Continuity mistake: When Jo's truck lands in the road, right after which Jonas' crew drives by, if you look quickly, you can see that the driver side (the truck was upside down) window is gone. Yet, when Jo goes to get her backpack out, she has to kick that window out. (00:35:25)
Continuity mistake: When they are at the drive-in movie "The Shining" is showing just as he sees the two girls, but five minutes later the guy is knocking down the door with an axe, these two scenes occur an hour apart. (01:05:45)
Continuity mistake: When they make their pit stop at the BBQ diner Bill is outside with Dusty and says, "we're going green". The sky is dark and green. When Jo comes out and they're ready to go a few minutes later, the sky is almost sunny and it's suddenly partly cloudy. (00:25:10)
Continuity mistake: When Bill and Melissa go out to get the divorce papers from Jo, we see Bill pull his truck up with Rabbit and Allan's truck (hood up) in the background. We see it closer up when Bill asks Dusty, "Where's Jo?" But when the scene comes back to Bill and Dusty and then shows Melissa, Rabbit, Allan and the truck have disappeared. When Dusty is holding Melissa's hand and walking to sit in his chairs, Rabbit & co. are in the background again.
Continuity mistake: When the telephone pole falls on the bed of Paxton's truck, the pole dents the bed. In the scene before the pole falls, there is a dent on the bed.
Continuity mistake: As Bill and Jo pass the camera position, the red lights on Dorothy are flashing. A moment later, Bill actives Dorothy, including the lights.
Continuity mistake: At the beginning of the drive-in scene Jo and Bill give each other a long look. During this you can see that Jo passes the same Pepsi sign twice.
Continuity mistake: When Bill & Jo leave the aunt's house in the red truck, it shows the truck has a back sliding window - the next shot there is no back sliding window.
Continuity mistake: When Bill is walking over to see Jo for the first time, he passes Joey working on the hood of a truck that was previously shown in front of the blue Doppler van and next to the green tractor. Throughout this sequence, this taupe/brown pickup with camper flops back and forth between the two places. Lawrence finally drives it off.
Continuity mistake: In the first few seconds of the movie, there's a landscape shot of a fence. Right in front of the fence there's a little piece of grass blowing in the wind, and it's just so obvious that they looped the 1 second to make it last 5 seconds, because the grass keeps jumping back and forth. Minor but annoying.
Continuity mistake: After the pitstop, when Jo's team and Jonas's team have the encounter, Jo's team takes off to chase another tornado. When we hear Dusty holler, "Hey you guys, woohoo," we see Jo reach for the CB and dial from channel 22 to 18. But when Bill says, "Shi_," Jo reaches down to adjust the CB and the channel showing is 39.
Continuity mistake: At the beginning, when the guy comes back to have Jo sign the divorce papers, He says "you missed one", and you can see a red tab on the paper that she missed. In the next scene it's gone and in the next it's back again.
Continuity mistake: After the first twister they chase, Jo's hair is covered in mud and dirt. Then minutes later in the red truck her hair is clean and fixed nicely.
Continuity mistake: When all of the crew are heading to the F5 tornado, in the truck, you can see that the dog is in the front of the truck and at the same time, under a table on the back of the truck.
Continuity mistake: When Bill is going over the divorce papers, he comes to the page missing Jo's signature. It only has one red arrow near top right. When he hands it to Jo, she starts looking at it, then flips up page to look at others, and the missing signature page is a completely different page with two red arrows, one toward the top and another, on the right, toward the bottom. (00:12:25)
Continuity mistake: In the scene immediately before the gas tanker blows up in front of the truck, the passenger window of the truck is wide open. As the truck clears the explosion, the window is closed.
Continuity mistake: When the red truck is driving to the tornado where the sensors spill, the scenery and pavement change between shots. First, they are driving down a road with trees on both sides. Then, they are driving down a large empty area where you can see the the horizon. Finally, they drive into a valley with forests on both sides. And this happens in a matter of seconds.
Continuity mistake: During the last tornado scene, one of the team members says "they're going to punch the core" as Bill and Joe turn right off the road towards the F5. If you look ahead of their truck above the cornfield there is no sign of the F5 they turned apparently towards.
Continuity mistake: When Jo and Bill are traveling in the ditch during the tornado they show them hitting the bridge from the front and then they change the angle to the passenger side (Jo's side) and they show them hitting the bridge again.
Continuity mistake: When they are driving in the Dodge Ram, the window gets shattered at one point, and then they literally drive through a house and then as they come out, the window is intact again.
Suggested correction: The scale back then was based on the size of the tornado, it's only more recently it is based on damage. So during the time of the movie, the scale was being used correctly for size not damage.
The Fujita scale was introduced in 1971 and was in use during the 90's when this film came out. The Fujita scale measured the damage caused by a tornado to man-made structures after ground or aerial surveys, it was not a measurement of tornado size (an F5 tornado is a tornado that's rated on the Fujita scale). It is true the Fujita scale was replaced by the enhanced Fujita scale in 2007, but that was only to align the ratings to the damage better, it did not change rating tornadoes from size to destructive powers.
