Guidance continues to agree that broad surface high pressure will
remain in place to the north of the state with persistent
moderate trade winds expected through the period. This will favor
Upslope/Mauka showers each day. A plume of higher moisture
associated with Douglas in the eastern Pacific may reach the
islands later next week bringing a brief increase in shower
chances/rainfall before drier conditions return into the weekend.
