.DISCUSSION...

Inversions will ease this weekend as weak low pressure moves through
the Pacific Northwest, but then return by Monday as high pressure
rebuilds off the California coast. A colder storm will drop into the
region mid week for a brief chance of showers.

Note:  Thunderstorms imply gusty and erratic winds.
Note:  Mixing Heights are in feet above ground level of the valley floors.
