“The trouble with the last snowfall of the season is that you can’t be sure”

Around the end of March or the beginning of April, many people announce “the last snowfall/snowstorm of the season”—and then it often snows again a few days later. “The trouble with the last snowfall of the season is that you can’t be sure” is a seasonal saying that has been printed on many images.
 
“Why is the season’s last snowstorm always followed by another one?” was written by American newspaper columnist Doug Larson (1926-2017) in his column in the Green Bay (WI) Press-Gazette on April 1, 1972. “The last snowfall of the season occurs several times in March and April” was written by Larson in the Green Bay (WI) Press-Gazette on March 4, 1982.
 
“The trouble with the season’s last snowfall is that you can never be sure it is” was written by Doug Larson in the Green Bay (WI) Press-Gazette on March 20, 1993. “The trouble with the season’s last snowfall is that you can’t be sure” was written by Larson in the Green Bay (WI) Press Gazette on March 3, 1994.

Doug Larson (February 10, 1926 to April 1, 2017) was a columnist and editor for the Door County Advocate (1953–1964) and wrote a daily column, “Doug’s Dugout,” for the Green Bay Press-Gazette (1964–1988), both Wisconsin-based newspapers. The column was originally syndicated through United Media under the title “Senator Soaper Says”; Larson took over authorship in 1980. Previously, it had been written by Bill Vaughn of the Kansas City Star. Larson was born in Sturgeon Bay, Wisconsin.
