Alert Details

Corn earworm migration risks, including Moderate risks, are back in the forecast on a nightly basis through at least the middle of next week as the weather pattern is likely to be stalled across the central United States due to Tropical Storm Hermine moving north along the eastern United States coast. An area of low pressure will continue to develop across the High Plains and into southern Canada while high pressure tries to push east through the eastern Great Lakes and corn-growing region this weekend into early next week. In between the two pressure centers, south to southwest winds will be rather persistent with an eventual increase in precipitation chances especially near the front. Low risks are predicted tonight into tomorrow morning mainly along and west of I-35 from Iowa into Minnesota and points west. Moderate risks are then in the forecast tomorrow night into Sunday morning across northeast Nebraska, eastern South Dakota, Minnesota, far western Wisconsin, and into Iowa. Moderate risks continue in the forecast on a nightly basis right through the middle of next week and mainly for any fresh market and processing fields that are still at risk in Iowa, Minnesota, Wisconsin, and northern/central Illinois. Isolated migration risks remain in the forecast as far east as I-75 in Michigan and western Ohio from the early to middle portion of next week.
