Wyoming Snow Totals

How snow is measured

• Snowfall is new snow, measured on a flat white snowboard. Observers following NWS rules clear the board every 6 hours and add the readings into a storm total.
• Snow depth is all the snow on the ground. It is usually less than the snowfall because snow settles and melts.
• Partial totals: reports sent while snow is still falling are often marked in the remark ("so far", "in the last 24 hours"). Check the time.
• Warning amounts differ by NWS office: in much of the North a winter storm warning needs about 6 inches in 12 hours; in the South far less.

Before you head out

• Check winter storm warnings and your state's road conditions (511).
• Keep generators and grills outside, away from doors and windows: carbon monoxide kills in snowed-in homes.
• Clear snow from car exhaust pipes before running the engine.
• Official advice: NWS winter safety · Ready.gov winter weather.

What this page shows, and what it misses

Snowfall amounts in National Weather Service Local Storm Reports from the last 72 hours, refreshed every 30 minutes. These are spotter and observer reports — trained spotters, co-op and CoCoRaHS observers, automated stations, the public — passed on by NWS offices as received, not a measured grid. Where one place reported more than once, the largest report is shown. Places with snow but no report are missing, and totals can be revised. Alaska and Hawaii are included when their offices report.
