Over 100 million Americans were under fog alerts this week. They stretched from the Canadian border to the Mexican border and into the Northeast.⁣ ⁣ The fog made for some eerie scenes. Watch as a plane disappears into the fog upon takeoff, a train appears from the fog, and ominous fog hangs over the National Mall in Washington, D.C. ⁣ ⁣ #fog #foggy #weather #instaweather #airplane #plane #travel #train #cloud #cloudy #ominous #eerie #washingtondc #reels #reelsinstagram #news #usnews #todaynews
