There are two forces at work here. The more 'northern' air mass which can be noted as 'moving' in the '12 hour loop' at the title to the entry is the jet stream. BUT. The jet stream is not moving the 'heat transfer system' coming off the equator.
The 'heat transfer system' which is bringing all the 'weather' to the USA and all the turbulence is the lower, very sluggish air mass. Now, I know others understand this, so what is causing the sluggishness of these heat transfer systems?
Don't know? Sure. It is easy. If Earth has an air mass that is over the Equator and it starts to move with the Earth spinning 'under' it, what then is causing the 'sluggishness' to the air mass as it has no driving winds?
Clue: Horse Latitudes.
The Coriolis Effect.

The air mass west of the Baja Peninsula is going to follow the same path across the nation as the last air mass that carried all the tornadic winds with it.
As these 'slow air masses' move with the driving force of the Earth spinning, there is a reverse effect. The air mass DOES have mass. It does have friction. The friction between Earth and the air mass facilitates the movement of the air mass. What does that mean, when a sluggish heat transfer system interacts with Earth to find its impulsion?
The friction between the air mass, OVER TIME, will retard the spinning of Earth and it slows. This is Human Induced Global Warming. We need to deal with it, NOW !
