AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
302 AM PST THU DEC 14 2006

.SYNOPSIS...GUSTY WINDS WILL DIMINISH OVER THE REGION FOR THE
REMAINDER OF THE EVENING AS A POWERFUL STORM SYSTEM EXITS THE
REGION. ANOTHER STRONGER STORM WILL TRACK THROUGH THE REGION LATE
THURSDAY NIGHT AND FRIDAY. POTENTIALLY DAMAGING WINDS AND
SIGNIFICANT AMOUNTS OF PRECIPITATION ARE EXPECTED TO ACCOMPANY
THIS STORM.

&&

.DISCUSSION...
TODAY AND TONIGHT...THE SECOND OF A PAIR OF STRONG STORM SYSTEM
WILL MOVE INTO THE REGION THIS AFTERNOON AND LAST THROUGH FRIDAY.
THE MODELS ARE IN GENERAL AGREEMENT OF THE TIMING AND TRACK OF THE
SURFACE LOW CURRENTLY OUT NEAR 135W. THE SURFACE IS LOW IS
EXPECTED TO TRACK FROM ITS CURRENT POSITION NORTHEAST THROUGH
VANCOUVER ISLAND BETWEEN 00-06Z THIS EVENING AND INTO ALBERTA BY
18Z FRIDAY. THIS IS A SIGNIFICANT STORM...NOT NECESSARILY FROM A
RAIN/SNOW AMOUNT BUT FOR WINDS. A WARM FRONT IS CURRENTLY MOVING
INTO WESTERN OREGON AND WILL SLOWLY MOVE NORTHEAST INTO THE
WASHINGTON BASIN BY MID MORNING AND CONTINUE ACROSS THE FORECAST
AREA THROUGH THE DAY. MODEL STRENGTH WITH THE ISENTROPIC LIFT IS
A CONCERN THROUGH THE SHORT TERM PERIOD. THE NAM IS QUITE A BIT
LESS IMPRESSIVE THAN THE GFS SOLUTION AND WENT AHEAD AND LEANED
TOWARDS THE GFS. SATELLITE LOOP SHOWING A CONTINUATION OF A GOOD
MOISTURE TAP POINTED RIGHT AT THE PACIFIC NORTHWEST RIDING A 150+
KT JET. AS SUCH EXPECT ANOTHER PRETTY WET SYSTEM. THE CHALLENGE
AGAIN IS PRECIPITATION TYPE AND SNOW LEVELS. CLEAR SKIES AND LIGHT
WINDS OVER NIGHT HAVE ALLOWED GOOD RADIATIONAL COOLING DROPPING
THE SNOW LEVELS BETWEEN 2500-3500 FEET. EXPECT PRECIPITATION
MAINLY AS RAIN FOR THE LOWER ELEVATIONS. ACROSS THE NORTHEAST
MOUNTAINS AND IDAHO PANHANDLE MOUNTAINS PRECIPITATION AS
SNOW. BUT HERE IS WHERE IT GETS INTERESTING WITH STRONG...SOUTHWEST-
WEST FLOW AND WARM AIR ADVECTION SNOW LEVELS SHOULD BEGIN TO START
CLIMBING THIS EVENING WHEN WE GET OUR BEST QPF AMOUNTS. RIGHT NOW
SNOW AMOUNTS ABOVE 4000 FEET ARE ENOUGH TO SUPPORT WINTER HIGHLIGHTS
AND WILL UPGRADE THE WATCH TO A WINTER STORM WARNING FOR BOTH SNOW
AMOUNTS AND STRONG WINDS...I ALSO WENT AHEAD AND ADDED WAZ037 TO THE
WARNING. THIS WILL HAVE TO BE MONITORED FOR SNOW LEVELS TODAY. THE
BIGGEST THREAT FROM THIS STORM WILL BE THE FROM THE WINDS. A 50-60
KT LOW LEVEL (85H) JET COUPLED WITH A TIGHTENING SOUTHWEST SURFACE
GRADIENT AND MIXING TO THE SURFACE WITH THE COLD FRONT PASSAGE THIS
EVENING...IT APPEARS AS IF EVERYTHING IS LINING UP FOR WINDS
TO REACH HIGH WIND CRITERIA. WITH GUSTY WINDS AND STRONG WARM AIR
ADVECTION TEMPERATURES ACROSS THE LOWER ELEVATIONS WILL AGAIN BE 5+
DEGREES ABOVE NORMAL. /TOBIN

