Fire Weather Planning Forecast
National Weather Service Reno NV
439 AM PST Thu Dec 14 2017

.DISCUSSION...

High pressure will produce strong inversions with poor mixing and
ventilation conditions through Friday, with low humidity for
midslopes and ridges above the inversion layer. Inversions will ease
late Friday into the weekend as weak low pressure moves through the
Pacific Northwest, but then return by Monday 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
