These are almost like midwinter conditions.
On Saturday morning, most locations in Minnesota and North Dakota will see lows plummet into the single digits, which is record territory. Minneapolis is expected to fall to 5 degrees, which would mark its second-lowest April temperature on record.
The Arctic air will moderate as it heads south and east. But it is still expected to be cold enough to support rare April snow in the Mid-Atlantic and Northeast on Saturday, from Washington to Boston, where the temperature will be 10 to 30 degrees below normal (depending on location and time of day).
By Sunday morning, half the nation is predicted to have freezing low temperatures, including areas as far south as Oklahoma, Arkansas and Tennessee.
As cold as it is expected to be over the eastern United States over the next five days, temperatures across the remainder of the northern hemisphere are forecast to be generally warmer than normal. Temperatures in the Arctic are forecast to be about 30 degrees above normal, offsetting the cold in eastern North America.
In other words, this pocket of cold in no way refutes or invalidates the planet’s long-term warming trend.
