Don't worry kid, it's more than you're going to get. It'll rain by tomorrow, and you'll be back at school. As much as it pains me, so will I.

Schools would be closed only if roads become either too thick, or too icy to drive on.

As little as 6 inches but where I live a foot is the Rule. I don't live in England though I live way north

If the roads are slick, or like 5 inches of snow. Sorry i dont know metric.

whenever it stops people driving
