Welcome to Adisseo's Weather and Mycotoxins Report
United States 30 Day Outlook
(August 2023)
Contributors: Thomas Novak (Novak Weather Consultants), Adisseo
The stubborn and fast moving west to northwest jet stream flow in our atmosphere will continue for much of August. In turn, the weather pattern that we experienced in July over the United States (U.S.) will likely continue through much of August.
Note: Drought conditions continue to persist over a large portion of southern Canadian prairies and the U.S. Midwest. Meanwhile, drought is now quickly becoming a concern over much of the southern Plains states.

***Disclaimer: Mycotoxin risk is highly dependent on cultivar, management conditions, and local conditions. Mycotoxin screening for multiple mycotoxins is always recommended to understand the mycotoxin contamination risk of grains and feedstuffs.

Choose your region:
General Mycotoxin Risk: Most of the nation’s corn is planted across the Midwest of the United States. Dry conditions with sporadic thunderstorms are not enough to alleviate drought concerns across the Midwest and the rest of the country. Severe thunderstorms do have the possibility to cause crop damage and reduce corn condition.
The jet stream will continue to flow south out of southern Canada and through much of the northern Plains and Upper Midwest. This will allow periodic shots of cool Canadian air to surge southeast and shunt the intense summer heat away from the region. This battle of airmasses will create a strong and active front where significant widespread precipitation events are expected. Hence, much of this region will likely experience above average precipitation amounts especially as heading south into the Dakotas and the western U.S. Corn Belt.
Drought Concerns: Increasing over sections of the southern Canadian prairies where mostly scattered shower and thunderstorm activity is expected.
Mycotoxin Risk: Sporadic and unpredictable rains across the Midwest are not enough to alleviate mycotoxin concerns. Drought conditions can increase the risk of aflatoxins across dry regions.
Corn Condition: Fifty-nine percent of Iowa corn is in good or excellent condition. Similarly, 58% of Illinois corn is in good or excellent condition. Nebraska has 61% of the corn crop that is rated in good condition or better. Only 43% of Minnesota’s corn crop is rated as good or higher. Well timed rains can maintain crop condition.
Temperature Outlook
Precipitation Outlook
The jet stream will continue to flow southeast out of Canada and into much of the Great Lakes before exiting off the Mid-Atlantic coast. This will keep a persistent trough in place and will allow active weather to continue through much of August as cooler Canadian air clashes with warm and moist Gulf of Mexico air, causing high variations in temperature, which is quite common as we approach late August. Much of this area already has received plenty of moisture this summer and it appears as though this trend will continue.
Drought Concerns: None as the wet July pattern continues into August.
Mycotoxin Risk: Persistent wet conditions can increase the risk of deoxynivalenol contamination.
Corn Condition: Pennsylvania has an estimated 84% of the corn crop in good to excellent condition.
Temperature Outlook
Precipitation Outlook
This region will experience vast temperature differences as an unusually strong jet stream separates intense heat over Arkansas and Louisiana from more tolerable heat over the southeastern U.S. The strong jet stream will also continue to produce plenty of shower and thunderstorm activity, especially east of the Mississippi River Valley. Unfortunately, heading west of the Mississippi into the southern Plains states, dry conditions will dominate. This is a continuation of the intense dry heat that took hold of the southern Plains states in July.
Drought Concerns: Increasing heading west of the Mississippi Delta over Louisiana & Arkansas.
Mycotoxin Risk: Dry conditions can increase the likelihood of aflatoxin in crops.
Corn Condition: Seventy-seven percent of North Carolina’s corn crop is in good to excellent condition.
Temperature Outlook
Precipitation Outlook
A strong ridge of high pressure will continue to be anchored over this region. In turn, the intense heat and dry conditions that dominated much of this region in July will extend well into August. Unfortunately, active fronts will be at a premium as the sinking air under this strong ridge keeps cool fronts from spilling south. The result will be temperatures well above average and precipitation amounts well below normal.
Drought Concerns: Drought conditions will continue to increase over much of New Mexico, Oklahoma and Texas.
Mycotoxin Risk: Sixty-two percent of the Texas corn crop is in good or excellent condition. Corn in Texas is at 63% denting, indicating that harvest season will begin soon!
