...BLIZZARD WARNING OVER FAR NORTHEAST COLORADO TODAY AND
TONIGHT...
...HIGH WIND WARNING FOR MUCH OF THE REST OF NORTHEAST COLORADO...
...WINTER WEATHER ADVISORY IN THE MOUNTAINS THROUGH THIS
EVENING...

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

.DAY ONE...Today and Tonight

A potent Spring storm will develop over Colorado today which will
produce snowfall and very strong winds on the plains. Heavy snow
will fall over the far northeast plains of Colorado, where a
Blizzard Warning is in effect. The strong winds will combine with
falling snow to produce whiteout conditions and difficult if not
impossible travel there. Snow accumulations along and east of a
line from near Sterling to Akron should reach 5 to 10 inches.
Lighter accumulations can be expected west of that, tapering to
just a few light snow showers along the I-25 Corridor from Denver
north. The Palmer Divide may see a couple inches of snow late this
afternoon through this evening, with slick travel there.

Also, a High Wind Warning is in effect for much of northeast
Colorado today and tonight for northerly winds increasing to 35 to
50 MPH with gusts as high as 65 MPH. The strong winds may produce
local power outages. The windy and wintry conditions re expected
to last through tonight.

In addition, light to moderate snow over the mountains will
produce 2 to 4 inches of accumulation with locally higher amounts
today. Snow in the mountains will begin to decrease tonight.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Gusty winds will linger Saturday over much of the plains and
scattered snow showers will continue in the mountains. Drier,
warmer and less windy weather is forecast for Sunday through
Tuesday. An upper level disturbance will move into the mountains
Tuesday night with some snow over the Colorado High Country. The
Front Range foothills may also see gusty winds Tuesday night and
Wednesday morning. Another ridge will build over Colorado by
Thursday, with dry weather and seasonal temperatures.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
