FIRE WEATHER PLANNING FORECAST FOR MONTANA  
NATIONAL WEATHER SERVICE GREAT FALLS MT  
432 AM MDT SUN MAY 20 2018  
   
DISCUSSION
 
 
A SOUTHERLY FLOW ALOFT WILL BRING MUCH WARMER TEMPERATURES TO THE  
AREA TODAY. AN INCREASE IN MOISTURE AND WEAK WEATHER DISTURBANCE  
MOVING UP FROM THE GREAT BASIN COULD BRING WIDELY SCATTERED  
SHOWERS AND ISOLATED THUNDERSTORMS TO SOUTHERN FIRE DISTRICTS THIS  
AFTERNOON AND EVENING. ADDITIONAL MOISTURE AND WEATHER  
DISTURBANCES TRACKING OUT OF THE GREAT BASIN REGION WILL BRING A  
CHANCE FOR SHOWERS AND THUNDERSTORMS EACH DAY THROUGH THE UPCOMING  
WEEK WITH TEMPERATURES REMAINING NEAR OR ABOVE SEASONAL AVERAGES.
