The closed upper low that has developed near 175W, along with its
associated inverted surface trough, is forecast to slowly drift
westward and away from Hawaii over the next few days.  The col in
the upper ridge is expected to fill in as the ridge axis expands
and the surface high to the north of the state builds.  There may
be a weak upper trough that tracks just south of the Islands by
the end of the week and into the weekend, and perhaps another
break in the ridge by the end of the forecast period.

In terms of sensible weather, the building high north of the state
will tend to increase the Trades with windy conditions at times
for the beginning to middle of the week, with a slight backing of
the winds from ESE to ENE expected.  Mainly terrain induced
showers can be expected for much of the forecast period, with a
better chance for more enhanced rainfall by the weekend owing to
the upper trough approaching.  It appears that the heaviest
rainfall should remain south of the Big Island based on the latest
model projections.
