Fire Weather Planning Forecast

545 AM PST Tue Dec 12 2017

.DISCUSSION...

High pressure will produce strong inversions with poor mixing and
ventilation conditions through Thursday, with low humidity for
midslopes and ridges above the inversion layer. Inversions may ease
by Friday as weak low pressure moves through the Pacific Northwest,
but then return for the weekend as high pressure rebuilds off the
California coast.


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
