SATELLITE ANALYSIS AND TRENDS...INTENSE UPPER LOW WRAPPING NWD TWDS
VANCOUVER ISLAND IS CENTERED AT 45.5N/128 W CURRENTLY. 1805Z AMSU PASS
ALONG WITH GOES SOUNDER/GPS VALUES INDICATE 1.2-1.4" MAX PW VALUES STILL
ASSCD WITH THE LOW LVL MOISTURE PLUME THAT CONTINUES TO SINK SEWD AND
SLIDE INLAND ACROSS THE SIERRAS. 21Z STLT WINDS INDICATE THE UPPER LVL
JET AXIS IS LINED UP FAIRLY WELL WITH THE DARK/DRIER AIR SEEN ON WV
IMAGERY S OF THE UPPER LOW AND ENTERING NW CA..THOUGH DOES SEEM TO BE
SHIFTED A LITTLE FARTHER INLAND NEAR THE CA/NV BORDER THAN WV IMAGERY
DEPICTS. STRONG UPPER LVL DVG IS SEEN ACROSS CENTRAL CA ENHANCING THE
LOW LVL MOISTURE PLUME THAT MUCH MORE AS IT IS ALIGNED WITH THE WRN EDGE
OF THE PW PLUME. AMSU/TRMM PASSES MISSED THE ERN PARTS OF CENTRAL CA BUT
SHOW AREAL AVG MICROWAVE RAIN RATES OF .1-.2"/HR STILL ALONG THE COAST
AND OFFSHORE. THESE RATES ARE BEING ENHANCED BY THE FAVORED TOPOGRAPHY
OF CA BUT HAVE LESSENED SLIGHTLY FROM THE PREVIOUSLY SEEN .25-.3"/HR
AREAL AVG RATES EARLIER IN THE DAY. TWO SUBTLE S/WVS SEEN ON WV OFF THE
COAST SHOULD HELP TO PRODUCE SLIGHTLY HEAVIER PRECIP RATES AS THEY COME
ASHORE..ONE IS JUST STARTING TO COME ASHORE INVOF THE NRN BAY AREA WHILE
ANOTHER IS CENTERED AT 40N/140W.
.
LATEST IR IMAGERY SHOWS COOLING CLOUD TOPS BETWEEN KMRY AND THE BAY
AREA..BOTH OVERLAND AND OFFSHORE THAT IS WITHIN THE WRN EDGE OF PW PLUME
AND HAS BEST UPPER LVL DVG/LOW LVL MOISTURE CNVG COLOCATED. ALONG WITH
ANOTHER AREA OF HVY PRECIP TO THE SE/E THAT IS PROBABLY CHANGING OVER TO
SNOW AT HIGHER ELEV OF THE CENTRAL AND POSSIBLY SRN SIERRAS..THIS RAINFALL
WILL CONTINUE TO SOAK CENTRAL CA AS IT MOVES SEWD. WITH THE PASSAGE OF
THE COLD FRNT IN N CA..WILL SEE LOWERING SNOW LVLS IN THE MTNS..KBLU
JUST CHANGED OVER TO S+ AT 23Z ALONG WITH KTVL BACK TO SNOW. SEE WEB
ADDRESS IN ABOUT 10-15 MIN FOR GRAPHIC.
