.DISCUSSION...
Elevated east to northeast winds continue today and Thursday along
the Sierra ridgetops. Valley inversions return today and look to last
into Saturday causing poor ventilation. An overall quiet pattern
continues during the remainder of the week going into next week aside
from a weekend cool down as a dry front moves through the region.
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
