Winds are forecast to veer toward the east Thursday as a weak
surface ridge sets up north of Hawaii. These light to moderate
easterly trades should continue through Friday and gradually
decrease in strength over the weekend, especially Sunday. Moisture
levels will be on the lower side for only some limited showers
favoring windward/mountain areas.

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 themselves. By midweek the western islands may have a
greater chance of seeing southerly/southwesterly winds as the
front gets closer, and models suggest the front may reach Kauai by
next Thursday. The southerly flow (at least aloft) may gradually
moisten the atmosphere, but with a mid-upper ridge overhead,
shower coverage does not look to expand much until along the
approaching front itself later next week.
