AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
450 AM PDT THU MAY 26 2011

.SYNOPSIS...
COOLER THAN NORMAL AND UNSETTLED CONDITIONS WILL CONTINUE THROUGH
THE WEEKEND WITH A CHANCE OF AT LEAST MOUNTAIN SHOWERS ALMOST
EVERY DAY. A STRONG WEATHER SYSTEM PASSAGE WILL RESULT IN
WIDESPREAD RAIN AND MOUNTAIN SNOW THROUGH THE MORNING HOURS TODAY
OVER NORTHERN WASHINGTON AND THE IDAHO PANHANDLE. MORE SHOWERS
ARE EXPECTED FRIDAY INTO THE BEGINNING OF NEXT WEEK AS NEARBY LOW
PRESSURE SYSTEMS CONTINUE TO PASS NEAR OR THROUGH THE REGION. THIS
CYCLE WILL EXTEND INTO MID WEEK.

&&

.DISCUSSION...
TODAY AND TONIGHT...AS OF 2 AM...WATER VAPOR SATELLITE INDICATED A
STRONG VORT MAX MOVING ACROSS EASTERN OREGON AND MOVING TOWARDS
CENTRAL IDAHO. STRONG LIFT ON THE NORTH SIDE OF THIS FEATURE WAS
RESULTING IN WIDESPREAD MODERATE TO HEAVY RAIN FROM OMAK TO
RITZVILLE TO THE BLUE MOUNTAINS AND POINT EAST. RADAR TRENDS
INDICATE THAT THIS BAND OF RAIN WILL SLOWLY MOVE ITS WAY NORTHEAST
THROUGH THE MORNING HOURS. IN THE MOUNTAINS...SNOW LEVELS WILL
CONTINUE TO LOWER INTO THE MORNING HOURS AS A STRONG WESTERLY JET
AT 850MB BRINGS COLDER AIR INTO THE AREA. BY SUNRISE...SNOW LEVELS
WILL FALL TO 3000-4000 FEET FROM THE BLUE MOUNTAINS TO THE CENTRAL
PANHANDLE MOUNTAINS. THEN DURING THE EARLY TO MID MORNING HOURS
SNOW LEVELS WILL FALL TO NEAR 4000 FEET FOR THE OKANOGAN HIGHLANDS
EXTENDING EAST TO THE NORTH IDAHO PANHANDLE. MODELS CONTINUE TO
SUGGEST A QUARTER TO A HALF INCH OF QPF AFTER THE COLDER AIR
ARRIVES SO WINTER STORM WARNINGS REMAIN IN PLACE ABOVE 4000 FEET
USING LATE SEASON CRITERIA...WITH 3 TO 5 INCHES EXPECTED.

THEN BY THE AFTERNOON THE ONLY AREAS EXPECTED TO STILL REMAIN WITH
STEADY RAIN/MOUNTAIN SNOW WILL BE FROM COLVILLE TO SANDPOINT AND
POINTS NORTHEAST...WITH PRECIPITATION TAPERING OFF TO
ISOLATED/SCATTERED SHOWERS ELSEWHERE. THEN FOR TONIGHT THE AREA
BECOMES IN BETWEEN FEATURES AS THE SYSTEM THAT COMES THROUGH
TONIGHT MOVES FURTHER AWAY AND THE NEXT WAVE MOVES TOWARDS THE
CASCADES. THUS WHILE SOME SHOWERS WILL LINGER INTO TONIGHT
ESPECIALLY IN THE MOUNTAINS...PRECIP AMOUNTS WILL BE LIGHT.

A TIGHT PRESSURE GRADIENT EXISTS OVER THE AREA THIS MORNING WITH
PDX-GEG PRESSURE GRADIENT AS OF 2 AM AT 13.8MB. MODELS ARE IN GOOD
AGREEMENT THAT THE GRADIENT WILL WEAKEN INTO TODAY AS THE SURFACE
TROUGH OVER WESTERN MONTANA THIS MORNING MOVES EAST. HOWEVER 850MB
WINDS OF 20-25 KTS AND GOOD MIXING POTENTIAL TODAY WILL LEAD TO
BREEZY WINDS INTO THE AFTERNOON.

ADDITIONAL RAINFALL AND SOME SNOW MELT WILL LEAD TO FURTHER RISES
ON AREA RIVERS AND STREAMS OVER THE NEXT COUPLE DAYS. SEVERAL
FLOOD WARNINGS AND WATCHES REMAIN IN EFFECT FOR THE INLAND
NORTHWEST.  JW

