As the nation braces for potentially significant severe weather, millions are on alert for damaging winds and tornadoes this week. A major storm system is expected to bring blizzard conditions and high winds, particularly as the week progresses towards Friday when the greatest threat for severe storms is anticipated. Forecasters are monitoring conditions closely, with warnings already in place for heightened storm activity later this week, including risks of thunderstorms and fluctuating temperatures. While the start of the week will see warm, calm weather, rapid changes are expected, leading to significant weather challenges as spring severe weather season takes hold.
