Chicago has been having a particularly weather spell, with 18-19 inches of snow last week (and additional 1 or 2 inches every couple of days). The temps have been in the teens (F.) since the end of last week, and will continue to be this week and next. When this happens it always makes me think of historians of the Russian campaign who downplay the effect of weather. Even today, with central heating and cars with heated seats (if the cars will start, not a given), there's a psychological effect (not to mention physiological effect) of the extended cold. Some how I get the suspicion those who claim "it wasn't that cold", live in more temperate climates.
