AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
250 PM PST FRI DEC 21 2007

.SYNOPSIS...
EXPECT A RETURN TO AN ACTIVE STORM CYCLE AS THE WEATHER ONCE
AGAIN DEGENERATES THIS WEEKEND. A SERIES OF SYSTEMS ARE EXPECTED
TO MOVE THROUGH THE AREA THROUGH NEXT WEEK.

&&

.DISCUSSION...
TONIGHT THROUGH SATURDAY NIGHT...INFRARED SATELLITE SHOWS A WELL
DEVELOPED CYCLONE NEAR 50N/140W MOVING TOWARDS CENTRAL BRITISH
COLUMBIA. THE TRAILING FRONTAL BOUNDARY ASSOCIATED WITH THIS
SYSTEM IS WHAT WILL CROSS THE CASCADES INTO EASTERN WA/IDAHO ON
SATURDAY. SATELLITE DERIVED PRECIPITABLE WATERS WITHIN THE FRONTAL
BOUNDARY RANGE FROM 1-1.5 INCHES. GFS SOLUTION HAS SUPPORT FROM
ECMWF/UKMET/CANADIAN MODELS SO GFS WAS FOLLOWED...WHICH SHOWS THIS
FRONT QUICKLY MOVING THROUGH THE AREA.

AS THE WARM AND MOIST PACIFIC SYSTEM OVERRIDES THE COLD AIR THAT
MOVED INTO THE AREA LAST NIGHT AND THIS MORNING...ISENTROPIC LIFT
WILL INCREASE. TIMING OF INCREASING LIFT AND DEVELOPMENT OF PRECIP
LOOKS TO BEGIN NEAR THE CASCADES AROUND 4 AM PER GFS ALTHOUGH
LIGHT SNOW MAY DEVELOP SLIGHTLY BEFORE THIS...SPREADING EAST
ACROSS EASTERN WA/ID LATE MORNING. PRECIP TYPE PER 1000-850MB
THICKNESSES AT OR BELOW 1300DM SUGGEST SNOW...EXCEPT FOR THE
LEWISTON AREA WHERE DOWNSLOPE FLOW OFF THE BLUE MTNS RESULTS IN
SLIGHTLY WARMER LOW LEVEL TEMPS. THIS DOWNSLOPE WILL ALSO REDUCE
PRECIP CHANCES HERE. GOING WITH GFS MODEL QPF AMOUNTS AND A 13:1
SNOW AMT:QPF RATIO YIELDS ACCUMULATIONS ACROSS MOST VALLEY AREAS
RANGING FROM 1 TO 3 INCHES...WITH THE HIGHER ACCUMULATIONS WITHIN
THIS RANGE OVER N WASHINGTON AND IDAHO WHERE UPSLOPE FLOW SHOULD
ENHANCE SNOW AMOUNTS. HIGHER AMOUNTS ARE ALSO LIKELY ALONG THE
EAST SLOPES OF THE WA CASCADES WITH S-SSE UPSLOPE FLOW FROM THE
SFC- 850MB. WHILE THIS DIRECTION IS NOT IDEAL FOR BEST
UPSLOPE...IT SHOULD BE ENOUGH TO REDUCE SHADOWING OFF THE CASCADES.
SEVERAL OTHER AREAS ARE FLIRTING WITH ADVISORY CRITERIA WITH NEAR
2 INCHES OF ACCUMULATION...BUT CONFIDENCE IS NOT AS HIGH ELSEWHERE
SO WILL LET EVE/MID SHIFT EVALUATE FURTHER. PLEASE SEE BOTTOM OF
DISCUSSION FOR MORE SPECIFIC DETAILS OF HIGHLIGHTS.

