Heat will persist across the Central U.S. early this week, spreading into the Ohio Valley and Mid-Atlantic later this week. Read More >

There are some lower probability chances for precipitation over the next few days. After this morning's showers and weak thunderstorms end, the next chance (less than 20 percent) for precipitation is later tonight. The bigger weather story right now is the continued warmer than normal temperatures over the region; expected to persist into the upcoming Labor Day holiday weekend.
There could be a few strong to severe thunderstorms developing over or glancing the far northeast corner of South Dakota into west central Minnesota Thursday night. Right now, that area is under a slight risk (level 2 out of 5) for severe thunderstorms; including 1-2 inch hail and 60-75 mph damaging thunderstorm wind gusts.
