The Accumulated Winter Season Severity Index (AWSSI for short) is a new index that was created to objectively determine how extreme the winter season has been. It is not linked to a specific climatological or astronomical season but is defined to start and end when a specific set of conditions has been reached, and then it accumulates points based on how often discrete categories of temperature and snow are reached for each of 52 locations around the United States. You can read more about it at https://mrcc.isws.illinois.edu/research/awssi/indexAwssi.jsp#info.
Based on calculations for this year, our winter across the eastern US has been mild, except for the mid-Atlantic where the AWSSI was rated as average.
