Alert Details

A slow-moving low pressure system is expected to track east from the Plains into Iowa today, with a trailing cold front to the south. East of the front, southerly winds will persist and may lead to scattered black cutworm moth flights especially across eastern Illinois, Indiana, Ohio, and southern lower Michigan where a Moderate migration risk is predicted. Low risks extend from further west in Illinois, eastern Missouri, and southeast Wisconsin as far east as southwest lower Ontario, Canada and central/eastern Ohio. Low risks continue in the forecast tomorrow night into Friday morning as the front continues east but with overall weaker southerly wind flow as the parent low pressure weakens. There is little to no migration risk for the weekend into early next week, but growers should monitor traps for potential flights as while there is no threat to crops at this time, documenting when flights happen now may pinpoint when new generation may emerge later this spring when newly planted crops emerge.
