    Looking Ahead

    A high pressure ridge far to the north of the Hawaiian Islands will continue to maintain moderate trade winds through next week Friday. Enhanced showers mainly over windward and mountain slopes will continue in an unstable environment through Sunday. Some showers will drift over leeward areas at times, especially in the overnight periods. Drier and more stable weather returns to the island chain on Monday and Tuesday. A more active shower pattern may develop on Wednesday and Thursday as a disturbance in the deep tropics passes south of the Big Island.
