AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
327 PM MST FRI FEB 24 2012

.SHORT TERM...VALID FOR SAT AND SUN...

A PROGRESSIVE AND FAST CHANGING WEATHER PATTERN WILL BE THE THEME
THE NEXT FEW DAYS ACROSS OUR REGION.

THERE REMAINS QUITE A BIT OF INSTABILITY ACROSS OUR EASTERN ZONES
IN THE NW FLOW ALOFT. AS SUCH...I EXPECT A FEW LINGERING SNOW
SHOWERS OR FLURRIES THIS EVENING OVER THE EASTERN ZONES BEFORE
SUBSIDENCE FROM A BUILDING RIDGE OF HIGH PRESSURE TAKES OVER. FOR
THE WEEKEND...SHORT TERM MODELS IN IN FAIR AGREEMENT WITH AVERAGE
TO SOMEWHAT ABOVE AVERAGE CONFIDENCE. THE MAIN ISSUE I AM
CONCERNED WITH WILL BE WIND POTENTIAL.

WIND POTENTIAL...AS HIGH PRESSURE BUILDS OVER OUR REGION...LEE SIDE
TROUGHING IS PROGGED TO OCCUR TONIGHT OVER THE PLAINS. THIS WILL
LEAD TO A STRONG PRESSURE GRADIENT DEVELOPING OVER OUR WESTERN
ZONES WITH A SOUTHERLY ORIENTATION WHICH IS FAVORABLE FOR OUR
NORTH TO SOUTH ORIENTED VALLEYS. CROSS SECTIONS INDICATE A
MODERATELY STABLE LAYER AT MOUNTAIN TOP LEVEL AS WELL. THIS SHOULD
SET THE STAGE FOR GAP FLOW LATER TONIGHT INTO SATURDAY MORNING
OVER THE BEARTOOTH FOOTHILLS AND LIVINGSTON AREAS. NOW WE DO HAVE
A COLD FRONT COMING THROUGH ASSOCIATED WITH AN UPPER LEVEL TROUGH.
THIS WILL ERODE THE STABLE LAYER AND TRANSITION THE EVENT OVER THE
FOOTHILLS AND LIVINGSTON TO A MIX DOWN OF STRONG WINDS RATHER
THAN GAP FLOW SATURDAY THROUGH SATURDAY EVENING. THUS...WILL
ISSUE A WIND ADVISORY FOR THE GAP FLOW AREAS FROM 9 PM TONIGHT TO
MIDNIGHT SUNDAY MORNING. WE MAY NEED TO ADD THE BIG TIMBER TO THIS
ADVISORY FOR SATURDAY AFTERNOON...BUT UNCERTAINTY LOOMS A BIT ON
THIS YET SO WILL LET NEXT FEW SHIFTS MONITOR THE POTNETIAL THERE.

THE COLD ADVECTION LATE SATURDAY THROUGH MUCH OF SATURDAY NIGHT
ALONG WITH STEEP LOW LEVEL LAPSE RATES SHOULD PRODUCE STRONG WINDS
OVER THE EASTERN PLAINS AS WELL. HOWEVER...850MB WINDS ARE BELOW
50 MPH SO WHILE WE MAY SEE AN ISOLATED GUST TO NEAR 60 MPH OVER
THE PLAINS WITH A SHOWER...I EXPECT WINDS TO GENERALLY REMAIN
BELOW OUR HIGH WIND CRITERIA. STILL..LOOK FOR BLUSTERY WEST TO
NORTHWEST WINDS ACROSS BILLINGS AND THE PLAINS LATE SATURDAY INTO
SATURDAY NIGHT WITH GUSTS TO 50 MPH LIKELY. THIS SHOULD KEEP
OVERNIGHT LOWS UP SOME DESPITE COLD ADVECTION.

NOW FOR PRECIPITATION POTENTIAL...AS PREVIOUSLY MENTIONED WITH
THE RIDGE BUILDING OVER THE REGION TONIGHT MOST IF NOT ALL OF THE
SCATTERED SNOW SHOWERS SHOULD END. WE DO HAVE SOME WEAK
ISENTROPIC LIFT SATURDAY AHEAD OF THE APPROACHING TROUGH...BUT
THE MOISTURE AND LIFT ARE RATHER HIGH SO WILL PROBABLY NOT AMOUNT
TO MORE THAN SOME SPRINKLES OR FLURRIES SATURDAY MORNING...MAINLY
ON THE EAST SIDE OF THE SURFACE TROUGH. HOWEVER...BY SATURDAY
AFTERNOON A VIGOROUS TROUGH WILL TRACK RIGHT OVER THE REGION.
PROGGS INDICATE PLENTY OF Q VECTOR FORCING ASSOCIATED WITH THIS
FEATURE. POTENTIAL TEMPERATURE PROFILES IN THE CROSS SECTIONS
OVER OUR REGION SHOW DEEP INSTABILITY. HOWEVER...STRONG WESTERLY
FLOW AND SUBSIDENCE WITH THIS SYSTEM WILL LEAD TO DOWNSLOPE AND
DECENT DOWNWARD MOTION AS FAR EAST OF THE MOUNTAINS AS
BILLINGS...AND AT THAT POINT THE LIFT AND INSTABILITY SHOULD WIN
OUT. SO WILL BUMP UP POPS IN THE EAST SATURDAY AFTERNOON AND KEEP
THEM SOMEWHAT LOW FROM BILLINGS TO THE FOOTHILLS.

