You do not have to travel far to find extremely high totals in eastern Kansas and southern Missouri with amounts upwards of 20 inches! The forecast looks to continue this pattern, but there will be chances for rain in Iowa.
Rain has been very difficult to come by this July for most of the state. The featured chart displays an analysis of precipitation percentage of average for the first 15 days of July. Most of the state is shown in the 0 to 20% range with the actual accumulation labeled on the map. Des Moines has only reported six hundredths of an inch, which is the driest start since 1975. The forecast continues the dry weather with temperatures in the 90s for the rest of the week.
After having plenty of rain during the spring season and June, rain has been difficult to come by for the first seven days of July. The statewide total so far is second driest behind 1940 according to IEM calculations. Some heavy rainfall has fallen in extreme northeastern Iowa this morning and more chances of rain are in the forecast for this week. The black line on the chart shows the normal accumulation of nearly an inch and getting about an inch of rain per week is about normal for most of the summer.
