...RED FLAG WARNING FOR THE FOOTHILLS AND PLAINS TODAY FOR
CRITICAL TO EXTREME FIRE DANGER...
...HIGH WIND WATCHES AND WINTER STORM WATCHES AND ADVISORIES FOR
THE MOUNTAINS PORTIONS OF THE PLAINS FRIDAY AND SATURDAY...

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

.DAY ONE...Today and Tonight

A Red Flag Warning will be in effect again today for Park County,
the Front Range Foothills, and most of the plains of northeast
Colorado due to critical to extreme fire danger conditions. Near
record warmth, strong gusty winds, and low humidity can be
expected. The strongest winds and extreme fire danger will occur
from South Park and the Southern Front Range Foothills eastward
across the Palmer Divide area, and extend as far northeast as
Denver and Limon this afternoon. Peak gusts will reach 40 to 50
mph in those locations. Farther north, the strong, gusty winds
should hold off until late this afternoon and evening ahead of and
just behind a strong cold front.

This front will bring a return of snow and hazardous winter travel
conditions to the mountains by this evening. On the plains, a few
rain showers will develop with potential for a thunderstorm over
the northeast corner of the state. Temperatures will turn cold
enough to support light snow showers later tonight, but any
potential accumulation should hold off until Friday. Gusty
northwest winds will persist through the night.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

A strong Spring storm system will move across the state through Friday,
bringing snow to the mountains, and strong north winds to the
plains along with some light snow. Moderate snow accumulations of
4 to 10 inches are expected in the mountains. A Winter Weather
Advisory is in effect for tonight and Friday.

A bigger issue for the eastern plains Friday will be the strong
northerly winds of 40 to 60 mph. Snow accumulations will generally
be less than an inch, except for the northeast corner of the
state where 3 to 6 inches of snow is possible. The strong winds
and falling snow will produce areas of blowing snow and whiteout
conditions at times, especially over the far northeast. A High
Wind Watch is in effect for most of the plains Friday and Friday
night, while a Winter Storm Watch has been issued for the
northeast corner of the state where blizzard conditions may
develop. Windy conditions will linger through Saturday over much
of the plains while snow decreases in the mountains and across the
plains.

Drier, warmer and less windy weather is forecast for Sunday
through Tuesday. Mountain areas may see a little more snow Tuesday
night.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
