AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
230 PM PST THU NOV 2 2006

.SYNOPSIS...A SERIES OF STRONG AND WET PACIFIC STORMS WILL PASS
THROUGH THE REGION OVER THE NEXT WEEK FOR AN ACTIVE AUTUMN
WEATHER REGIME.

&&

.DISCUSSION...
TONIGHT AND FRIDAY...COLD AND DRY POLAR AIR MASS WHICH HAS TAKEN UP
RESIDENCE OVER THE REGION IS IN THE PROCESS OF BEING EVICTED BY THE
FIRST IN A SERIES OF STRONG AND MOIST PACIFIC WEATHER SYSTEMS.
PACIFIC SATELLITE INDICATES THE CURRENT STORM FOCUSING DYNAMIC ENERGY
AND A WARM OCCLUDED FRONT INTO THE REGION THIS AFTERNOON...FOLLOWED
UPSTREAM BY ANOTHER STRONG SYSTEM NEAR 150W AIMING FOR THE NORTHWEST.

MODELS ARE SIMILAR WITH OVERALL SYNOPTIC FIELDS OF MOTION...WITH
SOME MODERATE BUT CRITICAL DIFFERENCES REGARDING LOW LEVEL AIR MASS
CHARACTERISTICS. THUS MUCH OF THE NEAR-NEAR TERM FORECAST
IS EXTRAPOLATED FROM OBSERVATIONAL DATA AND EXPERIENCE WITH SIMILAR
EVENTS...AND BACKED UP BY MODEL DATA WHERE DATA FOR THOSE ELEMENTS
FOR WHICH MARGINAL MODEL AGREEMENT EXISTS.

TONIGHT AND INTO FRIDAY MORNING THE PROBLEM WILL BE THE SCRUBBING
PROCESS AND ASSOCIATED METEOROLOGICAL HEADACHES AND HAZARDS UNTIL
THE SURFACE WARM FRONT FINALLY PLOWS THROUGH AND SENDS FREEZING
LEVELS BACK UP TO THE HIGHEST PEAKS. SURFACE OBSERVATIONS SUGGEST
WARM FRONT LAYS ALONG A LINE FROM ABOUT SEATTLE TO PENDLETON AT 200
PM. FORECAST AREA CAN BE BROKEN INTO 3 REGIMES FOR THE NEXT 24 HOURS.
FIRST IN THE WEST ALONG THE CASCADES AND THE IMMEDIATE LEE VALLEYS
AND WATERVILLE REGION...MAINLY LIGHT SNOW HAS BEEN FALLING AT
MOST LOCATIONS ALL DAY. ELLENSBURG AND YAKIMA HAVE SWITCHED OVER TO
RAIN WHILE WENATCHEE...ON THE OTHER SIDE OF MISSION RIDGE IS STILL
SNOW. EXPECT A MESSY TRANSITION PERIOD THIS EVENING WITH SNOW TURNING
TO SLEET AND/OR FREEZING RAIN AS MID LEVEL WARMING SLOPS OVER THE
RIDGE AND RIDES OVER THE COOL AIR TRAPPED IN THE COLUMBIA RIVER
VALLEY. CONFIDENCE IS LIMITED AS TO HOW LONG THIS TRANSITION PERIOD
WILL LAST...BUT THE GOOD NEWS IS GROUND TEMPERATURES APPEAR TO BE
WARM ENOUGH TO PREVENT SIGNIFICANT ICE ACCUMULATION ON ROADS. FROM
SOUTH TO NORTH IN THE WENATCHEE-OMAK CORRIDOR PRECIPITATION WILL
PROBABLY CHANGE TO RAIN OVERNIGHT AND INTO FRIDAY MORNING...THEN
TAPER OFF TO SHOWERS IN THE BREAK PERIOD BETWEEN WEATHER SYSTEMS.
CURRENT WINTER WEATHER ADVISORY HIGHLIGHTS WILL REMAIN AS IS THROUGH
THIS EVENING.

