...Potential for Blizzard conditions on the Palmer Divide and
portions of the Northeast plains for later tonight and Friday
morning.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL

.DAY ONE...TODAY AND TONIGHT

Strong southwesterly winds combined with low humidity will bring
critical fire weather conditions along the southern foothills and
northeast plains this afternoon.  Rain and snow showers will
develop in the mountains late this afternoon.

There is the potential for an isolated severe thunderstorm over
the far northeast plains, mainly over Phillips and Sedgwick
counties later this afternoon and evening. Damaging winds and
hail would be the main impacts.

For tonight, a storm system is expected to track slowly across
Colorado. This system will bring much needed precipitation to the
region. Moderate to heavy snow will be possible in the mountains
foothills along and south of the Interstate 70 Corridor and
over the Palmer Divide above 5500 feet, with widespread rain or a
mix of rain and snow over the northeast plains. The combination
of strong winds and snow could produce blizzard conditions late
tonight I-25 south of Denver toward Monument and I-70 east of
Denver to just west of Limon.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

On Friday a storm system will move slowly east of Colorado. This
system will bring snow to the mountains, foothills and across
portions of the adjacent plains. In addition strong winds will
occur over the plains of northeast Colorado which may create
blizzard conditions over the Palmer Divide eastward towards the
Limon area.

Additional accumulations will range from 4 to 8 inches in the
mountains and foothills with up to 6 inches over the Palmer
Divide. Across the adjacent plains 2 to 4 inches may fall around
the Denver area with up to 6 inches near Limon. Elsewhere snow
amounts will be under 2 inches. North winds of 25 to 40 mph with
gusts up to 55 mph will occur over the plains with gusts up to 65
mph over the Palmer Divide towards limon.

The snow and wind should gradually diminish through the afternoon
hours from west to east.

Dry and warmer weather will return on Saturday. The next weather system
could bring another chance of precipitation to the region on
Sunday, then drier again Sunday night into Monday.
