AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
259 AM MDT MON MAR 24 2008

.SHORT TERM...VALID FOR TDY AND TUE...

MAIN CONCERN IN SHORT TERM IS WINDS. UPPER LEVEL JET INCREASING TO
IN EXCESS OF 100 KTS ACROSS THE PACIFIC NORTHWEST NOW AS ENERGY
DRIVING INTO WESTERN CANADA FLATTENS THE RIDGE IN PLACE. THIS
INCREASE IN WINDS ALOFT ALONG WITH SUBSIDENCE BEHIND COLD FRONT
WILL BRING STRONG WINDS TO MUCH OF THE AREA TODAY. ISSUE IS HOW
STRONG AND WHETHER HIGHLIGHTS ARE NEEDED. HAVE OPTED TO GIVE
WHEATLAND COUNTY A HIGH WIND WARNING BEGINNING LATE MORNING. THIS
DUE TO 50-60KT 700MB FLOW AND EARLIER ONSET OF SUBSIDENCE/COLD
ADVECTION IN THIS AREA...AND FACT THAT WEST WINDS ARE FAVORED IN
THE LEE OF THE BELT AND CRAZY MTNS. GETS TRICKIER FURTHER EAST.
LOCAL TOPOGRAPHY USUALLY RESULTS IN LESS MIXED WIND IN GOLDEN
VALLEY AND MUSSELSHELL COUNTIES. POTENTIAL FOR HIGH WIND IN
NORTHEAST PARTS EMERGES LATE THIS AFTN AND EVNG. COUPLE THINGS
AGAINST IT THOUGH. FIRST IS THAT 40KT 850MB FLOW DOES NOT DEVELOP
UNTIL AFTER 00Z...PER THE NAM. SECOND IS ORIENTATION OF
ISALLOBARIC WIND WHICH WILL BE MORE N-NWLY AND NOT ALIGNED WITH
THE MIXED WEST WINDS. GIVEN THE BORDERLINE NATURE OF THIS EVENT IN
OUR NE WILL PUSH WINDS TO JUST UNDER HIGH WIND CRITERIA...SHOULD
SEE SUSTAINED 35 MPH AND GUSTS 50 MPH THIS AFTN AND EVNG...AND
WILL CONTINUE TO HIGHLIGHT IN THE HWO. DAY SHIFT WILL NEED TO KEEP
WATCH OF HOW THIS EVOLVES. WINDS WILL BE LESS FURTHER SOUTH. AS
FOR THE GAP WINDS...ADVISORY SPEEDS CONTINUE AT LVM AS OF 09Z.
WILL MAKE NO CHANGES TO CURRENT ADVY FOR LVM/NYE AREAS WHICH RUN
THROUGH 15Z. AROUND THAT TIME ONSET OF COLD ADVECTION WILL BRING
THE GAP FLOW TO AN END.

OTHERWISE SYSTEM MOVING THROUGH OUR AREA TODAY IS NOT OVERLY MOIST
OR UNSTABLE. COUPLED WITH STRONG DOWNSLOPE FLOW PLAINS SHOULD BE
MOSTLY DRY AND HAVE REMOVED/LOWERED POPS THIS MORNING AND ACROSS
OUR NORTH THIS AFTN. BEST CHANCE OF PCPN WILL OBVIOUSLY BE OVER
OUR OROGRAPHICALLY FAVORED MTNS WHERE A FEW INCHES OF SNOW SHOULD
FALL THROUGH THIS EVNG. WILL KEEP ISOLD TO SCT POPS ACROSS OUR
SOUTH THIS AFTN AND EVNG AS WINDS TURN NW-N AND MEAGER AFTN
INSTABILITY IS ACHIEVED ALONG FRONTAL PASSAGE. CONDITIONS WILL DRY
OUT FROM NORTH TO SOUTH TONIGHT AS BAROCLINIC ZONE SHIFTS SOUTH
AND SOME VERY DRY AIR ADVECTS IN FROM THE NW. HAVE TRENDED POPS
DOWN TONIGHT...AND WILL BE DRY EVERYWHERE EXCEPT OUR SOUTHERN MTNS
ON TUE AS WE WILL BE UNDER RIDGING AND DRY/STABLE AIRMASS. CHANCES
OF PCPN BEGIN TO INCREASE TUE NIGHT FROM THE SW AS WARM ADVECTION
KICKS BACK IN...THOUGH BASED ON MODEL TRENDS HAVE PUSHED POPS
FURTHER WEST AND SOUTH.

