[Groundhog Day] What caused Phil's time loop?

And for that matter, why ended it?
gpt
Punxsutawney Phil controls the time loop. The Seer of Seers and Prognosticator of Prognosticators was deeply offended when Connors called him a "large squirrel predicting the weather." Phil isn't a squirrel and he isn't predicting shit. He's a motherfucking *groundhog* and he *decides* when the seasons change. 

To punish Connors for his hubris, Punxsutawney Phil summoned a freak storm to trap him in his domain, then looped time until Connors learned his lesson.

Remember, it's not until Phil Connors delivers his sincere monologue on the beauty of Groundhog Day that his curse is lifted.
