October starts with thunderstorms (photos)

Hello again!
October started with great thunderstorms here in North Greece!
While the weather was sunny in the rest of South Greece, many areas where struck by severe thunderstorms in North and South Greece. To be more specific, some Cumulus clouds were developing during the afternoon of the 30/9 and until night many Cumulonimbus had been created all over North Greece.
In Thessaloniki some lightnings were seen from Scopia, but the thunderstorm that appeared came to the city was from West. The first day of October had started with the arrival of a thunderstorm! Some thunderbolts hit the city, which caused some electricity-cuts, but during the storm it didn't rain that much...
Some video-pictures of lightnings
   

A video of the thunderstorm plus a video of a weak thunderstorm at 20/9/07.

The thunderstorm soon ended over Thessaloniki, but the lightnings continued over Thermaikos Gulf whole night.

Next day (1/10) new Cumulus clouds continued to develop and thunderstorms had covered a great area of North Greece. In Thessaloniki Cumulus clouds had become a Cumulonimbus over the mountains (East of Thessaloniki) and it soon started to rumbling during the afternoon. The ambolt of the Cb had covered the sky above my head and light drizzle started.
 

The sky was soon clear after the weakening of this thunderstorm, but new and big Cumuloimbus clouds appeared and they were really scaring. Two Cbs were merged into one and were coming near, as you can see in the Time laspe video below. Unfortunately, this thunderstorm weakened, too and only some rumblings were heard...

All days since then are sunny, but something seems to change from Sunday (7/10)!
If thunderstorms will appear again, new photos will be uploaded!
