Hi Kray
Here’s a triplea game that uses weather. Might give you some ideas

I thought this was hilarious. My friends decided to make a rule that combat decisions we only get 5 minutes and only 2 minutes for non-combat. They said it was because I took too long. I told them it was because the axis has so many units it takes a while. So I finally agreed and said I was the allies. So we started the game and my friend that made the rule was Germany and because of the time limit forgot to attack France. LOL.
Epic Fail.
I am justice!
A better solution would be 30 min for majors, and 15 for minors.
