A bug in the matrix or just the radar? This is no normal cloud-shape, is it?
looks a bit like convective cells to me! they happen in summer (as long as there is sufficient surface heating to drive the convection) - they’re like bubbles in boiling water.
It looks like you’ve got high pressure over there though… the high pressure may just limit the cloud heights and intensity of the precipitation?
Edit: these look a little too big to be pop-up cells, but they still look more convective (instead of frontal). a bit suspiciously too round, though. Do they stay consistent and track across the sky, or are they more bubble-like?
2nd edit: looks like I’m wrong and it is a radar artefact :) (this is why looking at radar timelapses is more important than just single-frames!)
3rd edit: it’s not an artefact, it’s a real signal! it’s insects!
what a roller coaster, and the ominous unexplained insect edit is a cherryon top
aha here’s a full explanation of the thought process:
- no other weather report matches these patterns
- they’re suspiciously round and not blobby like real clouds
- they’re each suspiciously localised around the radars in the network
- there are lots of types of radar artefacts, including close-to-radar ground-clutter (this is what I assumed it was) but it’s too consistent and large of a signal for that
- so it must be something uniform, in the air instead of on the ground, that isn’t rain
- bugs are about the size of a big rain drop! enough to be picked up as a strong signal by the radar and enough to prevent the radar from seeing long distances
- It’s also been flying-ant-day recently across Europe
I don’t know my German geography, but I’d be curious how topology plays into this.
A lot of weather radars have localized noise, I’ve noticed
The screenshot below has only one radar selected. Maybe the app you are using is displaying data from more than one radar?
Oooh, excellent point! The german weather service (DWD, which OP is using) has 17 operational weather radar… looks like an artefact to me!
EDIT: it’s not an artefact, but insects!
Wait, I’m wrong yet again!!! “A bug in the matrix” in the description should have clued me in…
The DWD network is surely more reliable than this, and it’s nice high pressure, so it’s rain-free and plenty of updrafts, so it’s perfect conditions for insects!! They cause enormous signals, no idea why I didn’t think of it first.
(Seen recently in the news in the UK here )
Could be, the app uses RainViewer as source, their sources for Germany are:

The sat 24 IR view doesn’t seem to match up very well with what you’ve posted, so it may just be noise, or a corrupted data load.
But the sateliete image of the above time and location doesn’t really fit either.

Clearly these are map markers for death camps
