LIGHT SOUTHEASTERLY WINDS WILL SWITCH TO NORTHEASTERLIES SATURDAY AS THIS TROUGH PASSES ACROSS THE ISLANDS. EAST TO NORTHEAST WINDS WILL THEN PERSIST THROUGH THE REST OF THE FORECAST PERIOD. AN UPPER RIDGE NOSING IN FROM THE WEST WILL WORK TO STABILIZE OUR AIRMASS BY SATURDAY...REDUCING RAINFALL AMOUNTS. && .DISCUSSION... A SURFACE TROUGH PERSISTS JUST WEST OF THE MAIN HAWAIIAN ISLANDS...INDUCING CONTINUED SOUTHEAST LOW LEVEL FLOW ACROSS LOCAL WATERS. HOWEVER...THE PRESSURE GRADIENT IS RATHER SLACK AND WINDS ARE LIGHT. SHOWERS INCREASED DRAMATICALLY JUST AFTER MIDNIGHT NEAR NIIHAU AND HAVE SINCE FILLED IN SOUTH THROUGH WEST AND NORTHWEST OF KAUAI.

A SHIFT TO NORTHEAST WINDS TONIGHT AND SATURDAY WILL OCCUR AS HIGH PRESSURE BUILDS TO THE NORTH AND NORTHWEST OF THE STATE.
