Alert Details

Southerly winds are expected to be quite prevalent across at least a portion of the corn-growing region through the next week and likely beyond, and these winds may lead to some isolated corn earworm moth flights. Lingering corn earworm concerns are with fresh market and processing crops at this point in the growing season, so these growers should continue monitoring traps and scouting fields, as needed, until harvest. Low risks are in the forecast mainly west of I-35 tonight into tomorrow, with the risk spreading east to Lake Michigan and the I-55 corridor in Illinois and eastern Missouri tomorrow night into Wednesday. Later in the week and next weekend, a complicated forecast is expected with a potential tropical storm moving into the southern United States and its likely remnants moving into at least a portion of the corn-growing region by late week. Meanwhile, low pressure lingers over southern Canada, keeping southerly winds going in the Plains and western corn-growing region. Broad-brushed Low risks are predicted across a large portion of the corn-growing region to account for both of these systems later in the week, but future forecast refinements are likely once confidence in placement increases mid-late week.
