SATELLITE ANALYSIS AND TRENDS...LATEST BLENDED PW ANALYSIS AND AREA
GPS DATA WAS SHOWING THAT ANOMALOUS MOISTURE CONTINUES OVER PORTIONS OF
THE PAC NW WITH PW VALUES RUNNING OVER 150% ABOVE NORMAL CLIMATOLOGICAL
VALUES.  AREA GPS ARE SHOWING THAT MOISTURE HAS BEEN INCREASING SLIGHTLY
OVER THE PAST DAY FROM PORTIONS OF CNTRL WA EXTENDING S INTO PORTIONS
OF NE/N CNTRL OR.  CURRENTLY THERE WAS A NARROW AXIS OF LOCALIZED HEAVY
SHOWERS WITH ENHANCING CLOUD TOPS JUST S OF YKM.  FURTHER TO THE E, CLOUDS
HAVE CLEARED OVER MUCH OF E WA/SE OR AND GOES SOUNDER WAS INDICATING
THAT BEST DESTABILIZATION WAS OCCURRING OVER SE WA AND NE OR.  IT DOES
APPEAR AS THOUGH MID LEVEL FORCING SHOULD BE BETTER TODAY THAN YESTERDAY
AS WV IMAGERY INDICATES THAT S PORTION OF OFFSHORE SHEAR AXIS/SHORT
WAVE TROF APPEARS TO BE PIVOTING TOWARDS THE OR COAST IN RESPONSE TO
UPSTREAM AMPLIFICATION OF JET STREAK.  12Z RAOBS WERE SHOWING THAT MEAN
WIND PROFILES REMAIN QUITE WEAK WITH SLOW STORM MOTIONS ANTICIPATED
THROUGHOUT THE AFTERNOON.  ALTHOUGH SHEAR WAS WEAK ON MORNING SOUNDINGS,
WEAK HEIGHT FALLS APPROACHING THE OR COAST SHOULD ALLOW FOR A SLIGHT
INCREASE IN LOW LEVEL SHEAR IMPLYING MORE ORGANIZATION THAN YESTERDAY
AND THE  POTENTIAL FOR SOME MULTICELL CLUSTERS TO ENHANCE LOCALIZED HEAVY
RAIN THREAT.  VIS IMAGERY WAS ALSO SUGGESTING A WESTERLY MOVING IMPULSE
OVER S PORTIONS OF ID THAT COULD ALSO HELP TO ENHANCE AN AREA OF MESOSCALE
ASCENT DOWNSTREAM OVER PORTIONS OF OR.  LITTLE INHIBITION REMAINS OVER
PORTIONS OF NE OR AND STARTING TO SEE CU/TCU DEVELOPMENT ON BLUE AND
WALLOWA MOUTNAINS OF NE OR WITH FURTHER DEVELOPMENT LIKELY THROUGHOUT
THE AREA OVER THE NEXT FEW HOURS AS WEAK LARGE SCALE ASCENT CONTINUES
TO COUPLE WITH TERRAIN CIRCULATIONS.  SEE QPFERD FOR MORE DETAILS.
