Alert Details

As a cold front continues to push east through the corn-growing region, any corn earworm migration risks will also be shunted off to the east as well. A Low migration risk is predicted tonight into Thursday morning mainly across the southern Great Lakes region and eastern Midwest as southwest winds are expected to continue to the east of the cold front in this area. Otherwise, no corn earworm migration risk is predicted in the next five days as northwest to southeast flow is expected to become dominant and high pressure building into the Plains keeps any southerly winds in source regions further to the south.
