If you remember NLA natural lighting and atmosphere for enb from Skyrim Le
this mod is probably what you need
this is not only a weather mod, it's a  ENB resourse for all modders 
and is also a simple ENB preset that would work easy on potato PC
givin the possibility to have a great results with no fps loss
as for NLA this is a starter pack for the next generation Enbs
The Weather mod is based on my Solstitium weathers and seasons
and add 8 new custom weathers over the 90 possible of vanilla plus the Season functionality
It contains also a beginner Enb preset, this preset is basic and not Fps eater
so it would run also on potato pc giving a great look to the game
It adds the weathers.ini function resource, this means that every weather can be tweaked at your own taste
in NRL case all weathers have differents and uniques dusks and dawns and also sky lighting plus different clouds
You can change any effect and any weather situation can be unique 
it's an open resourse so this means you can use, add and tweak my ini into your ENBS as you like
The Season functionality will activate after you go to sleep for 8 hours
you don't have necessary to use my weather mod included
you can use the enbseries content to tweak and custom your weather mod in use
( only vanilla FORMID, custom weathers need to be added in the weather list and INI to be created, see video)
( Just remember to credit me )


video Tutorial to how to add custom weathers and tweak

To tweak everysingle weather.ini
open the gui menu ingame (shift+Enter)
enable multiple weather windows
and you will be able to tweak weathers recalling them
If you want to tweaks other effects
remember to enable or disable from the 
main Enbseries.ini
"ignore weather system"

Simple explanation how to use NRL

- you can use NRL all package, this means you can use its enb and its settings
( u can modify its setting to your own taste) and only with its weather mod
or
- you can use your ENB ( for example Rudy ) in combination with NRL weather mod,
you have to merge the ENBSERIES folder and tweak the inis to match 
the enb base, the enb you use have to be updated to latest binary 
iNSTALL first NRL then your ENB
or
- you can use your enb and your weather mod and just merge my ENBSERIES folder (optional file resourse)
and tweak the inis to your taste to match the 
enb base and the weather mod, but you will ba able only to tweak the vanilla weathers,
if your weather mod use custom weather you have to add them to 
the weatherlist and create eventually their own ini ( see video )
Enb has to be updated to latest binary

Installation:

TO make this work you need to Download this first ENB Helper Se
