AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
351 AM MST MON NOV 26 2007

.DISCUSSION...

TODAY THROUGH WEDNESDAY...WEAK UPPER RIDGING WILL MOVE OVER THE
AREA TODAY AHEAD OF AN UPPER TROF THAT APPROACHES THE WEST COAST.
ANY PRECIPITATION TODAY WILL BE CONFINED TO THE WESTERN MOUNTAINS.
THE UPPER TROF AND ASSOCIATED SURFACE LOW WILL MOVE ACROSS THE
AREA TONIGHT AND TUESDAY. THE HEAVIEST SNOW WILL FALL ABOVE 5000
FEET ALONG THE ROCKY MOUNTAIN FRONT AND OVER LEWIS AND CLARK
COUNTY. IN ADDITION TO THE SNOW...GUSTY WINDS OVER THIS AREA WILL
ALSO CAUSE AREAS OF BLOWING SNOW. THE WINTER STORM WATCH HAS BEEN
UPGRADED TO A WINTER STORM WARNING WITH A STARTING TIME OF 5 PM
MST TODAY. NORTHWEST FLOW ALOFT WILL DEVELOP OVER THE AREA
WEDNESDAY AS THE UPPER TROF EXITS TO THE EAST. TEMPERATURES WILL
CONTINUE NEAR SEASONAL AVERAGES TODAY BEFORE DROPPING WELL BELOW
SEASONAL AVERAGES TUESDAY AND WEDNESDAY. EMANUEL

WEDNESDAY NIGHT THROUGH SATURDAY NIGHT...MEDIUM RANGE MODELS
CONTINUE TO INDICATE A MAJOR AMPLIFICATION OF THE PATTERN ACROSS
NORTH AMERICA THIS PERIOD...FEATURING A DEEP TROUGH OVER MUCH OF
WESTERN AND CENTRAL NORTH AMERICA AS AN UPPER LEVEL RIDGE SHARPENS
AND AMPLIFIES INTO AK TOWARDS THE NORTH POLE. A COLD BUT MODIFIED
ARCTIC AIRMASS WILL MOVE SOUTH INTO THE THE STATE WEDNESDAY NIGHT
THROUGH THURSDAY. GFS MODEL HAS SOME FLUCTUATION WITH THE EXTENT OF
THIS HIGH OVER THE REGION...HOWEVER THE ECMWF KEEPS THE HIGH IN
PLACE EAST OF THE DIVIDE THROUGH THE PERIOD AND THIS SOLUTION IS
PREFERRED. STRONG SHORTWAVE MOVES ONSHORE IN THE PAC NW WED NIGHT AND
ACROSS ID/WY THURS/THURS NIGHT. THIS FEATURE LOOKS LIKE A GOOD SNOW
PRODUCER FOR SW MT ZONES WITH SOME LIGHTER OVERRUNNING SNOW TO THE
NORTH INTO CENTRAL MT AS WELL. HAVE INCREASED POPS THIS PERIOD FOR
ALL BUT THE NORTHERN THIRD OF THE CWA. AFTER THIS...THE MODIFIED
ARCTIC AIRMASS WILL LIKELY DEEPEN OVER THE AREA...AND WITH MOIST
NORTHERLY LOW LEVEL FLOW AND CYCLONIC FLOW ALOFT CANNOT RULE OUT
SOME VERY LIGHT SNOW AT TIMES THROUGH SATURDAY NIGHT...HOWEVER
AMOUNTS SHOULD BE VERY LIGHT. TEMPERATURES WILL COOL FROM NORTH TO SOUTH
WEDNESDAY NIGHT THROUGH THURSDAY AS THE COLD AIRMASS SETTLES
IN...WITH COLDEST TEMPERATURES TOWARDS THE WEEKEND AS THE AIRMASS
DEEPENS OVER THE REGION WITH BETTER CHANCES FOR CLEARING SKIES
DURING THE OVERNIGHT HOURS. EXACTLY HOW COLD IS STILL SOMEWHAT
UNCERTAIN DUE TO POSSIBLE CLOUDS/PRECIP AND FACT THAT THE AIRMASS
WILL BE SOMEWHAT MODIFIED...BUT HAVE LOWERED TEMPS AGAIN TONIGHT
THROUGH THE EXTENDED PERIOD...WITH LOW TEMPS GENERALLY NEAR ZERO
WITH HIGHS IN THE LOWER TEENS. HOENISCH

SUNDAY THROUGH MONDAY...MODELS START OUT IN FAIR AGREEMENT SUNDAY
BEFORE DIVERGING MONDAY. I LEANED TOWARD THE ECMWF SOLUTION WHICH
CONTINUES TO SHOW BETTER RUN TO RUN CONSISTENCY. A DEEP UPPER LEVEL
LOW OVER CENTRAL CANADA DIGS SOUTHWEST INTO SOUTHERN BC RESULTING IN
BACKING FLOW ALOFT DURING THIS PERIOD.  A FEW WEAK DISTURBANCES IN
THIS FLOW ALOFT SHOULD RESULT IN MOSTLY CLOUDY SKIES WITH ISOLATED
LIGHT SNOW SHOWERS OR FLURRIES OVER MUCH OF THE REGION...WITH SNOW
MORE WIDESPREAD OVER THE WESTERN AND SOUTHWESTERN MOUNTAINS. PARTS
OF OUR FAR NORTHERN AND EASTERN PLAINS WILL BE MOSTLY DRY. AN ARCTIC
AIRMASS OVER MOST OF THE FORECAST WILL BE RESPONSIBLE FOR
TEMPERATURES WELL BELOW SEASONAL AVERAGES. HOWEVER...BACKING FLOW AT
THE SURFACE MONDAY SHOULD HERALD THE BEGINNING OF SOME MODERATION IN
TEMPERATURES.  EK

.AVIATION...
UPDATED 0535Z.
A WEAK UPPER LEVEL TROUGH OF LOW PRESSURE IS CAUSING AN AREA OF SNOW
SHOWERS OVER CENTRAL MONTANA. THIS WILL BE EXITING THE AREA AFTER
09Z...BUT NOT BEFORE MVFR/IFR CONDITIONS EXPAND INTO THE KLWT AREA
THROUGH 09Z. AFTERWARDS...AN UPPER LEVEL HIGH PRESSURE RIDGE OVER
THE PACIFIC NORTHWEST WILL PUSH OVER THE AREA THROUGH MONDAY. VFR
CONDITIONS WILL PREVAIL OVER THE AREA AFTER 09Z.
