A week of above-normal temperatures and little rainfall has taken a toll on topsoil moisture in the Northern Plains and parts of the Midwest. The overall impact of this drier weather will be to force corn and soybeans to send root systems deeper to reach the subsoil. This will actually benefit crops. The impact of this weather would have been more of a negative if corn were pollinating or soybeans were filling. The crop negatively impacted is winter and spring wheat in South Dakota. The winter wheat crop is filling and the spring wheat crop is heading in this state. This hot and dry weather will have an impact on production. The spring wheat crop elsewhere in the Northern Plains has yet to head out, so the impact of this hot and dry weather has been limited. The outlook for the Northern Plains and Midwest is quite favorable. We expect to see frequent episodes of scattered showers and thunderstorms in both areas during the next week, along with cooler temperatures.

Drier weather in the Southern Plains during the past week favors maturing winter wheat and the increasing harvest which is just getting underway in Kansas. The outlook calls for near to above-normal temperatures and near to below-normal rainfall during the next seven days, which will allow for generally favorable harvest conditions.

Adequate topsoil moisture across the Delta and Southeast states and no severe heat favors pollinating corn and developing soybeans.
