AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
343 PM PST WED JAN 7 2009

.SYNOPSIS...
A MOIST AND MILD SUBTROPICAL AIRMASS WILL INCREASE THE THREAT OF
SIGNIFICANT VALLEY RAINS...RISING SNOW LEVELS...AND GUSTY WINDS
THROUGH THURSDAY. URBAN AND SMALL STREAM FLOODING IS EXPECTED OVER
PORTIONS OF REGION THROUGH EARLY FRIDAY. DRIER WEATHER IS EXPECTED
FOR FRIDAY INTO THE WEEKEND WITH TEMPERATURES RETURNING TO SEASONAL
LEVELS. THIS WILL DRAMATICALLY LOWER THE THREAT OF FLOODING.

&&

.DISCUSSION...
TONIGHT AND THURSDAY...A PLUME OF SUB-TROPICAL MOISTURE EVIDENT ON
SATELLITE WATER VAPOR IMAGERY THIS AFTERNOON...WILL CONTINUE TO
BRING SIGNIFICANT RAINFALL TO THE REGION. THE MILD TEMPERATURES WILL
CONTINUE OVERNIGHT AS STRONG SOUTHWEST 850MB WINDS PUSH A WARM AND
MOIST AIRMASS OVER THE INLAND NORTHWEST. SNOW LEVELS WILL CONTINUE
TO BE QUITE HIGH WITH SNOW POSSIBLE ONLY OVER THE HIGHEST TERRAIN OF
THE CASCADES AND THE IDAHO PANHANDLE MOUNTAINS. STEADY RAINFALL THIS
AFTERNOON HAS TAKEN ON AN OROGRAPHIC LOOK AS STRONG WESTERLY WINDS
HAVE CREATED A LEE SIDE RAIN SHADOW THAT EXTENDS ACROSS THE BASIN TO
THE SPOKANE AREA. AS A SHORTWAVE TROUGH AND A SURFACE COLD FRONT
SWING THROUGH THE REGION ON THURSDAY...MID LEVEL WINDS WILL BACK TO
THE SOUTHWEST...LIMITING THE RAIN SHADOW AND BRINGING ANOTHER PERIOD
OF RAIN TO MUCH OF THE FORECAST AREA. THE COMBINATION OF MILD
TEMPERATURES AND STEADY RAIN WILL CONTINUE TO MELT THE CONSIDERABLE
SNOWPACK ACROSS THE AREA. SIGNIFICANT RUNOFF WILL CAUSE FLOODING
CONCERNS FOR MANY OF THE SMALL STREAM AND CREEKS ACROSS THE FORECAST
AREA. THERE IS ALSO THE POTENTIAL FOR ICE JAM BREAKUPS THAT CAN
CAUSE RAPID FLUCTUATIONS ON STREAMS AND RIVERS. FLOOD WARNINGS AND
ADVISORIES HAVE BEEN ISSUED FOR MUCH OF THE FORECAST AREA OUTSIDE OF
THE BASIN.

WINDS REMAIN GUSTY ACROSS PORTIONS OF THE PALOUSE AND THE
WEST PLAINS AS WELL AS THE WENATCHEE AND OMAK AREAS THIS AFTERNOON
BUT ARE EXPECTED TO CONTINUE BELOW ADVISORY LEVELS AND DIMINISH
SOMEWHAT OVERNIGHT. AS THE COLD FRONT PASSES THROUGH THURSDAY
AFTERNOON WINDS WILL INCREASE ONCE AGAIN BUT DO NOT EXPECT THEM TO
REACH ADVISORY CRITERIA. MODEL BOUNDARY LAYER WIND SPEEDS FOR THE
VALLEYS GENERALLY REMAIN AT OR BELOW 25KTS EXCEPT FOR IN THE
WENATCHEE AREA. WE WILL HAVE TO KEEP AN EYE ON THIS AREA BUT NO
WIND HIGHLIGHTS ISSUED AT THIS TIME. /KELCH

THURSDAY NIGHT THROUGH WEDNESDAY...THE BIG STORY FOR THIS PORTION
OF THE FORECAST WILL BE THE TEMPORARY HALT IN SNOW MELT THURSDAY
NIGHT THROUGH FRIDAY NIGHT BEFORE A BRIEF WARMUP ACROSS THE
SOUTHEASTERN CWA AND MUCH...MUCH DRIER CONDITIONS BUILDING INTO
THE AREA. THE SHORT WAVE TROUGH ASSOCIATED WITH THE COLD FRONT
THAT PASSES THE AREA THURSDAY EVENING WILL MOVE EAST BY FRIDAY.
COLD ADVECTION BEHIND THAT FRONT WILL DROP OUR TEMPERATURES BELOW
FREEZING ACROSS MOST OF THE CWA FOR ABOUT 24-36 HOURS. THIS SHOULD
ALLOW A REFREEZE AND TEMPORARY HALT IN RUNOFF INTO LOCAL STREAMS
AND RIVERS.

