Gov. Scott Walker and three of his cabinet secretaries plan to tour a couple drought-stricken farms in southern Wisconsin on Friday.

Walker will be joined by Ben Brancel, secretary of the Department of Agriculture, Trade and Consumer Protection; Cathy Stepp, secretary of the Department of Natural Resources; and Ted Nickel, secretary of the Department of Insurance.

Walker plans to view drought damage from the air and also take ground tours of farms in Burlington and Dodgeville.

The tour comes after Walker on Wednesday expanded a drought emergency declaration statewide. The U.S. Drought Monitor on Thursday also upgraded the drought from severe to extreme across southern Wisconsin.
