AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
1110 AM MST SUN NOV 12 2006

UPDATED AVIATION SECTION ONLY

.DISCUSSION...NO UPDATES NEEDED THIS MORNING. CURRENT FORECAST IS
ON TRACK WITH PACIFIC MOISTURE IN A WESTERLY FLOW ALOFT IMPACTING
THE WESTERN MOUNTAINS. BREEZY CONDITIONS WILL CONTINUE OVER THE
PLAINS WITH INCREASING MID AND HIGH LEVEL CLOUDS THROUGH THE
PERIOD. MPJ

&&

.AVIATION...
UPDATED 1810Z.
STRONG WESTERLY FLOW ALOFT TO CONTINUE OVER NORTH CENTRAL AND
SOUTHWEST MONTANA THROUGH 18Z MONDAY. MAINLY HIGH CLOUDS WILL MOVE
OVER THE AREA THROUGH 00Z MONDAY WITH WIDESPREAD MID CLOUDS ALONG
AND WEST OF THE CONTINENTAL DIVIDE...AS CONDITIONS REMAIN MAINLY
VFR. A COUPLE OF WEAK DISTURBANCES WILL THEN MOVE THE AREA OVERNIGHT
INTO MONDAY MORNING...SPREADING MID CLOUDS OVER THE ENTIRE AREA.
BASES WILL GENERALLY LOWER...BUT PLAINS AREAS WILL STILL REMAIN VFR
AS SOUTHWESTERLY DOWNSLOPING WINDS WILL PREVENT THEM FROM GETTING
TOO LOW. HOWEVER...MID LEVEL CLOUDINESS WILL LOWER ENOUGH ACROSS
WESTERN AND SOUTHWEST MONTANA THAT MOUNTAIN TOPS WILL GENERALLY BE
OBSCURED BY CLOUDS AND PRECIPITATION...AND VALLEYS WILL HAVE
OCCASIONAL MVFR CONDITIONS WITH A CHANCE OF PRECIPITATION.  COULSTON

&&

.PREV DISCUSSION... (ISSUED 425 AM MST SUN NOV 12 2006)

DISCUSSION...

TODAY TROUGH TUESDAY...AN UPPER LEVEL TROF IN THE GULF OF ALASKA
WILL CONTINUE TO MAINTAIN MOIST WESTERLY FLOW ALOFT THROUGH EARLY
THIS WEEK. AT LEAST TWO POTENT SHORTWAVES EMBEDDED IN THE FLOW WILL
BRING SIGNIFICANT PRECIPITATION TO THE WESTERN MOUNTAINS OVER THE
NEXT TWO DAYS. THE FIRST SHORTWAVE IS THE WEAKER OF THE TWO AND WILL
TAKE A NORTHERN TRACK ACROSS THE PACIFIC NW AND BC TODAY. WITH A
STRONG JET MAX AND PLENTIFUL MOISTURE AS SEEN IN WATER VAPOR
IMAGERY...EXPECT SNOW TO DEVELOP OVER THE NORTHERN ROCKY MTN FRONT
THIS MORNING AND CONTINUE THROUGH THIS EVENING. SEVERAL INCHES OF
SNOW ARE EXPECTED IN THE GLACIER PARK AREA WITH WINDS INCREASING AS
WELL FOR LOCAL BLOWING AND DRIFTING SNOW. AFTER A SHORT BREAK THIS
EVENING...THE MORE POTENT SHORTWAVE ENTERS THE PACIFIC NW TONIGHT
WITH THE UPPER LEVEL FEATURE AND A STRONG SURFACE LOW TRACKING ALONG
THE CANADIAN BORDER ON MONDAY. THIS SYSTEM WILL ALSO BRING ABUNDANT
MOISTURE TO THE ENTIRE ROCKY MTN FRONT WITH SIGNIFICANT BLOWING AND
DRIFTING OF SNOW. MODEL PRECIP AMOUNTS ALONG NORTHERN PORTIONS OF
THE CONTINENTAL DIVIDE RANGE FROM .50 TO OVER 1.5 AT HIGHER
ELEVATIONS...YIELDING SNOW AMOUNTS OF 8-18 WITH OVER 2 FEET
POSSIBLE AT THE HIGHEST ELEVATIONS THROUGH THE NEXT 36 HRS. WILL
ISSUE A WINTER STORM WARNING TO HIGHLIGHT THIS. CLOUDS WILL
INCREASE TODAY OVER THE REMAINDER OF THE FORECAST AREA AS PACIFIC
MOISTURE INCREASES OVER THE REGION. DOWNSLOPE WINDS WILL INCREASE
OVER THE PLAINS...LIMITING MUCH OF THE PRECIPITATION FROM THESE
SYSTEMS TO JUST SOME LIGHT SHOWERS OVER EASTERN ZONES MONDAY AND
KEEPING TEMPERATURES A FEW DEGREES ABOVE SEASONAL AVERAGES. HOENISCH

TUESDAY NIGHT THROUGH FRIDAY NIGHT...UPPER LEVEL RIDGE TO BUILD IN
TUESDAY NIGHT AND WEDNESDAY FOR WARM AND DRY CONDITIONS. DOWNSLOPE
CONDITIONS WEDNESDAY NIGHT AND THURSDAY AS A SURFACE LOW PASSAGES TO
THE NORTH OF MONTANA. EXPECT MAINLY MOUNTAIN PRECIPITATION BUT
CANNOT RULE OUT A SLIGHT CHANCE OF PRECIPITATION OVER THE EASTERN
ZONES. DOWNSLOPE AREAS WILL SEE VERY LITTLE PRECIPITATION. WESTERLY
FLOW THURSDAY NIGHT AND FRIDAY WITH UPPER LEVEL RIDGE BUILDING BACK
OVER THE AREA FRIDAY NIGHT. TEMPERATURES WILL BE NEAR TO SLIGHTLY
ABOVE SEASONAL AVERAGES THROUGH THE PERIOD. CAMP

SATURDAY THROUGH SUNDAY...MODEL INCONSISTENCIES DURING THIS PERIOD
COMPLICATE THE FORECAST.  WENT WITH A COMPROMISE OF A BROAD UPPER
LEVEL TROUGH TO PERSIST OVER THE WESTERN U.S. THROUGH SUNDAY.  A
FAIRLY MOIST BUT STRONG SOUTHWESTERLY FLOW ALOFT OVER THE FORECAST
AREA...IS EXPECTED TO RESULT IN PARTLY TO MOSTLY CLOUDY SKIES WITH
ISOLATED TO SCATTERED RAIN OR SNOW SHOWERS...MAINLY OVER AND NEAR
THE MOUNTAINS.  DOWNSLOPE WINDS SHOULD HELP KEEP THE PLAINS AND
LARGER VALLEYS MOSTLY DRY.  TEMPERATURES WILL BE A SEVERAL DEGREES
ABOVE SEASONAL AVERAGES.  EK
