The National Snow and Ice Data Center (NSIDC) is a United States information and referral center in support of polar and cryospheric research.NSIDC archives and distributes digital and analog snow and ice data and also maintains information about snow cover, avalanches, glaciers, ice sheets, freshwater ice, sea ice, ground ice, permafrost, atmospheric ice, paleoglaciology, and ice cores.
"The level and extensiveness of the frigid air may be tough to match the rest of the winter," forecasters warned. Heavy snow, dangerously low temperatures put more than 70M under winter storm warnings
The Vashon Glaciation, Vashon Stadial or Vashon Stade is a local term for the most recent period of very cold climate in which during its peak, glaciers covered the entire Salish Sea as well as present day Seattle, Tacoma, Olympia and other surrounding areas in the western part of present-day Washington (state) of the United States of America.

Major winter storm to bring heavy snow and ice from Plains to mid-Atlantic as arctic cold temperatures will set in through mid-January. Kate Murphy. January 3, 2025 at 4:42 PM.
Summertime Arctic-wide sea ice extent simulated by the GFDL CM2.1 model for the historical period 1860 to 2000 and projected for the 21st century following the SRES A1B emissions scenario. Sea ice extent values are normalized (scaled) so that the average for years 1981 to 2000 is equal to 100%. Totally ice free summer conditions would equal 0%.
The season's most drastic drop in temperatures has now engulfed the central and eastern states with dangerous wind chills and the arctic air could even topple some record lows.
The Arctic ice pack is the sea ice cover of the Arctic Ocean and its vicinity. The Arctic ice pack undergoes a regular seasonal cycle in which ice melts in spring and summer, reaches a minimum around mid-September, then increases during fall and winter. Summer ice cover in the Arctic is about 50% of winter cover. [1]
The first true outbreak of Arctic air in the United States will accompany the first far-reaching heavy snowfall of the season from the northern Cascades to the northern Rockies and northern Plains ...
