A resident of St. Louis took an awesome time lapse of a strong thunderstorm rolling across his neighborhood yesterday. The storm bubbled up on the horizon before racing towards the camera, developing an awesome shelf cloud along the way.

CBS News published an article this afternoon reporting on a super rare "sideways tornado" spotted in Maryland. The only problem is that there is no such thing as a sideways tornado, and apparently CBS has no meteorologists (or elementary school graduates) on its payroll to fact check this sideways article.

Myrtle Beach, South Carolina meteorologist Ed Piotrowski posted this pretty cool time lapse video of a shelf cloud moving rolling across the shore on Friday afternoon. Shelf clouds are formed by warm air rising along the leading edge of thunderstorm's cooler gust front.

CTV Toronto caught this awesome picture of a shelf cloud as it moved over the city's skyline this evening. Severe thunderstorms swept across parts of southeastern Michigan and southern Ontario today, producing dozens of reports of wind damage.

Shelf clouds are a stunning feature of many spring and summertime thunderstorms that often pack more bark than bite. Other than for their incredible beauty, shelf clouds are usually newsworthy because they tend to freak people out.
