SATELLITE ANALYSIS AND TRENDS...WV IMAGERY SHOWS UPPER LOW SLOWLY
MIGRATING EWD IN THE N PAC TWDS BRITISH COLUMBIA. WELL DEFINED JET SEEN
WITH DRIER AIR WRAPPING AROUND THE SRN SIDE OF THIS LOW..2237Z GOES STLT
WINDS SHOW A 150 KT JET STRETCHING FROM LONGITUDE 152 DEG TO 134 DEG
WITH A 160 KT MAX SEEN JUST BEHIND THE FRNT. LATEST MICROWAVE PASSES
HAVE SHOWN A FAIRLY STRONG CONNECTION TO TROPICAL MOISTURE ORIGINATING
FROM NEAR 28N/170W. PW PLUME IS MOSTLY COMPOSED OF 1.4-1.6" PW VALUES BUT
AN INCREASE IN LOW LVL MOISTURE IS NOTICED IN THE PLUME FROM 37N/140W TO
42N/130W WITH VALUES FROM 1.6-1.8" INVOF A WAVE ALONG THE PLUME. S/WV SEEN
ON WV IMAGERY IS IN ABOUT THE SAME SPOT AS THE PW WAVE SO THIS ALONG WITH
ENHANCEMENT FROM THE STRONG JET IS LIKELY THE REASON FOR THE HIGHER PW
VALUES. HIGHEST AREAL AVG. RAINRATES FOUND BY THE SSMI/AMSU SENSORS WERE
ONLY BETWEEN .2-.3"/HR AND THIS WAS ONLY IN ONE OR TWO PIXELS..FOR THE
MOST PART RATES HAVE NOT INTENSIFIED YET. THESE SHOULD INCREASE THOUGH
ONCE ORAGRAPHICS ARE FIGURED IN AND ALSO WITH MORE INTERACTION FROM THE
JET. LAST FEW VIS IMAGES PRIOR TO DARKNESS SHOWED CELLS WITH TOPS GROWING
ABOVE THE STRATUS DECK AND COOLER CLOUD TOPS ARE NOW SEEN ON IR IMAGERY
AS WELL. MODEL OUTPUT IS IN AGREEMENT WITH A LARGE AMOUNT OF RAIN ON
THE COAST OF N CA AND OR OVERNIGHT BUT THIS IS ONLY THE FIRST REAL BIG
RAIN EVENT OF THE SEASON FOR THE AREA. WILL CONTINUE TO MONITOR. SEE
WEB GRAPHIC IN ABOUT 5-10 MIN AT ADDRESS BELOW.