FRIDAY THROUGH MEMORIAL DAY...THE FORECAST FOR THE HOLIDAY
WEEKEND REMAINS ESSENTIALLY UNCHANGED AS THE PRESENCE OF A
LONGWAVE TROUGH OVER THE WESTERN CONUS KEEPS TEMPERATURES BELOW
NORMAL WITH POTENTIAL FOR SHOWERS JUST ABOUT EACH DAY. SHOWERS ON
FRIDAY WILL PRIMARILY BE DRIVEN BY ANOTHER WEAK FRONT LIFTING IN
FROM THE SOUTHWEST AS WELL AS CONTINUED UPSLOPING FLOW INTO THE
NORTHERN AND EASTERN MOUNTAINS WITH THE HEAVIER RAINFALL AMTS
FOCUSING ON THE LATTER. BY SATURDAY...ANOTHER CLOSED LOW WILL DROP
INTO THE LONGWAVE TROUGH SINKING THE BASE OF THE TROUGH INTO
SOUTHERN CA AND DRAGGING THE FRONT BACK THROUGH THE REGION FROM
NORTH TO SOUTH. THIS WILL KEEP ABUNDANT CLOUD COVER OVER THE
REGION WITH A CONTINUED THREAT FOR LIGHT SHOWER ACTIVITY. AREAS
WHERE SUN DOES PEAK THROUGH MAY SEE A FEW HEAVIER SHOWERS WITH
AMTS UPWARD NEAR A TENTH. WE WILL BETWEEN SYNOPTIC 500H LOWS ON
SUNDAY UNDER THE PRESENCE OF SHORTWAVE RIDGING. IF THE SFC
DEWPOINTS VIA THE GFS STAND ACCURATE...WHICH ARE FCST TO BE IN THE
MID 40'S TO LOWER 50'S...THE ADDED SOLAR INSOLATION FROM THE WEAK
SUBSIDENCE ALOFT WILL INCREASE THE THREAT FOR AFTN SHWRS WITH
ISOLATED THUNDERSTORMS. THE NAM/SREF ARE BIT MORE BELIEVABLE BUT
STILL HAVE DEWPOINTS IN THE LOWER 40'S...ESPECIALLY ACROSS THE
NORTHERN MTNS. WITH THAT SAID...IT STILL LOOKS PROMISING FOR
ISOLATED TO SCATTERED SHOWERS SUNDAY...ESPECIALLY GIVEN THE
WEAK SUBSIDENCE ALOFT AND BETTER CHANCE FOR A FEW HOURS OF SUNSHINE.

BY MONDAY INTO TUESDAY... ANOTHER DEEP LOW DROPS TOWARD THE COAST
WITH A VORT MAX SWINGING ARND ITS NE QUADRANT LIFTING ANOTHER
FRONT THROUGH THE REGION. E/SE FLOW AHEAD OF THE FRONT WILL FOCUS
THE PRECIPITATION THREAT TOWARD THE CASCADES THEN BEGIN TO SPREAD
TOWARD THE N AND E MONDAY NT AND TUESDAY. THE EC HAS COME IN
BETTER LINE WITH THE GFS/GEM ON THIS IDEA AND POPS REMAIN IN THE
CHANCE CATEGORY WITH ADDITIONAL INCREASES LIKELY AS THE TIMING
BECOMES MORE REFINED. TEMPERATURES OVER THE WEEKEND WILL REMAIN IN
THE UPPER 50'S TO 60'S FOR MOST VALLEYS WITH THE POTENTIAL FOR MID
TO UPPER 60'S...MAYBE LOW 70'S ON MONDAY FOR THE EASTERN TWO-
THIRDS OF THE CWA WHILE CLOUDS THICKEN TOWARD THE CASCADES AND SW
BASIN...VERY SIMILAR TO THIS PAST WEDNESDAY.

TUESDAY NT THROUGH FRIDAY...THE UPPER-LEVEL TROUGH WILL REMAIN
STATIONARY OVER THE WEST KEEPING THE COOL...UNSETTLED PATTERN
ONGOING. GEM/GEFS/GFS KEEP THE CENTER OF THE TROUGH OVER THE
INLAND NW WHILE THE EC IS A TOUCH OFF THE COAST...LEANING TOWARD
A WARMER SOUTHERLY FLOW REGIME. GIVEN THE UNCERTAINTY AND BACK N
FORTH OF EACH MODEL RUN...WILL HOLD OFF ON MAJOR CHANGES BUT BEGIN
TO SHOW A FEW DEGREES OF WARMING AND SLIGHT DECREASE IN POPS
TOWARD CLIMO. /SB

&&

.AVIATION...
12Z TAFS...A BAND OF RAIN IMPACTING AREAS EAST OF A LINE FROM OMAK
TO PULLMAN WILL GRADUALLY MOVE NORTHEAST THROUGH THE MORNING.  THIS
WILL KEEP IFR AND MVFR CONDITIONS PERSISTING AT
KGEG/KSFF/KCOE/KPUW/KLWS THROUGH MOST OF THE MORNING WITH THE
QUICKEST IMPROVEMENT EXPECTED AT KPUW AS DRIER AIR FROM THE TRI
CITES MOVES EAST INTO THE AREA.  A TIGHT PRESSURE GRADIENT WILL LEAD
TO GUSTY WINDS THROUGH 03Z THIS EVENING.  FOR KMWH/KEAT...DRIER AIR
HAS ALREADY MOVED INTO THE AREA WITH VFR CONDITIONS EXPECTED TO
CONTINUE THROUGH 12Z FRIDAY.  JW
