Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 716 AM EST Fri Jan 27 2017 Valid 00Z Sat Jan 28 2017 - 00Z Sat Feb 04 2017 The headline of the upcoming week is the cold frontal passage Saturday, with current guidance in strong agreement on its occurrence and timing. In general, the guidance shows excellent agreement in the pattern expected not just near Hawai'i, but through a majority of the northern Pacific. The main impact of the approach and passage of the cold front will be to sweep a potential low in the tropics northward to the east of the 50th state and decrease trades through Saturday, followed by a strong increase in post-frontal northeast trades for Sunday through Tuesday after the cold front passes. Winds should decrease once more as a cold front moves through the Papahanaumokuakea National Marine Monument mid to late next week. Roth
