AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BILLINGS MT
925 PM MST WED JAN 14 2015

.UPDATE...

FORECAST IS IN GOOD SHAPE AND HAVE ONLY MADE A MINOR ADJUSTMENT
TO TEMPERATURES. ANOTHER QUIET EVENING ACROSS THE FORECAST AREA.
TEMPERATURES ARE A BIT WARMER THAN LAST EVENING AS A RESULT OF A
WARMER AFTERNOON AND SOME WINDS THIS EVENING. SATELLITE AND
OBSERVATIONS CURRENTLY SHOW MOSTLY CLEAR SKIES ACROSS THE FORECAST
AREA. HOWEVER...A NORTHWEST FLOW ALOFT IS BRINGING SOME CLOUDS
SOUTHEAST OUT OF CANADA AND THESE ARE EXPECTED TO MOVE ACROSS THE
FORECAST AREA FOR THE REMAINDER OF THIS EVENING AND THROUGH THE
OVERNIGHT HOURS BRINGING SOME PARTLY CLOUDY SKIES TO THE AREA.
WINDS ARE NOT STRONG ACROSS THE WESTERN AREAS BUT REMAIN IN THE 15
TO 25 MPH RANGE FOR BIG TIMBER...LIVINGSTON AND THE
BEARTOOTH/ABSAROKA FOOTHILLS. TEMPERATURES FOR THOSE LOCATIONS
REMAIN IN THE LOWER 30S...ABOVE FORECASTED LOWS. GIVEN THAT WINDS
WILL CONTINUE THROUGHOUT THE NIGHT...TEMPERATURES ARE NOT EXPECTED
TO DROP OFF MUCH OR AT ALL...AND AS A RESULT...RAISED OVERNIGHT
LOWS FOR THESE AREAS SEVERAL DEGREES...BASICALLY TO THEIR CURRENT
READINGS. UPDATED FORECAST HAS BEEN SENT. HOOLEY

&&

.SHORT TERM...VALID FOR THU AND FRI...

WINDS HAVE BACKED OFF OVER WESTERN LOCATIONS WITH GUSTS NOW DOWN
TO 38 MPH AT HARLOWTON AND BELOW 20 MPH AT LIVINGSTON AND BIG
TIMBER. WINDS SHOULD INCREASE AGAIN TONIGHT AS HIGH PRESSURE
STRENGTHENS IN THE IDAHO VALLEYS. NOT EXPECTING AS MUCH DRAINAGE
INFLUENCE DUE TO SLIGHT WARMING OVER THE NORTHERN ROCKIES.
MOUNTAIN TOP LEVEL STILL LOOKS RATHER STABLE...SO WILL BE ABLE TO
SQUEEZE STRONGER WINDS THROUGH EAST TO WEST ORIENTATED GAPS...BUT
NOT EXPECTING WINDS AS STRONG AS LAST NIGHT. DID BUMP WINDS HIGHER
THOUGH AND BRIEFED THE EVENING CREW TO KEEP A CLOSE EYE ON THINGS.

WINDS WILL BECOME QUITE STRONG THURSDAY NIGHT WITH A DEEP LEE
TROUGH FORMING. THIS WILL BE THE MOST LIKELY PERIOD OF POTENTIAL
HIGHLIGHTS FOR LIVINGSTON...NYE AND BIG TIMBER. WINDS WILL STAY
STRONG THROUGH FRIDAY. GRADIENT TURNS MORE FAVORABLE FOR BIG
TIMBER AND HARLOWTON FRIDAY AND FRIDAY NIGHT. BUMPED WINDS UP FOR
THESE PERIODS. A PIECE OF FAST MOVING ENERGY SLICES ACROSS THE
SOUTHWEST MOUNTAINS THURSDAY EVENING...SO INCLUDED SOME LOW POPS.

