Tornadoes are almost always a accompanied by rain shortly before or after they strike if not during. Though in some cases they can be produced by LP (low precipitation) supercells which have little to no rain.
Sometimes but not always.
Tornadoes are usually preceded by heavy rain and sometimes large hail as well a thunder and lightning. The rain often stops before the tornado hits, but not always (in which case it is called a "rain wrapped" tornado).
Yes. If a tornado is rain wrapped rain can be drawn into the circulation.
Since tornado typically form in the rear portion of a thunderstorm they are usually preceded by, thunder, lightning, heavy rain and sometimes hail. This does not always stop before the tornado arrives in which case it is said to be rain wrapped.
Tornadoes are often, but not always, preceded by heavy downpours, which may or may not stop before the tornado strikes.
No. Rain does not cause a tornado. However, both rain and tornadoes are caused by thunderstorms.
A tornado that is surrounded by rain is said to be rain-wrapped. Rain-wrapped tornadoes can be especially dangerous because they are difficult to see.
The Joplin, Missouri tornado of 2011 was what is known as a rain-wrapped tornado, meaning it was surrounded by heavy rain. This rain obscured the tornado from view and may have contributed to the extremely high death toll.
The tornado itself did not produce rain. But Springfield did get some rain from the system that produce the tornado.
Tornadoes are accompanied by rain, but they do not produce it themselves. Rather, the rain is a product of the thunderstorm that spawned the tornado. Hurricanes produce very heavy rain.
Usually a tornado come after rain, as most tornadoes are located in the rear portion of a supercell.
A tornado itself does not produce rain, but it can accompany a tornado. The storms the produce tornadoes, called supercells typically produce very heavy rain, often enough to prompt flash flood warnings. This rain may stop before the tornado comes, or the tornado may be rain wrapped. Some storms however, called LP (low-precipitation) supercells produce little to no rain at all, but can still produce tornadoes.
