Low pressure is expected to develop across the High Plains east of the Rocky Mountains over the next few days. Southerly winds to its east will expand and increase as high pressure moves into the eastern United States. This is not expected to be an overly strong system, thus wind speeds are not likely to be very high but still could result in some isolated black cutworm moth flights mainly south of I-90 from southern South Dakota into southern Minnesota and west of the US51 corridor in Illinois and southern Wisconsin tomorrow night into Thursday. Low risks then expand eastward Thursday night into Friday as far east as lower Michigan, Indiana, Ohio, and Kentucky as the low pressure begins to make advances east. After Friday, however, the low begins to dissipate and southerly wind flow really drops off at insect flying level so no additional risks are in the forecast over the weekend.
