About a dozen new weathers and the climate for the Commonwealth is much more stormy, gloomy, and polluted. Clear skies still spawn sometimes. Sleeping for 24 hours usually gets rid of it for a while. If you start a ng the default clear weather still spawns first.
This is a HUGE step up from 1.0. Less beauty and vapor-wave and much darker / nuclear / polluted.
There are variations of some of the weather types. The third impact weather has one with a clear horizon and bright lighting and one variation with red saturated fog and lighting. Some variants have thunder and rain but can spawn without precipitation as well.
This mod will go up to 2.5. The final version will feature more weathers for the Commonwealth and add the weathers to Nuka World and Far Harbor.
My PC sucks and this will likely look a lot better on yours than mine lol.
