially in the
higher elevations south of Denver.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Snow will continue in the mountains and foothills, with scattered
to numerous rain and snow showers across the northeast plains in
the morning, with rain showers in the afternoon. The storm system
will exit the region by Saturday evening, followed by a warmer and
relatively drier pattern for Sunday and Monday. The next chance
of precipitation for the region will be on Monday night and
Tuesday. It will be warmer by the middle of next week with a
slight chance of afternoon and early evening showers.


Snowfall reports from spotters will be appreciated.
