...WINTER WEATHER ADVISORY FOR THE MOUNTAINS THROUGH MIDNIGHT
TONIGHT...

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

.DAY ONE...Today and Tonight

Accumulating snow will bring hazardous winter travel conditions
to the Colorado high country. Heavy snowfall occurring in the
western Colorado mountains this morning will shift to the north
central mountains including the I-70 corridor through Summit
county by early afternoon. Snowfall rates of 1 to 2 inches per
hour can be expected during the heaviest snowfall between 2 PM and
6 PM. The heavy snow combined with gusty winds and falling
temperatures will create hazardous travel conditions, with travel
delays quite possible this afternoon into early evening. Snow
intensity will decrease by mid evening, but light snow showers and
snow covered roads can be expected through tonight.

On the plains, rain showers will develop this afternoon, and
change over to snow as colder temperatures arrive by early
evening. Light snow accumulations of an inch or two along with
patchy blowing snow will be possible from the Palmer Divide to the
far eastern plains. little if any accumulation is expected along
the I-25 Corridor including Denver.

A storm system moving across the Central and Southern Rockies will
bring the stormy weather today.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Moist northwesterly flow aloft over Colorado will keep snow
showers going in the mountains through Friday. Additional
accumulations should be less than 4 inches. The plains will be dry
and cooler Thursday and Friday with gusty northwest winds in the
afternoons. Drier conditions are expected to return to the
mountains over the weekend while northeast Colorado also remains
dry. A passing upper level system on Monday may produce some
light snow in the mountains and on the plains.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight. Any
reports of snow accumulation will be appreciated.
