Winds are forecast to continue to have a northerly component
Wednesday in a post-frontal environment over Hawaii. These should
gradually veer toward the east as a weak surface ridge sets up
north of the state later this week. Moisture levels will remain
quite low as a mid-upper high comes overhead. Trades are forecast
to gradually decrease in strength over the weekend, especially
Sunday.

Into early next week, trades look to get disrupted as a cold front
approaches north of Hawaii and there is a general model signal for
winds to respond by turning more southerly, though perhaps weak
enough initially for land and sea breezes to dominate over the
islands. By midweek the western islands may have a greater chance
of seeing southerly/southwesterly winds as the front gets closer.
Despite the southerly flow (at least aloft), moisture levels do
not appear to increase significantly and the pattern may stay
relatively dry into much of next week.
