A massive cumulonimbus cloud built up just east of Indianapolis, a lone thunderstorm illuminated by the setting sun.

It was isolated, but parts of Hancock and Rush counties got some much-needed rain from the storm, which hovered in the area for about an hour before dissipating, as seen from the Storm Shield app.

For some, the top of the cloud took on a heart shape. For others, it looked like a mushroom cloud.

Residents snapped pictures of the cloud and sent them to RTV6 through Facebook and uReport.

"The Cloud: Part 2" came less than two weeks after the original. On the Fourth of July, a thunderstorm that rumbled through Shelby County at the end of the day also had a massive cumulonimbus cloud that was lit up by the sun.

Monday night's cloud was visible from all over the region, too, and it stood out because it was the only cloud in the sky on what was otherwise a steamy evening as temperatures dropped from a high of 98 in Indianapolis.
