However, it also doesn’t hurt if the forecast says it’ll start to snow heavily during school hours, because your school administrators will not want to deal with the mess of trying to get everyone safely home in the middle of a snowstorm. Sometimes, you may also get an early dismissal, which is better than nothing. You should also look for changes in the forecast. If it drastically changes and it looks like you’ll be getting more snow than expected, then you’re in a good place! Consider how many inches of snow you will get. If it will be snowing all day but there will only be 1–2 inches (2. 5–5. 1 cm) of precipitation, then you may still have to go to school. Check if a winter weather advisory is in effect during school hours. Winter weather advisories are issued by the government when dangerous weather is expected. If the government considers the upcoming weather to be dangerous, chances are your school will too. Consider the possibility of ice. If rain is expected alongside freezing temperatures, you are likely to get some ice. This is good news because if the ice freezes onto the roads, transportation may not be as safe and therefore school is more likely to get cancelled.

Some people also believe that if the bus drivers think that there will be a snow day tomorrow, then it may be more likely that school will be cancelled. If your parents know some teachers at your school, or if one of your friends happens to have teachers in the school as parents, then he or she may have some insight into whether or not you’ll have a snow day earlier than the general public. Also, some superintendents even communicate snow days over Twitter. Though you’ll be called soon after the decision is made, you can have a leg up by checking out your administrator’s Twitter page, if he or she has one.

If you are on a mobile device, you can also search the app store for “snow day” to see all the snow day prediction tools available. Make sure any snow day calculators you download from the app store are relevant to your country. Most of these calculators only predict closures in the USA and Canada, so they might not be an option if you live elsewhere.

And hey, if you don’t end up getting a snow day, it’s not the end of the world. Public schools have a certain allotment of snow days for each year, and if you get too many snow days, you may have to come to school during holidays, or even to go to school late into the summer!
