What does Liesel describe the weather like?

From the text:

“Could you go up and tell me how the weather looks?”
Naturally, Liesel hurried up the stairs. She stood a few feet from the spit-stained door and turned on the spot, observing the sky.
When she returned to the basement, she told him.
“The sky is blue today, Max, and there is a big long cloud, and it’s stretched out, like a rope. At the end of it, the sun is like a yellow hole. . . .”
Max, at that moment, knew that only a child could have given him a weather report like that.
