The maximum frost depth observed in the contiguous United States ranges from 0 to 8 feet (2.4 m). [1] Below that depth, the temperature varies, but is always above 0 °C (32 °F). Alternatively, in Arctic and Antarctic locations the freezing depth is so deep that it becomes year-round permafrost , and the term " thaw depth " is used instead.
In astronomy or planetary science, the frost line, also known as the snow line or ice line, is the minimum distance from the central protostar of a solar nebula where the temperature is low enough for volatile compounds such as water, ammonia, methane, carbon dioxide and carbon monoxide to condense into solid grains, which will allow their accretion into planetesimals.
Permafrost temperature profile. Permafrost occupies the middle zone, with the active layer above it, while geothermal activity keeps the lowest layer above freezing. The vertical 0 °C or 32 °F line denotes the average annual temperature that is crucial for the upper and lower limit of the permafrost zone, while the red lines represent seasonal temperature changes and seasonal temperature ...

More than 17 million people were cautioned Saturday under National Weather Service winter alerts, including 3.6 million under lake-effect snow warnings, 4.5 million under freeze warnings, 8.5 ...
Cover outside water spigots. Before the temperature drops below 32 degrees, outdoor water spigots attached to homes should be opened to allow to drain water out, closed and then covered.
Map showing the snowbelts around the Great Lakes of North America with 150 cm (60 in) accumulations or more during winter. The Snowbelt, Snow Belt, Frostbelt, or Frost Belt [1] is the region near the Great Lakes in North America where heavy snowfall in the form of lake-effect snow is particularly common. [2]
