Wintry ‘polar plunge’ wallops much of US
WASHINGTON, Feb 15, 2021 (BSS/AFP) – An “unprecedented” winter storm
system will sweep the United States this week, the National Weather Service
warned Monday, with Arctic air driving a “polar plunge” that is expected to
break record-low temperatures.
The coast-to-coast cold front has already pushed its way across Canada and
into parts of northern Mexico, and much of the continental United States has
been shivering under chilly temperatures for days, with about half of all
Americans now under some sort of winter weather warning.
Temperatures have dropped across the country, with only parts of the
southeast and southwest dodging it.
The cold snap has led to heavy snowfalls and ice storms that have caused a
spike in electricity demand and power outages.
Ice on the roads was blamed for several deadly accidents including a 100-
car pile-up in Texas last week that left at least six people dead.
“Over 150 million Americans are currently under winter storm warnings, ice
storm warnings, winter storm watches, or winter weather advisories as
impactful winter weather continues from coast to coast,” the National Weather
Service (NWS) said.
“This impressive onslaught of wicked wintry weather across much of the
Lower 48 (states) is due to the combination of strong Arctic high pressure
supplying sub-freezing temperatures and an active storm track escorting waves
of precipitation.”
At least seven states — Alabama, Oregon, Oklahoma, Kansas, Kentucky,
Mississippi and Texas — have declared weather-related emergencies, CNN
reported.
The NWS described conditions as an “unprecedented and expansive area of
hazardous winter weather” that will set record lows.
“Hundreds of daily low maximum and minimum temperatures have been/will be
broken during this prolonged ‘polar plunge’, with some February and even all-
time low temperature records in jeopardy,” the NWS said.
In a large area known as the Southern Plains that spans parts of Texas,
Oklahoma and Kansas, temperatures are expected to fall as much as 45 degrees
Fahrenheit (25 Celsius) below typical readings for the time of year.
Florida will remain the warmest spot in the continental United States, with
highs above normal and temperatures generally around 80 Fahrenheit (27
Celsius).
