Alert Details

A weakening cold front is predicted to push slowly southeast especially across the upper Midwest into the Plains states over the next couple of days. This front divides warm and rather humid air to the east from cooler and drier air to the west, but more importantly south to southwest winds to its east from westerly to northwest winds to the west. The south to southwest winds may lead to some isolated corn earworm migration risks for the next couple nights especially from I-35 east into the southern Great Lakes and eastern corn-growing region. Growers should be advised that these early season flights are not necessarily a threat to crops at this time, but later generations that may cause damage later this summer could result from these flights at this time.
