After a weak front has passed through Hawaii, winds are forecast
to have a northerly component over the next couple of days, with
sheltered areas perhaps developing land/sea breezes. Relatively
dry conditions and cool mornings are likely. A weak surface ridge
setting up north of the state beyond midweek should cause winds to
gradually veer toward the east. Moisture should become even more
suppressed by Thursday-Friday as a mid-upper high comes overhead.
Light to moderate trades and mostly dry weather are likely to
continue into the weekend.

By early next week models show a general signal for a front north
of Hawaii but disagree on its position. The ECMWF takes this front
farther south--still north of the state, but close enough that
winds turn to southerly in response by Monday, whereas GFS runs
maintain easterly trades. Even into Tuesday when the frontal
position starts to align a bit better, models differ with its
influence on the winds. So this will continue to be monitored as
potentially impactful to the wind pattern over Hawaii.
