.SHORT TERM...VALID FOR MON AND TUE...

AVN AND ETA ARE NOT IN GOOD AGREEMENT FOR THE SHORT TERM. WHEN
COMPARING HEIGHT AND RH FIELDS WITH VAPOR VAPOR IMAGERY...THE AVN
SEEMS TO HAVE A BETTER HANDLE ON THINGS. HOWEVER...THE ETA IS HANDLING
CONVECTION BETTER ACROSS THE NORTHERN PART OF THE STATE. THEREFORE...
WILL USE A BLEND OF THE TWO. ALTHOUGH HAVE DECIDED TO GO MORE WITH THE
AVN AS IT CONTINUES TO BRING TROUGHINESS INTO THE AREA. LONG WAVE
PATTERN WOULD AGREE WITH THIS AS WEAKNESSES WITHIN THE FLOW WOULD
CONTINUE TO BRING DISTURBANCES INTO THE PAC NW COAST AND DROPPING THEM
INTO IDAHO.

TONIGHT & MONDAY...SOME CU HAS BEEN BUILDING ACROSS THE EAST AS THE
UPPER LEVEL LOW CONTINUES TO CIRCULATE JUST TO THE NORTH OF OUR FORECAST
AREA. WILL PUT IN A SLIGHT CHANCE OF A THUNDERSTORM FOR THIS EVENING FOR
THOSE AREAS. IN ADDITION...A TROUGH WILL STRETCH FROM NORTH DAKOTA TO
THE PAC NW COAST. MOST OF THE DYNAMICS WILL REMAIN TO OUR NORTH AS MID
LEVEL DRYING BEGINS TO MOVE OVER THE AREA. BY MONDAY...A NEW TROUGH
FORMS OVER IDAHO AND BEGINS TO DIG SOUTH. LATE IN THE DAY MONDAY...A
PIECE OF ENERGY GETS KICKED OUT AND BEGINS TO AFFECT OUR WESTERN ZONES
BY LATE EVENING. SO WILL INTRODUCE POPS FOR THE WEST FOR MONDAY
EVENING.

TUE & TUE NIGHT...TROUGH AND LOW CLOSES OFF AND BEGINS TO RETROGRADE
SLIGHTLY...SENDING A STRONG PIECE OF ENERGY ACROSS YELLOWSTONE PARK AND
OUR WESTERN ZONES WHERE QPF AMOUNTS WILL BE AROUND 0.75. THIS IS MOST
LIKELY A CONVECTIVE FEEDBACK SIGNATURE WITH THE MODEL BUT IT STILL
LOOKS TO BE A GOOD CHANCE FOR SOME DECENT PRECIP.  HOOLEY

.LONG TERM...VALID FOR WED...THU...FRI...SAT...SUN...

ANOTHER CUTOFF SYSTEM EXPECTED TO AFFECT MONTANA BY THE MIDDLE OF NEXT
WEEK. TIMING AND POSITIONING OF SHORTWAVES THIS FAR OUT IS SUSPECT BUT
IT LOOKS LIKE THE SYSTEM REGRESSES A BIT TO THE WEST ON WEDNESDAY SO
WILL ADJUST POPS DOWN IN THE EAST FOR THIS TIME PERIOD. THE SYSTEM
THEN PULLS SLOWLY TO THE NORTHEAST WEDNESDAY NIGHT AND THURSDAY...HAVE
POPS IN FOR THE NORTH AND NORTHEAST ZONES AS THIS SYSTEM MOVES INTO
NORTH DAKOTA. SHORTWAVE RIDGE BUILD IN BEHIND SYSTEM ON FRIDAY FOR A
PARTLY CLOUDY DAY. NEXT WAVE MOVES INTO WESTERN MONTANA SATURDAY
BRINGING ANOTHER CHANCE OF SHOWERS AND THUNDERSTORMS OVERNIGHT SATURDAY
INTO SUNDAY. TEMPERATURES STAY GENERALLY AROUND SEASONAL NORMS...WITH NO
LARGE SCALE PATTERN SHIFTS NOTED CLOUD COVER AND PRECIPITATION WILL BE
THE BIGGEST FACTOR IN DETERMINING HIGH AND LOW TEMPERATURES. CHAMBERS
