General Weather Forecast Summary for January 2021

December 21, 2020

Chill out! Our January 2021 weather forecast is here. Let’s take a look at what sort of weather we can expect to start the year with.

January Weather

Overall, January 2021 is expected to bring colder-than-normal temperatures across most of the eastern and central United States, with higher-than-normal temperatures in most western areas. Quebec and Ontario will be colder than normal, on average, while most other Canadian locations will have above-normal temperatures in January. Most areas across the United States and Canada will have above or near-normal precipitation, with the Pacific Northwest being the chief exception

As for the rest of winter, we expect that temperatures across most of the United States and Canada will be above normal, with some particularly mild periods possible in February.

Holidays and Observances

Let’s spotlight a few special days this month:

  • As we welcome the new year on New Year’s Day (January 1)—with great hope for an improvement over 2020—most of the United States will have cold temperatures, with snowy periods from the Northeast across the Great Lakes, rain showers in Florida and the Deep South, and scattered showers in the West. Most of Canada will be on the cold side, although rain is likely in the Maritimes.
  • January 5 is National Bird Day. While cold temperatures in the Northeast and Pacific states may keep you close to the nest, temperatures will soar above normal elsewhere.
  • For January 18, Martin Luther King Jr. Day, most of the United States will have relatively mild temperatures, with the greatest exception being in the Northeast, where snow showers and very cold temperatures will prevail.

Weather and Climate Patterns

We are now in Solar Cycle 25, which is expected to bring very low solar activity. Although low levels of solar activity have historically been associated with cooler temperatures, on average, across Earth, we believe that recent warming trends will dominate in the eastern and northern parts of the United States in the coming winter, with below-normal average temperatures limited to the western portion of the nation. Temperatures will average above normal in most of Canada, except for Atlantic Canada and the Prairies, where below-normal temperatures are expected.
