Really nice that you've expanded the range, but I honestly think that my favorites looked better in v1.4.
Calm before storm and Sun breaks through had more contrast/drama back then. Now, they're a bit too blended in and slightly bland IMO.
Also, although I do use content manager, it certainly isn't required unless you want to use the real weather option.
These weathers can be installed and used like any other weather mod.
They could also be used online prior to this, as long as people had them installed.
