Alert Details

An active but progressive weather pattern is expected to persist for the next five days. The progressive nature of weather systems across the central United States will likely limit corn earworm migration since the window of opportunity for moths to move north will be limited. Low risks are in place tonight into Friday morning primarily across Kansas, Nebraska, and southern South Dakota as the next low pressure system moves into the Plains states. The risk area shifts east and expands to as far east as near Lake Michigan and into Illinois for Friday night into Saturday morning, and finally into Indiana by Saturday night into Sunday before southwest wind flow really weakens or turns to a non-favorable direction for migration. Growers should monitor for the possibility of a few new migrants in the next week especially on host plants.
