.DISCUSSION...
High pressure will continue to build this week, resulting in
light winds, dry conditions, cool mornings, valley inversions,
and poor mixing/ventilation. These conditions will continue
through Thanksgiving, with a winter storm system arriving as early
as Friday, bringing the next chance of precipitation, a slight
cool-down, and increasing winds.
Note: Thunderstorms imply gusty and erratic winds.
Note: Mixing Heights are in feet above ground level of the valley floors.
Note: Please see operating plan for detailed zone descriptions
