A powerful early-season nor’easter is the dominant driver of wind gusts at Boston Logan Airport through September 28, 2026. National Weather Service forecasts from the Norton office project northeast winds with sustained speeds of 23–29 mph and gusts reaching 50–55 mph on Saturday, with similar peaks possible Friday night; gusts of 45–60 mph are warned for coastal Massachusetts. The storm’s long-duration onshore flow, combined with a tight pressure gradient against high pressure over Quebec, is producing these conditions, with the strongest impacts aligned along the coast. Official observations at Logan and NWS model updates through the weekend will determine the period maximum, as any westward track shift or intensification could push gusts higher while weakening would cap them below warning levels.
