AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
210 AM PST SUN DEC 7 2008

.SYNOPSIS...
A WEATHER SYSTEM WILL DROP OUT OF CANADA TODAY AND TONIGHT BRINGING
MAINLY VALLEY RAIN AND SOME HEAVY MOUNTAIN SNOW ESPECIALLY OVER
THE IDAHO PANHANDLE. THIS STORM WILL EXIT THE REGION TO THE EAST ON
MONDAY. CONDITIONS WILL BECOME GENERALLY DRY LATE MONDAY AND INTO
TUESDAY. ANOTHER WEAK SYSTEM WILL BRING MORE MOUNTAIN SNOW TUESDAY
NIGHT AND WEDNESDAY. BIG CHANGES ARE LIKELY BY THE END OF THE WEEK
AS A DEEP AND COLD UPPER LEVEL LOW MOVES OVER THE PACIFIC
NORTHWEST. THIS SYSTEM SHOULD BRING THE COLDEST WEATHER SO FAR
THIS SEASON AS WELL AS A GOOD POSSIBILITY OF SNOW FOR MOST
LOCATIONS.

&&

.DISCUSSION...
TODAY THROUGH MONDAY...SATELLITE INDICATES THE POLAR STORM TRACK
IS LINING UP ON THE SAME LATITUDE AS THE FORECAST AREA THIS
MORNING. LATEST NAM AND GFS MODELS ARE IN REASONABLY GOOD
AGREEMENT WITH THE EXPECTED FIELD OF MOTION AND ARE PLAUSIBLE
AGAINST SATELLITE EXTRAPOLATION. THIS STORM TRACK ALONG WITH A
MODERATE FETCH OF PACIFIC MOISTURE WILL SLUMP DOWN OVER THE
FORECAST AREA TODAY WHERE A POLAR FRONTAL BOUNDARY WILL FOCUS
INCOMING MOISTURE INTO MAINLY VALLEY RAIN AND MOUNTAIN SNOW.
INITIAL VALLEY PRECIPITATION WILL LIKELY BE SNOW OR A WINTRY MIX IN
THE VALLEYS NORTH OF THE COLUMBIA BASIN WHERE THE CURRENT WINTER
WEATHER ADVISORY WILL CONTINUE THROUGH THIS MORNING. WITH MAINLY
ZONAL FLOW EXPECTED OVER THE REGION...THE HIGH CASCADES AND IDAHO
PANHANDLE MOUNTAINS WILL PICK UP MODERATE ACCUMULATIONS OF SNOW
ABOVE 4000 FEET OR SO...WITH THE NORTHERN VALLEYS PROBABLY
CHANGING OVER TO A RAIN AND WET SNOW MIX BY AFTERNOON...EFFECTIVELY
ENDING THE POPULATED NORTHERN VALLEYS WINTER WEATHER HAZARD
REGIME. THIS FLOW REGIME WILL PROBABLY KEEP PRECIPITATION RARE AND
SPOTTY IN THE DEEP BASIN AND CASCADES LEE ZONES...WITH OROGRAPHIC
ENHANCEMENT CAUSING MORE WIDESPREAD RAIN BY AFTERNOON OVER THE
RISING TERRAIN OF THE EASTERN BASIN.

TONIGHT THE UPPER LEVEL FLOW WILL BUCKLE AND BECOME MORE NORTHERLY
WITH AN UPPER LEVEL TROUGH DIGGING OUT OF THE NORTH AND INTO IDAHO
OVERNIGHT. THIS WAVE WILL HAVE SOME DECENT JET AND VORTICITY
DYNAMIC SUPPORT AS WELL AS THE FAVORABLE OROGRAPHIC UPSLOPE INTO
THE PANHANDLE MOUNTAINS. MOISTURE AND LIFT WILL PROBABLY BE
ADEQUATE TO ACHIEVE AT LEAST LOW END HEAVY SNOW CRITERIA AMOUNTS
OVER THE HIGHER TERRAIN AND THUS A WINTER STORM WARNING FOR HEAVY
SNOW WILL BE ISSUED WITH THE MORNING FORECAST ISSUANCE. OUTSIDE OF
THE CENTRAL PANHANDLE MOUNTAINS AS THIS WAVE DROPS THROUGH
TONIGHT A RISK OF HIT AND MISS SNOW SHOWERS WILL DEVELOP OVER THE
PALOUSE AND SPOKANE AREA WITH MODEL SOUNDINGS INDICATING UNSTABLE
LAPSE RATES UNDER THE TROUGH CUSP COLD POOL ALOFT. THIS REGIME
COULD CREATE MINOR OR EVEN LOCALLY A FEW INCHES OF ACCUMULATIONS
BY MONDAY MORNING OVER THE EASTERN COLUMBIA BASIN LOCATIONS AND
MAKE THE MONDAY MORNING COMMUTE A BIT HAZARDOUS. STILL TOO EARLY
TO PIN DOWN THIS THREAT FROM THESE SCATTERED SHOWERS AND POSSIBLE SNOW
BANDS.

