The latest guidance over Hawaii continues to show a persistent
trade pattern with moderate to brisk winds and primarily windward
focused showers through the next week. Trades may strengthen some
this weekend as areas of surface high pressure merge north of the
state with any rainfall on the lighter side due to upper ridging
over the state and lower than average moisture. A pocket of
greater moisture (originally from what was Hurricane Adrian)
passes near/just north of Hawaii along with a broad upper weakness
from East to West around the early to middle of next week. This
may briefly increase rainfall across most likely northern islands.
Models seem to have a good handle on the overall pattern, but
continue to offer some differences in the smaller scale details,
especially mid to later next week as the upper weakness travels
through the region.
