Models and ensembles show good agreement on an upper level low
lifting north of Hawaii while an associated frontal boundary
stalls over Kauai into Friday. This will bring increased rain
changes a possibly locally heavy rainfall to the westernmost
islands, though both the latest runs of the GFS and ECMWF agree
that the heaviest precipitation may remain just to the west. After
this, models agree that high pressure should build north of the
state, bringing a return to a more normal and breezy trade wind
pattern through the weekend and into early next week. Showers
across the remainder of the island chain should favor mainly
windward and mountain locations.
