How to Accurately Measure Snowfall: A Step-by-Step Guide

Accurate snowfall measurements are vital for weather forecasting, climate studies, and public safety. By following these straightforward steps, you can contribute valuable data to meteorological efforts.

1. Gather Necessary Tools

To measure snowfall effectively, you'll need:

• Snowboard: A flat, white surface (approximately 24" x 24") to place on the ground, ensuring uniform snow accumulation. (weather.gov)

• Yardstick or Ruler: A measuring stick marked in tenths of an inch for precise measurements.

• Marker: A flag or stake to identify the snowboard's location.

2. Select an Appropriate Location

Choose an open area away from buildings, trees, and other obstructions to minimize wind effects and ensure accurate readings. Avoid areas with snowdrifts or sheltered spots, as they can lead to misleading measurements. (weather.gov)

3. Set Up the Snowboard

Before snowfall begins:

• Place the snowboard on the ground in your chosen location.

• Mark its position with a flag or stake to easily locate it after the snow accumulates.

4. Measure Snowfall

After the snow has stopped falling:

• Clear any snow from the snowboard to ensure an accurate measurement.

• Place the snowboard back on the ground.

• Insert the yardstick vertically into the snow until it reaches the snowboard.

• Record the measurement to the nearest tenth of an inch.

• Clear the snowboard again to prepare for the next measurement.

5. Report Your Findings

Sharing your measurements contributes to broader weather data collection:

• If you're a trained storm spotter, call the designated number provided during your training.

• Alternatively, submit your report online or via social media platforms like Facebook or Twitter.

6. Additional Tips

• Avoid measuring snow on grassy areas, as the grass can distort the measurement.

• If using a flat surface like a picnic table, ensure it's in an open area away from obstructions.

• For consistent data, measure at the same time each day during a snowfall event.

By following these steps, you can provide accurate snowfall measurements that are invaluable for weather analysis and forecasting.
