WEAK MONSOON FLOW WILL BE REPLACED BY DRIER AIR THAT WILL ELIMINATE  
THE THUNDERSTORM THREAT FRIDAY THROUGH SUNDAY. A MINOR INFLUX OF  
MONSOONAL MOISTURE EARLY NEXT WEEK MAY TRIGGER A FEW AFTERNOON  
THUNDERSTORMS OVER THE MOUNTAINS MONDAY.  
 
   
..DISCUSSION FROM PHXFWFPSR
 
 
THUNDERSTORM CHANCES WILL CONTINUE FOR THE HIGHER ELEVATIONS  
THROUGH SATURDAY BUT COVERAGE WILL BE FAR LESS THAN THE PAST SEVERAL  
DAYS. REGARDLESS, ANY LOCATION EXPERIENCING STORMS MAY EXPECT HEAVY  
RAIN, STRONG WINDS, AND LOCALIZED FLOODING. MINIMUM HUMIDITY LEVEL  
WILL REMAIN AROUND A 20-40% RANGE WITH GOOD TO EXCELLENT OVERNIGHT  
RECOVERY. OUTFLOW WINDS WILL BE COMMON AROUND THUNDERSTORMS IN THE  
EVENINGS, BUT OTHERWISE LIGHT WINDS WILL PREVAIL.
