Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 816 AM EDT Fri Sep 27 2019 Valid 00Z Sat Sep 28 2019 - 00Z Sat Oct 05 2019 Upper ridge axis to the northeast of the region will translate through Hawai'i and then back to the west by Sunday. From next Tue-Fri the upper high will meander to the north and north-northwest of the area. Models and ensembles show good agreement on this overall pattern evolution which will bring in lower heights over the state next week to the south of the upper high. Trades will increase next week as the pressure gradient increases with typical windward/mauka showers through the period amid typical precipitable water values. Some locally-enhanced higher rainfall totals are possible per some model forecasts. Fracasso