IN THE MAIN BASIN REGION FROM MOSES LAKE TO THE SPOKANE /CDA
REGION AND POINTS SOUTH...GENERAL SMOOTH PROGRESSION OF THE WARM
FRONT WILL GRADUALLY TRANSITION CURRENT SNOW OVER TO RAIN THIS
EVENING WITH AN INCREASE IN WINDS AND STEADY PRECIPITATION TAPERING
OFF TO SHOWERS LATER THIS EVENING. PURCELL TRENCH WINDS ARE
DECREASING IN RESPONSE TO WEAKENING CRESTON TO SPOKANE GRADIENT FOR
LITTLE THREAT OF EAST WIND CONTINUOUS DRYING AND ASSOCIATED
FREEZING RAIN THREAT AS THE FRONT APPROACHES. UNTIL CHANGE OVER...
GROUND TEMPERATURES ARE STILL HIGH ENOUGH TO PREVENT SIGNIFICANT
SNOW ACCUMULATION EXCEPT ON GRASSY SURFACES.

TO THE NORTH OVER THE NORTHEAST WASHINGTON MOUNTAINS AND NORTHERN
PANHANDLE MOUNTAINS THE THREAT OF PROLONGED PRECIPITATION DUE TO
ISENTROPIC ASCENT AUGMENTED BY OROGRAPHY...AND THE DIFFICULTY
OF FRONTAL SCRUBBING OF PROTECTED NARROW VALLEYS...WILL LEAD TO AN
EXTENDED PERIOD OF MAINLY SNOW OVERNIGHT WITH VALLEY ACCUMULATION OF
A COUPLE INCHES...HIGHEST AMOUNTS CLOSER TO CANADA...AND
MOUNTAIN SNOW APPROACHING OR MINIMALLY ACHIEVING HEAVY SNOW CRITERIA.
TRANSITION PRECIPITATION PHASE CHANGES TO SLEET AND POCKETS OF
FREEZING RAIN ALSO A THREAT IN THE SOUTHERN VALLEYS OF THESE ZONES
OVERNIGHT. WILL UPGRADE THE CURRENT WINTER WEATHER ADVISORY TO A
WINTER STORM WARNING TO COVER THIS MESSY TRANSITION TONIGHT.

OVERNIGHT MINIMUM TEMPERATURES WILL LIKELY BE ACHIEVED EARLY THIS
EVENING...THEN STEADY OUT OR RISE SLIGHTLY OVERNIGHT AS WARM SECTOR
ENCOMPASSES THE REGION. FRIDAY WILL BE A RELATIVE BREAK PERIOD
BETWEEN STRONG SYSTEMS WITH PRECIPITATION THREAT MAINLY CONSISTING
OF HIT AND MISS SHOWERS. HIGH TEMPERATURES FRIDAY DRAMATICALLY
WARMER WITH BREEZY CONDITIONS CREATING GOOD MIXING AND ADIABATIC
WARMING OF MID LEVEL WARM SECTOR AIR DOWN TO THE SURFACE...
ESPECIALLY OVER THE EASTERN COLUMBIA BASIN. /FUGAZZI

FRIDAY NIGHT THROUGH SATURDAY NIGHT...WET PATTERN DURING THIS
PERIOD AS A MOIST SOUTHWEST FLOW USHERS IN ONE PACIFIC WARM FRONT
FRIDAY NIGHT INTO SATURDAY...FOLLOWED BY ANOTHER SATURDAY NIGHT.
CONFIDENCE IS HIGH THAT MOST PLACES WILL GET MEASURABLE RAINFALL
DURING THIS TIME FRAME. THIS FLOW WILL BE UPSLOPE INTO THE
MOUNTAINS OF NE WASHINGTON AND THE IDAHO PANHANDLE WHICH WILL
ENHANCE PRECIPITATION AMOUNTS...WITH QPF AMOUNTS FROM GFS AND NAM
MODELS SUGGESTING NEAR AN INCH OF RAINFALL. THE IMMEDIATE EAST
SLOPES NEAR THE CASCADE CREST WILL ALSO GET A GOOD SHOT OF
MOISTURE FROM THIS SYSTEM. SNOW LEVELS FRIDAY NIGHT THROUGH
SATURDAY EVENING WILL RANGE FROM 6000-7000 FEET...THEN LOWER TO
5500-6000 FEET LATE SATURDAY NIGHT. TEMPERATURES WILL BE ABOVE
NORMAL AT NIGHT GIVEN CLOUD COVER AND MOISTURE...AND SLIGHTLY
ABOVE NORMAL DURING THE DAY. JW

