...ELEVATED FIRE WEATHER FOR SOUTH PARK TODAY...

...EXTREME FIRE WEATHER AND VERY WINDY FRIDAY FOR THE LOWER
ELEVATIONS AND THE EAST SLOPES OF THE FRONT RANGE...

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

.DAY ONE...Today and Tonight

Warm and dry weather is expected this afternoon with critical
fire weather conditions in Park County where a Red Flag Warning is
in effect from noon to 8 PM MDT. Elevated fire weather conditions
are expected over the plains and foothills this afternoon and
early evening. Temperatures will be well above seasonal normals
over the plains and foothills today.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Extreme fire weather conditions are expected on Friday, with the
most dangerous conditions existing from the foothills of
Jefferson, Park, and Douglas counties east and northeast across
the plains. Very warm, dry, and windy weather would create
dangerous conditions, making any new wildfire difficult if not
impossible to control. If you live in a vulnerable area, it would
be prudent to have a go bag ready with important documents,
medications, and valuables in the event of an evacuation.

The strong winds on Friday will also create blowing dust and
hazardous travel conditions. I-70 and I-76 east and northeast of
Denver, as well as many other highways across eastern Colorado,
could have severely impacted travel and possible road closures due
to poor visibility.

There is a slight chance of thunderstorms east of Sterling and
Akron Friday evening. If there are storms, a severe storm with
damaging winds and large hail would be possible. There is a slight
chance of light showers across the rest of the plains.

Mountain areas will see rain and snow showers develop late Friday
afternoon, continuing through Saturday. A few inches of snow can
be expected, with slick travel conditions possible over some of
the mountain passes.

Dry and warmer weather is expected to redevelop for much of next
week.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
