A rather quick-moving low pressure system is expected to move from west to east along the United States/Canada border from late tomorrow into the weekend. Southerly winds are expected to develop later today in the Plains states and then shift east ahead of a trailing cold front south of the low pressure system. Low black cutworm migration risks are predicted overnight tonight into tomorrow morning mainly west of I-35, or across much of Kansas, far northwest Missouri, Nebraska, western Iowa, western Minnesota, and South Dakota. The Low risk shifts east with the front to between I-35 and I-69 tomorrow night into Saturday, or from Missouri, Iowa, and southeast Minnesota as far east as lower Michigan and Indiana. With northwest flow expected to remain dominant early next week, little to no additional migration risks are in the forecast at this time.
