Warm and dry winters are very commonly seen during La Niña. The jet stream sets up a pattern favorable for above normal temperatures with below normal precipitation. But the truth is, winter seasons are not as cold as they were fifty years ago. On average, winter temperatures are about 3.5 degrees warmer than in 1970, according to Climate Central.
In addition, the number of days spent with above normal temperatures has also climbed over the past fifty years.
It is important to note, even in this pattern, there can still be cold winters or extreme cold spells. Extreme cold happens when polar air sinks south into Texas. One example of that was the February 2021 winter wave in Texas. While we are experiencing an overall warmer winter, we still need to be prepared for the eventual cold spells.
