Champaign-Urbana Climate Plots

Here are time series plots of annual temperature, precipitation, and snowfall for Champaign-Urbana, Illinois.

Because each snowfall season begins in one calendar year and ends in the next, the snowfall totals are plotted for the second year. For example, the 2007-2008 snowfall season is plotted as "2008". The typical snowfall season runs from November to March but measurable amounts have been reported as early as October and as late as May. To account for the wide variation, the annual snowfall was computed from July of the first year to June of the second year.
