SATELLITE ANALYSIS AND TRENDS...LATEST WATER VAPOR IMAGERY SHOWS THAT
LARGER SCALE TROF WITH AXIS ALONG 130W CONTINUES TO EVOLVE INTO A NEUTRAL
TO EVEN NEGATIVELY TILTED SYSTEM AS ENERGY CONTINUES TO DIG INTO THE BASE
OF THE SYSTEM.  LEAD SHORTWAVE TROF AND ASSOCIATED VORTICITY LOBE NOW
APPEARS TO BE LIFTING OUT AND IS CURRENTLY LOCATED NEAR NOSE OF DRYING
AROUND 28N/125W.  NEXT VORTICITY CENTER IS LOCATED IN THE BASE OF THE
TROF NEAR 30N/131W AND BELIEVE THIS WILL HELP TO SLOWLY PUSH SYSTEM EAST
THROUGHOUT THE NIGHT BUT BELIEVE THAT ANY FASTER MOVEMENT OF SYSTEM WILL
HAVE TO WAIT FOR LAST SHORTWAVE TROF/JET STREAK NEAR 36N/132W TO ROUND
THE BASE OF THE TROF LATER TONIGHT AND TOMORROW MORNING.
.
FLOW HAS BACKED CONSIDERABLY OVER THE LAST 12 HRS AND EVIDENCE OF
THIS IS NOTED IN THE LATEST AMSU PRECIPITABLE WATER ANALYSIS (2122Z)
AS SYSTEM HAS NOW BEGUN TO TAP INTO SUBTROPICAL MOISTURE RESERVOIR.
IN FACT, AS OF 21Z THE LEADING EDGE OF THE 1.0" PRECIPITABLE WATERS WAS
RUNNING FROM APPROXIMATELY 33N/123W TO NEAR ENSENADA IN THE NORTHERN BAJA.
.
WV IMAGERY SHOWS THAT LARGE SCALE LIFT APPEARS TO BE INCREASING RAPIDLY
SW OF THE CHANNEL ISLANDS AS LEAD SHORTWAVE TROF CONTINUES ITS APPROACH.
THIS SHOULD ALLOW FOR RAINFALL TO INCREASE IN COVERAGE AND INTENSITY
OVER THE NEXT 3-6 HRS FROM APPROXIMATELY SAN LUIS OBISPO SOUTH TO NEAR
SAN DIEGO.  ORIENTATION OF MOISTURE PLUME AND LL WIND FIELD SUGGEST THAT
BEST OROGRAPHIC ASCENT, MOISTURE FLUX AND ASSOCIATED PRECIPITATION SHOULD
BE FOCUSED FROM ALONG THE SAN RAFAEL, SAN GABRIEL AND SAN BERNARDINO
MOUNTAIN RANGES.  WILL CONTINUE TO MONITOR SITUATION THROUGHOUT THE NIGHT.
