Remembering 1974 Super OutbreakApril 3rd, 2014 at 3:10 pm by Chad Evans under Chad's WLFI Weather Blog
On this April 3, 1974 a violent, long-lived HP supercell produced large, violent, multi-vortex tornadoes from Decatur, Illinois to Ontario. All along the path, sporadic large hail was produced, as well.
Damage began near Rainsville with rapid formation of F3 tornado. Tornado lifted & new, violent F4 rapidly developed west of Brookston, barely missing Chalmers, before hitting Monticello squarely. Significant damage continued all the way to Talma & near Rochester.
Violent tornado formed at triple point of system.
Another long-lived supercell tracked from Boone to Tipton counties with two F2 tornadoes.
Below are two pictures taken of supercell moving toward West Lafayette at Purdue University. You can see an obvious wall cloud in first image. Second image is gust front on leading edge of supercell. No tornado was confirmed from this particular storm. The really violent one was just north of this particular supercell, it appears.
Fish were reportedly sucked out of the Tippecanoe River & strewn in fields & railroads ties were picked up & thrown long, long distances by the Monticello tornado.
Any stories of your experiences regarding experiences from this outbreak are appreciated!
