Summer clouds and thunderstorms in November! (photos)

And this is the video, showing lightnings from the thunderstorms yesterday.
The first lightnings are from the huge multicell towards East Macedonia and Thraki (Kavala, Serres, Rodopi etc), that also caused floods and many damages. And the rest of the video shows the thunderstorm, that was developed ~2:30 over Thermaikos with rainfalls and hail.


The beginning of the following day was interesting, too. Summer clouds and Cumulonimbus were surrounding Thessaloniki and the most of them were towards East.
As I was having a walk to wach the beautiful Cbs, I suddenly noticed the optical phenomenon called parhelia. The clouds left of the sun had some rainbow colours.


Then, I saw some Cumulus clouds hidding behind the mountains North of Thessaloniki...

...and thunderstorms towards NW far away.
   

Later, a huge and fascinating Cumulonimbus incus was getting closer from SE! 

But unfortunately, it was dissolved into those Altocumulus clouds some hours later.
