But he finally admits that he will never complete this task. So he decides to make more air, water, and heat. The class lands inside the bus and Keesha tells Ralphie that despite making clouds and rain, he still needs to make the thunderstorm. The ice crystals suddenly melt, and the class is now in raindrops. They suddenly transform into snowflakes made up of ice crystals and slowly fall down from the sky. Frizzle tells them that clouds are made up of tiny water droplets and they end up making a cloud. They then change into tiny water drops and hold hands to form a circle. The bus transform into a spray bottle and sprays them outside in the sky. When Dorothy Ann tells him that he needs to make water, he decides to use all three of the elements of weather to transform the class into water. When Wanda asks Ralphie if he can make clouds, he tries to find which button to press to do so. He then decides to put it for the next chapter of his comic strip: 'Weatherman and the Updraft Riders'.

Frizzle calls that a good example of a small updraft, but Tim adds one has to be bigger than that. Phoebe guesses it as a comparison to heat rising out of a toaster. Frizzle states that he has made an updraft, which is warm air that blows up rather than sideways. So Ralphie decides to combine the air with heat to make the thunderstorm and ends up propelling the bus higher in the air. Moreover, after the warm air rises, more air must replace it with cooler air, thus creating wind. When Wanda asks what makes the wind, Keesha responds by explaining that air and heat combined do so, for the sun heats the earth which heats the air which causes the warm air to rise. But Keesha refuses to refer to him as Weatherman, for he has yet to create the thunderstorm. The class hops back onto the bus and gives Ralphie acclaim for his creation of wind. Frizzle adds that different combinations of air, water, and heat make different kinds of weather. When they notice a thunderhead eclipsing the sun, Dorothy Ann informs that weather is different in different places. Frizzle and the rest of the class in the sky. So he transforms himself flat to float with Ms. She tells Ralphie that he should combine the three elements of weather (air, water, and heat) to make one new type of it. Frizzle is the first to float back down inside the bus and changes back into her normal human form. Frizzle continue to float in the air, Tim writes the first chapter of his comic strip: 'Gone with the Wind'. The rest of the class follow suit and Ralphie realizes he made a huge mistake.Īs the class and Ms. Frizzle becomes as flat as cardboard and flies to the sky. When Ralphie uses the steering wheel, Ms. He then pulls a lever, which sends the bus flying in the air and causes the ceiling to flap open. They enter the bus and Ralphie, irresolute of what he has to do, presses a red button, which turns on the fan behind the bus. Ralphie tells the rest of the class that for his first power, he will make a thunderstorm. Tim decides to write this in his comic strip called 'The Adventures of Weatherman'. Ralphie follows Liz to warm up the bus outside and emerges through the door dressed as Weatherman. Frizzle decides to take them on a field trip to explore weather. When the class begin to argue whether it's water, air, or heat that makes the weather, especially when Keesha and Ralphie get into an angry altercation about Weatherman, Ms.

Ralphie expresses the wish to make a thunderstorm, and creates the alter ego of Weatherman.

Walkerville is going through a massive heat wave, the temperature reaching 99 degrees Fahrenheit (or 37 degrees Celsius, as Phoebe adds).
