Heavy rainfall from scattered thunderstorms is expected across the Southwest, Intermountain West, and Plains. Isolated dry thunderstorms may initiate additional fires across the west. The coastal Carolinas may experience flash floods in the coming days due to repeated thunderstorms. Additionally, a wave of intense summer heat will hit the Southern Plains and central Gulf Coast States this week. Read More >
Overview
|
A large storm system and strong Arctic cold front brought accumulating snow, gusty northwest winds and dangerously cold wind chills to the region. This resulted in widespread ground blizzard conditions to much of the Northern Plains. Dangerously cold wind chills below -35F were also in place resulting in life-threatening travel conditions for the days leading up to Christmas. Numerous highways and interstates were closed with some travelers becoming stranded, requiring rescue. This front pushed southward through the entire southern United States, bringing multiple weather hazards and abnormally cold temperatures to the eastern 2/3rds of the CONUS. |
