A significant cold front is poised to bring a dramatic cooldown to the central United States, transitioning the region from summer-like heat to much cooler conditions. The system, propelled by a potent low-pressure area, will sweep across the Plains and into the central U.S. tonight, with effects expected to reach the East Coast by the weekend. Ahead of the front, temperatures are predicted to surge, with highs potentially hitting the 90s, creating a stark contrast to the conditions that will follow.
