Severe storms eyeing the Chicago area Tuesday have the potential to produce supercells, considered to be one of the most powerful types of storm. But what exactly are they and what makes them so dangerous?

Supercell thunderstorms and tornadoes brought devastation to several central states earlier this week, and the danger is far from over.

As the Central and Eastern US begins to rebuild after back-to-back weeks of severe weather, we break down why the storm across northern Illinois and Indiana was so strong.

Editor’s Note: Wednesday afternoon, the National Weather Service confirmed at least one tornado touched down Tuesday near Wheatfield, Indiana, with peak winds near 110 mph, ranking as an EF-1 in intensity.

A NWS storm survey has confirmed an EF-2 tornado in Starke County, IN west of Knox. This tornado is associated with the same parent supercell that spawned the Kankakee, IL-Lake Village, IN EF-3 tornado and the Wheatfield, IN EF-1 tornado on the evening of March 10th.

Weather experts explain the science behind the rapidly-developing twisters, and how just the right conditions had to be in place for it to happen.

Following Tuesday's destructive tornadoes, more severe thunderstorms are now sweeping eastward through the South and the mid-Atlantic states. Get the latest on the severe outbreak's impacts and forecast here.
