"Nether Weather" is an addition to Minecraft that aims to make the Nether feel more like a real place by introducing 3 new weather types to it. You will now encounter lavafalls, storms and heatblasts (which replace storms in the Nether Wastes).

This datapack improves weather and adds new weather conditions, like a sandstorm and other things!

Don't have enough rain or snow in your world because sleeping skips it? Keep it with this mod.

AC&A is a very large mod mainly based around science. It is MOSTLY scientifically accurate, but of course not completely, some things are simplified for gameplay (though not massively) and some things I have not been able to find good sources.
