The just released US Drought Monitor continues to paint a dry picture over western Iowa with a considerable portion of that area analyzed in "D0" drought status. The featured map presents the combination of the current drought monitor and the past 30+ days precipitation departure. The Drought Monitor blends a number of short and long term indicators along with reported impacts to produce the analysis, so there is no one-to-one relationship with the map shown. The drought situation continues to be of concern as warmer weather, developing crops with increased water demand, and continued lack of considerable rain in the forecast look to degrade the drought situation further over the coming weeks.
