Tuesday morning, America 'as a whole' awoke to the coldest it has been in November since 1976 -- 38 years ago. The Lower-48 or CONUS spatially average temperature plummeted overnight to only 19.4°F typical of mid-winter not November 18th! Data
An astounding 226-million Americans will experience at or below freezing temperatures (32°F) on Tuesday as well -- if you venture outdoors.
More than 85% of the surface area of the Lower-48 reached or fell below freezing Tuesday morning. All 50-states saw at or below freezing temperatures on Tuesday.
Record lows from Idaho to Nebraska and Iowa south to Texas and east through the Great Lakes, the eastern 2/3 of the US will shatter decades-long and in some cases, century-long records. Temperatures east of the Rockies will be 20-40°F below climate normals.
Compared to normal, temperatures over the past several days have dropped off a cliff -- to 10°C below climate normal -- more anomalous than even during the polarvortex of early January. Anomaly Chart. November is shaping up to be a colder-than-normal month by a lot.
