Does any one know if there is a way to set it so some times when a map loads, its rainy, or sunny, or any other forcast?

and is there a way to set different weathers for different modes, such as hunt, ctf, conquest?

You could try creating a second .wld file for your map and making sure your .lua (for each mode) references it. Using variable assignments and .lua's math.random function, you could work from there and make a random weather be loaded on each startup - but all that random stuff is presuming that you can load one map from different world files.
