A reasonably strong surface high will meander well north of Hawaii
around 40N latitude through the rest of the week into next week.
The influence of this high will lead to persistent generally
moderate to breezy easterly trades, with likely just minor
variations in speed from day to day. Thus clouds and showers that
may form should favor windward and mauka areas. But with ridging
aloft over the next several days, an inversion will keep any
showers shallow. Additionally, the period from Friday into Sunday
or Monday looks to have lower than normal moisture in place as
well, limiting shower activity further. The ridge pattern aloft is
likely to last into the middle of next week, with perhaps the
south end of an upper trough edging toward Hawaii after that. But
a drier trade wind pattern should last through late this week and
into much of next week.