AS FOR TEMPS...DESPITE ONSET OF COLD ADVECTION...WELL-MIXED
BOUNDARY LAYER ALONG WITH SOME FILTERED SUN WILL YIELD A MILD
DAY...ESPECIALLY IN S/SE PARTS WHERE EVEN A FEW HOURS OF PRE-
FRONTAL WARMING MAY BRING TEMPS NEAR 60F. HAVE RAISED EXPECTED
HIGHS SEVERAL DEGREES FROM BILLINGS SOUTH AND EASTWARD. WILL BE
COOLER TUE WITH 850MB TEMPS NEAR OR SLIGHTLY BELOW ZERO. WITH GOOD
MIXING ONCE AGAIN WILL STILL SEE HIGHS AROUND NORMAL.

JKL

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

ACTIVE WEATHER PATTERN SETTING UP FOR WEDNESDAY THROUGH FRIDAY AS
A SERIES OF DISTURBANCES MOVE ACROSS THE FORECAST AREA UNDER A
BLOCKING PATTERN OVER NORTHERN CANADA. MODELS ARE STRUGGLING WITH
TIMING OF THESE WAVES AND HAVE MADE SOME ADJUSTMENTS FOR WEDNESDAY
THROUGH FRIDAY.

ALL 00Z MODEL RUNS HAVE SLOWED DOWN THE SYSTEM FOR WEDNESDAY
WHICH IS A BIG CHANGE FROM THE 18Z RUNS. HAVE TAPERED POPS DOWN
OVER THE CENTRAL AND EASTERN PLAINS BUT LEFT CATEGORICAL POPS
GOING FOR THE SOUTHWEST MOUNTAINS. UNSTABLE SOUTHWEST FLOW
DEVELOPING OVER THE MOUNTAINS WITH ENERGY MOVING IN FROM UPPER
WEST COAST TROUGH ADVANCING TOWARD MONTANA. MODELS BRING UPPER
WAVE THROUGH LATE WEDNESDAY INTO THURSDAY. GFS/NAM/ECMWF
CONSISTENT WITH QPF AMOUNTS AND LOCATION. MODELS SHOWING AN AREA
OF STRONG SURFACE CONVERGENCE SETTING UP ACROSS THE CENTRAL ZONES
ALONG INVERTED SURFACE TROUGH. AMOUNT OF UPPER FORCING AND STEEP
LAPSE RATES INDICATE POTENTIAL FOR POSSIBLE GOOD SNOW EVENT.
HOWEVER...CONFIDENCE IS LOW WITH MODELS BOUNCING AROUND AND WILL
NOT MAKE ANY WHOLE SALE CHANGES IT THIS TIME. DID RAISE POPS FOR
THURSDAY OVER THE ENTIRE AREA AND ALSO FOR THE EASTERN ZONES ON
FRIDAY WITH ENERGY LINGERING OVER THIS AREA. UNSETTLED FLOW TO
CONTINUE OVER THE WEEKEND AND INTO THE FIRST PART OF NEXT WEEK.

FOR TEMPERATURES...DID LOWER THEM A FEW DEGREES WEDNESDAY THROUGH
FRIDAY WITH THE COOLEST DAY ON THURSDAY. RICHMOND

&&

.AVIATION...

STRONG WINDS WILL CONTINUE THROUGH MID MORNING FOR THE UPPER
YELLOWSTONE AND UPPER STILLWATER VALLEYS. SUSTAINED WINDS OF 40
MPH WITH GUST TO 60 MPH CAN BE EXPECTED THROUGH 10 AM. THESE
WINDS WILL DECREASE AS A COLD FRONT MOVES THROUGH. STRONG WINDS
WILL DEVELOP FROM KBIL TO KBHK...AND FROM KBIL SOUTH TO KSHR LATE
THIS MORNING. THESE WINDS WILL CONTINUE THROUGH EARLY EVENING.
WIND SPEEDS OF 25 TO 40 MPH CAN BE EXPECTED. VFR CONDITIONS WILL
PREVAIL THROUGH THE DAY OVER THE PLAINS. MOUNTAIN OBSCURATIONS
WILL DEVELOP EARLY THIS AFTERNOON WITH MOUNTAIN SNOW SHOWERS.
