Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 725 AM EST Sun Feb 15 2015 Valid 00Z Mon Feb 16 2015 - 00Z Mon Feb 23 2015 Heights are forecast to rise in the wake of the frontal passage with a gradual return to more typical trades by Tuesday. Another front will approach the NW islands late Thursday into Friday. Timing differences remain between the GFS/ECMWF and other models so a consensus appears appropriate since the clustering is fairly good. Guidance indicate that it may linger into Sunday before weakening near the Big Island. Fracasso
