AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
326 AM MST SUN JAN 11 2009

.SHORT TERM...VALID FOR TDY AND MON...

MOIST NORTHWEST FLOW MOVING INTO THE AREA TODAY. HAVE INCREASED
POPS TO LIKELY IN MOUNTAINS THROUGH THE DAY. LOOKS LIKE SEVERAL
INCHES OF SNOW SHOULD BE POSSIBLE AT HIGHER ELEVATIONS. HAVE
INTRODUCED SOME SLIGHT CHANCE IN WESTERN AND CENTRAL PLAINS AS
WELL...BUT DOWNSLOPE FLOW WILL KEEP MOST OF THE ACTIVITY LIMITED
TO A LIGHT SHOWER OR SPRINKLE AT BEST. ANOTHER STRONG WAVE MOVE
INTO THE AREA LATER THIS AFTERNOON AND TONIGHT. THIS WAVE WILL
PUSH A STRONG ALBERTA CLIPPER THROUGH THE DAKOTAS AND BRING STRONG
WINDS TO EASTERN ZONES AND A QUICK SHOT OF LIGHT SNOW. THIS WILL
RESULT IN A PERIOD OF SNOW AND BLOWING SNOW WITH REDUCED
VISIBILITIES IN EASTERN ZONES. CONSIDERED CHANGING HIGH WIND WATCH
TO A WINTER STORM WARNING AS IT LOOKS LIKE WINTER LIKE CONDITIONS
MAY BE THE MAIN CONCERN...BUT WILL KEEP THE HIGH WIND WATCH GOING
AND HIT THE WORDING OF HAZARDOUS WINTER CONDITIONS A BIT HARDER.
AS FAR AS HIGH WIND...IT WILL BE POSSIBLE...BUT LOOKS LIKE THE
MAIN INGREDIENTS ARE LACKING AND ALSO THE STRONGEST DYNAMICS COME
AT VERY UNFAVORABLE TIME FOR HIGH WINDS OVER NIGHT TONIGHT INTO
SUNDAY MORNING. THIS INCLUDES COLD AIR ADVECTION WHICH IS PROGGED
BY NAM TO HAVE A GLANCING BLOW TO BAKER AREA WITH BEST CAA NORTH
AND EAST IN DAKOTAS. PRESSURE RISES ARRIVE PRETTY LATE AROUND 18Z
WHEN 850 MB WINDS ARE DOWN BELOW 40 KNOTS. STRONGEST PERIOD OF 850
MB WINDS LOOKS TO BE AROUND 12Z AROUND 50 KNOTS DURING PERIOD OF
STRONGEST SURFACE INVERSIONS. END RESULT WILL BE A PERIOD OF SNOW
AND BLOWING SNOW REDUCING VISIBILITIES...BUT SHOULDNT BE A LONG
PERIOD FROM 4 TO 6 HOURS. CLIPPER WILL ALSO INCREASE WINDS ACROSS
THE AREA TODAY WITH WINDS GETTING TOO CLOSE TO ADVISORY FOR
COMFORT IN GAP AREAS. HAVE HAD A GUST TO 50 MPH OVERNIGHT TONIGHT
AND PRESSURE GRADIENT WILL INCREASE THROUGH THE MORNING AND PEAK
AROUND 18Z...SO THINK ADVISORY CRITERIA WILL BE MET.

COLD AIR GETS PULLED IN EASTERN ZONES MONDAY SO HAVE LOWERED
TEMPERATURES A BIT THERE FOR THE DAY. WILL BE A FAIRLY GOOD
WEST/EAST TEMPERATURES GRADIENT WITH 40S IN EASTERN ZONES. HAVE
KEPT ISOLATED POPS IN ACROSS THE PLAINS WITH THE NORTHWEST FLOW
OVER THE AREA. RASCH

.LONG TERM...VALID FOR TUE...WED...THU...FRI...SAT...

MAIN FORECAST CONCERN IN THE EXTENDED PERIOD CONTINUES TO BE
POTENTIAL SIGNIFICANT BACKDOOR COLD FRONT WEDNESDAY. THOUGH MODELS
HAVE BECOME MORE CONSISTENT WITH STRENGTH AND TIMING OF CLIPPER...
MUST STILL STRESS UNCERTAINTY WITH REGARD TO TEMPS AND POTENTIAL
SNOWFALL...DUE TO SUCH A HIGH AMPLITUDE PATTERN AND NORTHERLY FLOW
OVER US.

TUESDAY SHAPING UP TO BE A WARM/DRY/WINDY DAY. HAVE LOWERED POPS
FURTHER IN THE WEST DUE TO DOWNSLOPING. WINDS WILL BE PARTICULARLY
STRONG ALONG THE WESTERN FOOTHILLS WITH TIGHT GRADIENT SETTING UP
AND 700MB WINDS TO 50 KTS...THOUGH MID LEVEL NW FLOW DOES NOT
APPEAR TO BE LINKING TO THE SFC GRADIENT. HAVE RAISED WINDS A BIT
FROM KLVM TO K3HT AND EVEN AS FAR EAST AS KBIL. MIXING SHOULD BE
PROMOTED BY WEAK SHORTWAVE AND THE W-NW FLOW...AND COULD EASILY
SEE HIGH TEMPS NEAR 50F.

