Trade winds should ease and stay light through much of this week
as weak troughing moves over the region and pushes high pressure
well to the northeast of Hawaii. Increasing mid-level moisture
(possible remnants of former tropical cyclone Jimena) is expected
to cross the region early this week but shouldn't bring more than
just generally light scattered showers for most and locally
enhanced activity across the typical windward and mauka areas. The
trough should drift north the state late week as high pressure
again tries to build over the islands bringing drier conditions
and a more typical trade wind pattern by next weekend. Models and
ensembles continue show fairly good agreement on the overall large
scale pattern with some uncertainties in the details.
