Some show a light dusting, others show feet of snow, and plenty of them go viral days before anyone actually knows what’s going to happen. I’m WeatherBug meteorologist Cate Kerrigan, and few things make me cringe more than a screenshot of a single model run claiming some town is getting 30+ inches of snow, a full week before the storm. Here’s where those maps come from, why they change so much, and how to tell what’s worth your attention. ## **Where Snowfall Maps Come From** Most of the snowfall maps you see online are screenshots straight from weather models. Weather models are computer simulations that take a snapshot of the current atmosphere and project it forward in time, and there are several of them that each handle the atmosphere a little differently. The catch is that the starting snapshot is never perfect. Tiny errors early in the simulation can snowball into big differences days later, which is why one run might show a historic blizzard and the next run shows almost nothing. Neither run is “lying”, but neither is perfect. They’re just different possible outcomes. ## **How to Spot Snowfall Map Hype** ### **1\.** Check how far out the storm is. Confidence drops fast the further out you go. Anything beyond 3 days is lower confidence, and anything beyond 5 days is a pretty blind guess. A storm that looks like a record-breaker on day 7 can shrink, shift, or disappear completely by day 3. ### 2\. Check what the map is actually counting as snow. Look near the top of the map for a ratio like “10:1.” That means the map assumes every inch of liquid becomes 10 inches of snow. In reality, that ratio can range from about 5:1 for wet, slushy snow to 25:1 for very cold, fluffy powder. Some maps also count sleet or rain as snow, which can inflate totals even more. Some maps, especially ones labeled with “Kuchera”, account for a fluctuating liquid-to-snow ratio but still rely on too many atmospheric variables to be perfect. ### 3\. Remember how small changes make a big difference. Snow forecasts are sensitive. A storm track that shifts just 50 miles, or a temperature that’s off by a degree or two, can turn a foot of snow into a cold rain. That’s why snowfall totals are much harder to pin down than a general “storm is coming” forecast. ### 4\. Look for agreement. If one map shows two feet of snow but the National Weather Service is forecasting a fraction of that, the big number is probably the outlier. Professional forecasters compare multiple models and multiple runs to find what they agree on, and that’s much more reliable than any single map. ### 5\. Ask why it’s being posted. A map showing 40 inches of snow is going to get far more shares than one showing an inch or two. Some pages intentionally post the most extreme model run because it drives engagement, not because it’s the most likely outcome. ### 6\. Check the source, the model, and the date. If a map doesn’t say which model it came from or when it was made, it’s hard to know whether it’s still relevant. Models update several times a day, so an old screenshot can be out of date within hours. **Wondering if snow will hit during your commute? Check your local hourly forecast in the [WeatherBug app](https://apps.apple.com/us/app/weatherbug-weather-forecast/id281940292) before you head out. Snow timing can shift as the storm gets closer.** ## **Where to Get a Reliable Snow Forecast** When snow could affect your plans, start with your local forecast with WeatherBug. You can also check out your National Weather Service office or a degreed meteorologist you trust. They look at the full picture, including multiple models, recent trends, and local factors, instead of a single run, and they update the forecast as the storm gets closer. If you want to look at model maps yourself, that’s totally fine. Just treat them as one piece of the puzzle and pay the most attention once the storm is within a few days. ## **Frequently Asked Questions** ### **Are snowfall maps on social media accurate?** It depends on the source and how far out the storm is. Maps shown more than 3 days ahead are lower confidence, and beyond 5 days they’re a pretty blind guess. ### **Why do snowfall forecasts change so much?** Weather models start with an imperfect snapshot of the atmosphere, and tiny errors can grow into big differences over time. Small shifts in a storm’s track or temperature can also change snow totals a lot. ### **What does 10:1 mean on a snowfall map?** It’s the snow ratio the map assumes, meaning each inch of liquid becomes 10 inches of snow. Real ratios can range from about 5:1 for wet snow to 25:1 for very cold powder. ### **Why do pages post extreme snowfall maps?** Dramatic maps get more likes and shares. Some pages choose the most extreme model run to attract attention, even if it’s not the most likely outcome. A snowfall map from one model is just one possible outcome, not THE forecast. Check how far out the storm is, look at what the map is counting, compare it with the National Weather Service forecast, and think twice before you share that 40-inch map.
