Extreme Weather Alert: Heat Wave and Severe Storms Threaten West Coast and Plains States

Severe weather, including possible tornadoes and flash flooding, is expected in a huge part of the Heartland on Thursday, while an early season, summer-like heat wave from Seattle and Portland, Oregon, into central California is expected over the weekend and could bring major, record-breaking heat. Nine states are also under flood alerts from Montana down to Mississippi. Record highs are possible for several days straight in the Pacific Northwest over the weekend and into early next week.
