DELMARVA — A dangerous heat dome is putting this year’s corn crop at serious risk as the region enters a critical growth window, according to market analyst Don Roose of U.S. Commodities.
Roose warns the crop is at a crossroads, with corn now entering its pollination stage — the worst possible time for extreme heat. Whether the heat dome shifts, expands, or breaks down in the coming days could determine final yields for the entire harvest. On Delmarva, that threat hits particularly close to home.
