SATELLITE ANALYSIS AND TRENDS...NEXT SHORTWAVE IS SEEN ON WV IMAGERY
MOVING EWD JUST S OF THE ERN ALEUTIANS. ALREADY IT IS BEGINNING TO CLOSE
OFF INTO AN UPPER LVL CIRCULATION AND SHOULD CONTINUE TO DO SO OVER THE
NEXT 12 HRS AS IT ENTERS THE GULF OF ALASKA. WAVE OF MOISTURE IS SEEN SE
OF CIRCULATION PER WV IMAGERY/LATEST POLAR DATA WITH THE APEX OF THE WAVE
INVOF 45N/140W. LARGEST POOL OF OVER 1" PW VALUES IS CURRENTLY SINKING
SWD OFF THE CA COAST AND SHOULD EVENTUALLY GET CUT OFF AS THE S/WV
REDIRECTS THE THINNING MOISTURE PLUME LEFT ACROSS THE E PAC BACK INTO
OR/N CA. PLUME IS RATHER LONG STRETCHING FROM THE DATELINE BUT IS VERY
THIN AT THIS TIME AND S/WV IS NOT NEARLY STRONG ENOUGH TO PULL THE DEEP
TROPICAL MOISTURE NEEDED FOR A BIG RAIN EVENT. STLT WINDS SHOW A STRONG
160KT JET WITH EMBEDDED CORES UP TO 180KTS TRYING TO PUSH SOME MOISTURE
OVER THE E PAC RIDGE THAT IS CURRENTLY IN PLACE. PW VALUES OF 1-1.25" ARE
SEEN ROUNDING THE TOP OF THE RIDGE AND WITHIN THE PLUME WHICH WILL ALLOW
FOR THE ONSHORE FLOW PRECIP TO CONTINUE IN WRN WA/WRN OR/AND NRN CA FOR
THE NEXT 12-24 HRS AND MOST LIKELY THROUGH MUCH OF THE WEEKEND. EXPECT AN
INCREASE IN PRECIP RATES..PARTICULARLY OVER W OR/N CA AS WAVE OF MOISTURE
APPROACHES THE COAST IN THE 03-06Z TIMEFRAME. WILL CONTINUE TO MONITOR.
