Hawaii Extended Forecast Discussion

The guidance agrees that a warm core high strengthens to the north
and shifts northeast of Hawaii into next weekend should keep a
locally breezy trade wind pattern in place. Trades should weekend
late week into the weekend as an upper low moves nearby, the warm
core ridge to the northeast weakens, and a front slowly moves
through the Papahanaumokuakea Marine National Monument. 
Post-Tropical Depression 14-E is expected to pass far enough south
of the archipelago to preempt any major heavy rainfall threat,
though a modest uptick in shower activity cannot be ruled out. 
Showers through the next week will tend to focus over the
favorable windward/mountain areas but would become more feisty
late this week into the weekend.
