DISCUSSION
 
 
AN ACTIVE PATTERN WILL CONTINUE TODAY WITH PLENTY OF MOISTURE FOR  
THUNDERSTORMS, SOME WITH HEAVY RAIN AND GUSTY WINDS. LIGHTNING FIRE  
STARTS ALSO REMAIN A RISK DUE TO FAST STORM MOTION, ESPECIALLY FOR  
NORTHWEST NEVADA. A DRIER AND MORE STABLE AIR MASS WILL BRING A  
DECREASE IN STORM POTENTIAL FOR THE REMAINDER OF THE WEEK. SEASONAL  
TEMPERATURES AND TYPICAL AFTERNOON BREEZES WILL ALSO RETURN.  
 
NOTE: THUNDERSTORMS IMPLY GUSTY AND ERRATIC WINDS.  
NOTE: MIXING HEIGHTS ARE IN FEET ABOVE GROUND LEVEL OF THE VALLEY FLOORS.
