Through years, months, days, hours of research, the library of data at home & here at work has allowed me to find the top 10 longest durations without a severe weather event or outbreak in our viewing area since 1851.
There were not as many observers back a century ago or even half a century ago, but it is amazing how well severe weather was documented in newspapers, diaries & in the archives of the U.S. Weather Bureau (National Weather Service) & the extreme detail our ancestors put into reports. Photographs reveal very much, as well. Some of the reports are much more detailed that what you would even find now!
Severe weather status would reach "event" threshold if at least three counties report a total of more than five severe weather/damage incidents or at least one tornado.
1. April 28, 1870-December 23, 1871 - 1 Year, 239 Days
April 28, 1870: 3" diameter hail struck Rensselaer around 6 p.m. with widespread damage to trees, plants, roofs reported. Many windows were broken out. Heavy wind damage was reported just north of Otterbein & at 6:30 p.m., a significant severe t'storm struck Lafayette.
Numerous trees were toppled or otherwise damaged & a lot of substantial structural damage occurred. Here are just a few of the many reports of damage to buildings in the Lafayette area according to the Lafayette Courier at the time: The west wall of Mrs. Barbee's building, on Columbia street, lately destroyed by fire, was blown over, burying under it the one-story frame grocery store and dwelling of John Lynch. The escape of the family was providential, and had it not been for Mr. Toberty they would have been buried in the ruins. He saw the danger and gave the alarm just in time for the family to escape. The house was totally demolished, and the household furniture was too fine for kindling wood...............
December 23, 1871: Damaging tornado struck the heart of Lafayette with damage to most buildings in the downtown area & point northeastward. Tornado was described an eyewithness as looking like a twisting corkscrew. Two people were injured.
Small pieces of the account:
It came from the southwest, traveling toward the north-east, and was not more than two squares in width. The first building affected was the Falley Block, corner of Fouth and South streets, the rood of which was raised, on the south side, fully two feet, but which fortunately fell back and resumed the proper position. The roof of Mrs. Peter Vall's new building, on Columbia street, near the corner of Fifth, came next in order, the tin upon which was rolled up like so much paper, though it was not blown clear off the building. The Second National Bank building, north-east corner of the Public-square, better known as Reynold's store front, came next in the path of the wind. The tin covering of the whole roof was blown off, together with the timbers and sheeting of the entire southern half of it.

380 killed & nearly 1300 injured with at least 56 deaths in Indiana & one tornado tracking 100 miles over northern Indiana to Ohio.

May 12, 1888: Tornadic storm with damaging large hail up to hen egg size with tornado near Freeport, Illinois evolved into damaging wind event that produced widespread wind damage across northern Indiana, including Jasper, Pulaski, Fulton, Miami counties in our area. 48 train cars were blown off the tracks on the Nickel Plate Railroad & trees completely blocked the L. E. & W. Railroad. 150 telegraph poles were snapped.

A strip 1 mile wide & 10 miles long saw very heavy wind damage in Montgomery County east & southeast of Crawfordsville. Called a "Cloud-burst" by the U.S. Weather Bureau at the time, it appears to have been a wet macroburst. Barns were destroyed, crops flattened, roofs were damaged or partially removed & damage to timber & wires was impressive in the zone.
The rain was very heavy & some fields were said to have the taken the appearance of a "vast lake". White County was reportedly hit hardest by the flooding rainfall with roads & crops washed away.
