If you do NOT see Conditional Weather then you need to:
Exit from Skin Setting to Main Menu
Select WEATHER from the Main Menu Bar
Click in upper left corner of the screen or use the LEFT Arrow key to open the Weather Options Side Blade Menu
Select BACKGROUND
At this point you may/may not be prompted to install the background loader addon. If you ARE install it.
Once installed return to the Weather Options and Select BACKGROUND again and you should be presented with a list of what you presently have installed. If "Default" is the only one listed Select "Get More". Now scroll down to Weather Fanart and select the desired package and install it. Do the SAME THING for Weather ICONS while you're in here. Once complete return to the Weather Options, select BACKGROUND and you'll see the set you just installed listed. Select it. Do the same for ICONS.
Now return to skin settings and you should be able to see CONDITIONAL WEATHER in the list.
NOTE: I may not be 100% correct in these instructions as I am doing this from memory, keep in mind I'm 66 and I tend to forget some complicated things....but I still remember to kiss my wife every morning when she wakes
