AREA FORECAST DISCUSSION

1105 PM MST SAT NOV 29 2008

...UPDATE TO AVIATION...

.UPDATE...
FOR TONIGHT NORTHWEST FLOW ALOFT IS OVER THE FORECAST AREA. THERE
CONTINUES TO BE QUITE A BIT OF CLOUDINESS OVER SOUTHWEST MONTANA.
HOWEVER AS OF MID-EVENING THERE WAS NOT MUCH CLOUDINESS ALONG THE
EAST SLOPES OF THE ROCKY MOUNTAINS SO WILL GO WITH A FORECAST OF
LESS SKY COVER FOR THE REST OF THIS EVENING THERE. MODELS STILL
INDICATE AN INCREASE IN CLOUDINESS IN THAT REGION BY MORNING SO
WILL LEAVE THE MOSTLY CLOUDY FORECAST FOR LATE TONIGHT ALONE.
BASED ON RADAR AND ALSO LATEST FORECAST GUIDANCE WILL INCREASE THE
THREAT OF PRECIPITATION OVER A PORTION OF THE MOUNTAINS OF CENTRAL
MONTANA. WILL ALSO BE ADDING NEAR RECORD HIGH TEMPERATURES FOR
PORTIONS OF THE AREA ON MONDAY. REMAINDER OF THE FORECAST LOOKS OK
AND IN PARTICULAR THE HIGH WIND WATCH FOR SUNDAY NIGHT THROUGH
MONDAY NIGHT. BLANK

&&

.AVIATION...
UPDATED 0605Z.
A MOIST NORTHWESTERLY UPSLOPE FLOW WILL KEEP AREAS OF MID AND HIGH
LEVEL CLOUDINESS OVER MOST OF NORTH CENTRAL...CENTRAL...AND
SOUTHWEST MONTANA THROUGH SUNDAY EVENING...FOR CONTINUED MAINLY VFR
CONDITIONS. HOWEVER...CLOUDS AND SHOWERS WILL OBSCURE MOUNTAINS AT
TIMES AND BRING OCCASIONAL MVFR CEILINGS WITH PRECIPITATION TO THE
MOUNTAIN VALLEYS. WINDS WILL CONTINUE TO BE WESTERLY...BUT THEY MAY
ONLY BECOME GUSTY OVER THE PLAINS OF NORTH CENTRAL AND CENTRAL
MONTANA DURING THE DAY ON SUNDAY.  COULSTON

&&

.PREV DISCUSSION...
/ISSUED 445 PM MST SAT NOV 29 2008/

TONIGHT THROUGH MONDAY...AN UPPER LEVEL HIGH PRESSURE RIDGE
CONTINUES TO WARM THE AIRMASS.  SEVERAL WEAK UPPER LEVEL
DISTURBANCES CONTINUE TO MOVE THROUGH THE NORTHWEST FLOW ALOFT SO
ALTHOUGH THE THE AIRMASS CONTINUES TO DRY...WILL LEAVE SOME ISOLATED
POPS OVER SOUTHWEST MONTANA...AS WELL AS HIGHER POPS UP ALONG THE
DIVIDE. A JET APPROACHES THE ROCKIES SUNDAY NIGHT. THE MAIN OOMPH
REMAINS OVER THE CANADIAN ROCKIES BUT VERY STRONG WINDS WILL STILL
COVER MOST OF NORTH CENTRAL MONTANA. THE MODELS HAVE 50 KT PLUS
WINDS MOVING OVER THE ROCKIES BY 06Z MON AND 850 WINDS ALSO LOOK
STRONG WITH BOTH THE GFS AND NAM PUTTING 40 KT WINDS ACROSS THE
PLAINS. HELPING THE HIGH WIND SITUATION WILL BE A STABLE UPPER AIR
PROFILE OVER THE ROCKIES ALONG WITH A GOOD SHORT MOVING THROUGH THE
AREA. WITH STRONG SUSTAINED WINDS IN THE FORECAST...HIGHER
ELEVATIONS ACROSS MOST OF NORTH CENTRAL MONTANA SHOULD SEE WARNING
CRITERIA GUSTS. AT THE MOMENT...WILL COVER THE ENTIRE NORTH AND
CENTRAL ZONES IN A BROAD BRUSH WATCH AND TREAT TIMING DIFFERENCES IN
THE TEXT. IN GENERAL...HIGH WINDS SHOULD DEVELOP OVER THE ROCKIES
AFTER 06Z MON AND SPREAD INTO THE PLAINS MONDAY. THE AIRMASS
CONTINUES TO WARM THROUGH MONDAY AND HIGH TEMPS MONDAY SHOULD BE
NEAR RECORD VALUES. ZELZER

