The first weekend of 2025 is having the coldest air of the season, according to the National Weather Service. The first significant winter storm of the year will impact 62 million people through the weekend and into Monday.

Heavy snow, ice, rain and severe thunderstorms will be unleashed from the Plains to the East Coast. While snow and ice has been limited to the northern states this winter, the upcoming storm will impact areas less prone to winter weather.

“The major winter storm will bring significant disruptions to the Central Plains by late Saturday, spreading to the Ohio Valley on Sunday,” the NWS said.

Travel delays are likely as the storm is forecast to reach the mid-Atlantic by Sunday night. Severe thunderstorms are expected in areas with warmer temperatures. The storm could also impact Texas and Mississippi, which are still recovering from last month’s deadly storms.

States are gearing up for heavy snowfall and hazardous conditions 

A nasty mix of sleet, snow and freezing rain is expected to disrupt travel and daily life in the central United States, according to the NWS Winter Storm Severity Index.

The storm will begin with a deep surge of moist air moving north out of the Gulf of Mexico, which will spread rain and snow over the Plains. As it strengthens and expands, it will track east and spread into the Mississippi Valley and parts of the Midwest on Sunday morning, and reach the East Coast by Sunday night and Monday morning.

Officials have already begun preparing for the worst. On Friday, Missouri Gov. Mike Parson put the National Guard on standby, and Gov. Glenn Youngkin of Virginia declared a state of emergency. Youngkin has urged people to avoid traveling on Sunday.

“I’m encouraging all Virginians, visitors, and travelers to stay alert, monitor the weather forecast, and prepare now for any potential impacts,” Youngkin said in a statement.

States of emergency have also been declared in Kentucky and Arkansas. In Kentucky, Gov. Andy Beshear said in a press conference that emergency warming centers will open on Sunday and people should stay off the roads.

Major cities such as Chicago, St. Louis and Washington, D.C., have also begun pretreating their roads and preparing warming centers.

For those needing to rebook flights due to the storms, American Airlines, Delta, Southwest and United all said they were waiving certain change fees at some locations.

Near-blizzard conditions are expected in the Central Plains 

Heavy snowfall and wind gusts of over 40 mph could create blizzard conditions in the Central Plains by Sunday morning. The region from central Kansas to Indiana may get at least 8 inches of snow, with potential lingering snow showers on Monday.

The NWS Weather Prediction Center said that the most extreme conditions will likely be in places running along the Interstate 70 Corridor, which passes through St. Louis and Indianapolis.

There is also “significant icing potential” mainly in parts of Kansas, Missouri and Kentucky this weekend, according to forecasters. Icing is when rain freezes on contact with the ground. It can also affect cars and car windows — essentially any surface outside.

A thin layer of ice can cause dangerous road conditions for vehicles and pedestrians. Thicker layers of ice can cause power outages and make roads impassable. In 2023, a January ice storm stretching from Texas to Tennessee left hundreds of thousands without power.

Thunderstorms expected in warmer climates

States too warm for snow will also experience extreme weather. Severe thunderstorms are likely on Sunday in parts of Louisiana, Arkansas and Mississippi, according to the NWS Storm Prediction Center.

The Southeast is expected to see the heaviest rainfall, and the storm could cause flooding. There is also an enhanced risk of thunderstorms in parts of the lower Mississippi Valley on Sunday.

This storm is expected to pass by late Monday. It will exit the East Coast on Monday night and fully diminish its impact overnight. But temperatures are expected to plunge on Tuesday. The eastern two-thirds of the U.S. will see temperatures 30 degrees below normal, and the frigid air could last until mid-January.

Your guide to what the 2024 US election means for Washington and the world

Joe Biden’s administration has provisionally approved $8bn in new weapons for Israel in a last-minute show of support for the US president’s close ally after more than a year of war in Gaza. 

The State Department disclosed the sale to Congress late on Friday in what is known as an informal notification, according to two people familiar with the matter.

Such a notification comes before the public announcement of a deal, which will require the approval of the Senate and House Foreign Relations Committees before it can go through.

Axios first reported on the planned sale, which includes $6.75bn in precision guided missiles and small bombs, $300mn in 155mm artillery shells, $600mn in Hellfire missiles and $300mn in Amraam air-to-air missiles, according to one of the people familiar with the matter.

A second person said some of the weapons would come directly from US stocks but many would take a year or more to deliver. 

Israel’s offensive in Gaza has killed more than 45,000 people in the enclave, according to Palestinian health authorities. Israel launched the offensive in response to Hamas’s October 7, 2023 attack on Israel, which killed 1,200 people, according to Israeli officials.

Biden administration officials have vowed to continue to pursue efforts to mediate a ceasefire between Israel and Hamas in Gaza until the end of their term on January 20, but the talks have been stalled for months.

The administration has repeatedly raised concerns with Israel about the humanitarian situation in Gaza but has largely not followed through on threats to withhold weapons.

In November the State Department withdrew a threat to withhold military assistance even after aid deliveries into Gaza fell to record lows, saying it was satisfied that Israel had taken steps to improve the humanitarian situation. 

US officials say aid deliveries have improved since then but continue to be insufficient. Aid groups have repeatedly warned that Israel’s offensive has fuelled a humanitarian catastrophe in the enclave, and called for far greater quantities of aid to be delivered.

Biden has said that he supports Israel’s right to defend itself and vowed to supply it with weapons as part of efforts to deter Iran and its proxies.

Israeli Prime Minister Benjamin Netanyahu has frequently accused the US of delaying weapons and munitions deliveries, a charge the Biden administration denies. 

In November Netanyahu said he had agreed to a ceasefire with Hizbollah in Lebanon in part to help Israeli forces replenish their stocks.

That month the Biden administration informally notified Congress that it planned to give Israel $680mn in precision weapons.

That announcement came after some Democrats in Congress tried and failed to block a $20bn weapons sale to Israel last summer.

Congress approved $26bn in additional wartime aid for Israel in April. That came in addition to the $3.8bn in security assistance the US provides to Israel annually.
