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

.DAY ONE...Today and Tonight

Showers and thunderstorms will become more numerous behind the
passage of a cold front. Winds will increase behind the front,
with gusts around 40 mph expected. A few thunderstorms will be
capable of producing small hail, brief heavy rain, and stronger
wind gusts around 50 mph.

Snow levels will start out between 9 and 10 thousand feet this
afternoon, and then lower to around 7000 feet this evening as
temperatures continue to drop. Heavier snow showers spreading
southward from the Wyoming border area 3-4 PM into the I-70
corridor through the mountains by 5-6 PM will be capable of
producing slush or snow covered roads, and slick/slow travel
through this evening. Accumulations may range from 1 to 5 inches
in the higher foothills and mountains before snow tapers off
between 9 PM and midnight.

Gradual drying and clearing can then be expected overnight.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

There will be a chance of a few showers and thunderstorms
lingering on Tuesday. It will still be cool, with light snow
accumulations over the mountains. Drier and warmer weather will
return for Wednesday. Thunderstorm chances are expected to
increase again over the plains Thursday through Sunday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight. However,
any reports of strong gusty winds or mountain snowfall this
afternoon and evening would be appreciated.
