EVENT...SHORT WAVE NOW MOVING ONSHORE OVER SW OREGON AND NORTHWEST
CALIFORNIA
.
SATELLITE ANALYSIS AND TRENDS...TROF HAS BEEN DIGGING PAST 6 HRS AS
IT APPROACHED AND IS NOW CROSSING THE COAST. TROF AXIS IS NOW ALG 130W
WITH BASE DARKENING IN WV IMAGERY NOW DOWN TO 37N. THIS AMPLIFICATION
IS QUICKLY PROPELLING MAIN PW MOISTURE PLUME SWRD ALG THE CA COAST AND
THEREFORE LIMITING RAINFALL AMNTS. HOWEVER..FAST MVG VORT CENTERED JUST
OFF THE SW OR COAST HAS JUST RECENTLY TAPPED INTO PW PLUME MOISTURE
AND WITH ENHANCED UPPER DIFFLUENCE THIS HAS ALLOWED FOR ENHANCEMENT
OF CLD TOPS ASCD WITH SHOWERS CROSSING HUMBOLDT..DEL NORTE...CURRY AND
ADKACENT COUNTIES. EARLIER AMSU MICROWAVE DERIVED RAIN RATES FROM 1330Z
WERE INDICATING MAINLY .1-.2"/HR RATES. WITH CLD TOP ENHANCEMENT SINCE
THAT TIME IN GOES IMAGERY EXPECT THAT RATES ARE A BIT HIGHER NOW. BUT
FAST MVMNT WILL ENSURE A QUICK BURST OF MDT/HVY RAINFALL AS THE SHOWERS
MV THRU. RAIN RATES FURTHER S ASCD WITH THE PW PLUME MAX WERE MAINLY IN
THE .10-.15"/HR RANGE.
.
QUICKLY LOOKING AT NEXT SYSTEM OUT NR 160W..THIS IS A WETTER SYSTEM ATTM
THAN THE ONE CURRENTLY CROSSING THE COAST...ALTHO THE PLUME HAS NARROWED
AND PW VALUES HAVE SLIGHTLY DCRD PAST 12 HRS OR SO. EXPECT THIS TREND
TO CONTINUE AS THE SYSTEM MOVES E AND PW PLUME BECOMES FURTHER REMOVED
FROM ITS SUBTROPICAL SOURCE RGN. RAIN RATES ARE ALSO HIGHER BUT WILL BE
WATCHING THIS SYSTEM CLOSELY AS IT APPROACHES THE COAST.
