.DISCUSSION...
Light west breezes with valley inversions will lead to poor to fair
ventilation this afternoon. A brush-by system may increase ridgetop
gusts to around 40 mph tonight. High pressure will build next week
resulting in light winds, dry conditions, and poor mixing/ventilation
until a system provides the next chance of precipitation and
increasing winds by next weekend.
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
