Alert Details

Another strong weather system is predicted to pass through the corn-growing region early-mid week. This low pressure system may bring fairly widespread rain chances, including the potential for heavy rain and severe weather, but also strong gusty southerly winds which may lead to another black cutworm migration event. Low risks are in place ahead of the developing low pressure in the Plains and western/central corn-growing region mainly west of the Mississippi River tonight into tomorrow, and as far north as into South Dakota and Minnesota. By tomorrow, the system really ramps up in strength and southerly winds east of a trailing cold front are subsequently much stronger. As a result, a fairly broad area of Moderate migration risk exists from Missouri, central/eastern Iowa, and southeast Minnesota as far east as southern lower Michigan, Indiana, and Kentucky. Low risks extend from just west of the Moderate risk into southern Ontario, Canada, Ohio, and eastern Kentucky. Little to no risk is predicted late week and into next weekend as northwest flow returns following this system.
