Imagine a pan of water on a stove… got it?
Or a pan of uncooked corn kernels. (We talk more about corn and thunderstorms here!)
This is your challenge: can you tell me where the first bubble will appear when the water boils? Or which kernel will pop first? No?
That’s why we can’t always tell you which cloud will produce a shower, as this footage shows… the clouds scud across the sky, building as they go. Some will drop rain, others will stay flat.
