High pressure will settle across the state resulting in modest
trade winds through the week. Some lingering moisture/showers
could be possible on Tuesday, particularly for the Big Island,
associated with a dying stationary front east of Hawai'i then
drying out on Wednesday. Models indicate an upper level trough
approaching the area by Thursday. This will bring the tail end of
a front north of the islands Friday morning, pushing southward
through the weekend. As a result, an increase in precipitation as
well as breezy winds could be possible. By the beginning of next
week, typical trade winds/windward favored showers will return as
high pressure builds back into the area. Overall, models and their
associated ensemble means are in good agreement for the overall
pattern so prefer a composite solution.
