NATIONAL WEATHER SERVICE MISSOULA MT  
345 AM MDT THU MAY 25 2017  
 
   
DISCUSSION
 
NORTHERLY FLOW WILL PERSIST OVER THE NORTHERN ROCKIES  
TODAY. TEMPERATURES WILL WARM SLIGHTLY TODAY, BUT STILL REMAIN AROUND 5  
DEGREES BELOW NORMAL. AFTERNOON/EVENING SHOWERS WILL REDEVELOP ONCE  
AGAIN THIS AFTERNOON AS THE ATMOSPHERE BECOMES UNSTABLE. A WEAK LOW  
PRESSURE SYSTEM WILL KEEP SHOWERS LINGERING ACROSS IDAHO COUNTY INTO  
SOUTHWEST MONTANA TONIGHT. TOMORROW WILL BE FAIRLY SIMILAR WITH  
TEMPERATURES NEAR SEASONAL AND AFTERNOON/EVENING CONVECTION. A RIDGE OF  
HIGH PRESSURE IS ANTICIPATED FOR THE WEEKEND ALLOWING FOR WARM AND DRY  
CONDITIONS. THE GENERAL CONSENSUS IS FOR WARM TEMPERATURES TO LINGER  
THROUGH MID NEXT WEEK, BUT SHOWERS AND THUNDERSTORMS COULD ONCE AGAIN  
DEVELOP DURING THE AFTERNOON HOURS OF MONDAY ONWARD.
