Prolific Hailer

Posted: 10 Jul 2021 07:04 AM

A super cell thunderstorm developed into quite the prolific hail producer early afternoon on Friday with the featured map combining maximum estimated hail size by the NOAA MRMS project and available NWS Local Storm Reports. This map is zoomed in on about a four county region including Des Moines and to its north and west. The largest report received so far is 3.25 inches from Windsor Heights (suburb of Des Moines). The MRMS product aligns nicely with the received reports with a caveat being that this storm was right over-top the Des Moines NEXRAD location in NW Polk County, so algorithms may have struggled some. The "generate plot" link for this feature takes you to a viewer of the Local Storm Reports for this event.

Good = 14
Bad = 2
