In a recent meeting with regional climate and natural resources officials, Dennis Todey, the director for the U.S. Department of Agriculture’s Midwest Climate Hub, emphasized that Iowa is entering the new year with dry soil and that it is unlikely soil conditions will change quickly. Since more rainfall is needed to address Iowa’s dry soil there is an increased chance Iowa will continue to be dry into the spring. 2020 was the 36th driest year out of 149 years on the record, leaving around 61% of the state at some level of drought.
Iowa’s drought conditions can likely be attributed to La Niña conditions which usually indicate a greater chance for colder temperatures and average or slightly above average precipitation. La Niña weather patterns develop as colder sea surface temperatures occur in the Pacific around the equator as part of the El Niño – Southern Oscillation (ENSO). These ocean conditions can result in warmer winter temperatures for the southeast U.S, and colder winter temperatures for the north west.
