Looking Ahead

ARTICLE CONTINUES BELOW AD

The possibility of heavy rain and thunderstorms continues through Thursday. A strong disturbance is passing over the islands and creating unstable conditions. The band of moisture that brought us wet and stormy weather is forecast to move north Thursday which should shift the threat of heavy rain to Oahu and possibly Kauai. Gradually improving conditions are expected Friday, with a more settled weather pattern expected for the weekend, with light winds bringing humid conditions.

 

Today  

We have variable winds today around 5 to 15 mph. High temperatures are forecast from 76° to 81°. Partly to mostly cloudy today with scattered showers and a chance of thunderstorms and locally heavy rainfall as well. If thunderstorms do develop they can be accompanied by gusty winds.

UV index at 9 (“very high” exposure level)

 

Tonight 

Variable winds are forecast around 5 to 15 mph. Partly to mostly cloudy skies are expected for Hawaii County with scattered showers and a slight chance of thunderstorms and locally heavy rainfall. Low temperatures from 67° to 72°.
