Beneficial Rainfall Helps Midwest Ratings

Dry weather in North Dakota continues to affect crop ratings. However, the Midwest is seeing stable to improved ratings because of beneficial rainfall.

Good-to-excellent crop ratings for corn and soybeans are down by another 6 percentage points in North Dakota. Ratings for soybeans were up by 5 percentage points in Minnesota due to some significant rainfall. Rain in Ohio improved soybean ratings by 5 percentage points as well. Elsewhere in the Midwest, enough rain fell to maintain stable crop conditions, except in Missouri and far southern Iowa where many locations remain unfavorably dry. Ratings clearly seem to be following the rainfall patterns.

The overall weather pattern during the next six to 10 days will feature a jet stream of varying amplitude over southern Canada and the northern United States. Subtropical high pressure will dominate the southern U.S, East Coast and western Atlantic. This pattern will feature near to above normal rainfall over most of the Midwest, near to below normal in the Plains and mostly below normal in the Delta states. Temperatures will be near to above normal with no persistent heat.

At this time, soil moisture levels are pretty good in the Southern Plains. However, with hot and mostly dry weather indicated during the next seven days, soil moisture will be depleted. This situation bears watching as we head into winter wheat planting season in the fall.

Finally, we would like to comment on the lack of tropical systems in the Atlantic Ocean. In what should be the most active time of the year for tropical systems in the Atlantic basin, there is currently not even a suspect area noted. My theory is there is such a strong, extensive and persistent area of high pressure in the Atlantic and East Coast that it is preventing systems from developing.
