Weather not changing

I've got players telling me that the weather isn't changing and that it's been raining a long time. Below is my config. Could we get some debug code showing when weather changes?

I am also getting the same messages from players. I was planning on making all weather 60 seconds this evening to form a better test/conclusion.

Weather switches just you have a very high chance of clear weather 65%

As you can see in my config I posted above, the chance is 65%. Does that need to be higher? 80%? 90%?

I changed the config on my test server so that sunny had a 90% chance but it didn't seem like it was sunny any more than before. I set the time to change the weather to 60 seconds so I could confirm that the weather was changing. By doing that I noticed that when the weather changed it was sudden with no transition, which is immersion breaking. Weather doesn't go from sunny to a storm. It begins to get cloudy, then light rain, leading up to heavy rain.

65 is too much (meaning that at 65% the weather will be "Clear") 

Smoothness when transitioning will be added later

Changed Fixed In to Next Version

I'm confused by your responses. First you said I have a high chance of clear weather with is set to 65% and then you told me it's too high... can you go into more detail about how the percentage chances work? If I want mostly clear with occasional rain, fog, etc. How should I set the percentages up?

I am having issues with the weather not changing as well. For example, I have Fog set at 1800 seconds (30 minutes) and it stays foggy well over 30 minutes. I let it go to an hour before I manually changed it for the players.

@BetterDeadThanZed If you need it to be mostly clear weather you can leave it that way, it's just that if you have clear weather now and next time you happen to have it, it will last (i.e. you can have the same weather in a row).
