In today's newsletter: A U.S.-brokered ceasefire between Israel and Hezbollah takes effect. Winter weather is forecast for Thanksgiving. And Hallmark and the NFL team up for a Kansas City Chiefs-themed rom-com.

Here's what to know today.

A United States-brokered ceasefire deal between Israel and Hezbollah in Lebanon has taken effect a day after President Joe Biden announced the agreement. Under the deal, which went into effect at 4 a.m. local time, the fighting at the Israel-Lebanese border was to come to an end. Biden said the ceasefire was "permanent" and said the U.S. and its partners “will make sure the deal is implemented fully.” Earlier Tuesday, Israeli Prime Minister Benjamin Netanyahu said in a statement that his Cabinet had approved the U.S.-brokered deal, 10 ministers to one.

In addition to the widening risk of a regional war, the escalated tensions and back-and-forth strikes over the last year killed dozens of people in Israel, hundreds in Lebanon, and displaced tens of thousands on both sides of the border.

Iran-backed Hezbollah had said it was supporting the Palestinian resistance in Israel’s military offensive in the Gaza Strip; Israel saw it as another attempt by Tehran to attack the Jewish state. Israel has also killed several of Hezbollah’s most powerful leaders, including influential leader Hassan Nasrallah.

Now, Israeli troops will start withdrawing from Lebanon. The troops will hold their positions and a 60-day period will start in which the Lebanese military and security forces will begin their deployment toward the south, a senior U.S. official said, adding in 50 to 60 days, all Israeli troops will be gone.

'Arctic outbreak' forecast for Thanksgiving

Dozens of flights were canceled and thousands were delayed yesterday over shortages of air traffic controllers and weather. At Newark Liberty International, the FAA issued a ground delay through early this morning.

Meanwhile, the National Weather Service warns that a pair of weather systems were expecting to bring an “Arctic outbreak” across parts of the U.S. into the weekend. Temperatures in the Great Plains are expected to only hit the teens and 20s today. In Central and Southern California, the Great Basin and the Rockies, an atmospheric river event was set to bring rain and, in some places, snow. Parts of the upper Michigan peninsula are expected to get snow. And rain is in store for New York City. Here’s what else is in store for holiday weather and travel.

The obscure ICE program setting up deportation battles

President-elect Donald Trump’s administration is expected to employ a little-known Clinton-era policy to help carry out the mass deportations that he promised throughout his campaign. The policy, known as the 287(g) program, allows Immigration and Customs Enforcement to give state and local law enforcement officers the power to perform certain functions of an immigration officer. Once trained, local corrections officers can check the immigration status of a suspect arrested for a crime and transfer them to ICE custody for deportation.

Defenders of the program say it doesn't empower local police to round up undocumented immigrants on the streets. “If they’re brought in — they’re arrested for something that they have committed, an act they’ve committed against the citizens of our community,” Harford County, Maryland, Sheriff Jeffrey Gahler said. “And at that point, they’re held accountable for the action of being in the country illegally.”

Critics say the program amounts to racial profiling while instilling fear in immigrant communities, and some say it merely serves as a political messaging tool for conservative police chiefs and sheriffs.

Trump has promised to require local cooperation with federal immigration enforcement. But many elected Democrats are vowing to defy his administration’s mass deportation efforts, setting the stage for a future clash. Read the full story here.

Guess who (sort of) inspired this NFL-themed rom-com

While Swifties are taking a newfound interest in football amid Taylor Swift and Travis Kelce’s high-profile romance, the NFL is leaning into Hallmark’s holiday rom-com audience with a Kansas City Chiefs-themed collab. I talked to the cast of Hallmark’s “Holiday Touchdown: A Chiefs Love Story,” which premieres this weekend, about what it was like filming at Arrowhead Stadium — the Chiefs’ home base where Swift and Kelce’s love story reportedly began — and being on set with beloved NFL mom Donna Kelce.
