...ELEVATED FIRE DANGER TODAY...WINTER RETURNS TOMORROW AND
TUESDAY...

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

.DAY ONE...Today and Tonight

Gusty winds in the mountains and foothills are expected to
gradually decrease by this evening. Meanwhile, unseasonably warm
temperatures, very low relative humidity and gusty southwest winds
of 25 to 35 mph today will create high rangeland fire danger
conditions along the Palmer Divide in Douglas, Elbert and Lincoln
Counties this afternoon. Winds will subside in most areas this
evening. After midnight, a cold front will slip into northeast
Colorado bringing much colder temperatures, low clouds and a
chance of freezing drizzle to the area towards morning.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Areas of light freezing drizzle and very light snow on the plains
may bring slick travel conditions to the plains and I-25 Corridor
Monday morning. Sidewalks may also be slick in areas that see the
freezing drizzle.

In the mountains, snow will develop through the course of the day
Monday and become heavier in the afternoon and evening. That snow
will spread northeast across the plains late Monday afternoon and
Monday night.

At this time, expect snow amounts with storm system to range
between 1 and 4 inches on the plains, with potential for up to 6
inches in locations north of Denver to the Wyoming border. In the
mountains, look for snowfall amounts to mostly range between 4 and
10 inches, with locally higher amounts north of Rabbit Ears Pass.

Temperatures will be very cold with single digit lows and some
below zero readings possible both Monday night and Tuesday night.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.

This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...This Afternoon and Tonight

Strong and locally damaging winds will continue this evening and
overnight across the Wet Mountains, Sangre De Cristo mountains and
the adjacent lower elevations. West to southwest winds could gust
up to 85 mph across the higher peaks and eastern slopes of these
mountains...with gusts to around 65 mph across the adjacent lower
elevations of the Wet Mountain Valley and Huerfano county.

Snow and wind will increase across the Continental Divide tonight
with the heaviest snow impacting the Eastern San Juan mountains
overnight.  Up to 5 inches of wind driven snow will be possible
across the eastern San Juans by morning with additional heavy snow
expected Monday and Monday night.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Snow, heavy at times, will continue in the mountains through
Tuesday morning. Winds gusting to around 60 mph will cause
widespread blowing and drifting snow and poor visibilities through
the mountain passes. The heaviest snow will fall over the eastern
San Juan Mountains where up to around 2 feet of snow is expected
by Tuesday morning. The La Garita, eastern Sawatch and Mosquito
Ranges farther north could see up to a foot of snow with locally
higher amounts possible particularly over the Sawatch range. The
higher terrain of the Sangre de Cristo Mountains and Pikes Peak
could see 4 to 8 inches of snow.

Across the valleys and plains, amounts will be much less. The San
Luis valley could see an inch or 2 of snow. The Upper Arkansas and
Wet Mountain Valleys could see maybe an inch of snow. The plains,
particularly over the Pikes Peak Region, could see some snow showers
move across Monday night into early Tuesday. However, any accumulations
should be pretty spotty and light, generally coming in well under
an inch.

Very strong winds will continue across the region on Monday.
Across the higher elevations and east facing slopes of the Sangre
De Cristo and Wet mountains, gusts to around 80 mph will be
possible. Along the southern I-25 corridor gusts up to 65 mph will
be possible through late morning.

Another weather system could impact the region late in the week,
bringing another chance of snow to the area. However, details of
the storm are very uncertain at this time due to a high level of
variability in models.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be likely tonight across the mountains and southern I-25 corridor.
