Alert Details

A rather quick-moving, yet potent low pressure system and attendant cold front are expected to sweep from west to east across the corn-growing region over the next few days. A period of gusty south to southwest winds is likely in advance of the frontal passage, and despite the rather late time of the growing season for black cutworm migration, especially in a typical year, a Low migration risk is in the forecast especially across northeast Nebraska, South Dakota, southeast North Dakota, Minnesota, Iowa, and far western Wisconsin tonight into tomorrow. Late planting and slow crop growth may lead to some black cutworm issues later this month. Low risks continue in the forecast tomorrow night into Saturday morning mainly east of I-35 as the system moves east. Growers all across the corn-growing region are encouraged to continue scouting newly-emerged corn fields for signs of black cutworms given the numerous flights that have occurred this spring.
