Will the polar vortex make a comeback in the US in February?

02.02.2020

The polar vortex has been absent from the United States for most of winter thus far, which led to a very warm January, Accuweather reports.

The Eastern Seaboard through the central and southern Plains recorded temperatures that averaged well above normal by the end of the month. The average temperature was also above normal for the interior portions of the West.

February is forecast to start off with more abnormal warmth across the Plains and East, but some changes are expected as we move through the second month of the year.

The colder air expected to slice into the Central states during the first part of next week may be a sign of even more brutal Arctic air that could take root later in the month.

"We are anticipating that a strong push of Arctic air will take place into the U.S. during the second and third week of February in response to a displacement or weakening of the polar vortex during the first week of February," AccuWeather Lead Long-Range Meteorologist Paul Pastelok said.
