Forecast Discussion

High pressure is building to the north, increasing tradewind flow and stabilizing the atmosphere.  Fair weather is expected through the weekend with possiblity of showers imbedded within the trades.  Showers will be mostly restricted to the windward/mauka areas, however with the increased wind flow, few showers will be pushed to the leeward side.
