Typical “trade wind weather” is forecast to continue for the rest of the work week. From late tonight through Saturday, moisture associated with the remnants of Greg is expected to bring increased humidity. Showers are forecast to increase in mainly windward areas and some could get heavy Friday. The slopes on the Kona side of the Big Island could see some afternoon downpours. A drying trend is expected from Sunday into early next week.
