Go to the app store and download the SixFlags App. It'll tell you real time which rides are open an which ones are closed or just temporarily closed.
I went with my friends and it began to rain. They closed all the rides. (Even the tea cups which are under a roof)
High winds and lightning shut down some rides but most stay open and lines are normally very short
If it starts to rain throughout the day on and off the park will be open but some of the rides will definitely shut down
Not all the rides will be open
