...RED FLAG WARNING REMAINS IN EFFECT UNTIL 8 PM MDT THIS EVENING
FOR WIND AND LOW RELATIVE HUMIDITY FOR ALL OF THE NORTHERN
MOUNTAINS AND HIGH VALLEYS...FIRE WEATHER ZONES 211 THROUGH 214,
217, AND 218...
...RED FLAG WARNING IN EFFECT FROM NOON TO 8 PM MDT WEDNESDAY FOR
WIND AND LOW RELATIVE HUMIDITY FOR THE NORTHERN TIER OF COLORADO
MOUNTAINS AND HIGH VALLEYS...FIRE WEATHER ZONES 211, 213, 217, AND
218...
.DISCUSSION...Tonight and Wednesday...
Humidity readings this afternoon have plunged into the single
digits with winds gusting to 20-35 mph over the higher terrain.
Those critical Red Flag conditions will persist into the early
evening, but winds slacken off by 7-8 pm so critical conditions
are expected to cease by then. Humidity recovery tonight will be
poor in all but valley locations where only moderate recovery
occurs.
Wednesday will feature a continuation of very warm/hot
temperatures with elevated to critical fire weather conditions.
There will only be a very slight bump in minimum humidity compared
to today`s ridiculously low values, so we`ll still see critical
levels of just 8-15% over the forecast area. Winds will slacken
just a bit, but with gusts around 25 mph where stronger flow still
resides over the northern tier of mountains and high valleys
we`ve issued a Red Flag Warning for those zones (211, 213, 217,
and 218).
LONG TERM DISCUSSION...Wednesday night through Sunday...
More critical fire weather conditions are expected Thursday and
Friday. There`s not much change for Thursday humidity-wise, but
unfortunately winds are expected to get an uptick in the high
country due to strengthening flow aloft. This occurs as yet
another shortwave moves across the Northern Rockies and tightens
the mid level pressure gradients. We`ll likely have extensions of
Red Flag Warnings for the mountains and high valleys, and possibly
down the foothills by Friday as winds strengthen even further.
Saturday trends a bit cooler, but we`ll still have some wind to
contend with. More significant relief should finally arrive by
Sunday as winds become light, temperatures cool to below normal
levels, and humidities rebound accordingly. The main chance of
measurable rainfall this weekend would be along and east of the
Front Range mountains.