MONDAY NIGHT THROUGH THURSDAY NIGHT...MODELS CONTINUE TO ADVERTISE A
SIGNIFICANT PATTERN CHANGE TO OCCUR THIS PERIOD AS THE PERSISTENT
UPPER LEVEL RIDGE THAT HAS BEEN IN PLACE OVER THE REGION IS BROKEN
DOWN EARLY IN THE WEEK WITH A LONGWAVE TROUGH DEVELOPING OVER THE
CENTRAL CONUS THROUGH THE REMAINDER OF THE WEEK. MODELS CONTINUE TO
COME INTO BETTER AGREEMENT ON THE MON NIGHT THROUGH TUES PERIOD
WITH STRONG PHASED SHORTWAVE ENERGY BREAKING DOWN THE RIDGE MON
NIGHT/TUES. HIGH WINDS LOOK TO CONTINUE THROUGH MON NIGHT AS
GRADIENTS TIGHTEN WITH AN INITIAL SHORTWAVE MOVING ACROSS THE
REGION. THIS FIRST SHORTWAVE ALSO SPREADS SNOW ACROSS THE HIGHER
TERRAIN AND INTO SW MT LATE MON NIGHT. A SECONDARY SHORTWAVE DIGS SE
ACROSS THE AREA ON TUES...SENDING A STRONG CANADIAN COLD FRONT
ACROSS THE BORDER TUES MORNING...FOLLOWED BY A PERIOD OF SNOW FOR
MUCH OF THE FORECAST AREA WITH ENHANCED SNOWFALL IN FAVORED UPSLOPE
REGIONS OF CENTRAL MT. WITH GROWING CONFIDENCE IN THIS SOLUTION HAVE
INCREASED POPS SIGNIFICANTLY ON TUESDAY. MOST OF THE AREA SHOULD AT
LEAST SEE SOME LIGHT ACCUMULATIONS FROM THIS...WITH AN AREA OF MORE
SIGNIFICANT ACCUMULATIONS POSSIBLE OVER AND ALONG THE NORTH SLOPES
OF THE LITTLE BELTS AND SNOWIES WHERE UPSLOPE EFFECTS WILL BE
MAXIMIZED. STRONG PRESSURE RISES BEHIND THE FRONT WILL LIKELY CREATE
SOME BLOWING AND DRIFTING OF SNOW THROUGH THE DAY TUES AS WELL.
MUCH COOLER AIR SURGES IN BEHIND THE FRONT ON TUES WITH FALLING
TEMPS LIKELY DURING THE DAY IF CURRENT TIMING HOLDS AND MAX TEMPS ON
TUES ARE VERY NEAR MORNING LOWS FOR MUCH OF THE AREA. COOLER PATTERN
CONTINUES THROUGH THE REMAINDER OF THE WEEK WITH A GRADUAL
WARM-UP...HOWEVER MODELS DIVERGE WITH DETAILS OF THE NW FLOW ALOFT
PATTERN AFTER WED. HAVE KEPT TEMPS NEAR SEASONAL AVERAGES THROUGH
THURSDAY NIGHT...WITH POPS NEAR CLIMATOLOGICAL NORMS AS WELL.
HOENISCH

FRIDAY AND SATURDAY...MODELS ARE DISPLAYING BETTER AGREEMENT FOR THE
LONG RANGE FORECAST. NORTHWEST FLOW ALOFT OVER MONTANA IS
EXPECTED TO BRING IN PRECIPITATION FROM THE PACIFIC NORTHWEST.
MODELS DO DIFFER ON TIMING OF THE EVENT SO OPTED TO GO ABOVE
CLIMATOLOGY SATURDAY. TEMPERATURES WILL LIKELY BE ABOVE SEASONAL
THROUGH THE PERIOD. SAUCIER
