Windy trades are likely to persist over the next couple of days
with a strong surface high to the north, with channeling strong
winds in favored areas. Some moisture in place will produce
showers favoring windward and mauka areas, with some spilling into
leeward areas. By late week though, the surface high should
weaken and drift southeastward, allowing for winds to gradually
weaken to more moderate levels by Saturday. Winds may raise
somewhat to more breezy levels into next week. Meanwhile, an upper
trough axis is forecast to approach from the west with some
lowering heights over Hawaii. This plus a front stalling to the
west will draw higher moisture northward across the state as mean
flow turns southeasterly. Thus more shower coverage and higher
rain totals are possible over the weekend into early next week,
especially over the western islands.
