AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
305 AM MST SUN NOV 19 2006

.DISCUSSION...
TODAY THROUGH TUESDAY...UPPER LEVEL RIDGE AXIS IS OVER CENTRAL
MONTANA TODAY FOR DRY WEATHER AND MILD TEMPERATURES. THE RIDGE IS
SLOWLY PUSHED TOWARD EASTERN MONTANA TONIGHT AND SOUTHWEST FLOW
ALOFT SETS UP IN THE WEST AS AN UPPER LEVEL TROUGH APPROACHES THE
PACIFIC NORTHWEST. THE GRADIENT WILL TIGHTEN OVER THE ROCKY MOUNTAIN
FRONT AREA AND THE ASSOCIATED STRONG WINDS WILL MIX DOWN TO THE
SURFACE...WILL UPGRADE THE HIGH WIND WATCH TO A WARNING FOR TONIGHT
AND MONDAY. THERE WILL BE SOME MIXING DOWN OVER THE PLAINS BUT DOES
NOT APPEAR TO BE ENOUGH TO WARRANT A HIGHLIGHT THERE. TEMPERATURES
MONDAY WILL REMAIN QUITE MILD AS THE INFLUENCE OF THE RIDGE IS STILL
FELT...BUT WILL COOL SLIGHTLY FOR TUESDAY AS A WEAK COLD FRONT MOVES
THROUGH THE CWA. WILL SEE INCREASING PRECIPITATION OVER THE
MOUNTAINS UNDER THE SOUTHWEST FLOW BUT PRECIPITATION OVER THE PLAINS
WILL BE LIMITED TO JUST A SLIGHT CHANCE OF SHOWERS. THOMSON

TUESDAY NIGHT THROUGH FRIDAY NIGHT...THE PERIOD STARTS OUT WITH
SOUTHWEST FLOW ALOFT CONTINUING AS AN UPPER LEVEL TROF APPROACHES
THE WEST COAST. A RELATIVELY WEAK DISTURBANCE EMBEDDED WITHIN THIS
SOUTHWEST FLOW ALOFT WILL BRING A SLIGHT CHANCE OF PRECIPITATION TO
MOST OF THE AREA TUESDAY NIGHT. BY WEDNESDAY NIGHT...THE UPPER TROF
MOVES OVER THE AREA BRINGING ANOTHER CHANCE OF PRECIPITATION TO THE
AREA THROUGH THURSDAY NIGHT. THE FLOW ALOFT BECOMES NORTHWEST ON
FRIDAY IN THE WAKE OF THE UPPER TROF PASSAGE. A SURFACE LOW MOVES
ACROSS SOUTHERN CANADA FRIDAY THROUGH FRIDAY NIGHT BRINGING STRONG
DOWNSLOPE WINDS TO THE PLAINS. TEMPERATURES BEGIN THE PERIOD
SLIGHTLY ABOVE SEASONAL AVERAGES BUT COLDER AIR MOVES OVER THE AREA
BY WEEKS END AND AFTERNOON HIGHS WILL FALL BELOW SEASONAL AVERAGES.

SATURDAY THROUGH SUNDAY...MODELS CONTINUE TO CARRY A LONG WAVE
TROUGH OVER THE WEST WITH A WESTERLY FLOW ALOFT. THE PATTERN SEEMS
PROGRESSIVE WITH A SERIES OF SHORT WAVE TROUGHS MOVING THROUGH THE
FLOW ALOFT. GFS HAS A CANADIAN AIRMASS NEAR THE MONTANA BORDER  DURING
THE PERIOD...WITH A SERIES OF SURFACE LOWS MOVING THROUGH NORTHERN
AND CENTRAL MONTANA. THE POSITIONING OF THE SURFACE LOWS WILL MAKE
FORECASTING TEMPERATURES RATHER DIFFICULT. MODELS DO CONTINUE TO
PUSH MOST OF THE COLD AIR EAST OF MONTANA. COLDER THAN SEASONAL
AVERAGE TEMPERATURES ARE MORE LIKELY NEAR THE CANADIAN BORDER WITH
WARMER THAN AVERAGE OVER THE SOUTH. THE PLAINS OF NORTH CENTRAL
MONTANA IS LIKELY TO BE DRY SATURDAY WITH A CHANCE OF SNOW ON
SUNDAY AS THE COLDER AIR MAY MOVE SOUTH INTO NORTH CENTRAL MONTANA.
SCATTERED MOUNTAIN SNOW WILL CONTINUE THROUGH THE PERIOD WITH
ISOLATED SNOW SHOWERS IN THE SOUTHWEST VALLEYS. WILLIAMSON DC

.AVIATION...
UPDATED 0525Z.
THE UPPER LEVEL RIDGE WILL REMAIN OVER THE WESTERN CONUS THROUGH 06Z
MONDAY...CONTINUING THE MODERATE WESTERLY FLOW ALOFT. EMBEDDED
DISTURBANCES AND MOISTURE WILL INCREASE THE FLOW ALOFT THROUGH THE
PERIOD AND BRING INCREASING MID AND HIGH LEVEL CLOUDS TO THE AREA.
CONDITIONS WILL GENERALLY REMAIN VFR. HOWEVER...PATCHY FOG AND LOW
CLOUDS WILL CONTINUE TO CREEP INTO SOME VALLEYS OF FAR SOUTHWEST
MONTANA TONIGHT...FOR LOCAL MVFR TO IFR CONDITIONS THERE.
ALSO...SHOWERS WILL DEVELOP OVER THE WESTERN MONTANA MOUNTAINS AFTER
21Z SUNDAY FOR OCCASIONAL MVFR CONDITIONS THERE AS WELL. A SURFACE
TROUGH WILL DEVELOP TO THE LEE OF THE ROCKIES THROUGHOUT THE
PERIOD...FOR INCREASING SOUTHERLY WINDS ACROSS THE AREA (MAINLY
AFTER 12Z).  COULSTON
