A slow-moving low-pressure system delivered precipitation from the Rocky Mountains through the central and southern Plains and into the Corn Belt and mid-South over the weekend, delivering what some farmers called a “billion-dollar rain” in areas where rainfall ranging from two to six inches was a welcome sight, especially where drought has been a dominant weather issue. The drought continues to grow in severity in the far southern Plains and Southwest, while the northern Plains — where the moisture deficit is growing — also missed out on the weekend precipitation. As the system moves east, the central and eastern Corn Belt will get much-needed rainfall as parts of South Dakota, Iowa, Minnesota, Nebraska, Wisconsin and Illinois start the week with snowfall and winter storm conditions. Late Monday, the next system that could deliver widespread precipitation across the Plains, Midwest and mid-South will begin moving east from California.
