Dangerous, prolonged heat is ongoing in the Mid-South to Mid-Mississippi Valley and heat expands into the Northeast for a brief period today. Widely scattered instances of flash flooding due to heavy rains are forecast from northeast Kansas to much of Indiana. Scattered strong to severe thunderstorms are possible across parts of New England, northern Mid-Atlantic, and North Dakota. Read More >

Scattered thunderstorms have developed early this morning for areas along and south of the Highway 34 corridor, which are expected to lift eastward. While severe storms aren’t expected, they will be capable of lightning and torrential downpours. If you are out and about early this morning, be ready to seek shelter ahead of the storms!
Humid and increasingly hot conditions will be seen through Tuesday with heat indices eventually going above 100 degrees. Storms this weekend may temper the heat somewhat before the worst of the heat arrives for Monday. Less humid conditions are expected by late next week.
Isolated to scattered storms will be seen through Sunday with the highest coverage on Saturday. A few storms may be strong to severe with damaging winds and heavy rainfall being the main risks. A flash flood risk exists if storms repeat over the same areas.
Dangerous heat will return Sunday and persist through Tuesday. Peak afternoon heat indices will be above 100 degrees with a very high probability of exceeding 105.
Repeat rounds of storms with locally heavy rainfall are expected through early this evening. The area most at risk is south of Highway 30. If storms repeat over the same areas then flash flooding will be possible.
