From the USDA:
The Natural Resources Conservation Service produces this weekly report using data and products from the National Water and Climate Center and other agencies. The report focuses on seasonal snowpack, precipitation, temperature, and drought conditions in the U.S.
As of November 8, almost 26% of the contiguous U.S. had snow on the ground, according to an analysis from NOAA’s National Operational Hydrologic Remote Sensing Center (NOHRSC).
This is the most expansive November 8 snow cover in the lower 48 in NOHRSC's 15-year analysis, topping the 21% coverage recorded on November 8, 2011.
The first week of November also produced one of the earliest snowfalls on record for the Seattle area. According to the National Weather Service, the snowfall measured in Seattle on November 4 was the third earliest snow event on record, and the earliest such event since 1975.
