700 FXHW01 KWNH 060657 PMDHI Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 257 AM EDT Sun Apr 6 2025 Valid 00Z Mon 07 Apr 2025 - 00Z Mon 14 Apr 2025 Surface high pressure rebuilds northwest of the state near 30-35 degrees north through early in the week, with mainly ENE trade wind flow expected, and then the high becomes centered north of the state by Thursday into Friday, with good overall model agreement across the Hawaii domain. In terms of rainfall prospects, mainly trade wind induced showers can be expected most days across the windward terrain. The ensemble means suggest an upper trough could develop near 150 degrees west by midweek, and this may result in a slightly greater coverage of showers during this time, but nothing major expected.
