AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
308 PM MST FRI NOV 30 2012

.DISCUSSION...

TONIGHT THROUGH SUNDAY...COPIOUS AMOUNTS OF PACIFIC MOISTURE
CONTINUE TO STREAM OVER MONTANA WITH RAIN AND SNOW OVER THE
MOUNTAINS THIS AFTERNOON AND OVERCAST SKIES ELSEWHERE THOUGH SOME
SHOWERS HAVE ALSO BEEN OCCURRING NEAR LEWISTOWN. UPGRADED THE
WINTER STORM WATCH TO A WINTER STORM WARNING FOR FAR SOUTHWEST
MONTANA AS PERIODS OF WET SNOW AND RAIN WERE BEGINNING TO IMPACT
AREA ROADWAYS. THIS WARNING WILL CONTINUE THROUGH SUNDAY NIGHT. SHOWERS
ARE ALSO OCCURRING IN THE VICINITY OF HAVRE AND WITH TEMPERATURES
NEAR FREEZING AND WEAK OVERRUNNING THERE IS A SMALL POSSIBILITY
FOR LIGHT FREEZING RAIN OR DRIZZLE. DOWNSLOPING WINDS SHOULD KEEP
MOST OF NORTH- CENTRAL MONTANA DRY THOUGH THERE WILL BE SOME
PRECIPITATION NOT REACHING THE GROUND. TEMPERATURES REMAIN ABOVE
SEASONAL AVERAGES TODAY AND WILL CONTINUE THROUGH AT LEAST SUNDAY
BEFORE A COLD FRONTAL PASSAGE. MUCH OF THE SHOWER ACTIVITY TODAY
IS OCCURRING WITH AN UPPER-LEVEL SHORTWAVE AND SNOW HAS BEEN
REPORTED ABOVE ELEVATIONS OF 6000 FEET. HEAVIER SNOW WAS REPORTED
OVER CHIEF JOSEPH PASS EARLIER THIS AFTERNOON WITH ROADWAYS SNOW-
COVERED AND SLICK SO ISSUED A WINTER WEATHER ADVISORY FOR SNOW AND
BLOWING SNOW THAT WILL BE IN EFFECT THROUGH 7 PM MST THIS EVENING.
SNOW ACCUMULATIONS UP TO 6 INCHES ARE POSSIBLE FOR CHIEF JOSEPH
PASS AND SURROUNDING AREAS. THIS FIRST SHORTWAVE WILL EXIT LATE
TONIGHT AND PRECIPITATION WILL TAPER. ANOTHER SHORTWAVE TROUGH
WILL MOVE ACROSS THE FORECAST AREA ON SATURDAY AND BRING ANOTHER
SURGE OF MOISTURE...HOWEVER BEST PRECIPITATION CHANCES WILL ONCE
AGAIN BE CONFINED TO THE MOUNTAINS ACROSS SOUTHWEST MONTANA
INCLUDING WEST YELLOWSTONE AS WELL AS FOR AREAS ALONG THE
CONTINENTAL DIVIDE. DOWNSLOPING WILL LIMIT PRECIPITATION OVER THE
PLAINS AND MID-LEVEL WINDS WILL START TO INCREASE ALONG THE ROCKY
MOUNTAIN FRONT AND A HIGH WIND WATCH REMAINS IN EFFECT.

A MORE SIGNIFICANT STORM SYSTEM WILL MOVE INTO THE AREA LATE
SATURDAY NIGHT THROUGH SUNDAY NIGHT AS A TROUGH OF LOW PRESSURE
AND ASSOCIATED SURFACE COLD FRONT MOVE THROUGH THE AREA. THIS
SYSTEM WILL BE A VERY FAST-MOVING SYSTEM WITH WIDESPREAD STRONG
WINDS ANTICIPATED AND A HIGH WIND WATCH IS IN EFFECT FOR THE
ENTIRE FORECAST AREA BEGINNING LATE SATURDAY NIGHT THROUGH SUNDAY
NIGHT. WIND GUSTS UP TO 60 MPH ARE POSSIBLE. DURING THE DAY ON
SUNDAY...SURFACE TEMPERATURES WILL REMAIN ABOVE AVERAGE OVER THE
PLAINS AND SOME VALLEYS ACROSS SOUTHWEST MONTANA SO PRECIPITATION
SHOULD BE MAINLY RAIN...HOWEVER BY SUNDAY EVENING TEMPERATURES
WILL QUICKLY FALL AND CHANGE PRECIPITATION OVER TO SNOW THOUGH
LITTLE SNOW ACCUMULATIONS ARE EXPECTED IN THIS AREA AS
PRECIPITATION SHOULD BE TAPERING BY THAT TIME. THERE IS HOWEVER
THE POSSIBILITY FOR ROADWAYS TO FREEZE AS THE TEMPERATURES FALL
BELOW FREEZING. ACROSS THE MOUNTAINS ACROSS SOUTHWEST MONTANA
INCLUDING WEST YELLOWSTONE...HEAVY SNOW WITH ACCUMULATIONS OF ONE
TO TWO FEET ARE POSSIBLE. THE COMBINATION OF HEAVY SNOW AND STRONG
WINDS MAY ALSO CAUSE NEAR BLIZZARD CONDITIONS. THERE IS THE
POTENTIAL FOR HEAVY SNOW ALONG THE ROCKY MOUNTAIN FRONT AS WELL SO
HAVE ADDED A WINTER STORM WATCH FOR THESE AREAS DUE TO THE
COMBINATION OF FORECASTED SNOW AND STRONG WINDS. SIGNIFICANT
IMPACTS TO TRAVEL...ESPECIALLY OVER MOUNTAIN PASSES AS WELL AS
OUTDOOR RECREATION ARE EXPECTED ALONG THE CONTINENTAL DIVIDE AND
MOUNTAINS ACROSS FAR SOUTHWEST MONTANA. WILL CONTINUE TO MONITOR
AND UPDATE AS NECESSARY. MLV

