Looking at station data through Dec 27th, there is a strong chance that Dec 2023, will exceed Dec 2021, as the warmest Dec on record for the Contiguous U.S. The last 4 days of the month must average about 3.1F above normal to finish in 1st place. No chance of dropping below 2nd. pic.twitter.com/MiQDX2c4Py

How does 2023 compare to the 1930s?
1930s was quite warm in the US, but remember the US is only 2 percent of global land surface.
Globally temps are warmer today.
Good explainer here from Jeff Berardelli, chief Meteorologist at WFLA in Tampa
