Millions of Americans from the Plains to the mid-Atlantic will need to keep an eye on the sky on Sunday as periods of unsettled weather will bring the chance of severe weather.
The threat of severe weather comes as dangerous heat that has been felt across the South will expand to the east, putting more than 70 million Americans at risk of heat-related illnesses over the next few days.
The threats on Sunday include large hail, damaging wind and possible tornadoes.
Let's start off in the eastern half of the country.
As we stated above, severe weather is possible from the Plains to the mid-Atlantic, but there is a higher risk of severe weather in central Virginia into north-central North Carolina. Cities included in that treat are Richmond and Roanoake in Virginia and the Raleigh area in North Carolina.
Heading further west, thunderstorms and severe weather is possible from the Ohio Valley to the Plains.
However, there is a higher chance of severe weather in southern Indiana, southeastern Illinois and western Kentucky.
Cities included in that risk are Paducah, Kentucky and Indianapolis.
In the Plains, the higher threat of severe weather extends from the Dakotas through central and western Nebraska and into parts of northwestern Kansas.
That means people from Bismarck, North Dakota, south through Rapid City, South Dakota, North Platte, Nebraska and Colby, Kansas need to keep an eye on weather conditions during the day.
Let's break down each type of severe weather on Sunday.
Tornadoes are possible across the Dakotas, as well as extreme northwestern Minnesota and parts of southeastern Montana and northeastern Wyoming.
The threat of tornadoes also exists from Iowa across parts of the Great Lakes and into the Ohio Valley.
The threat of large hail exists from the Northern Plains to the Carolinas, but areas expected to see a higher threat include southern Indiana, western Kentucky and southern Illinois.
Large hail is also likely from parts of western Minnesota and the Dakotas into the Central Plains.
And there is the potential for hail larger than 2 inches in some locations.
That threat extends from southeastern Montana and northeastern Wyoming into western South Dakota, Nebraska and northwestern Kansas.
The same areas under the threat of possible tornadoes and large hail will also be under the threat of strong, damaging winds if severe storms develop.
In addition, central Virginia and north-central North Carolina will also see a higher threat of damaging winds from severe thunderstorms on Sunday.
