50’s in December Common…A Ton of 50’s? Not So Much

Dec. 09, 2015: We jumped up into the 50’s today, and this may mark the first of five days in a row with the 50’s this week!

The 50’s aren’t uncommon for December.  In fact, over the last 30 years, we’ve averaged 2 days in the 50’s each December.


What is uncommon is the amount of 50° days. Every few years, we get a handful of the 50’s, rather than one or two days here and there. The last came in 2012, with 5 days in the 50’s.

Even more uncommon: this would be the latest stretch of 5 or more days of 50° weather on record for December, if it pans out.  According to the National Weather Service-Chicago, there hasn’t been a stretch of 5 days or more in January in the 50’s, so this could be the latest 5 day run for meteorological winter!
