Temperatures in the 60s, and possibly the 70s, in January? Who can complain? And the warm will stick around for a few days, owing to a high-pressure system that’s forcing storms to the north and west of Colorado, according to 9News. Denver could break a record. The highest temperature ever recorded on January 21 was 70 degrees in 1950. That’s about 30 degrees above normal.

Still, you’ve got to wonder if something is going haywire. Last month around this time, Denver was reporting record lows, including minus-19. But keep a shovel handy. The temperature could drop by more than 20 degrees by Friday, when there’s a 30 percent chance of snow in the afternoon, according to the Rocky Mountain News.
