SATELLITE ANALYSIS AND TRENDS...NOSE OF STG JET CORE NOW JUST OFF THE
NW OR COAST. SATELLITE DERIVED WINDS OF 160+ KT NR 45N145W. N OF THE
JET AXIX (ALG 45N) A QUICK SHOT OF MDT/HVY RAIN WILL BE CROSSING THE
COAST NEXT 6 HRS AND THEN RETURN TO MORE SHOWERY REGIME IN ONSHORE
FLOW. SSMI/AMSU MICROWAVE DERIVED INSTANTANEOUS RAIN RATES FROM 12-15Z
WERE GIVING MAINLY .10-.15"/HR RATES WITH THE FTR NOW ALG 125W. THERE
HAS BEEN SOME ENHANCEMENT IN GOES IMAGERY SINCE THEN SO RATES ARE LIKELY
A BIT HIGHER. AND OROGRAPHIC LIFT WILL ALSO ENHANCE RATES. LATEST TRENDS
SUGGEST HEAVIEST RAIN FROM CLATSOP TO GRAYS HARBOR COUNTIES.
.
BEST MOISTURE IS LINED UP A BIT S OF JET AXIS AND IS ALIGNED E/W ALG
40N WITH BULK OF HIGHEST VALUES IN PLUME W OF 130W. 1" VALUES HAVE
REACHED REACHED 130W WITH HIGHEST VALUES OF 135" BTWN 135-145W. THUS
AFTER QUICK SHOT OF MDT/HVY RAIN UP THE COAST IN NW OR INTO CENTRAL
WA FEEL THAT HEAVIEST RAIN WILL SETTLE FURTHER DOWN THE COAST INTO SW
OR/NW CA (ROUGHLY HUMBOLDT TO DOUGLAS COUNTIES) LATER THIS AFTN INTO
THE OVERNIGHT. EXPECT THIS AREA TO BE IN A LONGER LASTING RAIN EVENT.
