.PREV DISCUSSION... (ISSUED 530 PM MDT FRI OCT 27 2006)

DISCUSSION...
TONIGHT THROUGH SUNDAY NIGHT...A FAST NORTHWEST FLOW ALOFT WILL
CONTINUE OVER THE AREA THROUGH SATURDAY...KEEPING RELATIVELY MILD
TEMPERATURES IN PLACE OVER THE FORECAST AREA WITH GENERALLY DRY
CONDITIONS. AN UPPER LEVEL TROUGH IN THE GULF OF ALASKA WILL MOVE
INTO WESTERN BC LATE SATURDAY THROUGH SATURDAY NIGHT THEN INTO THE
NORTHERN ROCKIES SUNDAY AND SUNDAY NIGHT. WINDS ALOFT INCREASE
SIGNIFICANTLY AS THE UPPER TROUGH APPROACHES LATE SATURDAY WITH
STRONG WINDS BECOMING LIKELY ALONG THE ROCKY MTN FRONT AND ADJACENT
PLAINS THROUGH SATURDAY NIGHT AND WILL ISSUE A HIGH WIND WATCH TO
HIGHLIGHT THIS. AS THE UPPER TROUGH MOVES INTO THE REGION SUNDAY
AN AREA OF SURFACE LOW PRESSURE WILL MOVE EAST ALONG THE CANADIAN
BORDER WITH A STRONG COLD FRONT DROPPING SOUTH ACROSS THE STATE
LATE SUNDAY THROUGH SUNDAY NIGHT. THERE STILL IS SOME DISAGREEMENT
AMONG THE MODELS ON THE TIMING OF THE CANADIAN FRONT WHICH WILL
HAVE A LARGE IMPACT ON TEMPERATURES SUNDAY...HOWEVER POPS WERE
INCREASED ACROSS MUCH OF THE AREA LATE SUNDAY THROUGH SUNDAY
NIGHT AS UPSLOPE PRECIPITATION DEVELOPS BEHIND THE FRONT. WINDS
WILL SHIFT TO THE NORTH WITH THE FRONTAL PASSAGE AND CONTINUE TO
BE GUSTY FOR SEVERAL HOURS...CREATING AREAS OF BLOWING SNOW FOR
A PERIOD SUNDAY NIGHT. THIS WILL BE MONITORED BY LATER SHIFTS FOR
POSSIBLE HIGHLIGHTS. HOENISCH

MONDAY THROUGH WEDNESDAY...NW FLOW ALOFT IS OVER THE AREA THEREAFTER.
ALTHOUGH MODELS DISAGREE ON SOME EMBEDDED WEATHER DISTURBANCES
THEY KEEP THE AIRMASS PRETTY DRY SO HAVE LOWERED SOME POPS. ON
WEDNESDAY THE AREA SHOULD BEGIN TO FEEL THE INFLUENCE OF AN
UPSTREAM UPPER RIDGE. WILL GO WITH A DRY FORECAST. WEDNESDAY NIGHT
COULD ALSO BE DRY BUT DID NOT HAVE ENOUGH CONFIDENCE TO REMOVE THE
MENTION OF PRECIPITATION OVER THE NW MOUNTAINS AND ALSO OVER A FEW
MOUNTAINS IN SW MT. GENERALLY LOWERED TEMPERATURES FOR MUCH OF THE
PERIOD. BLANK

THURSDAY THROUGH FRIDAY...MODELS CONTINUE TO BE IN FAIR AGREEMENT
DURING THIS PERIOD.  A BROAD RIDGE BUILDS OVER THE PACIFIC NORTHWEST
DRIFTING EAST TO THE NORTHERN ROCKIES FRIDAY.  WEAK DISTURBANCES IN
A COOL WEST NORTHWESTERLY FLOW ARE EXPECTED TO INFLUENCE THE
FORECAST AREA.  THIS SHOULD RESULT IN PARTLY TO MOSTLY CLOUDY SKIES
WITH ISOLATED RAIN OR SNOW SHOWERS...MAINLY OVER OR NEAR THE WESTERN
AND SOUTHWESTERN MOUNTAINS...WITH A FEW OVER THE CENTRAL MOUNTAINS
FRIDAY.  DOWNSLOPE WINDS SHOULD HELP KEEP THE PLAINS AND LARGER
VALLEYS DRY.  TEMPERATURES WILL WARM TO JUST A FEW DEGREES BELOW
SEASONAL AVERAGES BY FRIDAY.  EK
