Change weather condition in cities? (It's always windy)

[TwuTu]

Simple question: How do I change the weather condition in the cities?

I've noticed that it's always windy. That may come from the recent Santa Event on the official server. The windy weather was due to Santa flying above the cities.

How do I "remove" that?
