When Guesswork Became a Risk

Turns out having a thunderstorm sweep across the track not only washes out the racing, and soaks fans, but can put everyone in harm’s way. In 2012 at Pocono Raceway, a lightning strike turned deadly, ultimately leading to NASCAR implementing its now-standard lightning policy: if a strike occurs within eight miles of the track, everything stops for 30 consecutive minutes without a lightning strike within the same 8-mile radius. No exceptions.

Annoying? Sure.

Necessary? Absolutely.

And it also forced a realization: guesswork wasn’t going to cut it anymore.

Turning to Data for Answers

So how does NASCAR know that lightning is indeed within 8 miles, and how can they be certain when weather could impact a race days before the event? It’s because among all the Official Partners in the sport, there is one that provides a very vital, valuable service. The Weather Company, a simple name for a company that does a great deal to ensure that if Mother Nature comes calling at a racetrack, NASCAR will know all about it, and well in advance.

How? Data.

Lots of it.

Today, the sport relies on real-time forecasting from The Weather Company, feeding NASCAR a constant stream of hyperlocal data designed to answer one very specific question: not if weather is coming, but exactly when.

The difference was on full display at the first race of the 2026 season, the Daytona 500.

Daytona Proves the Model

With severe weather approaching, NASCAR made the call to move the start of this year’s Daytona 500 up by an hour. More than 100,000 fans packed into Daytona International Speedway watched the entire race run to completion, and just as importantly, had time to get to their cars before the skies opened up.

That decision didn’t come from instinct. It came from data.

The Ringmaster Behind Race Day

Orchestrating how that information turns into action is Tom Bryant, NASCAR’s Vice President of Race Operations, the closest thing the sport has to a ringmaster for its traveling circus. He’s not the one making the final call, but he is the one making sure that when the call comes, everything that needs to happen actually does.

“That is a call our senior leadership makes,” Bryant said. “It impacts not just the 100,000-plus fans at the track, but millions watching, sponsors—so many stakeholders.”

His job is to ensure the machine is ready to move when that decision is made.

And increasingly, those decisions are shaped long before race day.

“We have a standing group that meets… and we involve the Weather Company forecaster,” he said. “We talk through it and make decisions well in advance so everyone has time to adjust.”

And the data provided by The Weather Company informs NASCAR and helps those decisions.

“Our approach now is that weather intelligence is woven into the planning process from the very beginning,” Bryant said. “We don’t build a schedule and then see how it lines up with the forecast. We take into account what’s coming.”

At Daytona, that meant acting early.

“We knew weather was inbound,” Bryant said. “They were spot on. We were able to be proactive instead of reactive, get the race in safely, and allow fans to get back to their vehicles before the weather got tough.”

That last part matters more than anything.

Because while a delayed race is inconvenient, a dangerous situation is unacceptable.

How the Forecast Gets That Precise

Behind that decision-making is a level of forecasting that goes far beyond what fans see on their phones.

“We’re forecasting at an hourly granularity out 15 days,” said Matt McCrary, a meteorologist with The Weather Company. “Within three to five days, we have a pretty good idea if there’s going to be disruption. And as you get closer, that confidence increases.”

Closer, in this case, means very close.

“I don’t need to know it might rain Sunday afternoon,” Bryant said. “I need to know within five to ten minutes when it’s going to start… We’d love to know within five seconds.”

That level of precision is what turns weather from a surprise into a strategy.

Using a mix of global models, proprietary data, and input from roughly 150 meteorologists, along with nearly 190,000 personal weather stations across the U.S., The Weather Company can narrow forecasts down to minute-by-minute windows and highly specific locations.

“We take data from every source you can imagine,” McCrary said. “Global models, regional models, proprietary models, all overseen by meteorologists.”

“In many cases, we can get down to about five minutes,” he added.

At a superspeedway, that level of precision matters, both in timing and location. A storm can hit one end of the track while the other stays dry, creating conditions that are as unpredictable as they are dangerous. It’s known as hyperlocal forecasting.

“We can get very granular spatially,” McCrary said. “Generally speaking, the data sits on a one-kilometer grid and then we have the ability to downscale a little bit there.”

And the forecast doesn’t sit still.

“It absolutely changes,” McCrary said. “The atmosphere is dynamic. You can have perfect conditions, and 15 minutes later, storms rolling in.”

But it is, after all, a forecast.

“Weather forecasting is an imperfect science,” McCrary said. “We’re providing the best information at that moment in time.”

Which is why NASCAR doesn’t just check the weather, it builds entire race weekends around it.

By Tuesday morning of race week, Bryant said NASCAR has already reviewed multiple forecast iterations and is discussing potential adjustments.

The Cost of Getting It Wrong

That early planning isn’t just about getting cars on track. It’s about managing a logistical operation that spans thousands of people and millions of dollars.

“If we move a race to Monday, I’ve got to change flights, hotels, truck schedules, deliveries,” Bryant said. “There are so many secondary and tertiary effects. It’s enormous what it could cost.”

That ripple effect touches everything from broadcast windows to local law enforcement to the next race on the schedule.

Eliminating the Surprise

Which is why avoiding surprises has become the real objective.

“For an operation, you’re only as good as the intelligence you have,” said Bryant, a retired U.S. Army lieutenant colonel. “This is a critical component of our planning.”

In other words, NASCAR still can’t control the weather.

But it’s getting seriously close to outsmarting it.

And these days, the difference between a completed race and 100,000 soaked fans might come down to one thing: knowing exactly when the sky is about to blink.
