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

Some of the first frost flowers of the fall season have emerged in Missouri, state wildlife officials said.. The delicate and short-lived flowers were spotted at Chesapeake Fish Hatchery, near ...
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 ...
A winter storm watch for Wednesday and Thursday has already been posted across much of northern Kansas and Missouri. Snowfall across the I-70 corridor could exceed 5 inches, and Kansas City could ...
