Is there a way to detect a tornado before it gets too obvious?

Like I mean is there a way that people know when a tornado will come, before it forms? People who live in places where tornadoes are frequent probably have ways of knowing this, and professionals can definitely tell ahead of time.
I mean seems easy to me; if shit starts getting windy, but…violent winds always happen without tornadoes.
What are telltale signs that a tornado is coming? The color in the sky? Dropping/rising pressure, is there a way to detect tornado wind from other winds before the actual tornado is formed, besides the violence? Is there always a storm present? Or do people just know due to weather forecasts and issued warnings? What kind of weather occurs before the tornado comes? How much ahead of time is it possible to tell?

I’m not expecting a tornado, nor have I ever witnessed one. Just curious. This is actually pretty random.
