The weather pattern is largely dominated by a northwest to southeast flow especially across the northern half of the country. As a result, the primary storm track is focused further to the south across the southern and mid-south regions of the United States. Corn earworm migrations, therefore, are expected to be non-existent or more limited into the corn-growing region until potentially next weekend. An upper level low pressure system should continue moving east through the mid-south today into tomorrow. Southerly winds to the east of this feature are pretty limited and are stronger further to the south across active source regions so no migration risk is predicted into tomorrow morning. A Low migration risk is predicted across the eastern Midwest on Wednesday morning, however, as enough southerly winds may result in isolated moth flights into this region. Low risks are also in place across the western Plains by Saturday morning as another area of low pressure develops east of the Rocky Mountains and high pressure moves east from the central United States. Enough southerly winds may be present by that time to result in isolated moth flights to western portions of the corn-growing region.
