Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 229 AM EST Fri Jan 01 2021 Valid 00Z Sat Jan 02 2021 - 00Z Sat Jan 09 2021 Upper ridging to the northwest of the region will shift over the island chain, promoting a rather quiet pattern through next week. Trades will decrease into the start of next week well ahead of a cold front north of the area. This front may dip toward the islands late Tue into Wed but likely wash out even as the upper high retreats back to the west. With precipitable water values only near one inch from time to time, light windward and mountain showers are forecast. A general model blend should suffice with good agreement overall. The 00Z GEFS mean was just a bit lower with heights by next Fri than the Canadian/ECMWF ensembles. Fracasso
