Black Cutworm
The active weather pattern is likely to continue across much of the corn-growing region for at least the next week or two, with weather systems moving through at least a portion, if not all, of the area every 2-3 days. The end result will be continued fairly regular chances for black cutworm migration, as well, with greater risks focused on systems that allow a little more time for southerly winds to stay established in one area for more than a day or so, as well as a more direct connection to active source regions especially in Texas. Low risks focus tonight into tomorrow mainly west of Lake Michigan, with some risk spreading as far north as South Dakota, Minnesota, and Wisconsin. As a cold front begins to move east, the primary risk spreads east into the southern Great Lakes and portions of the eastern corn-growing region. Later in the week and next weekend, some subtle risk remains along/south of a frontal boundary, mainly along/south of I-80, but better and more widespread risks re-emerge west of Lake Michigan in response to the next potentially stronger system expected to move through early next week. We anticipate that Moderate risks will become needed across a portion of the corn-growing region for this system later this week.
