2024年10月3日 · For the I-95 Stretch from NYC to DC, you will be hard pressed to find snowfall before Thanksgiving. And although New England usually receives its first accumulation of snow before the end of November, most of the Northeast has to wait until mid-December or longer for the real accumulation.

2024年10月16日 · S nowfall has coated parts of the mountain West and higher elevations in the East already this fall, but for some major U.S. cities, the record earliest snow has happened even earlier on the...

2018年12月4日 · Dec. 5, 2002 - One year after record warmth occurred on this date (high of 70°) six inches of snow fell, the biggest snow so early in the season since 1938. Dec. 25, 2002 - A sloppy winter storm produced the most precipitation ever measured on Christmas Day (1.30") and the most snow (five inches) since 1909 when seven inches fell (the most ...

2017年9月30日 · Any given season can produce the season's first snowfall either very early or very late, depending on the weather pattern at the time. The tables below list average first …

2024年10月1日 · Here's how meteorologists define the first accumulating snow: Snow totaling 0.1 inches or more is what qualifies as accumulating snow, also known as measurable snow. It can't just be...

The Snow Cover Extent Climate Data Record extends from the late 1960s to present. Historical analyses based on visual inspection have been digitized and combined with modern multi-spectral remote sensing to produce a seamless record on a hemispheric scale. The data are available at weekly and monthly resolutions in a variety of formats.

Early season snow observations show promise in predicting peak snow water equivalent in locations where large-scale ocean-atmosphere patterns similarly influence fall and winter conditions, and in northern maritime locations where winter temperatures are warm enough that rain on snow and midwinter melt occur.

This data set consists of daily 25 km snow cover extent for the Northern Hemisphere from 1 January 1999 through 31 December 2012. Snow cover extent is represented in four different variables derived from the following three source products: • The Interactive Multisensor Snow and Ice Mapping System • MODIS Cloud Gap Filled Snow Cover

2025年1月22日 · SnowEx Campaign data is publicly available through the NASA DAAC at the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado. Data are available to anyone at no cost, as is the case with all NASA data.

This data set provides maps of snow cover and sea ice for the Northern Hemisphere from February 1997 to the present from the United States National Ice Center (USNIC). USNIC analysts produce these using the Interactive Multisensor Snow and Ice Mapping System (IMS).
