Trade winds should remain weak through this week and into this
week allowing for a drier and more stable pattern over Hawaii. Any
showers are likely to stay confined to windward facing terrain
areas. The guidance continues to show 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 later
this week and next 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.
