Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 753 AM EDT Sun Jun 19 2016 Valid 00Z Mon Jun 20 2016 - 00Z Mon Jun 27 2016 Upper high to the north of the state near 40N/160W will strengthen over the next few days and then weaken and shift westward later in the week into next weekend. This will allow increased troughing to slide into the region from the northeast. This should support periods of generally light rain this week with increased coverage and amounts by next weekend. Cluster of 06Z GFS and 00Z ECMWF/Canadian form a good consensus near the ensemble means. Fracasso
