Upper level ridging will be in place over the Hawaii domain
through the end of the week and into Saturday, before a large
scale trough builds in north of the state for the beginning of
next week.  At the surface, the subtropical surface high will
remained anchored in place near 35 degrees north, and this will
break down as a col develops within the ridge across the western
Islands by Saturday, and a trailing cold front from the North
Pacific system will likely reach the central and northwestern
Islands by Monday based on the latest GEFS and ECENS means.

Steady easterly trades through Saturday will support enhanced
showers across the typically favored terrain, mainly across the
Big Island.  The winds veer to the southeast as the front
approaches Sunday and into Monday, and northeasterly flow behind
the boundary for early next week along with slightly cooler
temperatures.  Rain chances will also increase for the central and
western Islands ahead of the front, although nothing major is
currently expected.
