VALID 00Z FRI JAN 05 2018 - 00Z FRI JAN 12 2018  
 
MODELS AND ENSEMBLES AGREE TO MAINTAIN A RELATIVELY QUITE HAWAIIAN  
WEATHER PATTERN INTO EARLY NEXT WEEK UNDER THE INFLUENCE OF DEEP  
LAYERED HIGH PRESSURE. MODERATE MEAN TRADE FLOW OFFERS BELOW  
NORMAL MOISTURE AND LIMITED WINDWARD RAINFALL POTENTIAL, WITH THE  
BEST CHANCE TO SQUEEZE OUT MOISTURE DEVELOPING THIS WEEKEND FOR  
THE SOUTHERN ISLANDS AS IMPULSE ENERGY DIGS ON THE EASTERN  
PERIPHERY OF THE MID-UPPER LEVEL RIDGE. THERE IS A DECENT SIGNAL  
FOR A PATTERN TRANSITION BY NEXT WEDNESDAY/THURSDAY TO INCLUDE A  
DISRUPTION OF TRADES AS A COLD FRONT WORKS INTO THE ISLANDS FROM  
THE NORTHWEST. THIS OCCURS AS A SUPPORTING MID-UPPER LEVEL TROUGH  
AMPLIFIES AND DESTABILIZING HEIGHT FALLS PASS TO THE NORTH AND  
OVER THE STATE.
