Some much needed rainfall

Posted: 30 Mar 2012 05:57 AM

A thunderstorm complex fired to our southwest Thursday evening and rolled into Iowa overnight dumping some much needed moisture over a good portion of the state. The featured map presents estimated rainfall totals from the NOAA NMQ project for the 12 hour period prior to 6 AM on Friday. Sometimes these estimates can be a bit overdone due to hail contamination, which causes radar based precipitation algorithms to over estimate the amount of water reaching the ground due to the highly reflective hail stones to radar.
