Looking Ahead
Trade winds will increase to locally breezy levels by Wednesday, then ease toward the weekend as high pressure first strengthens to our north then weakens as it gets edged out by a front approaching from the west. Trade winds will push clouds and showers across the islands, focusing rainfall mainly across windward and mauka areas, with only light amounts expected. Showers will increase late in the work week and over the weekend as a weak surface low forms along a trough across the islands, with locally heavy rainfall possible.
