Alert Details

A complex and somewhat unique weather pattern for early June is expected early-mid next week as a low pressure system and cold front develop in the High Plains and interact with expected remnants of Tropical Storm Cristobal which is expected to make landfall near New Orleans, Louisiana late in the weekend and then move almost due north up the Mississippi River valley by next Tuesday/Wednesday. For corn earworm migration purposes, the Plains cold front should only bring a Low migration risk but with the risk extending from Kansas and Missouri all the way up into North Dakota and Minnesota given the favorable southerly wind flow. The source region, however, being in west Texas is not the most favorable area for widespread moth dispersal so only Low risks are predicted. Low risks extend further east into the Great Lakes and eastern corn-growing region by next week, however, as Cristobal may bring moths northward from both the southern states but there have also been some past research that has suggested such systems may also transport moths all the way from Mexico, also, especially given the track of the system. Low risks focus especially along/east of the Mississippi River by mid-week. This setup will be interesting to watch over the weekend, and we will have the latest information next Monday.
