EVENT...MAIN TROUGH OVER THE EASTERN ISLANDS...WEAKER SECONDARY TROUGH
OVER THE WESTERN ISLANDS...
.
SATELLITE ANALYSIS AND TRENDS...INSTABILITY HAS BEEN THE DOMINANT TRIGGER
FOR CONVECTION/HVY RAIN HAS PW MOISTURE HAS GENERALLY DECREASED SLIGHT AND
A LITTLE MORE DRIER AIR FROM THE WEST HAS DRIFTED EAST.  MAIN UPPER TROUGH
ON WATER VAPOR EASTERN ISLAND HELPING DECREASE STABILITY EASTERN ISLANDS
AND CLOSE PROXIMITY TO HIGHEST MOISTURE JUST OFF BIG ISLAND ALLOWING FOR
LOCAL HVY RAIN EAST COAST.  JET NEAR BY TOO AND WEAK SURFACE MOISTURE
CONVERGENCE COULD ALLOW LOCAL HVY RAIN TO CONTINUE A WHILE LONGER EAST
TIP OF THE BIG ISLAND.  IN THE WESTERN ISLANDS...WEAKER SECONDARY TROUGH
PROVIDING ENOUGH INSTABILITY FOR AFTERNOON CONVECTION MOSTLY OVER THE
MOUNTAINS...BUT LOSS OF DAYTIME HEATING AND LOWER PW MOISTURE HERE ALREADY
HAVING THE EFFECT OF WEAKENING CONECTION AND LOWERING RAINFALL RATES
ON OAHU.  ODD ISLAND OUT IS MOLOKAI WHERE RAPID COOLING OF OVERSHOOTING
TOP TO -44C (FROM -14C AN EARLIER BEFORE) PROBABLY RESULTED IN AT LEAST
1.0"+ OF RAIN BUT APPEARS TO BE SLIGHTLY WEAKENING ON RADAR.
WILL CONTINUE TO MONITOR...
