A plains winter is not measured by the thermometer alone. On the coldest mornings, when the temperature has already plunged far below zero, it is the wind that finishes the job — stripping the warmth from any exposed skin and driving the wind chill to figures that can freeze flesh in minutes. The plains dweller learns to read the chill, not just the temperature, before stepping out the door.

When the Air Itself Bites

The physics is simple and merciless: moving air carries heat away from the body far faster than still air, so a modest cold in a stiff wind can be as dangerous as a far deeper cold in calm. On the worst mornings, schools close, block heaters hum in every parking lot, and the sensible resolve to keep their errands few and their skin covered.

From the almanac's reckoning:

• Wind carries body heat away far faster than still air.
• Wind chill can freeze exposed skin within minutes on the worst mornings.
• Block heaters and layered clothing are winter necessities.

It is a cold that commands respect and rewards preparation — the layered clothing, the emergency kit in the car, the habit of telling someone your route. The almanac counts the wind chill among the plains' sternest teachers, and counsels the newcomer to heed it well.
