A WARM AND SUNNY DAY IS IN-STORE FOR TODAY ACROSS  
WESTERN MONTANA AND CENTRAL IDAHO WITH A FEW ISOLATED  
THUNDERSTORMS POSSIBLE IN THE AFTERNOON AND EVENING. THE BEST  
CHANCE FOR THUNDERSTORMS WILL BE OVER SOUTHWEST MONTANA, SOUTHERN  
BITTEROOT MOUNTAINS, LEMHI COUNTY AND THE SOUTHERN CLEARWATER  
MOUNTAINS. THE STORMS WILL BE SLOW MOVING WITH THE MAIN THREATS  
BEING LIGHTNING AND GUSTY WINDS UP TO 40 MPH.  
 
A WEAK DISTURBANCE ON SUNDAY WILL BRING AN INCREASE IN WINDS  
SUNDAY AFTERNOON WITH SOME GUSTS IN THE 20 MPH RANGE POSSIBLE.  
ALSO A FEW ISOLATED THUNDERSTORMS WILL ONCE AGAIN BE POSSIBLE  
OVER PARTS OF SOUTHWEST MONTANA AND LEMHI COUNTY.  
 
STARTING MONDAY, A RIDGE OF HIGH PRESSURE WILL GRADUALLY BUILD  
OVER THE NORTHERN ROCKIES THROUGH THE REST OF THE WEEK.  
TEMPERATURES WILL LIKELY WARM EACH DAY WITH THE HOTTEST TEMPERATURES  
EXPECTED THURSDAY OR FRIDAY. TEMPERATURES ARE EXPECTED TO APPROACH  
THE CENTURY MARK FOR MANY VALLEYS BY THE END OF THE WEEK. ALSO,  
THE HOT AND DRY WEATHER WILL LIKELY BRING INCREASED ACTIVITY ON  
AREA WILD FIRES AND MAY AFFECT AIR QUALITY.  
 

 
   
AVIATION
 
GENERALLY SUNNY SKIES AND LIGHT WINDS WILL PREVAIL  
THROUGH THIS MORNING ACROSS WESTERN MONTANA AND CENTRAL IDAHO. BY  
MID AFTERNOON, A FEW THUNDERSTORMS ARE POSSIBLE, MAINLY DEVELOPING  
ACROSS SOUTHWEST MONTANA AND LEMHI COUNTY IN IDAHO. OTHER THAN  
LIGHTNING, THE MAIN THREAT WITH ANY STORMS THAT DEVELOP WILL BE  
GUSTY AND ERRATIC WINDS, WITH GUSTS UP TO 35 KTS POSSIBLE. KBTM
