A stalled frontal boundary combined with upper level troughing
will continue to bring showers and a few thunderstorms to Hawaii
during the first half of this week. Locally moderate to heavy
showers are possible as deeper moisture gets pulled over the
islands ahead of another front passing to the north Tuesday and
Wednesday. From Thursday through at least the weekend, models
agree that the forecast should dry out as the upper level system
pulls away and ridging builds back east across the state. As the
resulting surface high pressure builds to the north, this should
allow for resumption of more typical light to moderate trade
winds. By early next week, another cold front may begin to
approach the islands, which should shift the low level winds to a
more south/southeasterly direction ahead of the front.
