Forecast: First Autumn days call for humid winds and pop up showers
Trades will make a return Sunday into Monday
HONOLULU (HawaiiNewsNow) - Happy First Day FULL DAY of Fall! And Aloha Friday! The weekend is finally here!!!!
Lots going on this weekend including the Aloha Festival! An area of low pressure far northwest of the Hawaiian Islands, will further weaken trade winds, allowing for land and sea breeze development across the islands into early next week. This pattern will maintain afternoon and early evening clouds and showers favoring mountain and island interiors, while land breeze development each night will limit clouds and showers through the early morning hours.
Current radar trends show scattered showers lingering offshore this afternoon, with the areal coverage of showers expanding rapidly across interior sections of the islands. Overall expect that showers will continue to expand across mountain and interior regions through early evening, as weak background trades maintain windward showers, and sea breeze circulations support leeward showers and clouds.
Low pressure well northwest of the islands will quickly drop southwest through the weekend. This system will eventually stall west of the state by Sunday, while a surface boundary drops in well north and northeast of the state. Additionally, a strong upper low (also well northwest of the islands) will follow a similar path of the southwest drifting surface low through the weekend, while model solutions continue to diverge by the beginning of next week. This pattern will weaken the pressure gradient north of the state and support weakly organized east to southeast trades through the weekend, which will reinforce the diurnally driven local sea and land breeze circulations.
A high surf advisory is no longer up but a new pulse will arrive for town and a country swell on top of that!
