A mid to upper trough aligned just west of 170w will gradually
approach the Hawaiian Islands through the weekend. This amplified
trough will begin to draw back or allow return flow to encompass
most of the state... as precipitable water values hover around 1
inch. This setup will increase the chances for showers and locally
heavy rain through the weekend. As the upper trough axis moves
past the islands early to mid next week... a frontal zone will
move through the western islands and the entire plume of moisture
subsides some. Overall the guidance shows this scenario which
overall remains unsettled through the upcoming weekend.
