.DISCUSSION...Red Flag conditions are expected to continue 
through Friday. The most concerning day of the work week looks to
be today as winds amplify across a corridor from the Four Corners
to the northern Colorado mountains. Generally, winds will gust 
35-45 mph in this area, with locally stronger gusts as high as 50 
mph in southwest Colorado. Lighter winds move in for the weekend,
though single-digit RH values look to remain in place.
