DISCUSSION
 
 
DEEP WESTERLY FLOW WILL BRING STRONGER DOWNSLOPE WINDS ACROSS  
NORTHERN MONTANA TODAY. THE COMBINATION OF BREEZY CONDITIONS AND  
RELATIVE HUMIDITY LEVELS BELOW 30 PERCENT MAY ELEVATE FIRE  
WEATHER CONDITIONS FOR A TIME ACROSS PORTIONS OF THE REGION,  
THOUGH MARGINAL FUELS DUE TO RECENT WET WEATHER WILL BE A LIMITING  
FACTOR. ISOLATED SHOWERS AND COOLER WEATHER ARE EXPECTED FOR THE  
WEEKEND, BUT NEXT WEEK WILL FEATURE HOT AND DRY WEATHER AS AN  
UPPER RIDGE BUILDS IN ACROSS THE WEST.
