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
|
Scattered thunderstorms developed by late afternoon across southeast South Dakota and slowly moved eastward into the evening hours. Some of the stronger storms produced hail up to the size of golf balls. By late evening, an additional round of storms began to develop and prompted several warnings for damaging winds, large hail and flash flooding into the overnight hours. |
