Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 315 AM EDT Tue Sep 29 2020 Valid 00Z Wed Sep 30 2020 - 00Z Wed Oct 07 2020 A favored guidance composite shows weakening trades with amplified upper trough reinforcement to the north of the state and as an associated front settles to the northwest and north of the state. Expect transition from modest windward terrain showers to areas favored by land/sea breeze convergence. Tropical moisture and some heavier downpours may feed into the islands from the southeast late week through the weekend in response to a weakness aloft and as trades return a windward terrain focus.