ON MONDAY THE WEATHER SYSTEM WILL EXIT THE REGION THROUGH THE
SOUTHEASTERN ZONES AND A GENERALLY DRY BUT COOL NORTHERLY FLOW REGIME
WILL TAKE OVER WITH A BACKSIDE UPPER RIDGE BEGINNING TO BUILD OVER
THE REGION AND A SIGNIFICANTLY COOLER AIR MASS OCCUPYING THE
BASIN. /FUGAZZI

MONDAY NIGHT WILL BE A TRANSITION PERIOD. THE UPPER LEVEL FLOW
CONTINUES FROM THE NORTH AS A RIDGE BUILDS OFF THE COAST. WARMING
ALOFT WILL YIELD TO MORE STABLE CONDITIONS...YET LOW LEVEL
WESTERLY FLOW AND SHALLOW CONVECTION WILL KEEP OROGRAPHIC SHOWERS
IN THE IDAHO PANHANDLE.

TUESDAY THROUGH WEDNESDAY WILL BE UNDER A DIRTY RIDGE. THE UPPER
LEVEL RIDGE BUILDS OVER THE REGION WHILE ISENTROPIC LIFT AND
MOISTURE INCREASE AND LOWER THROUGH THE ATMOSPHERE. A WARM FRONT
MOVES ACROSS EASTERN WASHINGTON AND NORTH IDAHO TUESDAY...AS WARM
AIR SCOURS OUT THE BASIN AND PUSHES TOWARD THE NORTHERN VALLEYS
OF WASHINGTON AND THE IDAHO PANHANDLE. THE NAM IS QUICKER ON
MOVING THE COLD AIR OUT...WHILE THE GFS LINGERS 850MB TEMPS BELOW
ZERO NEAR THE CANADIAN BORDER INTO TUESDAY EVENING. THEN THE
MOIST BOUNDARY BEGINS TO SAG SOUTH AS A SHORTWAVE ALOFT SLIDES UP
AND OVER THE RIDGE LATE TUESDAY NIGHT. BY WEDNESDAY...THE FRONTAL BOUNDARY
SINKS AGAIN WITH ANOTHER PASSING SHORTWAVE. TEMPERATURES WILL RISE
ABOVE NORMAL.

WEDNESDAY NIGHT THROUGH THURSDAY NIGHT...THE RIDGE RETROGRADES
WHILE JET SUPPORTS WEAKENS. BY WEDNESDAY NIGHT...THE REMAINS OF
THE FRONTAL BOUNDARY DROP SOUTH OF THE FORECAST AREA. INSTABILITY
INCREASING WITH COOLING ALOFT AND SHOWERS WILL LINGER ACROSS SE
WA AND SOUTHERN PANHANDLE THROUGH THURSDAY. A SHORTWAVE PASSES
ACROSS BC/ALBERTA...HELPING TO VEER THE FLOW ALOFT TO NW BY THURSDAY
NIGHT. THEN ENERGY DROPS INTO MONTANA WITH SHOWERS IN CENTRAL AND
SOUTHERN PANHANDLE. MORE ABOVE NORMAL TEMPERATURES EXPECTED.

FOR FRIDAY THROUGH THE WEEKEND...THERE IS GOOD AGREEMENT THAT AN
UNSEASONABLY COLD AREA OF LOW PRESSURE WILL DROP ACROSS THE
PACIFIC NORTHWEST. YET TIMING AND PLACEMENTS DIFFERENCES ABOUND
WITH THE TRACK. NORTHWEST FLOW CONTINUES FRIDAY AS A MAJOR
SHORTWAVE MOVES IN FROM VANCOUVER ISLAND. THEN...INSTABILITY
INCREASES FRIDAY NIGHT AS THE TROUGH DIGS AND DROPS OVER
WASHINGTON. IT BECOMES QUITE UNSTABLE AS THE TROUGH SLOWLY PUSHES
SOUTH INTO OREGON. TEMPERATURES TAKE A NOSE DIVE WITH 850MB
READINGS RANGING FROM -12 TO -19C. TEMPERATURES WILL REMAIN BELOW
FREEZING WITH ANY PRECIPITATION FALLING IN THE FORM OF SNOW. THERE
IS A GOOD CHANCE THAT THE MAIN THREAT FOR SNOW WILL BE FRIDAY
NIGHT INTO SATURDAY...FOLLOWED BY A DRIER NORTHERLY FLOW INTO
SUNDAY. YET DUE TO THE TRACK AND SPEED OF THE UPPER LOW...WILL
KEEP POPS CLOSE TO CLIMO THROUGH THE WEEKEND AND KEEP A CHANCE OF
SNOW MENTIONED THROUGH THE PERIOD. TEMPERATURES WILL BE 5-10
DEGREES BELOW NORMAL...AND POSSIBLY EVEN COLDER IF UNDER ANY
APPRECIABLE FRESH SNOW COVER. /RFOX.

&&

.AVIATION...
A COLD FRONT OVER VANCOUVER ISLAND WILL DROP SOUTHEAST OVER THE AREA
TONIGHT AND TOMORROW.  FRONT PASSAGE WILL RESULT IN A MIXED BAG OF
PRECIP...WITH -SHRAPL EXPECTED AT KGEG/KSFF/KCOE.  THIS FRONT SHOULD
HELP SCOUR OUT THE PATCHY FG THAT WILL AFFECT KSFF TONIGHT.  FOR
KPUW/KLWS THE AIR MASS WILL BE WARMER SUPPORTING JUST -RA.  HOWEVER
CIGS WILL LOWER ACROSS EASTERN WA/N IDAHO WITH MVFR CIGS LIKELY WITH
TERRAIN OBSCURATIONS.  WESTERLY FLOW IN THE MID LEVELS WILL LEAD TO
RAIN SHADOWING AT KEAT/KMWH WHERE CIGS WILL REMAIN VFR.  JW
