At the tail end of the transition from autumn to winter, Thanksgiving weather is typically pretty chilly, but can range from almost warm to brutally cold. A typical Thanksgiving day though has highs in those mid 30s with a little sunshine.
Since 1872 though, we have seen a 50° high or warmer 11 times, with the most recent occurring in 2012 when we hit 60. 1914 and 1922 share the title of warmest Turkey Day with a high of 62.
On the flip side though, frigid temperatures are more common with subzero lows occurring 10 times, with the most recent in 2014. But sub-freezing highs are extremely common as nearly half of all years have been below 32 since records began 140 years ago.
Snow is also quite common by the end of November, occurring in 29 different years, which is roughly twice a decade on average. The most snow that ever fell on Thanksgiving Day was 5 inches back in 1970 with the latest at just over an inch in 2015. While measurable snow actually falls on Thanksgiving twice a decade on average, we wake up to snow on the ground a little more often as you can see in the map above… with about half of our Thanksgivings are snow covered in the metro. The deepest snow pack is a tie with 1921 and 1983, both with 10 inches on the ground by Turkey Day.