THE COLD FRONT SHOULD CROSS THE CASCADES LATE SATURDAY AFTERNOON
AND INTO IDAHO IN THE EVENING. BEHIND THE COLD FRONT WESTERLY FLOW
OFF THE CASCADES SHOULD BRING A QUICK END TO THE PRECIPITATION IN
THE TYPICALLY RAIN SHADOWED VALLEYS EAST OF THE CASCADES. A BRIEF
PERIOD OF HEAVIER SNOW IS POSSIBLE OVER THE HIGHER TERRAIN OF N
IDAHO AS THE FRONT PASSAGE OCCURS WITH STRONG UPSLOPE FLOW
IMMEDIATELY BEHIND FRONT PASSAGE. THE BOUNDARY LAYER STAYS NEARLY
SATURATED SAT NIGHT BEHIND THE FRONT WHICH WILL LIKELY KEEP A
LARGE AREA OF STRATUS IN PLACE IN THE VALLEYS LIMITING ANY
SIGNIFICANT TEMP FALLS. JW

SUNDAY THROUGH MON...FOCUS WILL BE SNOW LEVELS AND SNOW AMNTS
CENTERED AROUND SUNDAY NIGHT. THIS STORM SHOULD BE STRONGER THAN
THE ONE FOR SAT...BUT A BIT WARMER. THOUGH COLD FROPA WONT BE
UNTIL SUNDAY NIGHT...MUCH OF ERN WA AND N ID WILL HAVE TO CONTEND
WITH THE LEAD WARM-FNT SUNDAY. THIS WARM-FNT WILL SPREAD A
STEADILY INCREASING SWATH OF ISENTROPIC ASCENT FROM W TO E BELOW
ABOUT 700MB SUNDAY...WITH SNOW INCREASING FIRST NEAR THE CASCADES
MIDDAY SUNDAY...THEN INTO NE WA AND N ID LATER SUNDAY. THE FORCING
FOR DEEP ASCENT IS CERTAIN TO BE WELL SUFFICIENT TO PRODUCE A
DECENT AMNT OF PCPN. DETERMINING SNOW LEVELS IS MUCH MORE
CHALLENGING. WE PREFER THE GFS TIMING AND ITS LOW-LEVEL THERMAL
AND WINDS FIELDS LATE SUNDAY AS A SURGING WARM-SECTOR EMBEDDED
WITHIN SLY 850MB WINDS OF 30-35KT RAISES SNOW LEVELS TO ABOVE 2500
FEET OVER MUCH OF THE COLUMBIA BASIN BY SUNDAY EVENING. SNOW
LEVELS WILL REMAIN VERY LOW NEAR THE CASCADES HOWEVER THE ENTIRE
EVENT AS COLD AIR REMAINS CRAMMED AGAIN THE E SLOPES CASCADES AND
SHELTERED FROM THE STRONG 850MB WINDS TO THE E. THE PREVIOUS
VERSION OF THE NAM WAS MUCH COOLER...WITH SNOW LEVELS NOT GOING
ABOVE 2000 FEET ANYWHERE. THE LATEST NAM HAS NOW COME MUCH MORE
IN LINE WITH THE WARMER AND WINDIER GFS. THAT SAID...WINTER STORM
WATCHES WONT BE ISSUED ATTM BUT MAY BE NEEDED FOR ALL ZONES
ADJACENT TO THE BC BORDER. WITH FROPA SUNDAY NT...PCPN WILL END IN
THE BASIN ZONES...BUT RAMP UP FOR THE N ID PANHANDLE AND PALOUSE
SUNDAY NIGHT AND MON AS THE POST-FRONTAL UNSTABLE AIR MASS AND
STRONGLY VEERED W/NWLY FLOW WORKS ITS WAY INTO THE REGION. BZ

