Looking Ahead 

High pressure is expected to weaken over the next couple of days. Showers will mainly favor windward and mauka areas with some passing leeward from time to time on our breezy winds. An increase in high clouds is expected starting the middle of this week particularly for leeward areas. Rainfall could also increase for the second half of the work week, will keep an eye on it.
