An increase of the Trades through the middle of the week will
generally favor a pattern with mainly terrain based showers,
especially as some enhanced moisture advects in from the
southeast.  Models and ensembles remain in very good agreement,
and signal the development of a rather anomalous closed
low/organized surface low to the northwest of the islands by the
end of the week.  A southward trailing cold front will be slow to
approach the western islands as upper ridging builds over the
state from the northeast.  Deepening lead moisture may feed into
the western islands to fuel showers/heavy downpours late this week
and into the weekend as the front stalls and southeast
veered/weakened trades develop over the islands.  The trades
should turn easterly and strengthen as the low lifts northward
away from the region as high pressure settles in to the northeast
of the state.
