.DISCUSSION...
Strong winds will accompany a cold front later today across the
region. Areas west of the Laramie Range will not have fire weather
concerns. Afternoon humidity minimums near 20 percent will be
possible east of the Laramie Range because of warmer temperatures
and strong, gusty winds. This will cause a few FWZs near the CO/WY
state border to have elevated concerns until the cold front passes
this afternoon to the south.
