.DISCUSSION...Winds resulting from today's frontal passage will
stick around until about 2100 PDT tonight. Gusts at all elevations
of the fire will stay around 20 mph from the southwest or west.
Ridgetop gusts may run to about 25-30 mph. The well-mixed
atmosphere should allow for good RH recovery tonight. 

A ridge of high pressure will bring a warming and 
drying trend Monday. Thermal belts begin to strengthen Monday 
night, with limited RH recoveries. Expect light, terrain-driven 
winds Monday into Tuesday. Thunderstorm activity will not be out
of the question on Tuesday, though most activity looks to be east
of the fire, so including only low probability for thunder for 
now. Outflow winds and lightning will be the primary threats 
should a storm approach the fire.
