November Comes in as Tenth Coldest in South Dakota’s History

We all knew the month of November was cold, but it goes down in the record books as the 10th coldest all time for the state of South Dakota. It was the coldest November since 2000, which stands seventh all time.

While South Dakota was founded on November 2, 1889, monthly weather records only go back to 1895 (so there are 6 years of the state history that are not included in this survey). The previous 10 November’s all finished above average and three of them rank in the top 30 of all-time warmest. That was not the case this year, as the state average temperature for the month was 25.7°F, which is 6.0° cooler than the average of 31.7°.

While November was the 10th coldest for South Dakota, it was the 16th coldest on record for the contiguous United States. According to the National Climatic Data Center (NCDC), during November, the average contiguous U.S. temperature was 39.3°F, which is 2.4°F below the 20th century average. This ranked as the 16th coldest November during the 1895-2014 time span, and was the coldest November since 2000.

A massive ridge/trough pattern set up over the United States during November, with the ridge over the West Coast and a massive trough over the eastern two thirds of the U.S. This led to very cold arctic air spilling south from the north and led to 18 states recording a top 10 all-time coldest November. Both Mississippi and Alabama had their second-coldest November of all time. On the contrary, due to the massive ridge out west, California had its ninth warmest November on record.

Many would argue that this year has been cold overall and the numbers would agree as well. According to the NCDC, from January through November, South Dakota is having its 25th coldest year to date. 12 different states are having their top 10 coldest years on record, while California and Arizona are having their warmest year all time.

The outlook for December is much warmer as the Climate Prediction Center is expecting nearly 80% of the United States to finish warmer than average.

Enjoy the warmer weather, we deserve it! (However, I am still rooting for a White Christmas!)
