Today, Friday November 21, 2014
Today windward and mauka areas can expect mostly cloudy skies with ares of scattered 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. The UHSOEST vog model is predicting voggy conditions for the south and west ares of the Big Island (see forecast image above). High temperatures should fall in the range of 81° to 86° and around 71° at 5000 feet. Winds are expected to drop slight with east winds from 10 to 20 mph expected.

Looking Ahead
Trade winds are expected to remain breezy through the week with lighter winds currently forecasted for the weekend. A gradual weakening trend is currently underway. A front is expected to reach the islands early next week, pushing down the island chain to Hawaii County sometime late Monday, early Tuesday and bringing an increase in showers. Ahead of the front winds will weaken and a diurnal land / sea breeze weather pattern will set up. That in combination with unstable conditions could spawn heavy showers Sunday afternoon.
