What is happening on weather radar?

Does anyone have any idea what this is?

Looks like 'spotty" showers? Lol JK.  I live in the vicinity of the top map. It's cloudy and humid here.  Maybe it's showing the clouds outside of the rain/storms.

Ground clutter or fog. The radar you are watching a video of is not calibrated correctly or is just set to see everything.

....and it's 86 degrees Fahrenheit here, and it feels like..., they say 95.  It might as well be 500 degrees.   Maybe that is showing the humidity.

I noticed the same thing as well. Clouds appearing out of nowhere. Disappearing just as fast. Wind patterns are off. Southeast Asia is receiving an unusual amount of rain. Tropical storms appear and disappear within a day.

Cloud Seeding in progress!!!!!!
They are "proving" CO2 Climate Change!!

This happens a lot apparently.   

I think all the blue ones are anomalous propagation

Seeing numerous radar sites simultaneously displaying anomalous propagation (AP) across a large area, like across the country, is often linked to widespread atmospheric conditions that promote superrefraction and ducting. These conditions are frequently associated with: 

• Strong low-level temperature inversions: A temperature inversion happens when a layer of warmer air sits above a layer of cooler air, which is the reverse of the typical atmospheric temperature profile. This commonly occurs during clear, calm nights, when the ground cools quickly by radiating heat, and the air immediately above it also cools, while air higher up remains warmer.

• Sharp decrease in moisture with height: When a strong temperature inversion is present, especially when combined with a rapid decrease in moisture content as altitude increases, the refractive index of the atmosphere changes significantly, leading to the bending of radar beams. 

• Superrefraction causes the radar beam to bend more downward than normal due to changes in atmospheric density (which affects the refractive index).

• When this bending is extreme, the radar beam can be bent so significantly that it follows the curvature of the Earth, or even gets trapped within a layer of the atmosphere. This extreme form of superrefraction is known as ducting or trapping.

• As a result, the radar beam, intended to scan the atmosphere for precipitation, instead hits the ground or other objects at a distance beyond the normal radar horizon, creating false echoes, or anomalous propagation.

If you're referring to the clouds, it is a computer-generated representation of clouds, or what-to-call-it ... a probability cloud.  yuk yuk   .   Many radar representations are overlayed on visible satellite views, often with state/country lines.  If you look at that same area at, say, Zoom Earth, you still see a computer-generated image, but one that is based upon the visible satellite.   NOAA, Windy, same thing.   

This is a great thing that you pointed out;  radar anomalies are frequent, and sometimes quite entertaining....... and I think it's important to watch.   You just never know.  We could see a mothership crossing the nation, and the majority of people would be debunking it.  

weather nerds unite.

These radar images. are not the classical radar output...

These are heavily subject to algorithms and tweaking (for our benefit) so we can "see" the weather visually.
Add to that a rather circuitous routing (native only to weather and flight control systems) who knows what might or might not be an artifact or something we should worry about.

If we had different overlapping systems it might be easier to rule that out.

Just 'thinking out loud' here...

Looks like clouds forming over large city population centers. A comparison with a map that shows the towns and cities would show if this is what is happening.

After a second take, those circles are centered on the radar units. I recognize the ones in the lower Michigan that cover Cadillac, Grand Rapids and Metro Detroit. You can see the radar line radiate from the center and rotate for a frame or two in the circle. That what that is, I'm sure of it. The other circles are doing the same thing.
