...RED FLAG WARNING SOUTHERN FRONT RANGE FOOTHILLS AND PLAINS
MAINLY ALONG AND SOUTH OF THE INTERSTATE 70 CORRIDOR...

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

.DAY ONE...Today and Tonight

Dry air and strong south-southwesterly winds will bring critical
fire weather conditions to the southern foothills as well as the
Palmer Divide and areas over the plains along and south of I-70
this afternoon into early evening. Humidity will be in the 10 to
15 percent range and winds gusting 25 to 40 mph.

A few storms will likely form over the northern mountains and
northern plains later this afternoon. Main hazards will be gusty
outflow winds and lightning. There will be a slight chance of
stronger showers and thunderstorms over far northeast Colorado,
mainly over Sedgwick and Phillips counties. If they do form, they
could be strong to severe with large hail and strong wind, though
best chance will be east of the forecast area.

Elsewhere, fire weather concerns will be increasing due dry and
gusty winds.


.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Other than a few showers and storms on the plains late Saturday
afternoon and evening, drier weather will return for the weekend.
Fire danger will still be elevated over the high mountain valleys
on Saturday due to breezy conditions and low humidity.

Dry weather will remain in place through the middle part of next
week.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
