Looking Ahead

Trade winds are back, and will be here for a few days. They will also turn a bit windy in some place by Tuesday. A band of clouds and showers has reached Oahu. It will continue to move south and east, getting to Maui by mid morning, then on to the Big Island early this evening. With trades, expect the showers to focus on the windward and mountain areas, especially the nights and mornings. Some of these showers will extend into the leeward areas of the smaller islands, but rainfall will be light. An eastward moving front will be in range by Thursday night to cause the trades to become lighter. Expect the front to move down the island chain over the upcoming weekend, accompany by some scattered showers.
