'17-'18 Winter Storm #1

Tags:   winter1718  
The IEM generates snowfall analysis maps based on NWS COOP observations, Local Storm Reports, and CoCoRaHS reports. The arbitrary requirement for classifying these events as storms is for somewhere in Iowa to receive 2+ inches of snow or to have significant impacts from ice and/or blowing snow. So far NE Iowa has some isolated totals of two inches, so we have our first "winter storm" of the season. There have been other light snow producers in the state this season, but only have seen an inch or less reported. Look for more maps like these as the season progresses and the "Winter Storms of 2017- 2018" link on the homepage will bring you to a page showing all these maps.
