Fire Weather Planning Forecast
National Weather Service Reno NV
552 AM PDT Sun Aug 20 2017

.DISCUSSION...

Thunderstorms remain a possibility each day through midweek with
increasing coverage Monday through Wednesday. Storms will get
progressively wetter, lessening the risk of new fire starts, but also
increasing the flash flood risk. Drier conditions with more typical
westerly afternoon breezes are expected Thursday and Friday with
lighter winds and warming temperatures next weekend as a ridge builds
into the west.


Note:  Thunderstorms imply gusty and erratic winds.
Note:  Please see operating plan for detailed zone descriptions
