Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 153 AM EST Sat Nov 11 2023 Valid 00Z Sun Nov 12 2023 - 00Z Sun Nov 19 2023 Moderate to breezy trades are expected to support some mainly windward shower activity over the next couple of days. Meanwhile though, deep upper trough amplification over the eastern Pacific seems sufficient in most guidance to force a well defined cold front southward through the islands by Tuesday. A favored composite of model and ensemble guidance seems to offer a good forecast basis amid growing forecast spread over time for development of this feature. This front should focus moisture and an axis of precipitation with passage to again likely focus on windward areas. High pressure building into the north of the state in the wake of frontal passage should rejuvenate trades through next mid-late week before easing late week into next weekend, all in a pattern with decreasing moisture availability.
