AREA FORECAST DISCUSSION  
NATIONAL WEATHER SERVICE GLASGOW MT  
251 PM MDT FRI MAR 24 2017  
   
SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH SUN
 
 
WITH THE EXCEPTION OF ONE WEAK WAVE OF LOW PRESSURE SATURDAY  
AFTERNOON THROUGH SATURDAY NIGHT, THE SHORT TERM FORECAST PERIOD  
LOOKS TO BE RATHER UN-EVENTFUL.  
 
SHERIDAN COUNTY IN OUR NE CWA CORNER HAS LEFT-OVER STANDING WATER  
IN THE MID MUDDY CREEK FLOODPLAIN AND MAY LEAD TO SOME PATCHY  
OVERNIGHT AND MORNING FOG, BUT IT IS NOT EXPECTED TO BE AS THICK  
OR AS WIDESPREAD AS IT WAS THIS MORNING. NEXT SHIFT SHOULD KEEP AN  
EYE ON THIS, JUST IN CASE.  
 
THIS NEXT WEATHER DISTURBANCE WILL RIDE ALONG A PACIFIC NW  
TROUGH, BUT WILL NOT HAVE NEAR ENOUGH MOISTURE TO MAKE ENOUGH OF  
AN IMPACT FOR MOST OF OUR CWA. MODELS ARE LINING UP A BAND OF RAIN  
SHOWERS WITH THIS SYSTEM MOVING THROUGH OUR SE ZONES. BEST  
CHANCES FOR ACCUMULATING RAIN SHOWERS WOULD BE NEAR AND SOUTH OF  
THE BIG SHEEP MOUNTAINS.  
 
EXPECT WARM DAYS AND COOL TO COLD NIGHTS.

LONG TERM...SUN NIGHT THROUGH FRI
 
 
AFTERNOON UPDATE:  
UPDATES FOR THE AFTERNOON WERE MINIMAL. FORECAST BUILDER WAS RUN  
TO CYCLE IN THE LATEST DATA; HOWEVER, VERY FEW CHANGES WERE MADE  
ON TOP OF THIS. POP GRIDS ON TUESDAY/TUESDAY NIGHT AND  
THURSDAY/THURSDAY NIGHT WERE INCREASED BEYOND BUILDER'S OUTPUT  
TO BETTER MATCH UP WITH NEIGHBORS. NO OTHER SIGNIFICANT CHANGES  
WERE OBSERVED.  
 
GAH  
 
PREVIOUS LONG TERM DISCUSSION:  
PROGRESSIVE PATTERN FOR NEXT WEEK WITH A SERIES OF SHORTWAVE TROFS  
MOVING THROUGH THE REGIONS. STRONGEST ENERGY WITH THESE SYSTEMS  
EXPECTED TO PUSH THROUGH THE DESERT SOUTHWEST BUT WITH ENOUGH  
CONNECTION TO THE NORTH PORTION OF THE TROF TO BRING SOME  
POTENTIAL FOR SHOWERS INTO EASTERN MONTANA.  
 
MONDAY IS EXPECTED TO BE DRY AND WARM WITH TROF DIGGING INTO THE  
GREAT BASIN. THIS SYSTEM MOVES ACROSS THE ROCKIES ON TUESDAY FOR  
SLIGHT COOLING OF TEMPERATURES AND SOME SHOWERS POSSIBLE.  
 
PATTERN REPEATS WITH DRY WEATHER ON WEDNESDAY FOLLOWED BY TROF AND  
SHOWERS ON THURSDAY. MODELS INTENSIFY THE SOUTHERN PORTION OF THE  
TROF AS IT CLOSES OFF OVER THE SW STATES. THIS WILL KEEP THE  
COOLER AND POTENTIALLY WET WEATHER OVER EASTERN MONTANA INTO  
FRIDAY.

AVIATION
 
 
VFR CONDITIONS WILL PREVAIL FOR ALL TAF SITES THROUGHOUT THE TAF  
CYCLE. SOME OVERNIGHT FOG MAY DEVELOP AGAIN TONIGHT BUT IT IS  
EXPECTED TO BE EAST OF THE N DAKOTA / MONTANA STATE LINE.  
 
WINDS FROM THE SOUTH 10-15 KTS WILL TURN MORE FROM THE SOUTHEAST  
LATER TONIGHT, DIMINISHING ONLY SLIGHTLY
