Showers and a few thunderstorms returned to the state Monday evening. Of course having such storms is certain what one may expect for this time of year. The featured chart displays a NEXRAD composite for each of the past 23 years at 7 PM over Iowa. It is amazing to think we have such a long term record of NEXRAD data built-up now. RADAR data did exist prior to 1995, but the availability, formats, and legacy platform make it somewhat difficult to utilize today.
