Most of the United States is being assailed with extreme winter weather
this week as Arctic air blasts south from Canada, snow tracks up the
Northeast coast and a potentially crippling winter storm takes aim at the South.

Travelers are facing delays Sunday and cold is in store for much of the
nation, with more than 75% of the US expected to face freezing
temperatures this week.

Over 70 million people are under winter weather advisories and winter
storm warnings from Tennessee to Maine on Sunday. That means snow for many Northeast cities, as a low-pressure system will bring a quick shot of snow
to the I-95 corridor from Virginia to Maine on Sunday through early
Monday.

Washington, DC, is expected to see 1 to 3 inches of snow, with up to 6
inches expected in New York and Boston. Hartford, Connecticut, could see 5
to 7 inches of snow and Portland, Maine, could receive up to 8 inches. And
in Philadelphia, where a snow emergency was declared Sunday evening, there could be 4-6 inches of snow and below freezing temperatures Sunday night.

A cold weather emergency has been activated in Washington, DC, mayor
Muriel Bowser announced in a Sunday post on X. The mayor warned of
“dangerously low” temperatures overnight. The frosty forecast prompted the announcement that President-elect Donald Trump’s inauguration will be held indoors on Monday, the first inside presidential inauguration since Ronald Reagan in 1985.

At least 1,100 flights into or out of the US were canceled by Sunday
evening with another 5,017 delayed, according to the flight-tracking
website FlightAware. Over 20% of flights into or out of Newark Liberty International Airport and LaGuardia Airport were canceled, the site shows.

New Jersey Gov. Phil Murphy declared a state of emergency due to the
storm.

“As always, I urge all New Jerseyans to use caution, follow all safety protocols, and remain off the roads unless absolutely necessary,” Murphy
said on X Saturday.

Meanwhile, the South is bracing for a rare winter storm with a still-
uncertain forecast. Louisiana declared a state of emergency and Texas has directed state agencies to mobilize resources due to the threat of snow.

In Houston, Texas, both civilian airports will be closed all day on
Tuesday, mayor John Whitmire announced at a Sunday evening news
conference. Schools in the Houston Independent School District — the
largest in the state and the eighth-largest in the country — will also be closed until Wednesday, Whitmire said.

The city could see up to 5 inches of snow starting Monday night, according
to National Weather Service Houston, which warned of “freezing rain” and
icy roads making for dangerous travel conditions into midday Wednesday. Below-freezing overnight temperatures are expected to continue from Sunday through Friday, says the agency.

Dangerous cold for millions
Arctic air spreads across much of the US this week, and for some states,
the extreme cold could last for days. Nearly 150 million people are under
cold weather alerts with forecasters warning of potential frozen pipes, frostbite and travel delays.

More than two dozen record lows are possible this week including in
Cleveland, Kansas City, and Houston as temperatures will drop 20 to 30
degrees below normal.

Denver is forecast to have a high temperature of only 9 degrees Monday, a staggering 36 degrees cooler than their normal high of 45.

Southern cities such as Atlanta, Charlotte, Memphis and Birmingham may not
even reach a high temperature above freezing Monday and Tuesday.

“An extended period of freezing temperatures could cause ruptured water
pipes,” the National Weather Service in Atlanta warned.

Houston’s mayor similarly urged residents to protect their water pipes
before the frigid temperatures hit. “Let me emphasize the preparation of
your pipes,” Whitmire said Sunday. “Wrap your pipes if all possible.”

The mayor said that he was “convinced that we are about to experience a
very serious and dangerous weather episode.”

He urged residents to stay inside, to check on vulnerable neighbors and
family members, and to utilize one of the city’s 24-hour warming centers. Officials are doing “everything we can” to encourage homeless people to
seek refuge in warming centers, he added.

Wind is also a huge factor in the cold. Wind speeds of 15 to 25 mph, along
with the already very cold temperatures, will lead to wind chills of minus
25 to 50 below zero at times from Sunday to Tuesday across the Midwest and Northern Plains. These conditions could cause frostbite on exposed skin in
less than 10 minutes.

‘Rare, significant winter storm’ for South
More than 30 million people from Texas to Georgia are under winter storm watches in preparation for a rare winter storm across the Gulf Coast and Southeast this week.

The impacts from the significant storm will begin in Texas on Monday, the Weather Prediction Center said, adding that major traffic and travel disruptions are likely through mid-week.

A wintry mix of snow, sleet, and freezing rain is expected near and south
of the Interstate 20 corridor with potentially heavy snow or sleet in some areas. The sleet and freezing rain could stretch as far south as the
Interstate 10 corridor.

The latest forecast shows the potential for at least 3 inches of snow in
Baton Rouge and Lake Charles, Louisiana; Hattiesburg, Mississippi; Macon, Georgia; Montgomery, Alabama and Houston, Texas.

Ice accumulations could also lead to power outages and downed trees.
