Update at 4:55 a.m. EDT Thursday:

This blog is no longer live, as the threat for severe weather has diminished. However, some thunderstorms still continue from the Ohio Valley into the Plains. Detailed reports of the event can be found below.


Powerful thunderstorms rumbled across areas of the Ohio Valley and the Plains back into the Rockies, triggering tornadoes, large hail, dangerous lightning and flooding rains on Wednesday into Thursday morning.

Tornadoes were reported near Aurora, Byers and Leader, Colorado, with hail and a tornado warning causing flight delays to Denver International Airport.

Tornadoes also touched down near American Falls, Idaho; Wheatland, Wyoming; and Voda, Kansas.

Thunderstorms that tracked across the region also produced hail up to baseball size and torrential downpours that led to localized flash flooding. A very isolated tornado cannot be ruled out.
