Christmas this year for many parts of the US is going to see some extremely unexpected weather. According to weather.com Christmas specifically is going to see "unseasonably warm air and daytime highs...running as much as 25 to even 30 degrees above average" in parts of the states.
This is not out of the blue, however, because according to AccuWeather, "record warmth has been a common occurrence around the country this December." The article continued, stating that it expects this whether to continue into Christmas and potentially beyond. In particular, the past weekend was extremely warm in this part of the US, with extremely old and long-lasting records having been broken.
AccuWeather pinpoints the reason for this unexpected weather on both a high-pressure system that will take shape over the Southeast and a storm that is expected to spin over the Rockies. The article provided further reasoning, saying that "very warm air originating from Mexico will be pulled northward into the south-central U.S."
