California is facing more extreme weather, while the powerful winter system that had earlier triggered record rainfall, heavy snow and flooding in the Golden State was threatening the Plains with powerful winds and tornadoes Sunday night.
The big picture: The National Weather Service tweeted Sunday evening that the first of two new storm systems hitting northern California with rain and snow was causing "dangerous travel conditions," with blizzard warnings to take effect early Monday in the Sierra Nevada — where 4 to 7 feet of snow was set to fall this week.
