Wet weather over the Big Island overnight reached the summit of Mauna Kea and left a dusting of snow this morning.

What the weather service calls “wet tradewind weather” is expected today over most of the state through Wednesday night.

Rain clouds are being blown over windward and mauka areas of most islands by the tradewinds. Some of the showers may move over leeward areas.

“Over the eastern and central parts of the state, we expect mostly moderate rains with a few locally heavier downpours at times. The highest rain chances will of course be over windward areas, but some leeward areas will see scattered showers as well,” forecasters said.

The snow on Mauna Kea melted by this afternoon. But the wet tradewind weather and cool temperatures in the upper atmosphere means there is a chance more snow may fall on Mauna Kea overnight.

Winds are likely to pick up Thursday and another band of moisture from a dissipating weather system could bring an increased chance of showers, mostly in windward and mauka areas, Friday or Saturday.