SUNDAY NIGHT THROUGH FRIDAY...MEDIUM RANGE MODELS ARE IN REASONABLE
AGREEMENT THROUGH THE MIDDLE OF NEXT WEEK WITH THE USUAL SPREAD IN
TIMING/AMPLITUDE DEVELOPING LATER NEXT WEEK AS A PROGRESSIVE
WESTERLY FLOW ALOFT CONTINUES OVER THE REGION. THE LONGWAVE UPPER
LEVEL TROUGH CURRENTLY OFF THE WEST COAST OPENS UP WITH A STRONGER
WAVE AND UPPER LEVELS JET MAXIMUM MOVING QUICKLY NE ACROSS THE
NORTHERN ROCKIES SUNDAY NIGHT. MODELS ARE IN RELATIVELY CLOSE
AGREEMENT NOW DEPICTING THE TRACK OF THE SURFACE LOW ASSOCIATED WITH
THIS ENERGY TRACKING EAST ALONG THE CANADIAN BORDER WITH THE MID
LEVEL CIRCULATION FURTHER NORTH IN ALBERTA AND STRONG WEST TO
SOUTHWEST FLOW TO THE SOUTH OVER NORTH CENTRAL AND SW MT LATE SUNDAY
THROUGH SUNDAY NIGHT. A WIDESPREAD HIGH WIND EVENT APPEARS LIKELY
LATE SUNDAY THOUGH SUNDAY EVENING AS THE PACIFIC FRONT MOVES ACROSS
THE AREA. ANY SIGNIFICANT PRECIPITATION WILL GENERALLY BE CONFINED
TO THE MTNS SUNDAY NIGHT...WITH STRONG WEST FLOW LIMITING
PRECIPITATION EAST OF THE ROCKIES TO SHOWERS. A SLIGHTLY COOLER
AIRMASS MOVES IN BEHIND THE FRONT ON MONDAY...BUT AFTERNOON
TEMPERATURES WILL STILL BE ABOVE AVERAGE FOR EARLY DECEMBER. WEAK
UPPER LEVEL RIDGING MONDAY THROUGH TUES NIGHT WILL KEEP MUCH OF THE
AREA DRY WITH PRECIPITATION MAINLY LIMITED TO OCCASIONAL SNOW
SHOWERS ALONG AND WEST OF THE CONTINENTAL DIVIDE. TEMPERATURES WILL
WARM BACK TO WELL ABOVE AVERAGE LEVELS BY TUESDAY AND REMAIN MILD
TUESDAY NIGHT AS WINDS INCREASE AGAIN AHEAD OF THE NEXT PACIFIC
UPPER LEVEL TROUGH...WHICH SHOULD MOVE INLAND DURING THE
WEDNESDAY/THURSDAY PERIOD. ANOTHER PERIOD OF STRONG WINDS AND MTN
SNOW IS POSSIBLE AS THIS SYSTEM MOVES ACROSS THE AREA LATE
WEDNESDAY. AS THE UPPER LEVEL TROUGH PROGRESSES INLAND THURSDAY AND
FRIDAY MODELS DIFFER SOME WITH THE AMPLITUDE OF THE TROUGH...HOWEVER
TEMPERATURES SHOULD COOL BACK CLOSER TO SEASONAL AVERAGES WITH ANY
PRECIPITATION APPEARING LIGHT. HOENISCH

&&

.AVIATION...
UPDATED 1800Z.
EXPECT GENERALLY VFR CONDITIONS. A WEATHER DISTURBANCE ALOFT WILL
MOVE THROUGH THE AREA TODAY BRINGING A FEW SHOWERS TO THE PLAINS
WITH SCATTERED SHOWERS FOR THE SOUTHWEST VALLEYS. OTHERWISE FOR
THOSE TWO AREAS EXPECT MOSTLY DRY CONDITIONS TONIGHT INTO EARLY
SATURDAY MORNING. FOR THE MOUNTAINS EXPECT CONTINUED PERIODS OF SNOW
WITH GENERAL OBSCUREMENT. EXPECT AT LEAST PATCHY FOG FROM KCTB TO
KHVR TONIGHT INTO SATURDAY MORNING. IFR CONDITIONS WILL BE POSSIBLE
IN THE FOG. ALTHOUGH THE MENTION OF FOG IN THE KCTB AND KHVR TAFS IS
AFTER 09Z BE AWARE THAT FOG COULD OCCUR AS EARLY AS 02Z. GUSTY WINDS
TO 50 KNOTS WILL BE POSSIBLE ALONG THE ROCKY MOUNTAIN FRONT
BEGINNING EARLY SATURDAY MORNING. BLANK
