A FAVORED COMPOSITE OF WELL CLUSTERED MODEL GUIDANCE HAS BROAD
ENSEMBLE SUPPORT OVERALL IN A PATTERN WITH AVERAGE TO ABOVE
AVERAGE PREDICTABILITY. SLOW PASSAGE OF AN AMPLIFIED MID-LATITUDE
SYSTEM TO THE NORTH OF THE STATE IS DISRUPTING ISLAND TRADES AND
WORKING A TRAILING FRONT ALONG WITH INCREASING CHANCES FOR
ENHANCED RAINS OVER THE ISLANDS. THE WEAKENING AND STALLING
BOUNDARY AND LAND/SEA BOUNDARIES SHOULD ACT TO POOL DEEPER
MOISTURE TO FUEL SOME DAILY LOCAL DOWNPOURS THIS WEEK. THIS
PATTERN SHOULD SLOWLY LOSE INFLUENCE OVER THE WEEKEND AND USHER IN
A RETURN PERIOD OF MODERATE TRADES AS HIGH PRESSURE BRIDGES TO THE
NORTH OF THE STATE. THERE IS A GROWING GUIDANCE SIGNAL THAT
SUBSEQUENT SOUTHEASTWARD DIGGING OF UPPER TROUGH ENERGY FROM THE
WEST-CENTRAL PACIFIC MID-LATITUDES EARLY NEXT WEEK MAY AGAIN
DISRUPT ISLAND TRADES AS AN ASSOCIATED AND SHOWER/THUNDERSTORM
FOCUSING FRONT SLOWLY NEARS THE STATE.
