Alert Details

The weather pattern is expected to now shift away from a dominant northwest flow that we have seen for the majority of the month of May to one that is likely to allow warmer temperatures as well as an increase in southerly winds. These southerly winds may lead to isolated black cutworm moth flights over the next several days. Low risks are predicted tonight into tomorrow mainly east of I-35 from eastern Kansas, Missouri, Iowa, and southeast Minnesota as far east as western Indiana as a corridor of southerly winds sets up ahead of a weak frontal boundary. Low risks then continue over the weekend across the Plains and then further east into Illinois, Indiana, southern Michigan, and western Ohio as this same front meanders in the Missouri/Illinois and southern Great Lakes vicinity. Low risks encompass much of the corn-growing region south of I-90 early-mid next week. Growers should continue scouting efforts especially with emerging and early vegetative growth corn now present in many areas as moth flights that occurred in the past several weeks to month may now be producing larvae from new generations.
