Little change to the previous forecast as a prevailing easterly 
trade wind pattern will persist across the islands through the
weekend into much of next week. Through Saturday, some moisture 
on the northern periphery of Tropical Storm Pena will continue to
enhance the cloud cover and shower activity across the eastern 
Islands, specifically across the windward areas of Hawaii and Maui
Counties. By Saturday night, much drier air following the 
moisture plume will move through the islands from the northeast, 
which will persist through the end of the period (next Saturday) 
with more seasonal variations in the shower/thunderstorm risk as 
PWATs drop back closer to normal according to climatological 
anomaly forecasts. Mauka and windward side showers will remain 
possible through this period, but they will be lighter and more 
isolated due to the prevalence of the dry air and 
lowering/strengthening inversions.
