Before 1950 the record is Thomas P. Grazulis’s list of significant tornadoes: those rated F2 or stronger, and weaker ones that killed somebody. 8 of them crossed Vermilion County, killing 27. They are not in the figures above, which are SPC's from 1950.

Significant tornadoes only

Grazulis listed tornadoes rated F2 or stronger, and weaker ones that killed somebody. Most tornadoes are weaker than F2, so the list holds a fraction of the tornadoes that happened.

The early years are thin

A tornado is on record only where somebody saw it and wrote it down. The count rises through the 1800s with settlement and newspapers, not with the weather.

Rated from accounts

Grazulis rated each tornado decades later from newspaper reports, Weather Bureau records and local histories, not from a damage survey.

The tracks are reconstructed

Tornado Archive drew each path through the places Grazulis names, most often as a straight line from the first to the last. A track can miss a town it hit, and a tornado with one named place is a point. The counties are today’s.

A separate record

SPC’s database, from 1950, counts every confirmed tornado of any strength. The two are kept apart on every page and never added together.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
