Tornadoes are very often accompanied by hail, but not always. In many cases that hail comes before the tornado.
Hail forms in thunderstorms when updrafts carry raindrops into cold regions of the atmosphere where they freeze into ice pellets. These pellets grow as they are lifted and fall to the ground when they become too heavy for the updrafts to support.
No. Tornadoes are too numerous and happen too quickly to be named. Instead tornadoes are usually referred to by the places they hit, such as the Oklahoma City tornado or the Tuscaloosa, Alabama tornado. The only types of storms named are tropical cyclones (e.g. hurricanes).
Hail is created when supercooled water drops come in contact with strong winds from thunderstorms. The water is pushed into higher altitudes where it freezes. It then falls to the ground as hail before it melts back to rain.
I too have tried to answer this, I have looked and come to this answer. There have been some hit outside of the Duncan proper area, but so far as I can find none in Duncan proper as far back as 1890.
Hail happens in areas with many cumulonimbus clouds, or an area where thunderstorms or tornadoes are most likely to happen. Hail forms in clouds, and the more water the cloud has absorbed, the bigger the hail pellets are going to be.
Tornadoes are not named. There are too many of them for any sort of naming system.
Tornadoes are not named. Tornadoes are too short-lived for a name to be useful, and there are simply too many of them for any naming system to work.
No, tornadoes are not named. Unlike hurricanes tornadoes come and go too quickly to be named and there are far to many of them for there to be any semblance of an effective naming system.
It is too early to tell for sure, as there is always uncertainty in these outlooks, but the fact that there is a moderate risk outlook and the potential for tornadoes has been mentioned, a few strong (EF2+) tornadoes may be possible. However, the oulook states that the primary threat is expected to be hail.
Tornadoes are not necessarily dark, though they are often opaque. Tornadoes occur during severe thunderstorms and the clouds of such storms often block a significant amount of sunlight. The condensation funnel is essentially a part of the cloud and will appear a similar color. However tornadoes that are front lit can appear light gray or even white. Tornadoes can also lift up large amounts of soil, which changes the color of the tornado. If the soil is dark, the tornado will be too.

Mostly, around when tornadoes hit it hails. But it does vary too. From hail, to rain. However, the tornado itself does not produce the precipitation: the parent thunderstorm does. Often a tornado is found in a precipitation free area of a storm.
Tornadoes do not have names. Australia has had many tornadoes, too many to list here.
Hail typically comes from cumulonimbus clouds, which are large, towering clouds associated with thunderstorms. These clouds have strong updrafts that can keep hailstones suspended until they become too heavy and fall to the ground.

Antarctica is too cold for tornadoes to form. Tornadoes need energy from warm air.
During a tornado, or before the wind picks up and the sky may get very dark. Sometimes the sky can even turn green. Tornadoes mainly happen in severe thunderstorms, so sometimes there can be hail too.
