Whenever a winter storm arrives, one of the most exhilarating questions is: Is tomorrow a snow day? Although snow day calculators create an easy way to estimate the snow day's chances, have you ever thought about how those predictions are made? Let's take a brief overview of the main factors affecting snow day predictions explained in basic terms.
One of the easier considerations is how much snow is predicted. We have a solid chance of having a snow day if we expect heavy snow (generally more than 3-5 inches overnight). Schools often close when roads become unsafe for buses or cars during day time hours, or sidewalks become too slippery to walk on. Even if the snowfall doesn't meet heavy snow totals, if things are wet and icy we may still have delays or half days.
It's not solely about the snow—school closures occur when it is extremely cold outside as well. When temperatures dip below 0°F (or -18°C), children walking to the bus could face frostbite; and that's not counting the wind chill, which makes the air feel even colder than indicated on the thermometer. Even when there is not a major snowstorm occurring, schools will still call snow days when the forecast indicates a serious cold snap.
Strong winds may also spawn blizzards or whiteout schedule conditions, which reduces visibility to a point where driving is dangerous. Even after lingering snow is gone from roads, blowing snow and drifting can continue to create an unsafe travel next morning. School districts and local officials may provide an extended snow day or "day-after-snow day" for the school district to have adequate time to remove heavy snow.
Icy or unplowed roadways can still be a problem after the storm has ended. School buses need a cleared or salted roadway to do so safely and if the city workers are not able to clear the streets, school may be delayed or canceled for the day. In suburban or rural areas, the closures may be greater because the counties or municipalities may take longer to clear the roadways, as there are fewer residents in those particular regions.
When discussing the amount of snowfall, the timing may be just as impactful. For example, if heavy snow begins to fall overnight or very early in the morning, it will immediately affect morning travel. However, if heavy snow begins to fall in late afternoon, schools may be open for the full day, but the school may dismiss your child early.
• Snow at night = higher chance of a snow day
• Snow after school hours = lower chance
Snow day predictions also depend on where you live. For example: A few inches of snow might shut down schools in Texas or North Carolina (where snow is rare). The same amount wouldn't affect schools in Minnesota or New York, where snow removal is faster and more common.
Snow day calculators rely on precise weather forecasts and if those forecasts change for example, the prediction will also change if snow turns to rain. This is why snow day calculators use live data from weather services and update regularly, sometimes every couple hours. In order to gain the best information, you should never trust a forecast one day and not check it the night before or the morning of.
Even if two districts are in the same town, they may have different decisions about closing. Some districts are more conservative and close early and others wait until conditions deteriorate. Typically, superintendents will confer with local law enforcement, local road crews and meteorologists prior to making an official decision.
