A low pressure system and attendant cold front in the eastern Plains/western corn-growing region is expected to merge with remnants of Tropical Storm Cristobal which is expected to move up the Mississippi River valley and into the northern Great Lakes today into tomorrow. Southerly winds to the east of both of these features may lead to isolated corn earworm moth flights mainly east of a line from Springfield, Missouri to Wausau, Wisconsin. Any flights are expected to be isolated in nature and with crops and other plants in mid-south source regions still attractive hosts for corn earworm and lack of widespread suitable hosts further north, this supports additional confidence of just Low migration risks despite a favorable weather pattern. Fresh market and garden growers should scout any vegetables that may be at susceptible stages to damage as some recent or anticipated isolated flights may have or could occur. Little to no additional risks are predicted for the rest of the week once this system departs tomorrow.
