.DISCUSSION...
High pressure continues this week, resulting in light winds,
dry conditions, a warming trend through Thursday, valley
inversions, and poor mixing/ventilation. Said conditions will continue
through Friday. Latest model runs hint at Friday being drier than
previously forecasted, with a system arriving as early
as Saturday, which will bring light rain and snow showers (15-20%
chance for wetting rains), 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
