This mod is the stripped down version of Weather Redux. It provides only darker nights to the vanilla game, and does not include any new weather patterns.
None of the new storms from the full version of Weather Redux are included in this mod. Storm parameters are closely aligned with vanilla; storm durations are slightly longer but with more variability. This creates a more natural flow of the weather than the default game. The nights are very dark. This mod does not adjust the PipBoy light in anyway, so you are free to select which Pip-Boy mod (if any) you want to use.
If you are interested in additional storms and more intense weather patterns like dust storms and plasma storms, check out the full version of Weather Redux.
