Showers are likely in windward and mauka areas tonight. Leeward spots are expected to have mostly cloudy skies and scattered showers in the evening, then clearing should take place. Trade winds are forecasted from 15 to 20 mph. Low temperatures from 67° to 72° are expected.

 

Looking Ahead 

Locally breezy trade winds are expected to continue through Tuesday. The trades should continue to transport clouds and showers mainly over windward and mauka sections of the island chain, with a few showers affecting some leeward areas at times. High clouds are forecasted to begin streaming over the state on Tuesday. A disturbance high in the atmosphere combined with enhanced moisture is forecast to produce unstable conditions with wet weather expected across most of the state starting Wednesday or Wednesday night. There is the potential for locally heavy rainfall to occur Wednesday night and Thursday.
