A cooler and drier airmass will be in place across the state on
Friday behind a cold front, with northerly winds. Onshore flow to
the northeastern sides of the Big Island and Maui may produce some
ongoing showers through Friday and Friday night per the HREF, but
precipitation is not expected elsewhere. A surface high will track
eastward to the north of the state (centered around to just north
of 30N) through the weekend into early next week. This will help
cause winds to gradually veer to northeasterly this weekend and to
a more typical easterly direction early next week. Drier than
normal precipitable water values are likely to remain in place
through the first half of next week, but some showers may affect
windward and mountain areas. The atmosphere looks to gradually
moisten late next week while upper and surface lows develop well
west of the islands. This may lead to increasing showers but the
details are yet to be determined at this point.
