Weather Redux for PlayStation 4 is actually two mods in one.
One part of the mod delivers some changes to the storms that occasionally appear in the wasteland. Storms will now last longer and rain, fog, and mist will popup a little more frequently. Radstorms won't appear as often.
The mod also delivers some new storms including a gorgeous Plasma Storm, duststorms, and an intense thunderstorm.
The other part of the mod makes night's darker. Much darker, sometimes to the point that you can only see a few feet ahead of you. It's intense and you'll need a light to navigate.
If you'd rather have the darker nights and not the changes to the weather there is a Lite version of this mod for PS4 as well.
