Drought conditions are likely to develop over the southern half of the state in August as the month starts with abnormally hot days with little chance for rain, according to the U.S. Drought Monitor.
What started as a portion of the state being abnormally dry or in varying degrees of drought has expanded to more than half of the state. It’s the first time the dry area has been that large since April. The latest Drought Monitor report on Thursday showed an expansion of severe and extreme drought in northwest Iowa and the extension of abnormally dry conditions across much of southern Iowa.
Southwest Iowa previously led the state in available soil moisture, according to the U.S. Department of Agriculture. In early June, about 96% of its topsoil and subsoil had adequate or surplus moisture. As of Sunday, about 27% of topsoil and 36% of subsoil had adequate water for crops to grow.
The National Weather Service issued a heat advisory for Tuesday afternoon for the western half of the state.
Last week, the state averaged temperatures of about 3 degrees cooler than normal with abysmal rainfall. Much of the south had no rain, and the highest reported rainfall accumulation was .89 inch near Churdan.
The state’s corn was rated 76% good or excellent, down from 80% the previous week. Soybeans were rated 73% good or excellent, down from 75%.
