A modest rebound in moisture,showers with light trades may last
into Monday as a slow moving upper trough/low spins to the
northeast of Hawaii as associated shortwave energy rotates down
over the islands. A favored composite of well clustered guidance
suggests that ample mid-latitude upper trough amplification to the
north of the state mid-late week will eject the upper trough/low
to yield a period of drier conditions for the islands. Moisture
and showers will increase late week as a front moves into the
state from the north. Post-frontal high pressure building into the
central Pacific may then support increasing trades and a returning
focus for lingering showers over windward/mountain areas.
