...CRITICAL FIRE WEATHER CONDITIONS THROUGH EARLY THIS EVENING
OVER THE HIGH MOUNTAINS AND HIGH VALLEYS FROM BOULDER COUNTY AND
GRAND COUNTY SOUTH DOWN TO PARK COUNTY...

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

.DAY ONE...Today and Tonight

Warm, windy, and dry conditions will persist over the high
mountains and high valleys today, especially Grand, Summit, and
Park counties today, bringing critical fire weather conditions.
Higher humidity and a switch from west-southwest winds to north
winds will spread south later this afternoon into the evening over
these areas to decrease the fire danger.

A cold front across eastern Colorado today, which brought low
clouds and patchy drizzle, will be strengthened and will deepen
later this afternoon with another push of cold air. The moisture
will deepen enough for areas of light snow and freezing drizzle
along the east slopes of the Front Range mountains, foothills, and
near by plains late this afternoon through tonight.


.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Warm, breezy, and dry conditions will persist over the mountains
and mountain valleys Friday, and then it will get windier
Saturday, with gusts around 40 mph. Fire danger will remain
elevated, even with higher humidity readings Saturday.

Snow and much colder temperatures are expected to spread south
across the area Saturday night through Sunday, and remain into
Monday. Several inches of snow to locally a foot or more will be
possible in the mountains, with a few inches possible in lower
elevations. Get prepared for a sharp change in our weather. Winter
travel conditions can be expected as temperatures will be cold
enough to allow snow to accumulate on roads, creating slick travel
conditions.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today and tonight.

URGENT - FIRE WEATHER MESSAGE
National Weather Service Denver/Boulder CO
332 PM MDT Thu Oct 22 2020

...RED FLAG WARNING UNTIL 7 PM MDT THIS EVENING FOR WIND AND LOW
RELATIVE HUMIDITY FOR MIDDLE PARK, SOUTH PARK, AND THE HIGH
MOUNTAINS OF BOULDER, GILPIN, CLEAR CREEK, SUMMIT AND PARK
COUNTIES...FIRE WEATHER ZONES 212, 213 AND 214...
...FIRE WEATHER WATCH FRIDAY AFTERNOON THROUGH SATURDAY EVENING
FOR THE MOUNTAINS AND HIGH VALLEYS...FIRE WEATHER ZONES
211>214...217...AND 218...
...FIRE WEATHER WATCH LATE FRIDAY NIGHT THROUGH SATURDAY EVENING
FOR FIRE WEATHER ZONE 215...

.Very low dewpoints and strong west-southwest winds over the high
mountains and valleys will lead to critical fire weather
conditions today as humidities will be in the low to mid teens
and winds gusting 35 to upwards of 50 mph at elevations above
10,000 feet. Elevations above this cold front and on the lee
(west) slopes of the Front Range Mountains will be in much drier
air, with westerly winds gusting 25 to 40 mph.

Winds will decrease this evening and remain lighter Friday
morning. However, winds will begin to increase again later Friday
afternoon and especially Friday night and Saturday. Wind gusts
will likely increase to around 40 mph in valley and higher
foothills areas by Saturday, with gusts up to 60 mph or more over
the mountains. Despite humidity being higher Friday night into
Saturday, the existing fires burning in heavy fuels may lead to
considerable additional growth during the period of stronger
winds.
