As winter weather settles in, the National Weather Service (NWS) is reminding residents how important accurate snowfall measurements are—not only for meteorologists, but also for local communities, emergency managers, and media outlets that depend on reliable data.
To help everyone report consistent and meaningful snowfall totals, the NWS has outlined six simple steps for proper snow measurement.
1. Gather the Right Supplies
Before the flakes begin to fly, make sure you have the basic tools: a ruler or yardstick, a 24” x 24” whiteboard, and a small flag or marker.
2. Choose a Good Location
Snow should be measured in an open area away from tall objects like buildings or trees, but still sheltered enough to minimize interference from strong winds.
3. Set Up Early
Place your measurement board outside before snowfall begins. Mark the spot with a flag so you can easily find the board, even in heavy snow.
4. Measure Accurately
Record your snowfall total to the nearest tenth of an inch. After each measurement, wipe the board clean to prevent compaction or buildup. The NWS recommends taking measurements at the same time each day.
5. Measure When the Snow Ends
As soon as the snow stops, take a final measurement. This helps avoid underreporting due to melting, drifting, or settling.
6. Report Your Totals
Once you have your measurement, send your report to the National Weather Service through weather.gov or their social media channels.
With winter weather systems approaching throughout the season, the NWS encourages residents to take part in community reporting efforts.
Every measurement—big or small—helps improve forecasting and strengthens local weather awareness.
