When was the Biggest Snowstorm in Indiana in October?
The biggest October snowstorm in Indiana occurred in 1989 between October 18th and 20th. During these two days, an incredible 9.3 inches of snow fell in Indianapolis, Indiana. Perhaps even more surprising was that just a few days before the snowstorm, temperatures in Indiana measured approximately 80ºF. Therefore, the transition from remaining summer heat to a frigid winter was abrupt and shocking.
Furthermore, the areas that experienced the greatest amount of snowfall during the snowstorm of 1989 were central and northern Indiana. On the other hand, much of southern Indiana saw less than an inch of snowfall at the time of this snowstorm. In addition, much of the snow melted following the snowstorm because the ground had already been warm before the drop in temperature.
In addition, the blizzard broke three weather records in Indiana during 1989. For one, the snowstorm of 1989 broke the record for the earliest measurable snowfall in the state. One interesting fact about the record for the earliest snowfall in Indiana is that before 1989, the record had not been broken since 1925.
The other broken records included the earliest full inch of snowfall and the snowiest October on record. In total, only 10 Octobers have reported measurable snowfall in Indiana history. Some of these instances include the years 2014 and 1993, where October saw 0.1 inches and 2.4 inches of snowfall, respectively.
When was Indiana’s Largest Snowstorm on Record?
Indiana’s largest and most brutal snowstorm on record was the Blizzard of ’78, which began on January 25, 1978. The blizzard set several incredible records, including the most snowfall in one month in Indiana at 30.6 inches. Another record set by the Blizzard of ’78 was specific to Indianapolis; the blizzard brought the most snow on the ground to the city at 20 inches.
Furthermore, the Blizzard of ’78 left many people without much-needed resources or medical attention. People were trapped on interstates and roadways, waiting for rescue. Due to the abundant snowfall, medical professionals and emergency task forces couldn’t reach these people by vehicle. Rather, they had to use skis or snowmobiles to rescue stranded travelers.
On January 26th, the governor of Indiana declared a snow emergency that applied to the entire state. Following this proclamation, Indiana law enforcement closed all roadways. Overall, the Blizzard of ’78 had a devastating effect on Indiana. In Indianapolis, snowfall continued for approximately 31 hours, and snow drifts rose as high as 25 feet. Tragically, 70 people died as a result of the Blizzard of ’78.
What was the Biggest Snowstorm in the United States?
The biggest snowstorm to ever hit the United States was the Great Blizzard of 1888, also known as the Great White Hurricane. Between March 12th and 14th of 1888, America experienced its most devastating blizzard to date. Winds rose to speeds of 50 miles per hour on March 12th in New York City. Albany, New York saw 47 inches of snowfall across the two-day blizzard. The location that recorded the greatest amount of snowfall was Saratoga Springs at 58 inches.
Additionally, the Great Blizzard of 1888 crippled the infrastructure and routines of many northern and northeastern states. All forms of transportation were shut down, including the New York City subway system. Furthermore, people were not able to communicate with one another through telegraphs during the blizzard. Many homes and businesses suffered irreversible damage, and more than 400 people lost their lives due to the Great White Hurricane.
