Looking Ahead

ARTICLE CONTINUES BELOW AD

A weak trough of low pressure west of the state this afternoon, will slowly push eastward across the island chain tonight through Saturday. An unstable airmass is expected to accompany the weather feature as it moves through, bringing unsettled weather along with the potential for heavy rainfall and thunderstorms. The trough will shift east of the state on Sunday with a drier airmass moving back over the islands. A cold front will then approach from the northwest on Monday and slowly push southeastward through the state Monday night through Tuesday night. High pressure will then build north of the state during the middle to latter part of next week, with light to moderate trades along with a cooler and drier airmass returning to the islands.
