A coastal nor’easter tracked slowly northward along the U.S. East Coast on September 26, 2026, delivering the primary rainfall to the Northeast. National Weather Service observations recorded 1.55 inches at JFK Airport in New York and over 1 inch across parts of southern New England and the mid-Atlantic, with localized totals exceeding 2 inches on northeast-facing slopes of the Catskills and Berkshires. Official reports from stations in California, Texas, and the Ohio Valley showed zero measurable precipitation that day. Steering patterns associated with the slow-moving low and its associated moisture plume concentrated measurable rain within a relatively narrow corridor from the Delmarva through coastal New England, consistent with typical nor’easter climatology for late September.