FRI THROUGH WED...FCST FOCUS CONTINUES TO BE ON WINDS FOR THURS NT
AND FRI. THE TRACK OF THE STRONG 975MB CYCLONE LATE THURS NT AND
FRI REMAINS NE...TAKING IT ACROSS VANCOUVER ISLAND BY 12Z FRI...THEN
FILLING AND REACHING ALBERTA DURING THE DAY. CLOSE TO THE TIME OF
COLD FROPA...THE COLUMBIA BASIN/ PALOUSE LOW-LEVEL TERRAIN-ENHANCED
JET DEVELOPS VERY RAPIDLY...PEAKING AROUND 12Z FRI WITH 850MB WINDS
WITHIN THE CORE OF THE JET AS HIGH AS 70 KTS. PATTERN RECOGNITION AND
RECENT SIMILAR STORMS CLEARLY SHOW A DAMAGING WIND THREAT FOR LATE
THURS NT AND FRI MORNING BEFORE THE CYCLONE RAPIDLY WEAKENS AND
MOVES ACROSS THE CONTINENTAL DIVIDE AND INTO THE CANADIAN HIGH
PRAIRIES BY LATE FRI. THE BIG FCST CHALLENGE WILL BE TRYING TO
DETERMINE THE DEGREE OF MIXING AND SUBSEQUENT COUPLING OF NR-SFC
WINDS WITH THOSE ALOFT. FROM THE PALOUSE AND N INTO SPOKANE AND
THE NE MTNS/ ID PANHANDLE...IT APPEARS THAT MIXING CERTAINLY WONT
BE AN ISSUE...EVEN INITIALLY...WITH A STRAIGHT-FORWARD WIND FCST.
THIS REGION WILL SEE VERY STRONG WINDS FRI MORNING...SUSTAINED AT
40 MPH WITH GUSTS AS HIGH AS 60 MPH. A HIGH WIND WARNING HAS BEEN
ISSUED. TO THE W...ITS A BIT TRICKIER FCST. DEEP IN THE COLUMBIA
BASIN...FCST GUIDANCE KEEP THE STRONGEST WINDS FROM PENETRATING
WHATS LEFT OF ANY SFC-BASED INVERSIONS FRI MORNING...KEEPING THE
WINDS WELL BELOW WARNING THRESHOLDS. WITH THE MAGNITUDE OF THE
CAA...AND ONLY 10-15 DEGREES OF VEERING FROM THE SFC TO THE
STRONG WINDS ALOFT...ANY DELAY OF THE ONSET OF THE STRONGER WINDS
SHOULD ONLY BE A COUPLE HRS. RECENT MOS GUIDANCE HAS DONE FAIRLY
WELL IN DISTINGUISHING WHICH SITES IN THESE LOWER BASIN
TOWNS...INCLUDING KEAT...MIX AND GET THE STRONGER WINDS FROM ALOFT
DOWN TO THE SFC VERSUS THE SITES THAT REMAIN DECOUPLED AND OUT OF
THE STRONG WIND THREAT. GUIDANCE KEEPS KMWH AND KEAT DECOUPLED...
BUT FULLY MIXES KMWH AND KEPH BY 15Z FRI. FOR THIS REASON...WEVE
KEPT THE HIGH WIND WATCH UNCHANGED FOR THE KMWH REGION...BUT HAVE
UPGRADED THE WATCH TO A HIGH WIND WARNING ACROSS MUCH OF THE REST
OF ERN WA AND THE MTNS OF N ID. NO CHANGES TO THE REST OF THE
MEDIUM AND EXTENDED-RANGE FCST. BZ

&&

.AVIATION...AS A PACIFIC STORM SYSTEM EXITS THE REGION CONTINUING
MOUNTAIN OBSCURATIONS IN CLOUDS AND SNOW WILL REMAIN THROUGH 12Z
THURSDAY OVER THE IDAHO PANHANDLE. MAINLY VFR CONDITIONS WILL
PREVAIL OVER THE BASIN THROUGH 18Z THURSDAY. ANOTHER POWERFUL
STORM SYSTEM WILL SPREAD A WARM FRONT WITH MAINLY MVFR CEILINGS WITH
LOCAL IFR CEILINGS AND VISIBILITY IN SNOW AND RAIN FROM SOUTH TO
NORTH AFTER 18Z THURSDAY. STRONG WINDS WITH LLWS OVER EASTERN TAF
SITES WILL BECOME DOMINANT AFTER 00Z FRIDAY. /MJF
