eastern Colorado. By afternoon, wind gusts of 30 to 40 mph will
be common, with a few gusts as high as 50 mph possible. The winds
will combine with humidities of 10-20% in areas near the mountains
to produce very high to extreme fire danger. The winds will be a
lighter in areas west of I-25 until late in the afternoon, so
those areas will have their highest fire danger around sunset.
Closer to the eastern border it will be windy but humidities will
be higher. Cooler temperatures will bring higher humidities this
evening, but strong winds will continue overnight and could
produce dangerous fire behavior on any fires that are burning.
