Alert Details

A slow-moving cold front currently across the eastern Plains and into portions of the western corn-growing region is the dividing line between south to southwest winds to its east and west to northwest winds behind it. This front is expected to only move east and southeast to near the I-35 corridor over the next day, so Low migration risks will remain in the forecast mainly along/east of I-35 but west of Lake Michigan and the I-55 corridor in Illinois tonight into tomorrow. The risk area only shifts east to far eastern Illinois tomorrow night into Saturday, with Low migration risks finally expanding into the southern Great Lakes area and eastern corn-growing region by Saturday night into Sunday and continuing in the forecast through next Monday into Tuesday as the front finally makes more of a move to the southeast by that point. The primary threat at this early stage in the growing season is mainly to fresh market/processing/garden growers with vegetables at critical growth stages where corn earworm damage could occur.
