A relatively quiet weather pattern is expected across Hawaii over
the next week. Models/ensembles continue to show good consensus
that an upper-level high will build and persist across Hawaii
though late this week and into next week, with a strong surface
high becoming established well north/northeast of Hawaii. This
will support moderate trades along with a relatively dry air mass
through the period, with relatively sparse windward shower
activity. A tropical wave is shown in relatively well-clustered
model/ensemble guidance passing well south of Hawaii Sun-Mon. At
this time, it looks to remain far enough south that the primary
effects on Hawaii would be a tightening of the pressure gradient,
and a period of rather gusty trades. The Big Island may see the
northern edge of some deeper moisture associated with the wave,
and perhaps a brief increase in shower activity as the wave passes.
