An upper ridge over Hawaii should briefly retreat eastward as a 
deep upper low develops north of the state within an overall 
blocky pattern. The cold front for this system will approach and 
swing through the northern islands allowing for strengthening 
southerly winds and some increased precipitation chances. Guidance
shows the heaviest precipitation should remain west of the island
chain though. As the upper low lifts northward late this week, 
surface high pressure may again move in north of the state 
allowing for a more typical trade wind pattern.
