The parent storm of these particular tornadoes that night took a hauntingly similar path as a very well-known tornado in the area's past. It's been identified as the worst tornado in the United States....The Great Tri-State Tornado 1925. "Worst" is used when defining for longest track, longest duration and deadliest. The story and finer details of this particular tornado have been researched for decades. In 2013 the most recent paper was published and is what I consider to be a "final" report concerning this horrific tornado. Written by some of the best meteorologists in the scientific community, years of collecting data town to town in the path, has in fact determined the validity of one complete and devastating track. Their researched damage path of the 1925 Tri-State is shown in the map below.

The weather pattern was slightly different and the time of day probably made the biggest difference between these two cases. Similarly these two storms traveled along a moisture boundary across Southern Illinois as an area of low pressure surged NE toward the Great Lakes. The Great Tri-State likely thrived better with the support of diurnal heating of the day. The February 28th storm was not diurnally based and developed during the dark hours of the evening.
