Expect a continuation of relatively dry conditions during the
period.  At times there will be some variability in winds and thus
focus for any light rainfall that does occur, as the islands will
be near the southern periphery of systems carried along by the
mid-latitude westerlies. 

Early in the period a front will progress southeastward into the
islands Sun night-Mon, gradually weakening as it approaches the
Big Island.  Into early Mon this front will be accompanied by a
narrow band of 1.25 inch or so precipitable water values which
will likely end up being the highest seen over the islands during
the full forecast period.  Still what rain occurs along the front
should be light.  Passage of the front will bring a brief period
of stronger winds from the north/northeast and then lighter winds
as a weak trailing high drifts over the region.

From late Tue into later in the week the pattern will stabilize
some as the combination of eastern Pacific high pressure and wavy
front approaching from the northwest support
easterly/southeasterly winds near the Big Island and southwesterly
winds to the northwest.  Small scale of frontal waves would
support lower than average predictability for position of the
front at any particular valid time, favoring an intermediate
solution for exact timing as it nears the northwestern islands. 
Expect this front to stall/weaken as another front approaches
during the weekend.
