I think the title is self explanatory. I'd just like to go into a weekend without having the conditions pre-determined
i used to pine for this feature. Now i use this http://isiforums.net/f/showthread.php/11398-rFactor2-Weather-Tool can set up like in pcars where you set a historical date or date of your choosing. Easy to set up too. I like th fact you can set up less segments of weather, so instead of 5 weather changes you can set 3, so for smaller races it becomes more believable.. You can also hide the results so its a surprise when you race
Also uses a realtime weather server which gives you changing weather in realtime from the track location.
