.DISCUSSION...

TODAY THROUGH FRIDAY...THE UPPER RIDGE GETS A BIT FLATTENED TODAY
WHEN SHORT WAVE ENERGY MOVES THROUGH. THE PASSAGE OF THIS FEATURE
WILL CAUSE THE SURFACE GRADIENT TO TIGHTEN FURTHER...ESPECIALLY
ALONG THE NORTHERN ROCKY MOUNTAIN FRONT. THE RESULT WILL BE
INCREASING WINDS AND HAVE UPGRADED THE HIGH WIND WATCH TO A HIGH
WIND WARNING FOR ZONE 9 ONLY. SOME LIGHT SNOW OVER THE WESTERN
MOUNTAINS WILL ALSO ACCOMPANY THE TROF PASSAGE. THE UPPER RIDGE
WILL QUICKLY REBUILD OVER THE WESTERN UNITED STATES ON THURSDAY
WITH THE COUNTY WARNING AREA UNDER A SOMEWHAT UNSETTLED NORTHWEST
FLOW ALOFT. SOME PRECIPITATION WILL OCCUR OVER THE MOUNTAINS WHILE
THE PLAINS REMAIN GENERALLY DRY DUE TO DOWNSLOPE INFLUENCES.
ANOTHER WEAK SHORT WAVE WILL MOVE THROUGH THE FLOW ON FRIDAY WITH
DOWNSLOPE WINDS AGAIN INHIBITING ANY PRECIPITATION. TEMPERATURES
WILL REMAIN ABOVE SEASONAL AVERAGES. EMANUEL

FRIDAY NIGHT THROUGH MONDAY NIGHT...MODELS INDICATE THAT A
PROGRESSIVE PATTERN IS GOING TO BE OVER AREA THROUGH WEEKEND AND
INTO NEXT WEEK. UPPER LEVEL RIDGE OVER AREA FRIDAY NIGHT SHIFTS
QUICKLY TO THE EAST AS UPPER LEVEL LOW OVER PACIFIC NORTHWEST MOVES
TOWARDS MONTANA SATURDAY. AMPLE MOISTURE WITH THIS SYSTEM TO START
OUT OVER THE WESTERN MOUNTAINS AND MOVE OVER THE ENTIRE CWA DURING
THE DAY ON SATURDAY. TEMPERATURES START OUT WARM FOR MAINLY RAIN
SHOWERS OVER THE PLAINS TURNING TO SNOW BY SATURDAY NIGHT. NORTHWEST
FLOW ALOFT SUNDAY AS NEXT UPPER LEVEL RIDGE BUILDS IN OVER PACIFIC
NORTHWEST COAST. RIDGE MOVES OVER WESTERN MONTANA BY SUNDAY NIGHT
AND OVER OUR CWA BY MONDAY MOVING EASTWARD BY MONDAY NIGHT.
TEMPERATURES WILL FLUCTUATE AS DOWNSLOPE WINDS WILL WARM THE AIR
MONDAY. CAMP

TUESDAY THROUGH WEDNESDAY...MODELS ARE IN BASIC AGREEMENT DURING
THIS PERIOD. A HIGH AMPLITUDE UPPER LEVEL RIDGE...JUST OFF THE WEST
COAST...DRIFTS EAST DURING THE PERIOD AS AN UPPER LEVEL TROUGH
DEEPENS OVER THE MIDWEST. THIS RESULTS IN A NORTHWESTERLY FLOW ALOFT
ACROSS THE FORECAST AREA. DISTURBANCES IN THIS FAIRLY MOIST FLOW ARE
EXPECTED TO PRODUCE UNSETTLED CONDITIONS WITH MOSTLY CLOUDY SKIES
AND ISOLATED SNOW SHOWERS FOR MOST OF THE FORECAST AREA. THERE IS A
LITTLE BETTER CHANCE OF PRECIPITATION OVER MOST MOUNTAINS. THIS IS A
COOL PATTERN AND A MODIFIED ARCTIC BACKS INTO OUR NORTHEAST ZONES
WEDNESDAY. TEMPERATURES WILL COOL A LITTLE BELOW SEASONAL
AVERAGES...EVEN COLDER NORTHEAST.  EK

.AVIATION...
UPDATED 0545Z.
AN UPPER LEVEL RIDGE WILL REMAIN CENTERED OVER THE PACIFIC COAST
STATES INTO THE ROCKIES THROUGH WEDNESDAY EVENING...CONTINUING THE
MAINLY MID TO HIGH LEVEL CLOUDINESS OVER NORTH CENTRAL AND SOUTHWEST
MONTANA. LINGERING LOW LEVEL MOISTURE MAY CAUSE AREAS OF MVFR
CONDITIONS IN FOG TO DEVELOP OVERNIGHT NEAR THE KBZN TERMINAL.
WESTERLY DOWNSLOPE WINDS WILL INCREASE EAST OF THE ROCKIES DURING
THE PERIOD...ESPECIALLY AFTER 18Z...KEEPING THE EAST SLOPES OF THE
ROCKIES DRY BUT WINDY. DISTURBANCES IN THE WEST-NORTHWEST FLOW ALOFT
WILL OBSCURE THE HIGHER PEAKS OF THE ROCKY MOUNTAIN FRONT IN AREAS
OF SNOW. ONE DISTURBANCE WILL ALSO BRING A CHANCE OF PRECIPITATION
TO THE EASTERN TERMINALS (KHVR AND KLWT) LATE TONIGHT THROUGH EARLY
WEDNESDAY MORNING. A SHORTWAVE TROUGH WILL THEN FLATTEN THE RIDGE
AFTER 22Z WEDNESDAY AND BRING A CHANCE FOR PRECIPITATION TO THE KHVR
TERMINAL AREA...AS WELL AS TO SOUTHWEST MONTANA (KHLN AND KBZN
TERMINALS).  COULSTON
