...FIRE WEATHER WATCH IN EFFECT FROM THURSDAY AFTERNOON THROUGH  
THURSDAY EVENING FOR STRONG WINDS AND LOW HUMIDITY FOR FIRE  
ZONES 673, 677, 684...  
   
DISCUSSION
 
 
WINDS WILL PICK UP IN THE LEE OF THE CASCADES AND OKANOGAN VALLEY  
THIS AFTERNOON AND EVENING WITH GUSTS UP TO 25 MPH. THERE IS A  
THREAT OF ELEVATED NOCTURNAL THUNDERSTORMS OVERNIGHT MOVING UP  
CENTRAL AND EASTERN WA. IF THESE STORMS DEVELOP THEY WILL LIKELY  
HAVE LIGHTNING, GUSTY WINDS AND LITTLE TO NO PRECIPITATION. A  
STRONG COLD MOVES OVER THE CASCADES THURSDAY. THE MAIN CONCERN  
WITH THIS FRONT WILL BE STRONG WINDS, ESPECIALLY IN THE LEE OF THE  
CASCADES AND COLUMBIA BASIN. THE FRONT WILL ALSO BRING A THREAT  
FOR SHOWERS AND SMALL CHANCE FOR THUNDERSTORMS MAINLY FOR THE  
EASTERN DISTRICTS AND NORTH IDAHO. CONFIDENCE IS LOW REGARDING  
AMOUNT OF LIGHTNING STRIKES BUT ANTICIPATING ISOLATED COVERAGE AT  
BEST. COOLER THAN NORMAL TEMPERATURES ON FRIDAY REBOUND BACK TO  
NORMAL OVER THE WEEKEND WITH BREEZY, DRY CONDITIONS.
