.
SATELLITE ANALYSIS AND TRENDS...MOST RECENT WATER VAPOR IMAGERY CONTINUES
TO SHOW A POSITIVELY TILTED TROF AXIS FROM UPPER LOW CENTER NEAR 28N/164W
EXTENDING TO NEAR 16N/169W.  TO THE EAST OF THIS SYSTEM AN ANTICYLONICALLY
CURVED SUBTROPICAL JET STREAK ARCED FROM 20N/160W TO 20N/130W.  SEVERAL
SUBTLE IMPULSES APPEARED TO BE LIFTING NE IN THE SUBTROPICAL STREAM OF
MOISTURE WHICH WAS HELPING IN DESTABILIZATION OVER MOSTLY THE BIG ISLAND.
IT APPEARS AS THOUGH THE FIRST IMPULSE HAS LIFTED NE OF THE BIG ISLAND
OVER THE LAST COUPLE OF HOURS BUT THERE DOES APPEAR TO BE ANOTHER WEAK
IMPULSE IN THE VIC OF 19N/158W THAT SHOULD MOVE BACK OVER THE ISLAND
OVER THE NEXT 3-6 HRS.
.
NOAA AMSU PRECIPITABLE WATER ANALYSIS (2333-0355Z) SHOWS THAT SLIGHTLY
VEERED LOW LEVEL WINDS CONTINUE TO TRANSPORT DEEP SUBTROPICAL MOISTURE
FROM THE SE INTO MOSTLY THE EASTERN ISLANDS.  A SECOND PLUME OF HIGHER
PRECIPITABLE WATERS WAS NOTED FROM OAHU/KAUAI EXTENDING TO 20N/170W.
MAXIMUM PW'S WERE GENERALLY RANGING FROM 1.60-1.80" AND WERE MOSTLY
CONFINED ALONG AND TO THE EAST OF THE BIG ISLAND.  PRESENT TRENDS WOULD
SUGGEST THAT DEEPEST MOISTURE SHOULD CONTINUE BEING ADVECTED WNW THROUGH
THE DAY AND ENCOMPASS MOST OF THE ISLAND CHAIN BY AFTERNOON.  BELIEVE AT
LEAST A LOCALIZED HEAVY RAIN THREAT WILL ENCOMPASS THE WINDWARD SIDE OF
ALL THE ISLANDS TODAY WITH THE TRANSPORT OF DEEP MOISTURE INTO THE AREA.
THREAT SHOULD PROBABLY BE A LITTLE HIGHER ON THE WINDWARD SIDE OF THE
BIG ISLAND WITH FAVORABLE ORIENTATION OF UL JET STREAK.
.
IT DOES APPEAR AS THOUGH WEAK UPPER LEVEL LOW NEAR 28N/164W HAS WOBBLED
SLIGHTLY NORTHEAST OVER THE PAST FEW HOURS AND THIS TREND SHOULD CONTINUE
AHEAD OF HEIGHT FALLS NOW CROSSING THE DATE LINE.  UPSTREAM SYSTEM DOES
NOT APPEAR TO BE AMPLIFIED ENOUGH FOR HEIGHT FALLS SOUTH OF ABOUT 27-28N
SO WHILE AT LEAST A PORTION OF THE TROF SHOULD GET PICKED UP, BELIEVE
THAT SOME WEAKNESS WILL REMAIN WEST OF THE ISLANDS FOR THE NEXT FEW DAYS.
