.DISCUSSION...In the wake of Monday`s cold front, a slightly cooler
but very dry airmass will spread across the fire area Tuesday.
General west-northwest winds will develop by early afternoon,
mainly along upper slopes and ridgelines, while lower slopes and
canyon bottoms likely remain sheltered and driven by slope flows.
The airmass will trend considerably drier Wednesday as a weak
weather system brushes by the area. This will result in an increase
in west-northwest winds Wednesday afternoon, again most notable
along upper slopes and ridgelines.
