On Monday, December 2, 2024, what started as a seemingly minor snow accumulation turned into a major disruption around Indianapolis, Indiana. A clipper system, originating from Alberta, Canada, swept across the Midwest and Ohio Valley, bringing light snow that quickly escalated into a chaotic evening commute.
Clipper systems are known for being fast-moving and can sometimes lack notable moisture. In this case, little available moisture in the atmosphere led to minimal snow total forecasts. In fact, many weather apps indicated little to no snow for the Indianapolis area, with chances under 10%. However, as the snow moved in from the west, it quickly began to stick and accumulate, creating hazardous conditions on the roads.

As snow swept through the region, traffic cameras and reports showed that untreated surfaces were rapidly deteriorating, especially on bridges and overpasses. As snow reached the Indianapolis metro area, accidents, slide-offs, and slowdowns became immediate issues. This snowfall arrived right as the evening commute began.
Major highways came to a standstill, with jack-knifed semis and accidents blocking lanes in several areas. Drivers who usually experienced short, uneventful commutes found themselves stuck for hours. Here’s what a few commuters had to say:
Amy: “Took me 3 hours and 45 minutes to get from Greenwood exit 99 to Whitestown exit north of Indy. Normally a 40-minute drive.”
Ashley: “Drove 2.8 miles and passed 4 accidents involving 11 cars. 65N is at a standstill. Insane.”
What was initially a light snowfall quickly turned into a sheet of ice, causing over 136 accidents between 3:00 PM and 10:30 PM across the Indianapolis metro area. Roads were either moving slowly or completely blocked until early Tuesday morning.
While chaos ensued from a public perspective, BAMWX.com meteorologists and the Clarity Weather platform were ahead of the storm. Early Monday morning, BAMWX’s meteorologists issued an hourly forecast around 6:40 AM ET, warning of accumulating snow risks later in the day and likely pavement impacts. As the system approached the Indiana state line, the forecast was fine-tuned and official “Nowcasts” were issued to provide specific timing of impacts, something automated weather apps do not have the ability to create.
Clients of Clarity and BAMWX were kept informed every step of the way, enabling them to take proactive measures.
“I went out and salted,” Kyle with Satisfaction Lawns LLC said. “You guys saved my a**. No one else forecasted snow and we got it. Grateful for the sound advice from you guys!”
Ultimately, this light snow event didn’t have to cause the kind of chaos it did. With more accurate, human-driven weather forecasts like the ones BAM Weather provides, many businesses and individuals could have avoided the disruption altogether.
