EVENT...BEST VORTS AND UPPER LEVEL TROUGHS/COLD AIR NEAR 45N WHILE BEST
JET ALONG 40N...
.
SATELLITE ANALYSIS AND TRENDS...LARGE AREA AFFECTED BY THIS WEST COAST
STORM AS CORE OF 160KTS JET AT 43N/140W NOSING ACROSS N CA NEAR 40N.
LARGE AREAL EXTENT OF RAIN WITH EMBEDDED MODERATE/HVY RAIN ON EITHER
SIDE OF FRONT WHERE JET CROSSES WITH BETTER RAIN ALONG AND NORTH OF THE
JET ALONG FRONT...BUT SOME MODERATES WITH OROGRAPHIC LIFT 38.5N TO 40N
ALONG COAST AND INLAND.  THIS WILL CONTINUE TO BE THE CASE BOTH NORTH
AND SOUTH OF THE JET CROSSING THE FRONT THRU THE AFTERNOON INTO THIS
EVENING AS BACK EDGE STEADY PRECIP PRODUCING CLOUDS ALIGNED WITH HIGHER
PW MOISTURE STILL AT 128/128W AND TROUGH HANGING BACK AT 130/131N.
NOW TO THE NORTH WITH OCCLUSION...LOTS OF LITTLE SWIRLS..AT LEAST 5 BY
MY COUNT...MORE IF YOU HAVE AN IMAGINATION AND BEST LUMPINESS IN VIS
HELPING PRODUCE HEAVIER SHOWERS THAT MICROWAVE WAS INDICATING COULD
BE AS HIGH AS 0.4-0.5”/HR.  THOUGH RAIN AREA SMALLER...SHOWERS MORE
INTENSE AND WHOLE SYSTEM MOVING MUCH SLOWER AND THERE IS DEFORMATION/
DIFFLUENCE THAT IS INFLUENCING THE INSTABILITY.   AS THIS PART OF THE
SYSTEM GETS CLOSER...RAIN WILL INCREASE W WA AND NW OREGON THRU EVENING
AND JUST THE RIGHT OROGRAPHICS COULD ENHANCE EVEN MORE SOUTH FACING
MOUNTAIN AREAS IN THE OLYMPICS AND THEN THE CASCADES.
LOOKS LIKE THIS SYSTEM HAS BROKEN AWAY FROM MORE WELL DEFINED PW
MOISTURE PLUME THAT EXTENDING 150W WEST AND SW...SO ENTRAINED TROPICAL
MOISTURE WILL BE LIFELINE FOR CONTINUING HVY RAIN AS UPPER LEVEL FEATURES
APPROACH AND PW MOISTURE LEFT BEHIND WILL HAVE TO WAIT FOR ANOTHER DAY.
WILL CONTINUE TO MONITOR...
