AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
430 PM PDT THU JUN 9 2011

.SYNOPSIS...
A WEAK STORM SYSTEM WILL SLIDE ACROSS THE REGION ON FRIDAY BRINGING
SCATTERED SHOWERS AND A FEW THUNDERSTORMS. ANOTHER ROUND OF MAINLY
AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS WILL LIKELY OCCUR
ON SATURDAY. A WEAK BUT PROGRESSIVE STORM TRACK WILL KEEP TEMPERATURES
NEAR NORMAL THROUGH THE NEXT WEEK...WITH SHOWERS MAINLY CONFINED
TO THE MOUNTAINS NORTH AND EAST OF THE COLUMBIA BASIN. MONDAY WILL
BE THE NEXT BEST CHANCE FOR RAIN.

&&

.DISCUSSION...

TONIGHT...A SHORTWAVE RIDGE OF HIGH PRESSURE CURRENTLY CENTERED
ALONG THE SPINE OF THE CASCADES WILL CONTINUE TO DRIFT INTO
EASTERN WA AND NORTHERN IDAHO BRINGING CLEARING SKIES AND ABRUPT
END TO ANY LINGERING SHOWERS. THE CLEARING WILL PROMOTE ANOTHER
NIGHT OF STRONG RADIATIONAL COOLING AND POTENTIAL FOR FOG IN THE
NORTHERN VALLEYS. DUE TO THE LACK OF RAINFALL TODAY COMPARED TO
WEDNESDAY...FOG COVERAGE WILL BE LESS WIDESPREAD BUT STILL MAY
CAUSE SOME TRAVEL PROBLEMS FOR THE FRIDAY MORNING COMMUTE ACROSS
THE NORTHERN VALLEYS. AS THE RIDGE AXIS SLIDES EAST...MID AND HIGH
CLOUDS WILL BEGIN TO MOVE INTO THE CASCADES AND WESTERN BASIN
AHEAD OF THE NEXT...WEAKENING FRONTAL SYSTEM SET TO ARRIVE ON
FRIDAY. /SB

FRIDAY THROUGH SATURDAY NIGHT...AN UPPER LEVEL TROUGH WILL SETTLE
INTO THE INLAND NORTHWEST RESULTING IN A PERIOD OF SLIGHTLY BELOW
NORMAL TEMPERATURES AND SHOWERY CONDITIONS. THE BULK OF THE
SHOWERS WILL OCCUR DURING THE AFTERNOON AND EVENING HOURS WHEN THE
ATMOSPHERE IS THE MOST UNSTABLE. THERE WILL ALSO BE A SERIES OF
UPPER LEVEL DISTURBANCES PASSING THROUGH PROVIDING EXTRA LIFT.
WESTERLY FLOW WILL KEEP THE BULK OF THE SHOWERS OVER THE HIGHER
TERRAIN OF NORTHEAST WASHINGTON AND NORTH IDAHO...WITH JUST A
SLIGHT CHANCE OF SHOWERS IN THE COLUMBIA BASIN. FOR FRIDAY AND
SATURDAY DURING THE AFTERNOON AND EVENING HOURS THE GFS SHOWS
LAPSE RATES OF 7-7.5 C/KM AND UNCAPPED CAPES OF 200-500 J/KG OVER
EASTERN WASHINGTON AND NORTH IDAHO. THIS WILL RESULT IN SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS OVER THE AREA. /JW

FOR SUNDAY THROUGH THURSDAY...THE INLAND NW WILL REMAIN UNDERNEATH
WEAK ZONAL FLOW NEXT WEEK WITH NEAR NORMAL TEMPERATURES EXPECTED.
MAINLY MINOR SHORTWAVE TROUGHS WILL PERIODICALLY PASS BRINGING
ISOLATED TO SCATTERED MOUNTAIN SHOWERS TO THE REGION. MOST OF
THESE WEAK SHORTWAVE TROUGHS WILL BE SLIDING TO OUR NORTH SO RAIN
CHANCES WILL BE HIGHEST NEAR THE CANADIAN BORDER MOST DAYS.
HOWEVER...THE NEWEST EC MODEL IS DEEPER AND MORE VIGOROUS WITH A
SHORTWAVE TROUGH ON MONDAY SO POPS MAY BE SOMEWHAT UNDERDONE
DURING THIS PERIOD. BOTH THE GFS AND EC BRING A STRONG UPPER LEVEL
CLOSED LOW PRESSURE ACROSS THE REGION NEXT THURSDAY...BUT GIVEN
THE TIME BETWEEN NOW AND THEN...CONFIDENCE IS STILL FAIRLY LOW.
/NEUMAN

&&

.AVIATION...
00Z TAFS...EXPECT THE ONGOING SHALLOW CUMULUS FIELD TO DISSIPATE
QUICKLY THIS EVENING LEADING TO BRIEF SKC SKIES OVERNIGHT. GIVEN THE
LACK OF RAIN TODAY...FOG SHOULD BE MUCH LESS WIDESPREAD THAN LAST
NIGHT AND LARGELY CONFINED TO THE MOST SHELTERED VALLEYS OF
NORTHEAST WA AND NORTH IDAHO. BCFG WAS REMOVED FROM KSFF GIVEN THEIR
CURRENT DEWPOINT AND FORECASTED LOW TEMPERATURE. A WEAK FRONT WILL
PUSH ACROSS THE REGION ON FRIDAY BRINGING AN INCREASE IN CLOUD COVER
AND A CHANCE OF RAIN SHOWERS AND ISOLATED THUNDERSTORMS TO THE
EASTERN TAF SITES. /NEUMAN
