The rain should finish by late evening or early Thursday morning, according to the National Weather Service. There’s a 30 percent chance of lingering thunderstorms Thursday, but most of the weather should have blown through by the time Thursday classes start.

By 8:30 Wednesday night, Norman had received 1.87 inches of rain, and the final total after the rest of the system has moved through should be around 3-4 inches, according to the National Weather Service.
