The is additional air turbulence at the border of Iowa and  Minnesota. Same kinds stuff. Temperature variation.

Same as yesterday, everything is moving very fast. What a mess.

Ya know, that entire 'air ridge' is starting to look like a roll cloud phenomena. See that? There is an underlying current with upper level movement to reinforce the lower air circulation. It is starting to take on the appearance of a tropospheric roll cloud without the dense water vapor mass. There have been occasional phenomena like this before and they are on this blog. It is just that with winds entering from both the southwest and southeast the velocity will really pick up.

The less the water vapor the more concentrated the accumulation and the more likely tornadoes.

Jet Stream. It is really sailing along. Odd.

It is a single phenomena with the Jet Stream removing some of the water vapor. The Jet Stream can't compete with it. There is a tropospheric disturbance.

There is the system. The southern border extends west out of the image along the Equator. It is receiving hot wet air from the Equator and delivering it right into the Arctic regions.

It is continuous. The Jet Stream can be noted moving across Mexico and New Mexico. The Jet is carrying water vapor off the primary system resulting in a darker color. The Jet Stream for as fast as it is moving can't even dent the main tropospheric system.

Hurricane season is about two weeks away. I think it will be a strong Pacific season that crosses into the Gulf. Whatever.

The sooner the hurricanes start the sooner the threat of tornadoes will abate. Hopefully. I noted a strong circulation center in the Atlantic a few days ago though. I thought that might be the first storm of the season, but, the Hurricane Center didn't bother with it because it was in the Atlantic and didn't effect land. I don't think that is the right call. It was definitely a tropical depression.
