The publication of the US Drought Monitor update for this week is currently in progress. It considers the precipitation that has fallen up to Tuesday morning of each week and is released on Thursday. The featured map displays the combination of the current drought monitor issued last week and the seven days of precipitation that roughly fell since its issuance. The hatched areas on the map are the drought monitor categories. In general, there was little help for the rain that did fall last week for the driest areas of the state. Some localized dry places did pick up an inch or two, but that amount of water only meets current intensive crop demands. The most significant and flooding rains fell almost completely away from the dry areas.
You don't have to drive very far from Iowa to find areas with significant precipitation deficits. "D3" classified drought areas are currently depicted in Central Missoura, Western Nebraska, and Northern Minnesota. Only extreme portions of SE Iowa are depicted with any dry conditions. Rainfall this weekend should help alleviate the dryness in Missoura and mostly miss Iowa as the system tracks to our south.
