Alert Details

With northwest flow being the dominant central United States weather driver for much of this week, little to no black cutworm migration risk is in the forecast until we get into next weekend. By that time, low pressure is expected to develop across the Plains with the overall flow shifting more out of the southwest. The result will be an increase in southerly winds especially to the east of a cold front that should trail from low pressure in Nebraska/South Dakota south into west Texas. Low migration risks are in the forecast for Friday night into Saturday mainly west of I-57 in Illinois and as far north as central Minnesota and Wisconsin. If the current forecast holds, we will likely be upgrading portions of the Low risk into the Moderate category later this week given the possibility for stronger southerly winds and also precipitation. Stay tuned to forecasts this week for the latest information!
