How is it possible for it to hail when it's warm outside?

Hailstones are formed in clouds that have strong updrafts. During its ascent, the hailstone acquires new layer(s) of ice as it passes through regions where water droplets have been supercooled. When the hailstone falls, gravity brings it down quickly because it is much more dense than the surrounding air. So it falls too fast to melt ... though it may melt pretty fast after landing, if "it's warm outside."

Think of it this way. The warm humid air at the ground rises. As the air rises, it cools (it's called adiabatic cooling) due to lowering air pressure. As the air cools, it's ability to hold moisture reduces. The air become saturated and then water vapor condenses into liquid water. It's density is not yet great enough and the still rising air currents carry it higher where it is cooled further until it freezes and makes an ice ball. Depending upon the velocity of the rising air and the density of the ice ball, it can either drop to the ground as small ice pellets before it can melt, or it can gather more water on its surface and then be carried upwards again and freezing one ore more layers of ice on the now larger ice ball. At some point in time, the ice balls fall and hit the ground as hail. They fall faster than the warmth can melt and stay solid.

Ask a liberal and I'm sure they'll say it has something to do with Globull warming, er, I mean climate change. Everything bad is caused by Cliimate change, or of course Trump. SMH

because it is a lot colder up in the sky where clouds are so a raindrop that bounces around due to static and freezes may not melt completely when it gets to the ground

It's cold in the stratosphere is why. If you slice a half stone into 2 pieces you may be able to see the different layers of ice.

It's very cold high in the sky where the hail forms, and presumably the hail falls before the warmer lower air melts it.
