Severe thunderstorms will continue to threaten the Ohio Valley and parts of the central Appalachians through Wednesday evening.

St. Louis, Cincinnati and Louisville are some of the major travel hubs at risk of having severe thunderstorms through Wednesday evening.

This can result in a plethora of travel delays at the airport and on the roadways, especially if a thunderstorm rolls through one of these cities during the Wednesday evening commute.

In addition to the strong winds and large hail, thunderstorms that track across this area will also produce torrential downpours that can lead to localized flash flooding. A very isolated tornado cannot be ruled out.

Anyone behind the wheel during these downpours should take extra precautions as the heavy rain can make it more challenging to drive.

Hydroplaning is an added danger when driving in these downpours as water can pool on roadways and make you temporarily lose control of your vehicle.

Driving at a slower speed or pulling over to the side of the road until the storm has passed are just two ways that you can reduce the chance that you become involved in a weather-related accident during a blinding downpour.

Wednesday's severe weather will not be limited to the Ohio Valley and central Appalachians.

Additional thunderstorms will develop over the central High Plains through Wednesday evening and track into northern Kansas and Missouri at night.

Tornadoes will be an added danger when it comes to these storms with the highest probability for tornadic development occurring during the late afternoon and early evening.

One tornado tracked through the eastern suburbs of Denver Wednesday afternoon.

Those around Denver; Cheyenne and Casper, Wyoming; North Platte, Nebraska; and Salina and Goodland, Kansas, should all be prepared if one of these severe storms impacts your community.

The threat of severe weather will decrease in the East heading into Thursday. However, a few gusty storms are still possible across Kentucky and Tennessee with a separate area across the Delmarva Peninsula and Washington, D.C.

Farther west, severe weather is forecast to develop once again, focusing from the Texas Panhandle into western Kansas.

The biggest threat with storms that develop late on Thursday is expected to be large hail, possibly as large as baseballs.
