SATELLITE ANALYSIS AND TRENDS...BEFORE GETTING TO THE NEXT SYSTEM TO
AFFECT THE NORTHWEST ON THURSDAY...INTERESTING STRAIT OF JUAN DE FUCA
FOCUSED NARROW PLUME THAT APPARENTLY IS HELPING TO ENHANCE SNOW BAND
ACROSS SNOHOMISH COUNTY AND SAME DEAL BUT WEAKER GOING ON OFF STRAIT OF
GEORGIA INTO WHATCOM COUNTY...BUT THAT MUCH WEAKER.
NOW THE NEXT SYSTEM...MICROWAVE DATA SHOWING PRECIPITATION TRENDS AND
MOVEMENT OFFSHORE SHOWED LEADING EDGE OF PRECIP ABOUT 24HRS AGO JUST
GETTING PAST 160W.  AT 12Z THE LEADING WAS JUST PAST 150W.  LATEST AMSU
1923Z PASS HAD LEADING EDGE OF RAIN TO 43N/145W TO 51N/141W.  SO THAT
LEADING EDGE APPEARS TO TRACKING FASTER AND RAIN RATES HOLDING THERE OWN
AT GENERAL 0.05" TO 0.15"/HR WITH MAX RATES TO AROUND 0.20"/HR...POSSIBLY
SLIGHTLY HIGHER IN A FEW SPOTS.  LATEST MICROWAVE DATA ACTUALLY HAD
SLIGHTLY HIGHER RATES CLOSE TO THE FRONT PART OF THE RAIN AREA.  NOT SURE
THAT WILL CONTINUE...BUT GIVES AN INDICATION THAT LOTS OF SUBTROPICAL
MOISTURE GETTING INVOLVED...NOT THE FOCUSED ONE SHOT SUBTROPICAL MOISTURE
WE SAW GET INVOLVED WITH LAST SYSTEM.  SO THIS SUBTROPICAL MOISTURE
APPEARS TO BE STEADY AND SHOULD CONTINUE TO GET PUMPED IN AS LEADING
EDGE OF RAIN GETS CLOSER.  ALSO THIS NEXT SYSTEM ON WATER VAPOR HAS MAIN
CENTER GOING FURTHER WEST AND NORTH THAN PREVIOUS BUT THIS NEXT SYSTEM
HAS A LONGER FETCH OF JET AND SHORT WAVES IN HIGH LEVEL FLOW THAT COULD
SUSTAIN BETTER THE HEALTHY PRECIP DEPICTED IN THE MICROWAVE IMAGERY.
ALL THINGS ARE RELATIVE AND AMSU MAX PWS AT 45N WERE ONLY 1.25" AND 1.4"
AT 40N...MOIST PLUME LARGER THAN LAST AND SEEMS TO HAVE MORE STAYING
POWER...WE WILL SEE.  AND MORE IMPORTANTLY 700/850MB WINDS WERE BLOWING
PARALLEL THE PLUME FROM 35N/165W TO NOSE OF THE PLUME AT 46N/141W AND
THIS TRANSLATING INTO VERY GOOD MOISTURE TRANSPORT OR REPLACEMENT OF
PRECIP FALLING OUT OF THOSE LEADING EDGE PRECIP CLOUDS.  EXPERIMENTAL
CIRA/COLO STATE AMSU THICKNESS LOOP DID SHOW CRITCAL RAIN/SNOW LINE HAD
GOTTEN AS FAR NORTH AS 45-46N WITH FRONT...BUT THAT IS WHERE IT PEAKED
SHARPLY BEFORE DROPPING PRETTY QUICKLY BEHIND THIS FRONT WITH NEXT SYSTEM.
AND ALSO ALL IMPORTANT PW ANOMALIES WITH NEXT SYSTEM HAD MORE 200 PERCENT
OF NORMAL WITH THE PLUME THAN PREVIOUS SYSTEM THAT CAME IN YESTERDAY.
WILL CONTINUE TO MONITOR AND SEND MESSAGES.