SUNDAY THROUGH THURS...THE FOCUS OF THE EXTENDED-RANGE FCST WILL BE
NAILING DOWN PCPN AMNTS. INBOUND WARM-FRONT AT THE LEADING EDGE OF A
VERY WET AND MILD PATTERN WILL ALREADY MAKE LANDFALL ALONG THE
COAST OF THE PAC NW BY LATE SUNDAY. BY MON AFTERNOON...A LONG AND
DEEP FETCH OF SUB-TROPICAL MOISTURE ALONG THE WARM CONVEYOR BELT
ACCOMPANYING THE COLD-FRONT WILL HIT THE REGION HEAD-ON. AND GIVEN
THE PWAT VALUES WELL IN EXCESS OF ONE INCH...HIGH SNOW LEVELS AND
DEEP WLY FLOW...QUITE A BIT OF PCPN SHOULD FALL NEAR THE CASCADE
CREST AND OVER THE MTS OF N ID FROM SUNDAY NT INTO TUES. RIVER RISES
WILL BE LIKELY...ESPECIALLY AROUND THE STEHEKIN AREA AND FOR ALL
RIVERS WITH THEIR HEADWATERS IN THE CASCADES. ALL FCST RIVER RISES
WILL BE MONITORED CLOSELY FOR ANY PSBL WATCHES IN THE NEXT FEW DAYS.
WEVE INCREASED PCPN AMNTS FOR NEARLY ALL FCST ZONES FOR LATE SUNDAY
THROUGH MON NT BEFORE THE COLD-FRONT MOVES INTO THE NRN ROCKIES AND
OUT OF ERN WA. HAVE KEPT THE BEST CHANCE OF SHOWERS IN THE FCST FOR
TUES AND WED ACROSS N ID IN THE UNSTABLE POST-FRONTAL AIR MASS. NO
OTHER CHANGES TO THE PREVIOUS FCST. BZ

&&

.AVIATION...MOISTURE WILL CONTINUE TO STREAM INTO THE AREA
TODAY...WITH VARYING CEILINGS AND VISIBILITIES ACROSS THE AREA.
COLD AIR DAMMING NEAR THE CASCADES WILL CONTINUE TO PRODUCE -SN AT
KEAT WITH IFR CONDITIONS THROUGH 21Z. -SN WILL THEN CHANGE TO A
MIX OF -SN AND -FZRA AT KEAT BETWEEN 21-00Z...BEFORE CHANGING TO
JUST -FZRA DURING THE EARLY EVENING. AT
KGEG/KSFF/KCOE...PRECIPITATION WILL START OFF AS A MIXTURE OF RAIN
AND SNOW WITH OCCASIONALLY MVFR VIS/CEILINGS DEVELOPING. THEN
OVERNIGHT SHOULD SEE JUST RAIN BUT WITH CONTINUED MVFR
CEILINGS...BUT WITH VISIBILITIES LIKELY IMPROVING GIVEN RAIN
INSTEAD OF SNOW FALLING. AT KLWS/KPUW...DRIER LOW LEVEL AIR MASS
WILL KEEP CLOUD BASES HIGHER WITH HEIGHTS IN THE VFR CATEGORY. JW
