Warning:
These predictions are not official. You should still complete all homework assignments, study for any tests/quizzes, and prepare to wake up for school on time unless the county states differently. These are only predictions.
One Pencil
Really good chance you will be in school on time. Do not count on a delay or closing.
Two Pencils
There is a 50% chance of a delay, but I would expect a full day of school.
Three Pencils
50% chance you'll have the whole day off, and very good chance at a delay.
Four Pencils
75% chance you'll be out of school tomorrow, but fairly certain there will at least be a delay.
Five Pencils
It's almost certainly safe to stay up late, because there will probably be no school tomorrow.
