Alert Details

An active and warming weather pattern is expected across especially the western and portions of the central corn-growing region over the next week. The potential for very warm to hot conditions is possible especially across the Plains states and generally along/west of the I-35 corridor on increasing southerly winds this weekend and into next week. Before this occurs, a cold front will be dropping southeast over the next 24-48 hours, and Low corn earworm migration risks are predicted tonight into tomorrow mainly west of Lake Michigan with the risk shifting across the southern Great Lakes and eastern corn-growing region mainly east of the Mississippi River tomorrow night into Saturday as the cold front moves southeast before stalling out. The front is expected to return north as a warm front this weekend, and southerly winds and hot conditions are possible especially across the Plains. Low migration risks accompany the southerly flow mainly west of Lake Michigan during this time. Corn is entering into critical growth stages especially in earlier planted regions of Kansas, Missouri, and Kentucky, so growers in these areas should begin monitoring fields in addition to fresh market/garden/processing growers with vegetables at susceptible stages to damage.
