Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 729 AM EST Thu Feb 09 2017 Valid 00Z Fri Feb 10 2017 - 00Z Fri Feb 17 2017 Models show excellent agreement that a well-defined cold front will move across the Hawaiian Islands Friday night into the weekend. The associated shortwave energy emphasizes the best potential for heavy showers to move through the western part of the island chain on Saturday before the main energy lifts out to the northeast on Sunday. Behind the front, slight ridging is indicated before a broad and less-defined front approaches on Tuesday. This front is forecast to slow down and become nearly stationary across the southern part of the island chain by the middle of next week. Kong
