Breezy trade winds this weekend should weaken early this week as
they veer southerly in advance of an approaching cold front. A
deep upper level low digging towards the region will drive this
front southward, possibly stalling over the northern/western
islands by midweek. Moisture should get pulled northward ahead of
the front resulting in increased rain chances across much of
Hawaii, with the best chance for any type of enhanced rainfall
near or along the front. Easterly and breezy trades should return
by next weekend as the front weakens and the upper system lifts to
the north and east. The guidance as a whole shows good agreement
on the overall setup for the next week, but continued spread on
the details, especially regarding moisture and rainfall amounts
for the midweek front. Therefore, the best approach would likely
be towards a consensus solution at this time.
