Tropical Storm Cristobal remnants and its eventual track and phasing with a low pressure system and cold front in the Plains will be the main weather story over the next several days as the system takes a rare track north into the heart of the corn-growing region. Wind flow patterns east and northeast of Cristobal’s track through Arkansas, Missouri, and into Iowa and eventually the northern Great Lakes region and Canada are favorable for corn earworm migration, and what few similar tropical systems that have tracked through the corn-growing region earlier in the tropical storm season of late spring/early summer have historically resulted in at least isolated moth flights. If this system were another month later, we would be issuing elevated risks but given the time of year and crop stage, only Low risks are predicted from Missouri north into Iowa, Minnesota, and points east into the southern Great Lakes and eastern corn-growing region the next two nights. We encourage fresh market and garden/produce growers to scout fields as some crops may be near stages where damage from new corn earworm moth flights may eventually cause problems or where additional generations may result in damage over the next several weeks or month.
