poudre day 
See 1909 quote.
- 1873 (1904) The sun, which on one of these "poudre" days in the North seems to exert as much influence upon the war of cold and storm as some good bishop in the Middle Ages was wont to exercise over the belligerents at Cressy or Poictiers . . . muffled himself up in the nearest cloud and went fast asleep until the fight was over.
- 1909 A day like this is called a poudre day; and woe to the man who tempts it unthinkingly, because the light makes the delicate mist of frost shine like silver. For that powder bites the skin white in short order, and sometimes reckless men lose ears, or noses, or hands under its sharp caress.
- 1951 It was a real "poudre" day. Only a few inches of dry, fine snow lay on the prairies, just enough to provide easy sledding for the dogs. . . .