THE SYSTEM THAT MOVES THROUGH THURSDAY NIGHT DOES HAVE A FAIR
AMOUNT OF MOMENTUM ASSOCIATED WITH IT. BUFKIT SOUNDINGS SHOW A
NICE NORTHWESTERLY FLOW TRAJECTORY WITH AN INVERSION SOMEWHERE
JUST ABOVE THE CASCADE MOUNTAINTOPS AND AROUND 45 KTS BELOW THAT
INVERSION. CHANNELED FLOW BELOW THE INVERSION SHOULD MIX OUT TO
THE SURFACE AROUND WENATCHEE AND THE PALOUSE AND POMEROY AREAS
DURING THE EVENING THURSDAY RESULTING IN SOME WINDY CONDITIONS FOR
TIMES BEFORE THE COLD ADVECTION WANES AND MOMENTUM WEAKENS
OVERNIGHT.

BEHIND THURSDAY NIGHTS FRONT...LARGE SCALE RIDGING BEGINS TO POKE
UP OFF SHORE. HOWEVER...AHEAD OF THAT...ONE MORE WEAK WAVE TRIES
TO ROUND THE TOP OF THE RIDGE AND DOWN THE LEE OF THE ROCKIES.
WHILE LITTLE QPF IS EXPECTED WITH THIS SYSTEM...LOW LEVEL FLOW
AROUND 50 KTS AGAIN IS EXPECTED WITH SOUNDINGS SUGGESTING SOME
MIXING TO THE SURFACE IS POSSIBLE ACROSS THE PALOUSE AND POMEROY
AREAS YET AGAIN. SOUTHWESTERLY FLOW THIS TIME MEANS UPSLOPE FLOW
CONDITIONS INTO THE IDAHO PANHANDLE AND NORTHEASTERN WASHINGTON
MOUNTAINS...WHICH SHOULD INCREASE THE CHANCES FOR SNOW SHOWERS IN
THOSE LOCATIONS WITH THE WEAK SYSTEM.

BY THE BEGINNING OF NEXT WEEK...RIDGING GRADUALLY MOVES TOWARD THE
COAST WITH RATHER DRY CONDITIONS PREVAILING ON ALL MODELS ACROSS
THE CWA. HOWEVER...THE EXACT RIDGE PLACEMENT BY THAT JUNCTURE
WILL BE CRITICAL TO TEMPERATURES. THE GFS AND DGEX SOLUTIONS HAVE
A BROADER RIDGE WITH HIGHER HEIGHTS AND LOW LEVEL TEMPERATURES
OVER THE CWA...WHILE THE ECMWF HAS A MUCH SHARPER RIDGE AND
CONTINUOUS NORTHERLY FLOW OVER THE CWA WITH PROGRESSIVE NORTHERLY
DRY FRONTAL PASSAGES DURING THE WEEK. THE RESULT IS A MUCH COLDER
WEEK INDICATED BY THE ECMWF THAN THE GFS...ALTHOUGH NEITHER BRINGS
SIGNIFICANT LIFT OVER THE AREA. AS A RESULT...THE FORECAST TRENDS
RELATIVELY CLOSE TO NORMAL...A BIT COOLER THAN THE GFS...BUT A BIT
WARMER THAN THE ECMWF. /FRIES

&&

.HYDROLOGY DISCUSSION...THE CONCERN FOR URBAN AND SMALL STREAM
FLOODING WILL INCREASE OVERNIGHT INTO TOMORROW MORNING. BREEZY AND
MILD CONDITIONS HAVE CONTINUED TODAY AND WILL PERSIST THROUGH THE
NIGHT. WITH TEMPERATURES EXPECTED TO REMAIN WELL ABOVE
FREEZING...SNOW DENSITIES WILL INCREASE THROUGH THE NIGHT. AS THE
OPEN WAVE TROUGH APPROACHES LATE TONIGHT...MID LEVEL FLOW WILL
BACK TO THE SOUTHWEST...AND THE RAIN SHADOW OVER EASTERN
WASHINGTON WILL BE MUTED. LOOK FOR RAIN TO BUILD BACK INTO THE
SPOKANE METRO...THE NORTHEAST MOUNTAINS...AND INTO THE PALOUSE.
WITH AN ADDITIONAL HALF TO THREE-QUARTERS OF AN INCH OF RAIN LATE
THIS EVENING INTO THURSDAY MORNING...CLOGGED STORM DRAINS AND
WATER OBSTRUCTED BY SNOW BERMS WILL BE A PROBLEM. PONDING IN URBAN
AREAS COULD BE AT ITS PEAK DURING THE MORNING COMMUTE.

