U.S. data: February was coldest in years
Arctic blast left Arkansans shivering
The Lower 48 states had their coldest February in more than 30 years, new data reveals, due largely to the winter storm that engulfed Texas, causing a deadly energy crisis.
The cold, which was associated with a deep southward dip in the jet stream that sent polar air plunging to the U.S. border with Mexico, knocked out power to millions in Texas, Louisiana and other states due to the inability of power equipment to withstand the cold.
According to data the National Oceanic and Atmospheric Administration released Monday, during the Feb. 11-16 period, more than 120 all-time low temperature records were broken across the central and southern U.S. Six states, Nebraska, Iowa, Kansas, Missouri, Oklahoma and Arkansas, registered one of their coldest 10 Februaries on record.
The month ranked as the 19th-coldest month of February since reliable instrument records began 127 years ago, the administration found. Despite the cold February, the months of meteorological winter, consisting of December through February, were in the warmest one-third of past winters, at 1.4 degrees above average.
The cold in the U.S., combined with unusually frigid air across much of Eurasia, resulted in global warmth less pronounced compared with recent Februaries, according to a separate report released by the Copernicus Climate Change Service, a program of the European Commission. Copernicus found that globally, February averaged about 0.46 degree above the 1981-2010 average and still 2.2 degrees above preindustrial levels, when averaged over the past 12 months.
The planet’s average temperature was cooler compared with other recent Februaries, but still well above average, in keeping with trends related to global warming. The relatively cool start to 2021 is a likely indication that the year won’t set another record for the warmest year, as 2016 and 2020 did.
Interestingly, while Siberia and other parts of Russia and Europe, along with the U.S., were unusually cold, the Arctic was unusually mild for the month, Copernicus scientists reported.
The new temperature data backs up previous findings showing that while the cold and winter storms in the middle of the U.S. were severe, they were not unprecedented. In fact, Texas had its 11th-coldest February on record, missing a spot on the top 10 list.
A number of locations dropped to their coldest readings since December 1989, including Houston, which fell to 13 degrees on the morning of Feb. 16. The only time on record that Houston Intercontinental Airport has been colder was during the 1989 cold episode, when a low of 7 degrees was observed.
Austin’s lowest temperature matched the mark set during 1989, with the mercury falling to 6 degrees during the height of the arctic blast. In 1949, the low fell to minus 5 near the city on Jan. 31 of that year.
In Dallas, temperatures during this year’s outbreak got down to minus 2, beating out the low of minus 1 set during the 1989 episode and narrowly missing the record of minus 3, set all the way back in 1930.
Oklahoma City came close to a record as well, making it down to minus 14 — the lowest reading there since 1899.
Omaha, tied with 1989 in terms of its coldest low ever observed at Eppley Field, which fell to minus 23 on the 16th. Records at Eppley date back to 1935.
A number of nearby locations recorded slightly lower temperatures during that time frame. The longevity of the cold was especially noteworthy, with some places on the Plains seeing subzero lows for 10 days or more.
Minneapolis, for example, had 12 consecutive nights with lows below zero, a streak that featured nine days that dipped to minus 10 or lower.
Bismarck, N.D., had 15 days straight with nights plummeting below zero, including five that made it into the minus 20s.
Both Waco and Austin set records for their longest streak of below-freezing temperatures, too. Waco spent more than eight days below 32 degrees.
The cold-weather-related power outages, which are the subject of a congressional probe, affected 10 million people at their peak, the National Oceanic and Atmospheric Administration stated. At least 58 people were killed in Texas, many of them while trying to stay warm.