CONDITIONS REMAIN UNSETTLED SATURDAY NIGHT AS UNSTABLE FLOW ON THE
BACKSIDE OF THE TROUGH CONTINUES TO PRODUCE WIND AND SCATTERED
SNOW SHOWERS. A RIDGE OF HIGH PRESSURE WILL BUILD INTO THE ROCKIES
SUNDAY WITH A BRIEF LULL IN MOST OF THE PRECIPITATION. HOWEVER...THE
EXITING UPPER TROUGH TO THE EAST WILL PULL DOWN SOME COLD
CANADIAN AIR WHICH SHOULD ROLL INTO THE BILLINGS AREA BY LATE
AFTERNOON. LOOK FOR A SWITCH FROM BRISK NW WINDS TO STEADY LIGHT
EAST WINDS LATE SATURDAY WITH TEMPERATURES FALLING. MOISTURE AND
UPSLOPE APPEAR RATHER SHALLOW SO WILL KEEP POPS ON THE LOW
SIDE...THOUGH AT LEAST FLURRIES SEEM LOGICAL GIVEN SOME
OVERRUNNING AND EASTERLY FLOW BY SUNDAY EVENING. BT

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

AN INTERESTING WEATHER SCENARIO IS DEVELOPING FOR EARLY NEXT
WEEK. MODELS HAVE BEEN CONSISTENT IN PHASING A VORTICITY MAXIMUM
DROPPING OUT OF CANADA ON MONDAY WITH A FAST MOVING VORTICITY
MAXIMUM COMING OFF THE PACIFIC OCEAN. THE PHASING ALLOWS THE
DEVELOPMENT OF A DIGGING TROUGH THAT SLOWS DOWN AND CUTS OFF
ACROSS THE WESTERN CONUS. THE SLOW MOVING UPPER LEVEL LOW HELPS
THE SYSTEM TAP INTO SUBTROPICAL MOISTURE AND OPENS UP A MOISTURE
FEED FROM THE GULF OF MEXICO. THE MODELS AGREE ON DEVELOPING A
700 MB LOW IN WYOMING WITH A SURFACE LOW DEVELOPING IN WESTERN
NEBRASKA. HOWEVER...THE EXACT TRACK OF THIS LOW IS CERTAIN...AND
WILL BE CRITICAL IN DETERMINING THE SENSIBLE WEATHER ACROSS
MONTANA. LATEST MODEL TRENDS HAVE BEEN FOR THE LOW TO BE SLIGHTLY
STRONGER AND FURTHER NORTH...WHICH IS FAVORABLE FOR GETTING SNOW
ACROSS SOUTHEAST MONTANA AND EVEN INTO SOUTH CENTRAL MONTANA.
CURRENT THINKING IS THAT THIS LOW WILL TRACK IN A FAVORABLE ENOUGH
LOCATION TO GET STRONG INSENTROPIC LIFT OF THE MOIST SUBTROPICAL
AIR ACROSS SOUTHEASTERN MONTANA. THIS COULD BRING SIGNIFICANT
SNOWFALL AS 850 TEMPERATURES WILL REMAIN COLD... -8 TO -10 C
...BEHIND THE WEEKENDS STORM SYSTEM. TO HELP GET THE WORD OUT ON
THE POTENTIAL FOR THIS STORM HAVE INCREASED POPS TO 50 ACROSS
EASTERN MONTANA WITH 30 POPS REACHING INTO BILLINGS. WILL HAVE TO
CONTINUE TO MONITOR THE MODEL TRENDS WITH THIS STORM AS IT QUITE
POSSIBLE THAT WE ARE UNDERFORECASTING THE WEST REACHING EXTENT OF
THIS SYSTEM. HAVE ALSO LOWERED HIGH TEMPERATURES FOR TUESDAY AND
WEDNESDAY...ESPECIALLY ACROSS THE EAST...AS THE SHIFT IN THE TRACK
OF THE LOW AND ITS INTENSITY WILL BRING STRONG COLD ADVECTION
ACROSS THE EASTERN COUNTIES ON WEDNESDAY...NOT TO MENTION THE
POTENTIAL SNOW PACK REMAINING BEHIND THE STORM.

AS THE UPPER LEVEL LOW EXITS THE REGION ON WEDNESDAY...THERE WILL
BE A BRIEF PERIOD OF WARMING AND DRYING OUT ACROSS THE REGION.
HOWEVER...MODELS AGREE ON RETURNING TO A PROGRESSIVE AND MOIST
NORTHWESTERLY FLOW. THE PATTERN APPEARS FAVORABLE FOR MOUNTAIN
SNOW SHOWERS AND DOWNSLOPE AND WINDY FLOW ACROSS THE PLAINS FOR
THURSDAY INTO FRIDAY. WHILE THE WEATHER LOOKS FAIRLY MESSY THROUGH
THIS PERIOD...EXPECT TEMPERATURES TO BE MILD FOR THE END OF THE
WEEK. CHURCH

&&

.AVIATION...

MOSTLY VFR CONDITIONS ARE EXPECTED ACROSS THE REGION TONIGHT. THE
ONE EXCEPTION WILL BE ACROSS FAR EASTERN MONTANA...NEAR
KBHK...WHERE INTERMITTENT MVFR CONDITIONS IN LOW CLOUDS AND SNOW
SHOWERS WILL OCCUR FOR THE NEXT FEW HOURS. SOUTHWEST WINDS WILL
INCREASE IN THE KLVM REGION LATE THIS EVENING WITH GUSTS TO 50-55
KTS LIKELY BETWEEN 08Z AND 15Z. A STRONG COLD FRONT WILL MOVE
THROUGH THE REGION DURING THE DAY SATURDAY...BRINGING RAIN AND
SNOW SHOWERS TO THE REGION AS WELL AS WIND GUSTS IN THE 40-45 KT
RANGE AS FAR EAST AS A HYSHAM TO SHERIDAN LINE. MOUNTAIN
OBSCURATIONS WILL INCREASE LATE TONIGHT INTO EARLY SATURDAY AS
SNOW CHANCES INCREASE. STC
