AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
435 AM MDT SAT NOV 3 2007

.SHORT TERM...VALID FOR TDY AND SUN...

WINDY PERIOD COMING UP FOR PORTIONS OF THE FORECAST AREA...AND
COLD FRONTAL PASSAGE EXPECTED SUNDAY. THE MODELS WERE SIMILAR WITH
OVERALL PATTERN THROUGH SUN NIGHT. FOR THIS MORNING...SHORTWAVE
MOVING SE OUT OF ALBERTA WILL BRING SOME LIFT AND MID LEVEL
MOISTURE TO THE NE ZONES. A FEW ECHOES ASSOCIATED WITH THIS WAVE
HAD DEVELOPED OVER NE MT EARLY THIS MORNING. LOW LEVELS VERY DRY
THIS MORNING WITH DEWPOINTS IN TEENS SO WOULD NOT EXPECT ANY MORE
THAN A SPRINKLE OR FLURRY AND HAVE ADDED THIS POSSIBILITY TO THE
NE ZONES THROUGH 18Z. LEE TROUGH DEEPENED OVER THE AREA LAST NIGHT BUT
WINDS AT KLVM HAVE STAYED BELOW ADVISORY CRITERIA DUE TO NW TO SE
ORIENTED SURFACE PRESSURE PATTERN. PRESSURE FALLS WERE EXITING THE
REGION AT 09Z.

AFTER THE WAVE EXITS E MT THIS MORNING...WILL HAVE FLAT DRY NW
FLOW OVER THE REGION THROUGH TONIGHT. MODELS INDICATED THAT 30-40
KT 850 MB JET WILL MOVE OVER E ZONES TODAY...SO EXPECT WINDY
CONDITIONS THERE. WARM DAY STILL ON TAP. HIGH TEMPS WERE IN GOOD
SHAPE BASED ON MIXING DOWN FROM NEAR 700 MB.

135 KT UPPER JET OFF BC COAST WILL REMAIN N OF THE AREA TODAY BUT
BEGIN TO SINK S TONIGHT. A COLD FRONT OVER BC TODAY WAS ALSO
FORECAST TO PUSH S TO MT/CANADIAN BORDER BY 12Z SUN ACCOMPANIED BY
A STRONG SHORTWAVE. LOW PRESSURE ALONG THE FRONT COMBINED WITH
HIGH PRESSURE OVER SE ID/W WY WILL SET UP ANOTHER FAVORABLE
PRESSURE GRADIENT FOR STRONG WINDS IN GAP FLOW AREAS TONIGHT. BY
06Z TONIGHT...50-60 700 MB JET WAS FORECAST TO MOVE OVER WESTERN
ZONES. MODEL SOUNDINGS INDICATED THAT THESE STRONG WINDS WILL
EXTEND DOWN QUITE LOW IN THE ATMOSPHERE...BELOW THE NIGHTTIME
INVERSION. AS A RESULT...HIGH WIND POTENTIAL WILL EXTEND TO
WHEATLAND AND JUDITH GAP AREAS. CHECKED SWEET GRASS COUNTY FOR
WIND POTENTIAL BUT MODELS HAD DIFFERING SOLUTIONS WITH THE WINDS
THERE SO WILL NOT HAVE A HIGHLIGHT. WILL UPGRADE HIGH WIND WATCH
TO A WARNING AND WILL BEGIN WARNING AT 03Z...AS WINDS LOOKED LIKE
THEY WOULD HOLD OFF TIL AFTER 00Z TONIGHT. MIN TEMPS LOOKED FINE
WITH VALUES ABOVE GUIDANCE IN WINDY AREAS.

NEXT FORECAST CHALLENGE WILL BE TIMING THE SUNDAY COLD FRONT
THROUGH THE AREA. FRONTS OFTEN COME THROUGH THE AREA FASTER THAN
MODELS PREDICT...OR THEY COME THROUGH AS TWO SEPARATE FRONTS. THE
MODELS WERE IN VERY GOOD AGREEMENT IN BRINGING THE FRONT S TO JUST
N OF THE FORECAST AREA BY 18Z THEN THROUGH MUCH OF THE REGION BY
00Z MON. GOING FORECAST REFLECTED THIS TIMING...BUT VERY COLD AIR
N OF BOUNDARY COULD CONTRIBUTE TO FASTER FRONTAL MOVEMENT. WILL
NOT CHANGE TIMING BUT WILL NEED TO WATCH SYSTEM FOR SIGNS OF
FASTER MOVEMENT. MORNING POPS NW STILL LOOKED GOOD BASED ON TRACK
OF FRONTOGENESIS AND DEEP RH. INCREASED POPS A BIT ACROSS THE N
FOR THE AFTERNOON AS SOME 850-700 MB FRONTOGENESIS AND RH COME
TOGETHER OVER THIS AREA. ALSO EXPANDED LOW POPS FURTHER SW AND S INTO
FOOTHILLS AND SHERIDAN COUNTY TO REFLECT A POSSIBLE FASTER FRONT.
LOWERED HIGH TEMPS ACROSS THE N AND RAISED THEM OVER THE S TO
COINCIDE WITH THE MODEL/S FRONTAL TIMING. KEPT THE HIGH WIND
WARNING GOING UNTIL 18Z WHEN INVERSION SHOULD BREAK AND STRONG
WINDS ALOFT WILL MOVE E. THERE WAS THE POSSIBILITY THAT STRONG
WINDS COULD MIX TO THE SURFACE OVER THE E SUN AFTERNOON. WILL
HIGHLIGHT THIS IN HWO FOR NOW AND HAVE LATER SHIFTS CONTINUE TO
EVALUATE SITUATION.

