The recent bout of heavy precipitation has eased over Hawaii with
mid-upper level trough consolidation to the west of the state and
a slow shift of the deepest moisture just to the west and south of
the islands. Models and ensembles reasonably agree that lingering
moisture will continue to fuel showers over the next few days as
trades decrease in response to the shifting of supporting high
pressure from the north of the state to the eastern Pacific.
Rainfall may be enhanced Thursday with return moisture flow ahead
of an approaching front from the northwest in disrupted trade
flow. The mid-upper level trough supporting the front should push
through the islands Friday. This will usher in drier post-frontal
weather this weekend and early next week in a period with
returning trades as high pressure rebuilds to the north of the
state.
