Alert Details

Low pressure is likely to organize in the High Plains by this weekend before tracking to the northeast into Canada. A trailing cold front to the south of the low pressure center will divide south to southwest winds to the east from west to northwest winds to the west. With high pressure moving into the eastern Great Lakes region, a potential black cutworm migration event may be possible especially in more isolated and late-planted fields across the western and northern corn-growing region this weekend into early next week. Low risks mainly focus in the Plains states Friday night into Saturday morning and Saturday night into Sunday morning, but do expand east to Lake Michigan and central Illinois by Sunday night into Monday morning. Growers especially west of the Great Lakes should monitor for new black cutworm moths especially as we move into next week and if fields have just recently been planted. Emerged corn will likely not be affected by this potential flight as it should outgrow any new cutworm flights and subsequent hatch risks.
