A rather potent upper level low will be situated to the northwest
of Hawaii on Thursday with an accompanying surface low centered
near 30 degrees north.  This feature is progged to lift northward
and evolve into an open wave by early Saturday as a large upper
ridge builds in to the northeast of the state.  By early next
week, both the GEFS and EC means are in very good agreement on the
development of a second closed upper low around 175W, and track
generally westward as the upper ridge rebuilds north of the state.


In terms of sensible weather, light to moderate Trades for the end
of this week and into this weekend are expected to become stronger
as the surface high builds in to the north and tightens the
pressure gradient, with windy conditions at times.  The two low
pressure systems are expected to be far enough away to keep the
heaviest rainfall well offshore, with mainly terrain induced
showers for much of the forecast period, with no significant
incursions of deep tropical moisture expected.
