Wall cloud.
No. Tornadoes descend from the base of thunderstorms, usually associated with very tall thunderstorms. The tornado begins in the lower portions of the storm. Furthermore, if the vortex does not touch the ground, it is not considered a tornado.
It varies, but it will always occur during a thunderstorm. If that area of the storm is not obscured by rain or the dark of night you will usually see a rotating block of clouds lowered from the main cloud base called a wall cloud. Near this a downdraft will blast a hole in the clouds. Not long afterwards there will likely be strong winds. Then the funnel begins to lower from the wall cloud and a swirl of dust or debris may appear on the ground below it as the tornado connects to the ground.
The center of a tornado is called the "eye" or "eyewall." It is a relatively calm area with lower wind speeds compared to the strong winds in the surrounding tornado.
If the dew point were lower, it would take longer for rising air to cool to its saturation point. This would result in a lower cloud base. This is also called the lifting condensation level.
stratus clouds are the lowest clouds but cumulus clouds are the white fluffy ones cumulus clouds turn into cumbulimbous clouds when filled but with rain. The only problem is cumulus clouds are not found low!
The air pressure inside the funnel cloud of a tornado is extremely low. The pressure can be significantly lower than the surrounding air, which contributes to the destructive nature of tornadoes as it can cause buildings to implode and objects to be lifted and thrown.

Cloud cover typically indicates lower pressure, as it signifies moisture in the atmosphere which can lead to the development of precipitation. High pressure systems are associated with clear skies and generally less cloud cover.
Yes, the center of a tornado, known as the eye of the tornado, does have extremely low pressure. The pressure in the eye can be significantly lower than the surrounding atmosphere, creating the destructive force associated with tornadoes.
The pressure inside a tornado funnel is lower than the pressure outside. This pressure difference is a key factor in the formation and strength of tornadoes, as the low pressure inside the funnel contributes to the destructive force of the winds associated with tornadoes.
The air pressure in a tornado is lower than that outside the tornado. That is why the wind blows toward the funnel.
Visible signs of a possible tornado often start as rotation in the clouds of a severe thunderstorm, often with a lowered section of the cloud base called a wall cloud. As this happens a cloud of dust may appear near the ground as something called a rear-flank downdraft wraps around the rotation. Then a cone, funnel or elephant trunk shaped projection may lower itself from the cloud base. A cloud of dust and debris under this funnel cloud usually means that the tornado has touched down.
It is not know for certain. One thing that is known is that the pressure is low inside a tornado. The intensity of a tornado is largely determined by the pressure deficit, meaning how much lower the pressure inside the tornado than its surroundings. It is estimated, that a strong tornado will have a pressure deficit of at least 25 millibars, so that if the pressure surrounding the tornado is 950 millibars, the core pressure will be 925 millibars. A violent tornado may have a pressure deficit of over 100 millibars.

Yes,a tornado has air inside even though the pressure is lower.
Iy forewarns because the lower the pressure the taller a cloud can be. So cumulonibuses need low pressure to produce tornadoes and that is why falling pressure can indicate a tornado. I stress the word can.
Air pressures during a tornado can vary greatly, but they typically decrease significantly in the vicinity of the tornado. The lowest pressures are usually found at the center of the tornado, where the most intense winds are located. Pressure drops during tornadoes can be drastic and are often associated with the destructive forces of the storm.
