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

.DAY ONE...Today and Tonight

Another very warm and dry afternoon today. Highs will be near 80
across the northeast plains, with mid 50s and 60s in the
mountains. Winds will gradually increase over the plains this
afternoon with gusts up to 25 mph at times. Tonight, snow showers
will develop in the mountains with accumulations of up to 3
inches along west and northwest facing slopes. Gusty west to
northwest winds will accompany a cold front that will spread
across the northeast plains after midnight.

A dry southwesterly flow aloft will be over the region today,
ahead of a fast moving Pacific trough that will move into
Colorado tonight.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Any mountain snow will end early Saturday morning. Little to no
additional snowfall is expected after sunrise Saturday. It will
be windy behind a cold front Saturday. The strongest winds will be
found across the eastern plains and along the Wyoming border
where 40 to 50 mph gusts will be possible. The windy conditions
will continue Saturday night and early Sunday morning in and near
the foothills with gusts to 50 mph. Next chance rain and snow will
come Thursday as a weak system quickly moves across the state.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
