DISCUSSION
 
 
FORECAST CHALLENGES WILL FOCUS ON THE COLD FRONT AND ITS  
ASSOCIATED PRECIPITATION BEGINNING THIS EVENING. OTHERWISE, THE  
FORECAST IS PRETTY QUIET.  
 
THE COLDER CANADIAN AIR MASS IS EXPECTED TO PUSH FURTHER SOUTHWARD  
AFTER TODAY WITH A FEW SMALL RE-ENFORCING SHORT-WAVE LOBES TONIGHT  
THROUGH SUNDAY MORNING. BREEZY/GUSTY WEST WINDS TODAY WILL TURN  
NOTICEABLY FROM THE NORTH BEGINNING THIS EVENING, WHICH WILL  
SIGNAL THE START OF THE COLD FRONT. PRECIP MODEL BLENDS HINT AT  
SOME ASSOCIATED SCATTERED OR ISOLATED RAIN SHOWERS LATE THIS  
AFTERNOON, CHANGING TO SNOW SHOWERS LATER THIS EVENING AND  
LINGERING INTO SATURDAY MORNING. I EXPECT THAT MOST AMOUNTS WILL  
BE TRACE, BUT IF ANY SNOW HAPPENS TO ACCUMULATE, IT WILL BE AROUND  
HALF AN INCH OR LESS. LOW TEMPERATURES TONIGHT WILL DROP DOWN TO  
NEAR ZERO DEGREES ALONG THE INTERNATIONAL BORDER. HIGHS ON  
SATURDAY WILL STRUGGLE TO REACH THE MID 20S FOR MANY LOCATIONS.  
 
SATURDAY NIGHT INTO SUNDAY MORNING THE PRECIPITATION DIMINISHES AS  
IT CONTINUES TO MOVE SOUTH AWAY FROM NE MONTANA.  
 
MONDAY, A BROAD RIDGE OF HIGH PRESSURE WILL ALLOW TEMPERATURES TO  
REBOUND TO WELL ABOVE NORMAL.  
 
AFTER A DRY SHORT-WAVE TROUGH MOVES THROUGH THE REGION, BRINGING A  
BIT COOLER TEMPERATURES ON WEDNESDAY, THE REMAINDER OF THE WEEK  
WILL BRING AN AMPLIFIED RIDGE OF STRONG HIGH PRESSURE, AND HIGH  
TEMPERATURES WELL INTO THE MID 50S FOR MOST LOCATIONS.  
 

 
   
AVIATION
 
 
PATTERN: GENERAL PATTERN FLOW REMAINS FROM THE NORTHWEST. A COLD  
FRONT WILL BE THE FOCUS FOR SOME SCATTERED RAIN AND SNOW SHOWERS  
BEGINNING THIS EVENING.  
 
FLIGHT CONDITIONS: MAINLY VFR, WITH BRIEF MVFR INTERRUPTIONS IF AN  
ISOLATED SNOW SHOWER HAPPENS TO PASS DIRECTLY OVER A TAF SITE  
TONIGHT AND INTO SATURDAY MORNING. EXPECT MOST TO BE VICINITY  
SNOW SHOWERS.  
 
WINDS: FROM THE WEST TODAY AT 15 TO 20 KTS. THEN, FROM THE NORTH  
TONIGHT AT 15 KTS. TURNING BACK FROM THE NORTHWEST AT 10 TO 15 KTS  
THROUGH THE DAY ON SATURDAY.
