More recently, a so-called bomb cyclone struck northern California in 2019, and the frigid New York City temperatures in 2018 (as cold as 19 degrees Fahrenheit) forced attendees at the Macy's Thanksgiving Day Parade to bundle up.

Winter weather could snarl travel plans for the millions of Americans traveling for the Thanksgiving holiday this year.