THE STRONGER WINDS WILL PUSH OUT ONTO THE PLAINS FRIDAY NIGHT.
850MB WINDS INCREASE TO 50 KTS OVER CENTRAL AND EASTERN ZONES.
SHORTWAVE ACTIVITY MOVES THROUGH FRIDAY NIGHT FOR ASCENT THAT WILL
KEEP THOSE STRONGER WINDS ALOFT...BUT BEHIND THE WAVE...SOME
SUBSIDENCE KICKS IN FOR A BRIEF SHOT OF POTENTIAL WIND. COULD BE
BIG WINDS LATE FRIDAY NIGHT OVER THE EASTERN HALF OF THE FORECAST
AREA. WILL BE TRICKY AS ANOTHER FAST MOVING SHORTWAVE FOLLOWS THE
INITIAL WAVE LATE FRIDAY NIGHT. THIS MAY COUNTERACT THE SUBSIDENCE
PERIOD AND LIMIT THE MIXING POTENTIAL DURING THIS TIME. BUMPED
WINDS UP FOR THIS PERIOD AND WILL HAVE TO SEE HOW FUTURE MODEL
RUNS HANDLE THINGS. TEMPERATURES WILL BE WARMER WITH DOWNSLOPE
FLOW. SNOW COVER WILL DECREASE OVER TIME WHICH WILL INCREASE RUN
OFF. THE SNOW COVER WILL LIMIT HEATING OF THE DAY POTENTIAL...SO
KEPT HIGHS SLIGHTLY BELOW GUIDANCE. TWH

.LONG TERM...VALID FOR SAT...SUN...MON...TUE...WED...

MILD AND WINDY WEATHER THIS WEEKEND WILL TRANSITION TO A COOLER
AND UNSETTLED WEATHER PATTERN NEXT WEEK AS ZONAL FLOW ALOFT TURNS
TO THE NORTH-NORTHWEST. THAT SHIFT WILL BE DRIVEN BY A SHORTWAVE
TROUGH PASSAGE CENTERED ON MONDAY IN BOTH THE 12 UTC GFS AND ECMWF
SIMULATIONS. WARM AIR ADVECTION WILL BE ONGOING THIS WEEKEND OUT
AHEAD OF THAT WAVE...AND BY SUNDAY AFTERNOON 850-MB TEMPERATURES
OF +6 TO +9 C COULD SUPPORT HIGHS IN THE 50S F IF THE SNOW FIELD
HAS MELTED CONSIDERABLY BY THAT POINT /WHICH IS FAR FROM CERTAIN/.
THE GREATEST IMPACT IN THE LONG TERM WILL LIKELY BE STRONG WINDS
IN THE FOOTHILLS SATURDAY NIGHT AND SUNDAY WHEN LEE-SIDE PRESSURE
FALLS COMMENCE WITH 700-MB WINDS OF 50+ KT SHOWN BY THE 12 UTC GFS
AND ECMWF. THIS SCENARIO WILL LIKELY PRODUCE ADVISORY-LEVEL GUSTS
OF 60+ MPH IN LIVINGSTON...NYE AND POSSIBLY BIG TIMBER.

COLD AIR ADVECTION BEGINNING MONDAY SHOULD COOL TEMPERATURES BACK
DOWN TOWARD NORMAL WITH HIGHS IN THE 30S F EARLY NEXT WEEK BASED
ON THE 12 UTC MULTI-MODEL CONSENSUS. THERE WILL BE SOME CHANCE OF
SNOW SHOWERS WITH THE SHORTWAVE TROUGH PASSAGE AND THE NORTHWEST
FLOW ALOFT IN ITS WAKE...BUT THE PATTERN SHOULD NOT SUPPORT ANY
SNOWFALL OF REAL SIGNIFICANCE AT THE LOWER ELEVATIONS. SCHULTZ

&&

.AVIATION...

VFR CONDITIONS WILL CONTINUE TONIGHT AND THURSDAY WITH ONLY SOME
PASSING HIGH-LEVEL CLOUDS. GUSTY WINDS WILL ALSO CONTINUE ACROSS
SOUTH CENTRAL MT IN AND AROUND THE FOOTHILLS WITH GUSTS TO AROUND
40 KT AT KLVM...K6SO AND K3HT. SCHULTZ