MONDAY NIGHT THROUGH FRIDAY...EXTENDED MODEL GUIDANCE AND THE
ENSEMBLE MEANS ARE ACTUALLY IN FAIRLY GOOD AGREEMENT THROUGH THE
BEGINNING OF THIS PERIOD. LOOKS LIKE MONDAYS SYSTEM WILL PUSH INTO
WESTERN MONTANA DURING THE EVENING. THIS WILL LIKELY ALLOW SOME
SHOWERS TO HOLD OVER THE EASTERN THIRD OF THE CWA EARLY BUT THEY
SHOULD TAPER OFF RAPIDLY OVERNIGHT AS A FAIRLY STRONG UPPER LEVEL
RIDGE PUSHES OVER THE CASCADES. THE RIDGE WILL LIKELY KEEP THE
WEATHER FAIRLY BENIGN THROUGH CHRISTMAS MORNING. AFTER THAT...THE
NEXT STORM REACHES THE COAST. THIS ONE WILL LIKELY SPREAD LIGHT
PRECIPITATION ACROSS MUCH OF THE INLAND NW. GIVEN WIDESPREAD 850
MB TEMPS BETWEEN -4 TO -8C...WE SUSPECT ALL OF IT WILL FALL AS
SNOW. THE ENSEMBLES AND GFS SUGGEST THIS SYSTEM WILL SPLIT AS IT
NEARS THE COAST...WITH MUCH OF THE ENERGY PUSHING THROUGH NORTHERN
CALIFORNIA. THE ECMWF SHOWS A LITTLE MORE CONSOLIDATION AND MIGHT
SUPPORT A LITTLE MORE PRECIPITATION...HOWEVER IT LOOKS LIKE THIS
SYSTEM WILL LIKELY PALE COMPARED TO SUNDAY NIGHT AND MONDAYS
STORM. MORE IMPORTANTLY...THE COLD FRONT WHICH IS USHERED INTO THE
REGION BEHIND THIS SYSTEM SHOULD DROP TEMPERATURES MARKEDLY BELOW
FREEZING...AT LEAST THATS WHAT THE 850 MB TEMP PROGS ARE
INDICATING. SINCE THE AMPLIFICATION OF THE 500 MB PATTERN IS NOT
THAT IMPRESSIVE...IT LOOKS LIKE WE WILL BE ADVECTING THIS COOLER
AIRMASS OUT OF NORTHERN BC RATHER THAN THE POTENTIALLY MUCH COLDER
AIRMASS FOUND OVER ALASKA AND THE YUKON. GIVEN THE COOL 850 MB
FORECASTS IT SEEMS SURFACE TEMPS SHOULD BE ABOUT 5-10F BELOW
NORMAL FOR THIS TIME OF YEAR WHICH IS A BIT COOLER THAN THE MOS
NUMBERS.

THE ENSEMBLE MEAN AND ECMWF SUGGEST WE WILL TRANSITION TO A
MOIST ZONAL FLOW PATTERN BY THURSDAY NIGHT AND FRIDAY...WHILE THE
GFS DEVELOPS A POWERFUL UPPER LEVEL LOW OFF THE BC COAST. EITHER
SITUATION WILL LIKELY RESULT IN AN INCREASE IN PRECIP
CHANCES...HOWEVER THE GFS WOULD FAVOR HEAVIER AMOUNTS NEAR THE
CASCADES AND LEE SLOPES...WHEREAS THE ENSEMBLE MEAN AND ECMWF
WOULD SPREAD THE HEAVIER PRECIP INTO NORTH IDAHO. GIVEN THE COLD
IN SITU AIRMASS...THE PRECIP WILL DEFINITELY FALL AS SNOW...SOME
OF WHICH COULD BE HEAVY AT TIMES DEPENDING ON WHICH MODEL
VERIFIES. FX

&&

.AVIATION...
DRIER AIR WORKING INTO THE REGION TODAY WILL KEEP CIGS VFR AT ALL
TAF LOCATIONS.  AN APPROACHING PACIFIC SYSTEM AND AN ASSOCIATED WARM
FRONT WILL BRING INCREASING CLOUDS ACROSS THE AREA TONIGHT INTO
SATURDAY MORNING.  FOR KEAT/KMWH...LIGHT SNOW WILL LIKELY DEVELOP
BTWN 12-18Z SAT WITH LOWERING CIGS/VSBYS.  THE -SN WILL SPREAD EAST
INTO EASTERN WA/ID NEAR OR SHORTLY AFTER 18Z SAT.  JW
