SATELLITE ANALYSIS AND TRENDS...1509Z SSMI PASS SHOWING NOSE OF 1.2" PW
ABOUT 225 MILES OFF THE N CA COAST AND 1.0"-1.1" ALREADY ALONG THE COAST
WITH HIGHEST AREAL AVERAGE RAIN RATE OF .13"/HR ASSOCIATED WITH COLD TOPS
SEEN IN IR IMAGERY JUST MAKING THEIR WAY ONSHORE NEAR THE OR/CA BORDER.
THESE TOPS HAVE COOLED SOME BUT HAVE EXPANDED A GOOD AMOUNT SINCE THAT
PASS AND SHOULD BE MOVING INTO THE OR/CA COAST WITHIN THE NEXT HOUR.
IR IMAGERY SHOWING AREA OF ENHANCED TOPS STRETCHING FROM AREA MENTIONED
ABOVE SW TO APPROX 38N/133W ASSOCIATED WITH SHORTWAVE APPARENT IN
WV IMAGERY PLUS GOES WINDS SHOWING 140KT JET.  EXPECTING THIS ENERGY
TO CONTINUE TO MOVE EWD AND ROTATE AROUND THE MAIN UPPER LOW TO THE N
BRINGING IN MOD/HVY RAINS FOR THE REMAINDER OF THE AFTERNOON AND EVENING.
WITH GOOD 1.25"+ PW PLUME AVAILABLE...EXPECTING THE TERRAIN FAVORED
AREAS TO SEE FREQUENT PERIODS OF VERY HEAVY RAINS DURING THE NEXT 6-12
HOURS WITH ANY REMNANT SNOW MELTING ALONG WITH THE RAIN.
FURTHER OUT THE 1.25"-1.5" CORE MOISTURE PLUME STRETCHES PAST 180W
WITH GOES WINDS SHOWING CORE 100+ KT JET STRETCHING OUT TO ABOUT
180W-175E  BETWEEN THE LARGE HIGH AND POW PRESSURE SYSTEMS.  ANOTHER WELL
DEFINED SHORTWAVE AND AROUND 35N/165W AND CLOSED LOW CLOSED LOW AROUND
37N/170W IS AIMING TO BE THE NEXT BIG RAIN MAKER FOR THIS WHOLE EVENT.
WHILE THE RAINS SHOULD SUBSIDE SOMEWHAT BETWEEN THE CURRENT AND NEXT
SHORTWAVE...EXPECTING FAVORABLE W/SWRLY FLOW TO CONTINUE AND KEEP THE
THREAT FOR ORAGRAPHICALLY ENHANCED PRECIP IN THAT TIME PERIOD.
