Looking Ahead

ARTICLE CONTINUES BELOW AD

As a frontal system sags toward the state, trade winds are forecast to slowly weaken with a land and sea breeze pattern taking over and becoming more prevalent. Light background easterly winds are expected to still bring clouds and showers for windward spots from time to time. Afternoon clouds and showers are expected over interior and leeward areas from Sunday through much of next week.

 

Today & Sunday 

ARTICLE CONTINUES BELOW AD

We expect east winds around 15 mph but becoming light and variable by Saturday night and through the rest of the weekend. High temperatures are forecast from 85° to 90° and feeling muggier on Sunday with the light wind conditions. Partly sunny skies with showers likely in windward spots. Sunshine for the Kona side in the morning with a chance of showers in the afternoon. Areas of haze are expected for the leeward side as well. On Sunday, showers will be mainly during the afternoon hours for leeward and interior areas.

UV index at 12 (“extreme” exposure level)

 

Tonight & Sunday Night

Light and variable winds with a land breeze developing at night. Clouds and showers in the evening are expected to clear as the night goes on. Low temperatures from 70° to 75°.
