Snow totals at ski resorts

NOAA's snowfall estimate for 495 ski areasin the contiguous US: the season so far and the latest 24 hours, each for one ~4 km grid cell at the resort's lowest mapped lift station. Not the resorts' own snow reports. A dash means no estimate, never zero.

Where these numbers come from

Snow that fell: NOAA National Snowfall Analysis
Published by NOAA’s National Operational Hydrologic Remote Sensing Center (NOHRSC) on a ~4 km grid of the contiguous US. It blends radar-based precipitation estimates, a snow-to-liquid ratio and reports from volunteer and cooperative observers. 24-hour totals end at 12:00 and 00:00 UTC and appear about two hours later; 72-hour and season totals are built from the daily 12:00 UTC analysis. NOAA re-runs each analysis for about five days as late reports arrive, so a total can change.
Snow that’s coming: National Weather Service
The NWS gridpoint forecast for the spot: snowfall, ice, temperature, chance of precipitation and wind in 6-hour steps for the next 72 hours.
What it cannot tell you
A grid estimate is not a ruler in your yard. Snow drifts, settles and melts; totals can change a lot within a few miles; and narrow lake-effect bands can fall between grid cells. Treat these numbers as a good estimate for your area, not a measurement at your door.
