Cool and breezy trade wind weather will continue through Saturday with trade winds gradually diminishing Sunday into Monday. The trades will bring periods of clouds and a few showers to windward areas. Increased moisture approaching the islands from the southeast could fuel additional windward showers on the Big Island and Maui this weekend. Trade winds will slow down to moderate speeds on Sunday and become light and variable Monday night into Tuesday. A cold front is expected to move down the island chain on Tuesday, bringing a brief period of showers, followed by another round of cool and breezy weather.
