Centennial Honors College Western Illinois University Undergraduate Research Day 2014 Poster Presentation 2011 Groundhog Day Blizzard Jeff Draughan Faculty Mentor: Jongnam Choi Geography This study examines a Midwest blizzard on January 31 - February 2, 2014, known as the "Groundhogs Day Blizzard". This study shows why and how this storm developed into such a big and powerful blizzard and how this storm is different from other winter storms that are not as strong. Integrated Data Viewer (IDV) is used to acquire, analyze, and display surface maps, upper air conditions, and radar/satellite imageries. Archived data from the NCEP/NCAR Reanalysis Project website and the NOAA Comprehensive Large Array-Data Stewardship System (CLASS) were used. This project compares atmospheric conditions during the "Groundhog Day Blizzard" and those of an average snowstorm. The preliminary results show that the Groundhogs day blizzard formed from the phasing of an Alberta Clipper from the northwest and a low pressure system from the pacific. Findings from this study are useful because winter storms are very disruptive in terms of travel and a better understanding of what makes one stronger than another is beneficial to make a better forecast on future snowstorms.
