Guidance solutions continue to seem reasonably well clustered,
bolstering overall forecast confidence. Light trades may
significantly increase mid-later week into next weekend as high
pressure settles to the northeast and north of the state.
Meanwhile, an unsettling upper low/trough now digging south toward
the state early may linger in vicinity mid-late week before
shifting slowly westward. Pooling moisture and increasing lift
favor increased chances for some local downpours and a few
thunderstorms in a wet period to monitor, especially for the
western portion of the islands.
