AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
1100 AM MST FRI FEB 24 2012

.UPDATE...
NO SIGNIFICANT CHANGES TO THE FORECAST THIS MORNING AS A RIDGE
BUILDS IN OVER THE AREA BRIEFLY TODAY. THE NEXT SYSTEM IS STILL
EXPECTED TO IMPACT THE AREA SATURDAY BRINGING A RETURN TO MORE
SEASONAL TEMPERATURES AND ADDITIONAL LIGHT PRECIPITATION ACROSS
MUCH OF THE AREA.
SUK

&&

.AVIATION...
UPDATED 1800Z.
EXPECT VFR CONDITIONS INTO THIS EVENING. FOR THIS AFTERNOON THERE
WILL BE SCATTERED SNOW SHOWERS OVER THE WESTERN MOUNTAINS. MOISTURE
WILL INCREASE AFTER MIDNIGHT FROM THE WEST. SNOW WILL BECOME
WIDESPREAD OVER THE WESTERN MOUNTAINS WITH AREAS OF MOUNTAIN
OBSCUREMENT. THESE CONDITIONS WILL SPREAD TO THE SOUTHWEST MOUNTAINS
BY SATURDAY MORNING. A PACIFIC COLD FRONT WILL MOVE EAST THROUGH THE
AREA LATE TONIGHT THROUGH SATURDAY MORNING. EXPECT SNOW SHOWERS WITH
THE FRONT OVER SOUTHWEST MONTANA AND THERE WILL BE AT LEAST LOCAL
MVFR OR POSSIBLY EVEN IFR CONDITIONS FOR THE VALLEYS. DO NOT THINK
THESE LOW CONDITIONS WOULD LAST MORE THAN AN HOUR OR TWO. SNOW
SHOWERS WILL BE LESS WIDESPREAD OVER THE PLAINS BUT EVEN THOSE AREAS
COULD SEE BRIEF MVFR OR EVEN IFR CONDITIONS WITH THE SNOW SHOWERS.
SHOULD MENTION THAT THERE WILL BE A THREAT OF MVFR CONDITIONS IN
SNOW OVER NORTHCENTRAL MONTANA LATE TONIGHT INTO SATURDAY MORNING
AHEAD OF THE COLD FRONT. CONFIDENCE IN FORECAST WINDS IS LOW DUE IN
PART TO MODEL DIFFERENCES WITH THE TIMING OF THE PACIFIC FRONT.

&&

.PREV DISCUSSION...
/ISSUED 449 AM MST FRI FEB 24 2012/

TODAY THROUGH SUNDAY...SATELLITE INDICATES A HIGH PRESSURE RIDGE
OVER THE EASTERN PACIFIC WHICH SHOULD MOVE OVER THE WEST COAST BY
THIS MORNING...AND OVER THE ROCKIES BY LATE FRIDAY AFTERNOON. THE
AIRMASS WILL BE RATHER DRY BUT THE NEXT WEATHER SYSTEM WILL BE
MOVING OVER THE WEST COAST BY MIDNIGHT. THIS LOW PRESSURE TROF WILL
MOVE OVER THE ROCKIES BY NOON SATURDAY. MOST OF THE DYNAMICS OF THIS
TROF WILL DIG SOUTH OF THE ZONES WITH QUITE WEAK FLOW ALOFT OVER THE
CENTRAL AND NORTHERN ZONES. AN ASSOCIATED COLD FRONT WILL PUSH INTO
THE HILINE LATE SATURDAY. SOME DIFFERENCES IN TIMING AS THE NAM
SWITCHES THE WINDS TO THE NORTHWEST WITH LOW LEVEL MOISTURE MOVING
INTO THE HILINE BY LATE SATURDAY AFTERNOON. HOWEVER...THE ECMWF AND
GFS ARE BOTH SLOWER WITH THE FRONT. WILL GO CONSERVATIVE ON MAX
TEMPS SATURDAY AS THEY ARE DEPENDENT UPON TIMING OF THE COLD FRONT.
UPSLOPE FLOW WILL NOT BE STRONG AND SNOWFALL AMOUNTS ACROSS THE
PLAINS WILL REMAIN RATHER LOW. WEAK CYCLONIC FLOW WILL REMAIN ALOFT
THROUGH SUNDAY AND A CHANCE OF SNOW WILL CONTINUE. WILL ISSUE A
WATCH FOR SNOW OVER THE NORTHERN ROCKIES...AN ADVISORY FOR PORTIONS
OF SOUTHWEST MONTANA. ZELZER

SUNDAY NIGHT THROUGH FRIDAY...EXPECT A FAIRLY QUIET WEEK OF WEATHER
OVER THE REGION FOR MUCH OF NEXT WEEK WITH NO MAJOR STORMS EXPECTED
FOR THE FIRST HALF OF THE WEEK. PRECIPITATION SHOULD BE GENERALLY
COMING TO AN END OVER MUCH OF THE AREA ON SUNDAY EVENING...AS THE
STORM SYSTEM FROM SATURDAY/SUNDAY MORNING EXITS THE REGION. WITH
SOME CLEARING EXPECTED BY EARLY MONDAY MORNING...OVERNIGHT LOWS WILL
BE ON THE COLD SIDE...ESPECIALLY IN AREAS THAT HAVE A FRESH SNOW
COVER. THERE WILL BE WEAK UPPER LEVEL DISTURBANCES MOVING THROUGH
THE REGION ALOFT FROM MONDAY THROUGH FRIDAY...BUT EACH DISTURBANCE
IS RATHER WEAK AND FAST MOVING...AND THE END RESULT WILL BE JUST
MINOR SNOWFALLS...AND MOST OF THE ACCUMULATING SNOWFALL CONFINED TO
THE MOUNTAINS. AFTERNOON TEMPERATURES WILL STILL BE WELL BELOW
NORMAL FOR MONDAY...BUT THEN GRADUALLY WARM BACK UP TO NEAR NORMAL
READINGS BY THE END OF THE WEEK. BRUSDA
