Latest guidance is agreeable and consistent in showing a typical
easterly trade pattern through the next week with periodic
fluctuations in wind speeds along with variations in moisture
(though with mostly near to somewhat below average precipitable
water values) that will have some influence on
windward/mountain-focused showers. Mid-latitude high pressure will
settle well to the northeast of the area supporting persistent and
breezy trades before beginning to weaken by midweek as the upper
ridge builds back in over Hawaii. By later this week and next
weekend, high pressure should then build well north of the state
with fairly weak trades.
