EVENT...SHORT BUT POTENT PW PLUME WITH FORCING FOR HVY RAIN GENERATION...
.
SATELLITE ANALYSIS AND TRENDS...INGREDIENTS COMING TOGETHER FOR A HVY
RAIN EVENT NORTHERN CA MOSTLY FROM CAPE MENDOCINO AREA NORTHWARD TO THE
OREGON BORDER.  PW MOISTURE PLUME SETTING UP IN A SW TO NE ORIENTATION
WITH MAX VALUES OF 1.0 INCH EMBEDDED IN PLUME AND APPROACHING NORTHERN CA
THIS AFTERNOON.  AXIS OF HIGHEST MOISTURE HEADING FOR AREA JUST SOUTH OF
CAPE MENDOCINO...SO BELIEVE HIGHEST AMOUNTS OF RAIN WILL FALL FROM NEAR
THE AXIS NORTH TO THE OREGON BORDER REST OF TODAY.  PW ANOMALIES FROM
BLENDED PW PRODUCTS GIVING ANYWHERE FROM 130-150 PERCENT OF NORMAL AND
NOTICED THAT EKA RECORD RAINFALL FOR APR 22 ABOUT 1.46 INCHES.  SO NOT
SURE ABOUT REACHING THAT AMOUNT...BUT COULD BE A GOOD SOAKER FOR THIS
TIME OF YEAR WITH PWS ABOUT 2 STANDARD DEV ABOVE NORMAL ACCORDING TO
SATELLITE PW DATA OFFSHORE.  FIRST WAVE OF HIGH MOISTURE/ENHANCEMENT
COMING IN NOW  AND CAN EXPECT AT LEAST 0.1”-0.2 IN/HR RATES LOW LANDS
AND 0.4”-0.5 IN/HR MOST FAVORED OROGRAPHIC AREAS.  THOUGH MOISTURE
PLUME SHORT AND 700/850MB WINDS PARALLEL THE PLUME FROM 135W EAST TO THE
COAST...DYNAMICS SHOULD MAKE UP FOR THESE DEFICIENCIES TO HELP PRODUCE
THE HVY RAINS MOST OF TODAY.    WILL CONTINUE TO MONITOR...SEE GRAPHICAL
