“A green Thanksgiving means a white Christmas”

“A green Thanksgiving means a white Christmas” is a winter adage. If it doesn’t snow on Thanksgiving, it will snow on Christmas. If it does snow on Thanksgiving, it will not snow on Christmas. No statistics have tested the adage.
 
“The old tradition ‘Green Thanksgiving, White Christmas’” was cited in print in 1928—before Irving Berlin’s 1941 song “White Christmas” made that idea popular.
 
   
21 December 1928, The Daily Messenger (Canandaigua, NY), “Year’s Shortest Day Comes With Drop In Temperature,” pg. 1, col. 2:
Light snow which flurried through the air gave hopes of a white Christmas, although there are only three more days left. If the old tradition “Green Thanksgiving, White Christmas” and vice-versa holds any truth this year, Santa will not have to use his sleigh when he visits Canandaigua Christmas eve.

Depends where in the states you live. In St. Louis it snows every winter, and an old wives tale says that if it snows on thanksgiving, it will be a green christmas, but a green thanksgiving means a white christmas ^_^

But remember that old saying, “Green Thanksgiving means a White Christmas.” That would be just fine by me.
