Daytime heating is a major contributor to afternoon thunderstorms. The
increased sun means increased temperatures making the air rise ... as the
air rises the moisture in that air form clouds .. the more heat the more
convection the bigger the clouds.... of course you need moisture in this
process so the more moisture you have the greater chance of the storm
becoming bigger .. bigger storms more unstable. Many T storms will setup
along some mountains in the afternoon, where you not only have solar heating
but orographic land features make that parcel of air go up and thereby
making a cloud. Things that make the storm become unstable can be a
combination of many things .. like more moisture, heat, a different and
colder airmass mixing with the warmer, moister air.

Can daytime heating cause thunderstorms and how can the storms become
severe?
