Alert Details

An active weather pattern is expected late this week and into the weekend as a low pressure system develops in the Plains and moves east along with a trailing cold front to its south. With the overall weather pattern still in a dominant northwest flow, however, any migration risks should be more isolated in nature as periods of south to southwest winds are not expected to be overly strong. Nonetheless, Low migration risks are predicted tomorrow night into Friday mainly along/east of the I-35 corridor from eastern Kansas northeast into southeast Minnesota and as far east as the I-75 corridor in southeast Michigan and western Ohio. Low risks then continue mainly east of a line from near Springfield, Missouri to Chicago, Illinois both Friday night into Saturday and again Saturday night into Sunday as the front is expected to slow down a little bit as it moves east this weekend. Growers are encouraged to continue their trapping efforts but also with a higher percentage of corn now emerging, calculate degree days from documented flights in April or even very early in May as some new larvae may be emerging.
