Guidance overall agrees that a mean upper trough position blocked
just to the northwest of the islands by upper ridging is acting
to veer light to moderate island trades along with only a modest
increase in moisture and showers as deep moisture holds offshore.
Trades may become moderate to locally breezy mid-late week and
continue to slowly strengthen into the weekend as high pressure
bridges to the north of the state, but moisture remains limited.
