Barry continues to steadily weaken as it moves northward across the Mississippi Valley.

Showers and isolated storms will continue to move to the northeast through this evening. The best chances for rain will be over portions of southeast and east central Missouri, as well as southern Illinois. Most of the activity will only last through late this afternoon, then begin to scatter out through the evening hours.
Heat still looks to intensify beginning Wednesday and only gets hotter Thursday through Sunday. Heat index values between 100 and 110 degrees will last from the late morning through the early evening hours each day. The heat index may exceed 110 degrees in urban and inner city areas. This would be the hottest weather thus far this summer and could last beyond next weekend.
