The Accumulated Winter Season Severity Index (AWSSI) is some ongoing research lead by Barbara Mayes Boustead of NWS Omaha that attempts to quantify and compare the severity of the winter season. It takes into account daily temperatures, snow depth, and snowfall. The higher the index value implies a more severe winter season. The featured chart is from the AWSSI website and shows the total this year for Des Moines near the lowest accumulation to date on record for the site.