COUPLE OF EMBEDDED WAVES DROP THROUGH THE DEVELOPING HIGH AMPLITUDE
NORTH FLOW TUE NIGHT AND WED. THIS WILL ALLOW FOR A SURGE OF COLD
AIR INTO THE PLAINS...A CERTAINTY TO OUR EAST...WITH MAIN QUESTION
FOR US BEING HOW FAR WEST WILL A SURGE OF LOW LEVEL COLD AIR GO?
ECMWF AND CANADIAN RUNS HAVE ACTUALLY TRENDED A BIT MORE
AGGRESSIVE WITH THE COLD AIR...BUT THE GFS REMAINS SOMEWHAT
WEAKER...THOUGH ALL MODELS AGREE THAT FRONT WILL HOLD OFF UNTIL
WED AFTER 12Z. THIS WILL YIELD A MOSTLY DRY AND STILL MILD TUE
NIGHT. SHOULD SEE A PERIOD OF LIGHT SNOW IN OUR EAST ON WED WHERE
AN ARCTIC FRONTAL PASSAGE IS MOST LIKELY...WITH FALLING TEMPS THRU
THE DAY. WITH CYCLONIC FLOW ALOFT AND VERY HIGH SFC PRESSURES
ASSOCIATED WITH COLD AIR SURGE...STILL THINK AT LEAST A SHALLOW
ARCTIC WILL GET INTO MOST OF OUR AREA BY LATE WED...INCLUDING
BILLINGS. HOWEVER EVEN IF COLD FRONT MAKES IT ALL THE WAY WEST...
COULD VERY WELL BE TOO SHALLOW FOR PCPN. BUT IT DOES APPEAR A
BAROCLINIC ZONE WILL SET UP SOMEWHERE IN CENTRAL OR EAST PARTS...
SO WILL STAY WITH A MENTION OF SNOW THROUGH WED NIGHT INTO
THU...THOUGH IMPOSSIBLE AT THIS TIME TO TELL WHERE EXACTLY THIS
WILL HAPPEN. OTHER ISSUE IS HOW FAST THE FRONT WILL RETREAT TO THE
EAST. LATEST MODEL TRENDS ARE TO KEEP IT IN OUR EAST HALF THROUGH
THU...A DAY ON WHICH THERE WILL LIKELY BE A VERY WIDE RANGE OF
TEMPS FROM WEST TO EAST.

THINGS STILL LOOKING DRY/STABLE AND QUITE WARM BEGINNING FRI AND
CONTINUING THROUGH THE WEEKEND. MODELS AND ENSEMBLES IN GOOD
AGREEMENT IN SHOWING A STRONG RIDGE EXTENDING OVER THE NORTHERN
ROCKIES...SOMETHING WE HAVE NOT SEEN IN A LONG TIME. SO GOOD
CONFIDENCE HERE IN KEEPING THE FRI/SAT FORECAST DRY WITH WELL
ABOVE NORMAL TEMPS.

JKL

.AVIATION...

MOIST PACIFIC FLOW WILL BRING SOME SNOW AND FREQUENT OBSCURATIONS
TO THE CRAZY AND BEARTOOTH/ABSAROKA MTNS TODAY...SPREADING TO THE
BIG HORNS TONIGHT. VFR WILL PREVAIL FOR THE PLAINS TODAY...BUT A
COLD FRONT WILL BRING A BETTER CHANCE OF SNOW FOR THE LOWER
ELEVATIONS TONIGHT. LOCAL MVFR IS POSSIBLE FROM KBIL-KSHR
EASTWARD TONIGHT...AND A BRIEF PERIOD OF IFR OR LOWER IS POSSIBLE
THIS EVENING AT KMLS AND KBHK WHERE PCPN SHOULD BE HEAVIEST AND
MAY COMBINE WITH REDUCED VISIBILITY DUE TO BLOWING SNOW.

A PERIOD OF STRONG NW WINDS WILL DEVELOP IN EASTERN PARTS OF THE
FORECAST AREA BEHIND A COLD FRONT TONIGHT...AFFECTING KMLS AND
KBHK WITH GUSTS OF 35-45 KTS BEGINNING AFTER 00Z. OTHERWISE STRONG
SW-W WINDS WILL CONTINUE TO AFFECT LOCATIONS ALONG THE WESTERN
FOOTHILLS TODAY...INCLUDING KLVM AND K3HT. GUSTS OF 40-50 KTS
EXPECTED IN THESE AREAS DURING THE DAY TODAY...WITH A DECREASE IN
WINDS TONIGHT.
