Walt Kelly (1913-1973), creator of the comic strip Pogo, once remarked, “What’s good about March? Well, for one thing, it keeps February and April apart.”
Kelly understood that March, more than any other month, can manifest the temperature characteristics of both winter and summer. This year, Chicago’s March is off to a decidedly wintry start, but big changes are on the way. Daytime highs, six degrees below normal today, will climb to a rainy eight degrees above normal by Sunday.
Meteorological spring begins today
Today marks the start of meteorological spring, the three-month period from March 1 through May 31.
For meteorologists, a season is considered to be a division of the year according to some regularly recurrent weather phenomena. In the mid-latitudes, seasons are based upon the annual cycle of heat and cold; in the tropics (which lack significant temperature fluctuations through the year), seasons are often described in terms of the annual cycle of rain.
