A weak low pressure system is expected to track from west to east across the central and southern corn-growing region during the first part of the week. Rather weak southerly to southwesterly flow is likely immediately to its east given high pressure not that far away in the eastern corn-growing region. Given these factors and also potential prospects for rainfall causing some potential insect drop zones, Low migration risks are in the forecast for the next three nights to the east of the low pressure system and cold front. Low risks are predicted tonight into tomorrow morning mainly along and west of I-57 in eastern Illinois, including Kansas, Nebraska, southeast South Dakota, southern Minnesota, Iowa, Missouri, Illinois, and Wisconsin. The Low risk area shifts east tomorrow night into Wednesday morning, and includes eastern Missouri, Illinois, southern Wisconsin, Indiana, western Ohio, and southern lower Michigan. Low risks are then focused east of I-57 Wednesday night into Thursday as the system moves east, and include far eastern Illinois, Indiana, Ohio, southern lower Michigan, and extreme southern Ontario, Canada. Growers with crops at susceptible stages to corn earworm damage should be monitoring traps and scouting fields regularly as some moth flights were documented in the last week or so especially across the northern corn-growing region along with the possibility of additional isolated flights this week.