COLD FRONT...ASSOCIATED FRONTOGENESIS AND INSTABILITY WILL SETTLE
ALONG THE FOOTHILLS SUN NIGHT. SPLIT SUN NIGHT POPS INTO EVENING
AND OVERNIGHT PERIODS TO TIME BEST PRECIP CHANCES. BASED ON TIME
HEIGHT CROSS SECTIONS...HAD JUST A CHANCE OF PRECIP IN THE EVENING
OVER THE E...WITH LIKELY POPS OVER W. BEST CHANCES FOR SHERIDAN
WILL BE AFTER 06Z...SO REFLECTED THIS IN POP GRIDS. KEPT SLIGHT
CHANCE NE AFTER 06Z...AND LOWERED POPS TO CHANCE WEST EXCEPT KEPT
THEM HIGH OVER FOOTHILLS. LIKELY POPS OVER BIG HORNS LOOKED
REASONABLE AS N UPSLOPE FLOW BECOMES DEEPER WITH TIME OVER THIS
AREA. MODEL QPFS WERE NOT VERY HIGH...FROM SEVERAL HUNDREDTHS OF AN
INCH TO ABOUT 2 TENTHS OF AN INCH SUN NIGHT. WILL HAVE RAIN/SNOW
MIX THROUGH 06Z...THEN MOSTLY SNOW AFTER 06Z. DUE TO LOW QPF/S...QUICK
TIMING OF BEST FRONTOGENESIS AND INSTABILITY...AND BEST LIFT WELL
BELOW DENDRITIC GROWTH LAYER...NOT EXPECTING MUCH SNOW
ACCUMULATION OVER ANY AREA. MIN TEMPS IN 20S LOOKED REASONABLE
BASED ON GUIDANCE. ARTHUR

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

NOT MANY CHANGES TO THE EXTENDED FORECAST THIS MORNING. MODELS IN
PRETTY GOOD AGREEMENT UNTIL THE LATTER PART OF THE EXTENDED.

MONDAY...BOTH ECMWF AND GFS KEEPING A BAND OF PRECIPITATION
AROUND UNTIL MONDAY MORNING. INCREASED POPS SLIGHTLY IN THE
SOUTHWEST UNTIL NOON TO REFLECT SLOWER TREND OF MOVING PRECIP OUT
OF THE AREA. THEREAFTER PRECIP CHANCES RAPIDLY DECREASE WITH
DRIER AIR MOVING INTO THE AREA AND UPSLOPE FLOW BECOMING LESS
FAVORABLE. THEREFORE LOWERED POPS FOR MONDAY AFTERNOON. MADE ONLY
SLIGHT ADJUSTMENTS TO TEMPERATURES. LOOKS LIKE IT SHOULD BE A
FAIRLY CHILLY DAY...ESPECIALLY IN THE EAST. WINDS WILL DIMINISH
FROM WEST TO EAST DURING THE DAY WITH THE EASTERN ZONES REMAINING
GUSTY UNTIL MONDAY EVENING.

TUESDAY AND WEDNESDAY...AREA REMAINS UNDER NORTHWEST FLOW AS
RIDGE BUILDS OVER THE PACIFIC NORTHWEST. TEMPERATURES REBOUND
QUICKLY ON TUESDAY AND WARM EVER FURTHER ON WEDNESDAY. BOTH DAYS
SHOULD REMAIN DRY.

THURSDAY THROUGH SUNDAY...MODELS BRING SOME ENERGY DOWN FROM
CANADA AS RIDGE CONTINUES TO BUILD OVER PACIFIC NORTHWEST ON
THURSDAY. AFTER THIS...THEY DIVERGE QUITE A BIT SO LEFT CLIMO
LIKE POPS ACROSS MOST OF THE AREA...ESPECIALLY THE MOUNTAINS.
MILD TEMPERATURES SHOULD CONTINUE WITH ABOVE NORMAL READINGS
ACROSS THE AREA.

.AVIATION...

VRF CONDITIONS WILL PREVAIL TODAY. TIGHTENING PRESSURE GRADIENTS
DUE TO AN APPROACHING LOW PRESSURE SYSTEM WILL CAUSE GUSTY WINDS
ALONG THE FRONT RANGE...ESPECIALLY IN THE KLVM AREA. SOUTHWEST
WIND GUSTS WILL RANGE FROM 25 TO 35 KTS AND INCREASE TO 30 TO 40
KTS BY EVENING. GUSTS OF 20 TO 25 KTS WILL EXTEND INTO THE
PLAINS. OTHERWISE...NO OTHER HAZARDS EXPECTED. STOPPKOTTE
