While a quick hitting system Friday evening did not bring that much snow, it was certainly very impactful and warrants an IEM storm accounting map. This system prompted the National Weather Service to issue a number of Snow Squall Warnings, which is a special product to cover temporary white-out conditions due to falling snow and strong winds. For a number of NWS Offices, this was their first issuance of such a warning (this warning type is relatively young compared with others). Anyway, actual snowfall totals were an inch or less over far eastern Iowa. The Snow Squall Warning polygons are shown in the purple color and conditions warranting these warnings were even worse over Wisconsin and Illinois last evening.
