LOCATION...HAWAII...

ATTN RFCS...AKRFC...
.
EVENT...UPPER LEVEL TROUGH MOVING THRU CENTRAL ISLANDS...RELIEF FOR
KAUAI AND OAHU...STILL LOCALLY HVY RAINS ISLAND EAST OF OAHU...
.
SATELLITE ANALYSIS AND TRENDS...HOW DO YOU SAY RELIEF...NORTH TO NWLY
FLOW...NOW HAS MOVED AS FAR EAST AS OAHU.  0145Z SATELLITE WINDS ON
CURRENT WATER VAPOR LOOP/IR LOOP SHOWING WIND VECTORS FROM A NORTHERLY
DIRECTION OAHU AND WESTWARD AND THIS SUPPRESSING THE BIG SHOWERS WE HAVE
SEEN ON OAHU AND KAUAI THE PAST WEEK OR SO.   STILL MAY BE OROGRAPHIC
SHOWERS BUT DON'T THINK THEY ARE ORGANIZED ENOUGH TO CAUSE PROBLEMS.
AND PW LOOP SHOWING AREAL EXTENT OF DRIER AIR HAS BEEN EXPANDING AS
TROUGH HAS SLOWLY DRIFTING EAST PAST 24HRS.  BUT STILL LOWEST PW VALUES
NORTH AND JUST NW OF KAUAI AT JUST UNDER 1.0" AND KAUAI AND OAHU AT 1.1
TO 1.3" PW VALUES...SO STILL ENOUGH FOR SHOWERS WITH MOUNTAIN LIFT...BUT
DON'T THINK ENOUGH FOR ANY PROBLEMS.
IT IS ANOTHER STORY EAST OF THE CENTRAL ISLAND TROUGH AS BEST PW MOISTURE
ABOUT 100 MILES EAST OF THE BIG ISLAND AT 1.7" HAS BEEN FORCED WEST WITH
TROUGH MOVING EAST THRU CENTRAL ISLANDS AND THIS HAS BEEN KEEPING SHOWERS
ACTIVE OVER THE BIG ISLAND.  BUT IT APPEARS THAT WITH THE ELIMINATION
OF DAYTIME HEATING AND NO REAL GOOD SHORT WAVE TRIGGERS...THERE MAY BE
A LULL IN PRECIP FOR THE BIG ISLAND THIS EVENING.   BUT WILL KEEP AN
EYE AS MOISTURE NEARBY AND UPPER LEVEL TROUGH STILL TO THE WEST FROM
15N/161W TO 21N/157W.
WILL CONTINUE TO MONITOR...
