Easterly trade winds will be breezy on Monday under the influence
of a tight pressure gradient from a surface high centered 
northeast of Hawaii. This high will weaken gradually and winds 
should return to moderate to locally breezy levels by midweek and 
continue through late week and the weekend. Meanwhile aloft, a 
weak upper trough will retrograde across the state and may allow 
for a raised inversion while waves of higher moisture move 
through. This should lead to a comparatively wetter trade wind 
pattern through much of the week, especially for Kauai and 
vicinity where enhanced moisture lingers the longest. By the 
weekend a mid/upper high may sneak into at least the eastern 
islands and suppress some potential showers.
