Visibility IV / V
The forecast showed a so-called pop-up, with upstairs winds being very moderate and thunderstorms moving slowly. If individual cells happen to merge appropriately, there would be opportunities for a more linear thunderstorm. At first, thunderstorms across Pirkanmaa wanted to go out as quickly as they had. When I was in Valkeakoski in the afternoon, both in the south around Hämeenlinna and in the north around Kuru, the strongest thunderstorms of the day had developed. Both were multicellular thunderstorms. After the draw, I headed north and it was just a good choice. On Sahalahdentie, I reached the southern edge of the strip and for a while the avalanche-shaped shape was visible. Wall clouds have also become observations during the day, but unfortunately at the best stage the visibility to the horizon was not sufficient. While researching the data, I decided to do the first core punch of the summer, i.e. run through the cell core. This is never recommended if you do not know the meteorological criteria and cannot draw conclusions from them about the safety of the case. It was met with heavy hail, occasional gusts of 10-15 m / s and heavy rain. Pretty good continuation for the early summer thunderstorms. Admittedly, it would have been faint to have no intrusion inside, because visually from the edges of the cells the day was not very showy.
