RED FLAG WARNING IN EFFECT UNTIL 5PM THIS EVENING FOR THE LOWER
FOOTHILLS, I-25 CORRIDOR, AND ADJACENT PLAINS
This hazardous weather outlook is for northeast and north central
Colorado.
.DAY ONE...Today and Tonight
Strong winds and critical fire weather conditions have developed
this morning across the urban corridor. Conditions favorable for
rapid fire spread will continue through the afternoon for areas in
the lower foothills of the Front Range Mountains, I-25 corridor,
and adjacent plains, where a Red Flag Warning is currently in
place through 5 PM tonight. Could continue to see some gusts
around 60-70 mph for our typical windy spots along the foothills
and our higher elevations where a High Wind Warning is set to
expire at 11 AM, but the general areas where the Red Flag Warning
is in place will see gusts to 45 mph and relative humidity values
drop down to around 15%.
.DAYS TWO THROUGH SEVEN...Friday through Wednesday
Strong winds can be expected along the highest elevations again
on Friday, though there will be significant improvements over what
the past few days have seen. An extended period of warm and dry
conditions are expected through the long term period, with only
light precipitation chances returning to the northern mountains
around the middle of next week. With well above normal
temperatures expected, there may be some periods of elevated fire
weather conditions that develop, and ensembles are leaning towards
another wind event possible by midweek.
.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed today or tonight.
