A significant severe weather outbreak occurred in our area on April 30, 1962. 1 person was killed & at least 14 people were injured. Total damage in the area (inflation-adjusted) was +$5 million.
The U.S. Weather Bureau surveys at the time reported that the damage in eastern Illinois to Indiana was +90% from significant straight-line winds & not tornadoes.
Outbreak began in the midday to afternoon with surface low in Illinois & strong surface cold front & passed through our area in the 2-3:15 p.m. time frame.
Temperatures ahead of the low & front surged to unseasonably warm levels well into the 80s to around 90. Chicago reached 88, Fort Wayne & Indianapolis 87 & highs reached up to 88 in the viewing area.
Even at 1 a.m. on May 1, the matured squall line was still going & lined up from Toledo, Ohio to Houston, Texas.
In this significant severe weather outbreak winds gusted 60-110 mph across central Illinois with isolated downburst gusts to 135 mph. Winds gusted +100 mph in the viewing area. The line of storms brought widespread substantial to significant wind damage & 4 confirmed tornadoes.
An F2 tornado tracked through Newton County, while another F2 tornado in Jasper County did ¼ million dollars in damage. An F1 tornado in White County also did ¼ million dollars in damage. An F1 tornado roared through Miami County, while winds gusted to 85 mph in Cass County & 80 mph winds struck Warren & Fountain counties. Outside of our area, an F3 tornado injured 49 people in St. Joseph County.
However, the worst of the straight line wind damage was in Benton & White counties in a swath of 95-120 mph.
Winds likely peaked with macrobursts around Dunnington, Atkinson & Templeton to north of Montmorenci to near Chalmers where multiple steel, high-voltage towers were toppled & crumbled by +100 mph winds. Multiple barns were also destroyed. Several farmhouses saw significant roof damage. Damage continued eastward to Cass & Miami counties. Even at the Fort Wayne Airport, a wind gust of 89 mph was measured. Multiple airplanes nearby were lifted up to 50' in the air. One was destroyed.
A similar wind situation occurred August 15, 2007 when intense downburst (embedded in 3- to 5-mile wide swath of +80 mph winds that tracked more than 70 miles) in southeast Porter County caused the same type of damage. NWS Chicago indicated in their storm survey that winds peak at 100-120 mph.
