Alert Details

Moderate corn earworm migration risks are in place tonight into Wednesday morning across portions of Kansas, southeast Nebraska, western Iowa, and western Missouri as southerly winds and precipitation coincide in advance of a cold front. Scattered moth flights may continue in these areas as trap counts have increased over the weekend across portions of the Plains states. Lower risks are predicted further north into the upper Midwest and central/eastern corn-growing regions of the southern Great Lakes and eastern Midwest. Low risks are predicted from Wednesday night into Thursday morning across mainly the eastern corn-growing region from Missouri and eastern Iowa and points east as a cold front continues pushing southeast. Southwest winds are not expected to be as strong, however, so the risk level is not as high. Looking ahead to next weekend, Low risks are maintained mainly across the Plains Friday night and into the central corn-growing region along I-80 and west of the Mississippi River for Saturday night as the next cold front pushes through. Once again, weaker expected wind speeds keep the risk limited during this time.
