Trade winds should remain weak through the next seven days
allowing for a drier and more stable pattern over Hawaii. Any
showers are likely to stay confined to windward facing terrain
areas. The guidance shows good agreement that upstream upper ridge
amplification over the west-central Pacific should allow rounding
shortwaves to dig southeastward towards Hawaii, which could bring
brief disruptions and shifts towards more northerly trades into
this weekend. The latest models suggest the associated cold fronts
with these systems should weaken and die out north of the islands
though, so limited to no moisture/QPF impacts are expected.
