.SHORT TERM...VALID FOR TDY AND FRI...

NICE UPSLOPE EVENT THIS MORNING ACROSS SOUTHERN ZONES. GOOD CALL
BY MIDNIGHT SHIFT TO GET A SNOW ADVISORY OUT...AS IT HAS ALREADY
VERIFIED IN ALL ZONES ISSUED WITH A GENERAL 2 TO 5 INCHES SO FAR.
SOME DRY AIR SLOWLY WORKING SOUTH...BUT LOOKS LIKE FRONTOGENESIS
WILL LINGER IN RED LODGE AREA THROUGH AT LEAST EARLY
AFTERNOON...SO HAVE INCREASED POPS FOR THE AFTERNOON THERE.
FURTHER EAST IN BIG HORNS...INSTABILITY INCREASES THROUGH THE DAY
AS MOISTURE DECREASES...BUT WITH MORNING REPORTS AROUND 2 INCHES
THERE...THINK THEY WILL BE UP TO 5 TO 8 BY MID AFTERNOON SO HAVE
ISSUED SNOW ADVISORY FOR BIG HORN ZONE FOR TODAY. SNOW AMOUNTS IN
FOOTHILLS WILL LIKELY PUSH 12 HOUR HEAVY SNOW CRITERIA SO HAVE
RAISED AMOUNTS TO JUST BELOW WARNING. WIND FORECAST IN EAST LOOKS
ON TRACK FOR 25 TO 40 MPH TYPE DAY AND HAVE MADE LITTLE CHANGES
THERE. RASCH

.LONG TERM...VALID FOR SAT...SUN...MON...TUE...WED...

EXTENDED MODELS WERE SIMILAR IN DEPICTING HIGH AMPLITUDE UPPER
RIDGE OVER THE WESTERN U.S. FOR THE WEEKEND. THE FORECAST AREA WAS
ON THE DOWNSTREAM SIDE OF THE RIDGE UNDER A DRY WARM NORTHERLY
FLOW. BY EARLY NEXT WEEK...COLD LOW PRESSURE WAS FORECAST TO MOVE
OVER THE HUDSON BAY. MODELS THEN DIFFERED IN HANDLING OF SHORTWAVE
ENERGY FORECAST TO MOVE AROUND THE LOW INTO THE NW U.S. CREATING
UNCERTAINTY IN THE FORECAST FOR MOST OF THE WEEK.

850 TEMPS IN LEE TROUGH PATTERN SUPPORTED RAISING TEMPS FOR SAT
SO HAVE BUMPED MAXES UP A FEW DEGREES. FUTURE SHIFTS MAY NEED TO
CONTINUE THE WARMING TREND. THE OTHER CHANGE WAS TO ADD POPS TO
MUCH OF AREA FOR TUE TO REFLECT GENERAL TROUGHINESS ACROSS THE
REGION AND COLD FRONT IN THE VICINITY. OTHERWISE WILL WAIT TO SEE
HOW MODELS TREND WITH HUDSON LOW BEFORE MAKING MORE CHANGES.

.AVIATION...

A COLD AIR MASS HAS DROPPED SOUTHWARD ACROSS THE REGION THIS
MORNING. UPSLOPE FLOW AND LOW LEVEL MOISTURE WILL PREVAIL OVER
THE SOUTHERN SECTIONS THROUGH MOST OF THE DAY CREATING IFR TO
MVFR CONDITIONS...WHILE THE REST OF THE AREA SEES FLURRIES AND
MAINLY VFR TO LOCAL MVFR CONDITIONS. TONIGHT...EXPECT IFR
CONDITIONS OVER THE FAR EAST WITH MVFR CONDITIONS FROM KBIL WEST
AS AN UNSTABLE NORTH FLOW CONTINUES OVER SOUTHERN MONTANA. TESAR
