Date of the first snowfall (any amount) at Fairbanks since 1915.
Climate observations have been made in town and at the Airport since the autumn of 1904, and in that time Fairbanksians have never had to wait until October 20 for the first flakes of snow. Not until this year that is. Rain changed to snow during the morning of October 20th, and before ending produced a slushy 0.1" (0.3cm) of snow, which then quickly melted. This is more than a week later than the previous latest first snow and nearly a month later than the average date for the first snow. Interestingly though, there is no trend toward later first snows at Fairbanks.
