MCS 29.06.2017

At first I want to apologise, because my English isn't very good. If you want, you can write in the comment, what I should correct.

Beginning

I'm woke up at 6 am and started preparing to work. It was holidays, so I'm working with a stepfather on a construction site, to earn some money. Weather was good, it was sunny and warm day.

Warning

It was 12 am when I received notification from messenger. These were my stormchasers friends, they told me that I should prepare for incoming storm. I opened meteo radars and saw this.

Green arrow shows where I live (and where i was then), blue arrow shows the direction of moving storm.

I told my stepfather thah we should go home, because whet this storm will come we won't be able to work anymore in this day, and this storm will be probably strong. He agreed with me, and we went home at 1 pm.

Incoming

As fast as I could I get my camera, tripod and I went to my view point. This was under the train bridge. I set up camera for taking photo sequence for time lapse. This is how it looks on radar.

And how it looks.

Impact

This storm was moving very fast, with rapid condensation in front of it. This is how it looks in few next frames.

When the storm hits, the wind was unreal, very strong with a lot of precipitation. There was also a hail (green colour of precipitation in incoming storm mean that there is probably hail). I hide under the bridge and just was recording this.

Evolution

This storm developed to large MCS (mesoscale convective system). But lets start from the begining of it's existence.
First time when we see this storm on the radar, it is in Slovakia territory at 8:40 am.

When it comes to Poland it almost disappeared at 9:50 am.

But suddenly it developed to this level at 10:50 am.

At 11:30 am it was at this level, still developing.

When the storm was above me, It was huge already.

At 4:50 pm covered a huge part of Polish territory and couse a lot of damage.

And it leave Polish territory at this level at 5:50 pm.

Rest of the day

After this MCS at 7:30 pm some small storm cells are developed.

And I took some photos of them.

One of them looks like supercell with wall cloud, but this wasn't SC :(

I saw monster shel cloud in the distance.

At the end small roll cloud are created.

Summary

That was very dynamic day, with powerfull, and beautifull storm (but also very dangerous). After main storm some small but also nice storms, and nice roll cloud.

I made a video about this day, you can see this here.
