Trade winds should relax this week, ushering in a drier and more
stable pattern over Hawaii. Any showers are likely to stay
confined to windward facing terrain areas as high pressure builds
north of the islands. The guidance continues to show that upstream
upper ridge amplification over the west-central Pacific should
allow rounding shortwaves to dig southeastward towards Hawaii the
latter half of the next week, which could bring brief disruptions
and shift towards more northerly trades later this week. 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.
