The ensembles indicate surface high pressure to move eastward along 30N Sat-Wed and strengthen with time. Good agreement exists on the high pressure near 35N/150W next Wednesday. 00Z GEFS and ECENS mean correlate well with each other. Trades will be on the increase next Sun-Wed as the gradient increases due to the strong high pressure. Fracasso
