AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
238 AM PST THU DEC 31 2009

.SYNOPSIS...A STRONG STORM SYSTEM WILL QUICKLY PASS THROUGH THE
REGION THIS AFTERNOON AND EVENING DELIVERING WIDESPREAD MODERATE
SNOW ACCUMULATIONS...WITH A MESSY WINTRY MIX NEAR THE CASCADES.
AN ACTIVE AND UNSETTLED WEATHER PATTERN WILL CONTINUE FEATURING
SCATTERED MOUNTAIN SNOW SHOWERS AND VALLEY RAIN OR SNOW SHOWERS
THROUGH THE WEEKEND AND INTO NEXT WEEK.

&&

.DISCUSSION...
TODAY AND TONIGHT...

...STORMY AND WINTRY CONDITIONS FOR THE NEW YEARS EVE TRAVEL
AND CELEBRATION PERIOD TONIGHT...

TODAY...A SHORT BREAK PERIOD BETWEEN STORMS WILL PREVAIL THROUGH
THE MORNING IN THE WEST AND THROUGH MUCH OF THE DAY IN THE EAST.
MOIST COOL AND LOCALLY FOGGY CONDITIONS ARE LIKELY WITH LITTLE
SUN AND CONTINUED SEASONABLY COOL HIGH TEMPERATURES AS THE NEXT
SYSTEM APPROACHES THE REGION.

TONIGHT...SATELLITE DISPLAYS A DEEP GULF OF ALASKA CYCLONE THIS
MORNING WITH AN APPENDING OCCLUDED FRONT CLOSING IN ON THE
NORTHWEST COAST. LATEST NAM/GFS AND ECMWF MODELS INITIALIZE WELL
WITH THIS FEATURE AND ARE SIMILAR IN HANDLING THE PASSAGE OF THIS
FRONT THROUGH THE FORECAST AREA. THIS STORM WILL MANIFEST ITSELF
AS A STRONG OCCLUDED FRONT PASSAGE WITH STRONG DYNAMIC SUPPORT
ALOFT IN ADDITION TO DEEP AND MOIST ISENTROPIC ASCENT. THE PACIFIC
MOISTURE FETCH IS BETTER ORIENTED AND DEEPER THAN YESTERDAYS
SYSTEM. STARTING OVER THE CASCADES AND DEEP BASIN ZONES THIS
AFTERNOON...AND THROUGH THE EASTERN ZONES THIS EVENING...JUST
ABOUT ALL LOCATIONS WILL BE RUN OVER WITH A FEW HOUR BURST OF
MODERATE TO LOCALLY HEAVY SNOW FALL RATES. THE SAVING GRACE
PREVENTING WIDESPREAD HEAVY SNOW ACCUMULATIONS WILL BE THE SPEED
OF THE SYSTEM WHICH IS EXPECTED TO RIP THROUGH THE ENTIRE FORECAST
AREA AND BE GONE BY 12Z FRIDAY WITH ONLY THE USUAL LINGERING
OROGRAPHIC SNOW SHOWERS IN THE IDAHO PANHANDLE AND NEAR THE
CASCADE CREST. THIS IS A WARM OCCLUSION...THUS SNOW LEVELS SHOULD
RISE QUITE DRAMATICALLY OVER THE SOUTHERN FORECAST AREA
TONIGHT...THE PROBLEM IS BY THE TIME THE SNOW LEVELS RISE...THE
DRY SLOT WILL BE PASSING THROUGH AND EFFECTIVELY ENDING OR
DRAMATICALLY DECREASING PRECIPITATION. THUS...EXCEPT FOR THE
SOUTHEASTERN ZONES...MOST OF THE PRECIPITATION ASSOCIATED WITH
THIS SYSTEM WILL BE SNOW...OR A WINTRY MIX OF RAIN/SNOW/SLEET AND
FREEZING RAIN IN THE DEEP BASIN AND SOUTHERN CASCADE VALLEYS. IN
RESPONSE TO THIS IMPENDING MESS AND DUE TO THE FACT THAT TONIGHT
WILL BE A BUSY EVENING ON THE HIGHWAYS...A SLEW OF WINTER WEATHER
ADVISORIES WILL BE ISSUED WITH THE MORNING PRODUCT FLOOD. CURRENT
WATCHES WILL BE UPGRADED TO WARNINGS ONLY IN THE DEEP BASIN AND
OKANOGAN VALLEY WHERE CONFIDENCE IS HIGHEST FOR LOW END HEAVY SNOW
CRITERIA TO BE MET AS LOW LEVEL UPSLOPE WIND COMPONENT WILL AID
THE SNOW ACCUMULATION RATES ...AS WELL AS THE ADDED THREAT OF MIXED
AND FREEZING PRECIPITATION MENACING THESE ZONES THROUGH THE NIGHT.

