(KFVS) – The National Weather Service has issued a special weather statement for possible landspouts, weak tornadoes and/or funnel clouds.
This is for parts of southeast Missouri, southern Illinois and western Kentucky.
They say there have been reports of funnel clouds and landspouts on Monday afternoon, July 8. They’re developing underneath thunderstorms moving across the area.
According to NWS, these funnels usually are very brief and seldom touch the ground. If they do touch down, they say they will be very weak and will most likely not cause damage.
The NWS defines a landspout as: “a tornado that does not arise from organized storm-scale rotation and therefore is not associated with a wall cloud (visually) or a mesocyclone (on radar). Landspouts typically are observed beneath Cbs or towering cumulus clouds (often as no more than a dust whirl), and essentially are the land-based equivalents of waterspouts.”
According to the NWS website, a funnel cloud is “a condensation funnel extending from the base of a towering cumulus or Cb, associated with a rotating column of air that is not in contact with the ground (and hence different from a tornado). A condensation funnel is a tornado, not a funnel cloud, if either a) it is in contact with the ground or b) a debris cloud or dust whirl is visible beneath it.”
They define a tornado as, “a violently rotating column of air, usually pendant to a cumulonimbus, with circulation reaching the ground. It nearly always starts as a funnel cloud and may be accompanied by a loud roaring noise. On a local scale, it is the most destructive of all atmospheric phenomena.”
