Hawaii's weather looks to remain relatively dry and quiet through
this week into early next week, as an upper trough near the
western islands gives way to an upper high currently centered east
of the state that will gradually drift westward atop the state
this week. At the surface, a ridge of high pressure near the state
is causing weakened trade winds and allowing for a nighttime land
breeze/afternoon sea breeze pattern to set up. Isolated showers
are possible over interior and leeward areas in this pattern, but
should be few and far between given normal to below normal
moisture levels. While the surface high pressure ridge drifts
north over the next few days and causes moderate trades to
redevelop, moisture should remain below normal with the ridging
aloft. Thus windward and mountain showers from the trades should
stay modest. By next weekend, some older model guidance was
showing potential for increased moisture, but more recent runs
have kept this moisture axis north of Hawaii for a continued dry
pattern over the state. Trades may weaken somewhat by next weekend.
