Yesterday's US Drought Monitor update painted a deepening drought situation for the state with the entire state now analyzed in some level of drought. While long term dryness continues to be an issue for some parts of the state, recent dry weather has been common for the entire state. The featured chart illustrates this by showing a time series of two week trailing departures of average temperature and precipitation for an areal averaged Iowa value. The arrows connect this metric evaluated every seven days and you can see after starting off with a positive precipitation departure for the end of July, we have spent the entire time since below average for precipitation and the most recent plotted metric has the dryness as the most anomalously severe level.
