Wow i actually know this....The bottom one is a graph on Air pressure ( In Millabars ). The higher the pressure is, the few clouds and storms are...the lower the pressure..the bigger chance for thunderstorms. That graph line is like a wave...pressure keeps going up and down, up and down. Higest is 1018mb and the lowest is only 1015mb? Thats a pretty high range of pressure. Where do you live?
