Right now none of the 1,545 US cities we track has an inch of snow on the ground — the snow on the map is in the mountains. One map, the whole snow story: what fell (last 24, 48, 72 hours and the season), what is on the ground now, and what the National Weather Service expects in the next three days — switch with the bar at the bottom, or press ▶ to play it. Updated every hour from official NOAA data.

City snowfall averages, live alerts and the local 7-day snow forecast for 1,548 US cities.
It is the NOAA National Operational Hydrologic Remote Sensing Center (NOHRSC) SNODAS analysis: a 1-km snow model that is corrected every day with ground stations, airborne gamma surveys and satellite snow cover. It shows the snow on the ground as of 06:00 UTC each morning.
The map shows a 1 × 1 km average. Drifts, shade, plowed piles and elevation differences inside that square can easily double or halve what you measure in one spot.
Snowfall is how much new snow fell in a period (switch to “24 h” or “72 h”); snow depth is what is still on the ground after settling, melting and wind. A fresh 10″ snowfall often settles to 6–7″ of depth within a day.
Once a day: the NOHRSC analysis is published each morning and this page picks it up within the hour. The forecast and alert layers update every hour.
