SOUTH DAKOTA(WNAX)- Dry conditions are expected to continue across much of the northern plains into mid-winter.

South Dakota State Climatologist Laura Edwards says the drought impacts are being seen on the Missouri, Mississippi and Ohio Rivers.

Edwards says cold temperatures and dry ground could cause some other problems.

Edwards says they also expect the La Nina to linger into late winter.

The worst of the drought conditions have settled into areas of western Iowa, eastern and central Nebraska and much of southern South Dakota.
