A major storm that lashed parts of California with heavy snow and flooding rains over the Easter weekend is set to march from west to east across the U.S., sparking a multi-day severe weather outbreak this week. The NOHRSC measures snow water equivalent and soil moisture using gamma radiation remote sensing. This unique observing system includes two low-flying aircraft to conduct surveys in 31 states, including Alaska, as well as in 8 Canadian provinces. Four NOAA Corps officers pilot the aircraft and operate the remote sensing systems. The National Gridded Snowfall Analysis estimates snowfall in the recent past by gathering several operational data sets into a unified analysis. Snowfall observations are provided by numerous observing networks, including ASOS, COOP, CoCoRaHS, FAA, NWS spotters, and others. The 24, 48, and 72 hour accumulations can also be browsed on an Daily maps, charts, and animations show the extent of snow and ice over the contiguous United States, Alaska, or the whole Northern Hemisphere.