BY FRIDAY DAWN MOST OF THE REGION WILL BE IN THE POST-FRONTAL
SHOWERY AIR MASS...WITH SHOWER ACTIVITY SPARSEST IN THE
BASIN...AND DENSEST OVER THE MOUNTAINS OF THE IDAHO PANHANDLE.
/FUGAZZI

NEW YEARS DAY THROUGH SATURDAY NIGHT...MODEL AGREEMENT IS GOOD
WITH AN OCCLUDED LOW WEAKENING AND MOVING EAST ACROSS SOUTHERN
BRITISH COLUMBIA ON NEW YEARS DAY AND NIGHT. THIS TRACK WILL
RESULT IN INCREASING SOUTHERLY PRESSURE GRADIENTS RESULTING IN
RISING SNOW LEVELS. AS THE LOW PASSES BY TO THE NORTH...A STRONG
SHORT WAVE WILL TRACK ACROSS THE INLAND NW. IN ADDITION...850MB
WIND FLOW OF 20-30 KTS OUT OF THE WEST-SOUTHWEST WILL PROVIDE
UPSLOPE LIFT INTO THE CASCADES AND THE MOUNTAINS OF NE WA/N IDAHO.
THIS WILL RESULT IN ADDITIONAL MODERATE SNOW ACCUMULATIONS IN THE
MOUNTAINS. MEANWHILE IN THE LEE OF THE CASCADES DOWNSLOPE FLOW OFF
THE CASCADES INTO THE COLUMBIA BASIN WILL ONLY RESULT IN A CHANCE
OF PRECIPITATION.

TRICKY PART OF THE FORECAST IS PRECIPITATION TYPE. BY THE
AFTERNOON IT APPEARS FROM MODEL GUIDANCE THAT TEMPERATURES WILL BE
WARM ENOUGH FOR RAIN IN THE VALLEYS DUE TO INCREASING SOUTHERLY
WINDS...BUT MAY BE MIXED WITH SNOW NORTH OF HIGHWAY 2. IN THE
MORNING HOWEVER AS THE SHORT WAVE BEGINS TO CROSS THE
CASCADES...NAM 1000-850MB THICKNESSES AND INSPECTION OF MODEL
SOUNDINGS SUGGEST COLD AIR REMAINING TRAPPED ALONG THE EAST SLOPES
OF THE NORTH WA CASCADES...NORTH OF HIGHWAY 2...AND IN THE MOSES
LAKE/WENATCHEE AREAS. NAM SUGGESTS THE COLD AIR WILL BE DEEP
ENOUGH FOR CONTINUED LOW SNOW LEVELS IN THESE AREAS...EXCEPT THE
MOSES LAKE AREA WHERE THE WARM TONGUE GETS ABOVE FREEZING WHILE
SFC TEMPS ARE NEAR OR BELOW FREEZING. THUS A CHANCE OF FREEZING
RAIN IS FCST NEW YEARS DAY MORNING. SHALLOW COLD AIR MAY ALSO BE
SLOWER TO SCOUR OUT FOR THE DEER PARK...SPRINGDALE...SANDPOINT
AREAS WHERE A CHANCE OF FREEZING RAIN IS ALSO FCST.

ON SATURDAY THE PATTERN REMAINS SIMILAR WITH SOUTHERLY WINDS
KEEPING SNOW LEVELS MAINLY ABOVE THE VALLEY FLOORS WITH MOIST
WESTERLY FLOW CONTINUING TO FAVOR THE MOUNTAINS FOR ADDITIONAL
ACCUMULATING SNOWFALL.

SUNDAY THROUGH WEDNESDAY...OVERALL CONFIDENCE IS LOW DURING THESE
PERIODS WITH DIFFERING MODEL SOLUTIONS. FIRST AREA OF UNCERTAINTY
IS THE STRENGTH/TRACK OF A SFC LOW COMING UP FROM THE SOUTHWEST
ON MONDAY AND WHETHER OR NOT THIS LOW WILL HAVE ANY IMPACTS ON
EASTERN WA/N IDAHO. AFTER THIS SOME MODEL SOLUTIONS BUILD A RIDGE
OFFSHORE AND BRING IN A SHOT OF COLDER AIR ON TUESDAY...WHILE
OTHER SOLUTIONS ONLY GIVE THE AREA A GLANCING SHOT OF COLD AIR AS
THE RIDGE AXIS IS OVER THE AREA. STILL OTHER SOLUTIONS UNDERCUT THE
RIDGE WITH PACIFIC ENERGY FOR A CHANCE OF PRECIPITATION OVER THE
AREA.  THE TREND IN THE NEW GUIDANCE IS FOR COOLER TEMPS MID WEEK
SO TEMPERATURES WERE NUDGED DOWN. JW

&&

.AVIATION...
SEVERAL WEATHER FEATURES IMPACTING THE INLAND NW DURING THE
NEXT 24 HRS WILL RESULT IN LARGE IMPACTS TO THE AVIATION
COMMUNITY. THE FIRST FEATURE IS THE WIDESPREAD STRATUS AND FOG
WHICH WILL PLAGUE MUCH OF THE BASIN...PALOUSE...AND EAST SLOPES.
OVERNIGHT INTO TOMORROW YIELDING IFR/LIFR CIGS AS WELL AS
LOCAL AREAS OF FZFG. EXPECT SOME IMPROVEMENT STARTING
AT KLWS- KPUW...THEN NORTHWARD TO THE SPOKANE CORRIDOR BY 18Z IN
RESPONSE TO INCR SOUTHERLY FLOW AS A STRONG PACIFIC STORM NEARS
THE COAST. THE SECOND ELEMENT WILL BE SCATTERED SNOW SHWRS
