Today, Sunday November 23, 2014

Today windward and mauka areas can expect partly sunny skies with isolated showers. Meanwhile, the leeward side and coastline can expect a mostly clear morning before clouds begin to build in the afternoon as the sea breeze develops due to daytime heating. Isolated showers are possible in the afternoon and evening as well. High temperatures should fall in the range of 81° to 86° and around 71° at 5000 feet. Winds are expected to be variable from 5 to 15 mph.

Looking Ahead

Winds ahead of an approaching front will become light and variable and a diurnal land / sea breeze weather pattern will set up.. Moderate rainfall and stiff north winds are expected as the front pushes down the island chain. The front is now expected to move quicker, therefore arrival time for the Big Island has been moved up to Monday night. By the time the front reaches Hawaii County it will likely be disorganized and mainly composed of frontal remnants. Best chances for rainfall will be along windward and mauka areas on Monday. Behind the front, cooler temperatures and dry conditions are forecasted. By Wednesday we expect a return to more typical trade wind weather.
