The closed low that has been idling north of Hawaii this past
weekend is now lifting north and merging with a building trough to
its northwest.  This new trough is also expected to amplify in the
same general area through about Thursday before lifting out, and
this will bring a cold front potentially as far south as Maui and
Oahu on Friday.  Upper level ridging is expected to build back in
across the state by this weekend. 

In terms of trade winds, the general col in the surface high
through the end of the week and the proximity of the front will
tend to result in lighter and more variable winds with some sea
breeze showers at times south of the boundary.  With the front
reaching the central Islands late in the week, there will likely
be more of a northerly wind component that will eventually veer to
the northeast and then east by next Sunday.
