Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 729 AM EST Wed Jan 14 2015 Valid 00Z Thu Jan 15 2015 - 00Z Thu Jan 22 2015 No significant changes and/or alterations needed. The 14/00Z forecast guidance continues with the theme of the local 7-day Hawai'i forecast. The 14/00Z GEFS/ECENS ensemble guidance seems to have made a slight correction across the mid-latitude Pacific---in response to the outcome of a cold pool aloft in the Bering Sea. This adjustment is to bring the long wave trough to a position near 170W longitude rather than settle along the Dateline. This does not make for change in the Subtropics through day 7---rather, it gives the GEFS/GFS equal 'footing' with the ECENS/ECMWF across the Pacific and downstream into the North American continent to day 7. A blend of the ECENS/GEFS should handle the flow and sensible weather features this 7-day period. Vojtesak
