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. The combination of upper ridging over the state and lower
than average precipitable water values should keep any rainfall
fairly light through the weekend. A pocket of greater moisture
(originally from what was Hurricane Adrian) passes through around
Monday-Tuesday along with a broad upper weakness from East to West
around the middle of next week. This could briefly increase
rainfall across portions of the state. 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.