THE FLOODING CONCERNS FOR THE COUNTIES SOUTH OF THE PALOUSE LIKE
ASOTIN...GARFIELD...NEZ PERCE...AND LEWIS MAY BE LOW ENOUGH TO
ALLOW FLOOD WARNINGS TO BE CANCELLED EARLY. LOW ELEVATION SNOW
PACK IS CONSIDERABLY LESS IN THESE COUNTIES THAN IT IS AROUND
SPOKANE AND THE NORTHERN VALLEYS. CALLS TO LAW ENFORCEMENT
OFFICIALS AND EMERGENCY MANAGERS WILL BE MADE THIS AFTERNOON. IF
SMALL STREAMS CONTINUE TO RUN LOW THROUGH THE AFTERNOON...IT IS
UNLIKELY THAT THE RAIN EXPECTED TONIGHT INTO TOMORROW WILL BE
SUFFICIENT TO CREATE ANY HYDRO PROBLEMS.

FOR CHELAN AND WESTERN OKANOGAN COUNTIES...MID-LEVEL FLOW HAS
WEAKENED SINCE EARLY THIS MORNING...AND THE SLOP-OVER
PRECIPITATION IS NOT EXTENDING AS FAR EAST. HOWEVER...HEAVY RAIN
WILL CONTINUE ALONG THE CASCADE CREST THROUGH TOMORROW MORNING.
THERE HAS BEEN CONSIDERABLE MELTING OF THE LOW LEVEL SNOW-PACK
DURING THE LAST 12-24 HOURS. WITH THE EXCEPTION OF THE STEHEKIN
RIVER...WE ARE NOT EXPECTING ANY MAIN STEM RIVER PROBLEMS...BUT
SMALL STREAMS AND CREEKS WILL CONTINUE TO RUN HIGH. THE ARRIVAL
OF THE COLD FRONT BETWEEN 12Z AND 18Z WILL HELP TO PUSH SNOW
LEVELS DOWN TO 3000 FEET BY THURSDAY AFTERNOON...AND SNOW-MELT
WILL CURTAIL QUICKLY. /GKOCH

&&

.AVIATION...STRONG UPPER LEVEL FLOW CONTINUES TO PERSIST OVER THE
AREA. RAINSHADOWS WILL ALSO PERSIST IN THE LEE OF THE CASCADES UNTIL
A COLD FRONTAL PASSAGE ON THURSDAY. VERY STRONG FLOW OFF THE SURFACE
WILL ALLOW FOR SOME WIND SHEAR NEAR KPUW AND KCOE AS WELL UNDER THIS
REGIME.  WITH THE FRONTAL PASSAGE AND A STABLE LAYER ALOFT
CHANNELING STRONGER FLOW UNDER IT...STRONG WESTERLY WINDS ARE
POSSIBLE THURSDAY AFTERNOON...ESPECIALLY AROUND KEAT WITH GUSTS OVER
40 KTS POSSIBLE BY AFTERNOON. HOWEVER...OUTSIDE OF PERSISTING RAIN
AREAS...CONDITIONS WILL GENERALLY BE VFR. /FRIES

TO 2 INCHES OVER THE IDAHO PANHANDLE. THIS RUNOFF WILL LEAD TOWARD
AREAS OF FLOODING IN URBAN LOCATIONS...AS WELL AS NEAR SMALL
RIVERS AND STREAMS. SOUTHWEST WINDS OF 20 TO 30 MPH WILL ALSO
REDEVELOP OVERNIGHT...LEADING TOWARD ENHANCED SNOWMELT...ESPECIALLY
OVER THE PALOUSE AND INTO THE SPOKANE AND COEUR DALENE AREA.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

THE CRITICAL PERIOD FOR INCREASING SNOW LOAD HAS PASSED...PEAKING
SOMETIME EARLY WEDNESDAY MORNING...AND SHOULD STABILIZE OR MORE
LIKELY DECREASE FOR MOST LOCATIONS BELOW 4000 FEET MSL AS ABOVE
FREEZING TEMPERATURES...BRISK SOUTHWEST WINDS AND RAINFALL ALLOW
MELTING AND SHEDDING TO OCCUR. MOST ROOFS WITH ANY DEGREE OF PITCH
SHOULD CONTINUE TO SHED SNOW-MELT INTO THURSDAY...FURTHER
DECREASING THE SNOW LOAD. LIQUID RAINFALL AMOUNTS EXPECTED TONIGHT
INTO THURSDAY AFTERNOON WILL RANGE FROM ONE HALF INCH OVER
NORTHEAST WASHINGTON TO ONE INCH NEAR PULLMAN AND MUCH OF THE
IDAHO PANHANDLE.

IT IS IMPORTANT TO NOTE THAT THAT FLAT AND LOW SLOPED ROOFS WILL
CONTINUE TO BE SUSCEPTIBLE TO SNOW LOADS DUE TO THE ACCUMULATION
OF MELT WATER AND POSSIBLE BLOCKAGE HINDERING DRAINAGE.
