It could be a white day after Christmas on Big Island summits and a wet and windy weekend for the rest of the state.

The National Weather Service says there’s a chance of snow late tonight and Saturday on Mauna Kea and Mauna Loa as temperatures drop below freezing at night, tradewinds pick up and unstable weather moves over the state.

Webcamera images this morning show clear skies and small patches of snow remaining on the ground on Mauna Kea.

The forecast for Christmas for lower elevations calls for partly sunny skies and breezy tradewinds of 15 t o 25 mph with highs between 78 and 83 degrees.

But showers are likely Christmas night into the weekend and tradewinds will pick up to 15 to 30 mph.

Forecasters said the strong winds will bring rain clouds over the islands and unstable atmospheric conditions will contribute to a wet weekend.

“Most of the low clouds and showers are affecting windward and mauka areas. But some showers are reaching leeward sections,” forecasters said in an advisory this morning. “The blustery, wet tradewind weather pattern will remain in place through Sunday.”
