SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 04/23/14 2040Z
SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404
LATEST DATA USED: GOES-15 2030Z KUSSELSON
NOAA AMSU: 1600 1738Z 1852Z DMSP SSMIS:1632Z 1814Z
.
LOCATION...OREGON...WASHINGTON...NW CALIFORNIA
.
ATTN WFOS...PDT...SEW...PQR...MFR...EKA...
ATTN RFCS...NWRFC...
.
EVENT...NOT OVERLY IMPRESSIVE FORCING, JET, MOISTURE AND MOISTURE
TRANSPORT..BUT SOME ENTRAINED SUBTROPICAL MOISTURE AND SERIES OF PV
CENTERS THAT CAN STILL MAKE FOR A 1"+ SYSTEM...
.
SATELLITE ANALYSIS AND TRENDS...RAIN RATES OFFSHORE WITH UPCOMING SYSTEM
NOT ALL THAT IMPRESSIVE ON MORNING MICROWAVE PASSES...BUT AREA EXTENT AND
FETCH EXTENDING SOUTHWEST ALONG WITH OROGRAPHIC FLOW WILL PROBABLY MAKE
UP FOR THE LACK OF SIGNIFICANT RAIN RATE VALUES.   LONG BLENDED TPW LOOP
GOING BACK A WEEK SHOWED THAT THIS INCOMING SYSTEM HAD ENTRAINED SOME
MOISTURE THAT HAD LIFTED NORTH AND NE AWAY FROM TROPICAL DISTURBANCE 98W
WHEN IT WAS EAST OF THE PHILIPPINES.  NOT A WHOLE LOT GOT ENTRAINED...BUT
ENOUGH THAT IT HAS CARRIED EAST INTO THE EASTERN PACIFIC SINCE APRIL
19/20.
AND JUST A LITTLE WITH GOOD DYNAMICS CAN RESULT IN LOCALLY HVY RAINS,
ESPECIALLY MOUNTAINS/HILLS AS IT PENETRATES THE COAST LIKE WHAT IS GOING
ON NOW CENTERED NW OREGON AND SW WA EAST TO THE CASCADES.  ON PWAT LOOP,
WARM FRONTAL MOISTURE WELL DETECTED AHEAD OF FRONT ORIENTED SSW TO NNE
AND DRIFTING EAST-NE TOWARD WESTERN OREGON AND SW TO WEST CENTRAL WA
WITH MAX VALUES OF 1.1".  GOOD ENOUGH FOR RAIN PRODUCTION AND EQUALLY
MOISTENING UP THE ATMOSPHERE CENTERED ON WESTERN AND NORTHERN OREGON AND
SOUTHERN WA AND INCREASING NORTH AS WARM FRONT APPROACHES.  SIZING UP
TRIPLE POINT NEAR 45N/130W AND WARM FRONT EXTENDING SOUTHEAST TOWARD
THE SW OREGON/NW CA BORDER AREA. MOST IMPRESSIVE IS THE EFFECTS OF THE
VARIOUS FRONTS AND THEIR MOISTURE IDENTITIES AND JET INTERACTION WITH
MOISTURE FROM FRONT NEAR 40N/140W TO 45N/130W TO THE S TO C OREGON COAST.
A BIT OF A DISAPPOINTMENT WAS MOISTURE TRANSPORT WINDS AT 700-800MB THAT
WERE BLOWING PARALLEL THE HIGHEST MOISTURE ONLY FOR A SHORT STRETCH FROM
40N/135W INTO OREGON AND
SW WA...SO MAYBE THE OTHER ASPECTS WILL MAKE UP FOR THIS LACKING ASPECT,
AT LEAST FOR NOW.    SYSTEM DID HAVE STEADY EAST/NE MOVEMENT TO BACK
EDGE OF MOISTURE/DRIER AIR OF ABOUT 575 MILES IN THE PAST 12HRS...SO THIS
SHOULD BE A RELATIVE QUICK SYSTEM FOR STEADY PRECIP...BUT QUITE LINGERING
SHOWERS BEHIND AS THURSDAY GOING ON ESPECIALLY WEST OF THE CASCADES.
AND A SYSTEM THAT CAN EASILY GIVE 24HR TOTALS OF OVER AN INCH, ESPECIALLY
OROGRAPHIC AREAS FROM FAR NW CA NORTH THRU THE CASCADES...EVEN 2-3 INCHES
ISOLATED SPOTS IF EVERYTHING CAME TOGETHER AND TRANSPORT GOT A BIT BETTER
TO GO ALONG WITH ANY ENTRAINED SUBTROPICAL MOISTURE.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 2030-0300Z...MEDIUM TO HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...MAX PRECIP WITH WARM FRONT NW CA THRU WESTERN
WA INTO SW WA AND OREGON CASCADES INCREASING AT LEAST S WA CASCADES.
THEN FRONTAL SYSTEM INFLUENCES AFTER THIS PERIOD FOR MORE STEADY RAINFALL.
