The pattern over Hawaii for the next week looks to hold 
stationary as an area of weakness/shortwave gets caught between 
strong high pressure to the east and west of Hawaii. This will 
help bring deeper ITCZ moisture northward with some heavy rainfall
potential for Hawaii this weekend and into next week. Moderate to
gusty easterly winds this weekend will weaken next week 
underneath this trough, with high pressure attempting to build 
back in over/north of the islands by later next week. The guidance
shows good agreement on this overall pattern, but still with some
uncertainty in the details which affect QPF distribution and 
amounts across the island chain.
