EVENT...NEXT COLDER SYSTEM FOR THE WEST COAST...STRONGER WAVE 41N INSIDE

.
SATELLITE ANALYSIS AND TRENDS...TREND FROM GOES...MICROWAVE AND
SCATTEROMETER WINDS OFFSHORE WOULD SUGGEST A SLIGHTLY DEEPER SURFACE WAVE
AT 41N/137W ON FRONT FROM PARENT LOW CLOSE TO 44N/130W.  THIS FURTHER
CONFIRMED WITH PW MOIST GRADIENT THAT HAS BEEN GLIDING ESE AND NOW
WAS IN THE VIC OF THIS WAVE.  CONTRAST IS 1.1" PW VALUES AT 39N/137W
AND DRY ADVECTION AS CLOSE 43N/140W WITH PW VALUES CLOSE TO 0.40".
IT IS THIS CONTRAST PW MOISTURE OVER A RELATIVE SHORT DISTANCE  ALONG
WITH HIGH LEVEL SATELLITE WINDS OF 100KTS (45N/160W TO 42N/143W COMING
IN BEHIND THAT SHOULD HELP THIS SURFACE WAVE HOLD TOGETHER AND MAY BE
EVEN DEEPEN BEFORE REACHING THE OREGON COAST DURING THE DAY MONDAY.
IN ANY CASE ENHANCED CLOUDS OUT AHEAD XTRAPOLATED TO BRING MOSTLY LIGHT
TO MODERATE RAIN TO N CA/SW TO C OREGON COAST AS EARLY AS 10Z  WITH THAT
SOUTHERN WAVE NOW 41N/137W APPROACHING THE COAST VIA XTRAPOLATION IN
THE 19-22Z TIME PERIOD.  AND ACCORDING TO EXPERIMENTAL AMSU THICKNESS
PRODUCT...PASSAGE OF THAT SOUTHERN WAVE REALLY BEGINS TO BRING IN MUCH
COLDER AIR ALOFT TO S OREGON AND N CA.   WILL CONTINUE TO MONITOR...
