Surface high pressure north of Hawaii will promote breezy 
easterly trades that should continue through the weekend and into 
early next week. Periods of transient above normal moisture levels
will keep this a showery pattern especially Friday-Saturday, with
the showers favoring windward and mauka areas.

High pressure is forecast to weaken and pull away Tuesday and 
beyond, while a trough aloft approaches. The trades are likely to 
at least weaken somewhat, but with uncertainty in how much the 
winds could veer and weaken in response to a cold front northwest 
of Hawaii. This front may draw moisture northward and increase 
shower coverage by late next week, especially over the 
northwestern islands, but will continue to monitor as this 
forecast remains uncertain.
