FIRE WEATHER PLANNING FORECAST FOR WRN MONTANA AND N CNTRL IDAHO  
NATIONAL WEATHER SERVICE MISSOULA MT  
502 AM MDT MON OCT 16 2017  
   
DISCUSSION
 
 
IDAHO: EXPECT MOSTLY SUNNY AND DRY CONDITIONS TO PERSIST THROUGH MUCH OF  
THE WEEK. WINDS WILL BE INCREASING EACH DAY, BECOMING QUITE GUSTY  
THROUGHOUT THE TERRAIN. SOME LIGHT RAIN MAY BRIEFLY BE POSSIBLE ACROSS  
THE NORTH FORK AND POWELL DISTRICTS. THOUGH ANY APPRECIABLE (WETTING  
RAINS) WILL HOLD OFF UNTIL FRIDAY WHEN A COLD FRONT SWEEPS ACROSS IDAHO  
BRINGING COLDER TEMPERATURES, VALLEY RAIN AND MOUNTAIN SNOW.  
 
MONTANA: WARM, DRY AND BREEZY CONDITIONS WILL BECOME WINDY OVER THE NEXT  
TWO DAYS ACROSS MUCH OF WESTERN MONTANA. THE STRONGEST WINDS WILL BE  
ACROSS THE HIGHER TERRAIN AND MOST ESPECIALLY NEARER TO THE CONTINENTAL  
DIVIDE WHERE GUSTS TO 60 MPH MAY BE POSSIBLE AT TIMES. A QUICK HITTING  
WEATHER SYSTEM WILL BRING SOME PRECIPITATION TO MAINLY THE KOOTENAI AND  
FLATHEAD NF LATE TUESDAY AND TUESDAY NIGHT. THE LIBBY, THREE RIVERS,  
CABINET AND REXFORD DISTRICTS COULD ACTUALLY SEE SOME DECENT RAIN FROM  
THIS BRIEF SYSTEM. CONDITIONS WILL DRY OUT AREA WIDE ON THURSDAY BEFORE  
A STRONG COLD FRONT BRINGS WINDY, COOLER CONDITIONS ALONG WITH VALLEY  
RAIN AND MOUNTAIN SNOW. EXPECT ACTIVE WEATHER TO PERSIST THROUGH THE  
WEEKEND AS WELL.
