Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 303 AM EDT Thu Apr 30 2020 Valid 00Z Fri May 01 2020 - 00Z Fri May 08 2020 Moderate to breezy mean trades will prevail over the islands into early next week as surface high pressure cells bridge to the north of the state. Limited rainfall will focus over favored windward terrain under ridging aloft, but some tropical moisture may work into the southern islands early next week. Rainfall may increase through next midweek as trades ease and heights fall aloft in response to digging upper trough energy and frontal approach downstream of a building dateline upper ridge. The 00 UTC GFS/UKMET offer a bit more trough amplitude than the 00 UTC ECMWF/Canadian and that may be more reasonable considering the growing amplitude of the upstream ridge common to most guidance. This would favor a more organized frontal approach toward the islands. Schichtel
