Visibility IV / V
The summer 2021 thunderstorm season opened. The models looked like the so-called. shortwave to be on the southwest side and intensifying upstairs winds significantly. This would know harder thunderstorms if only it were clear and the sun could properly intensify the occurrence of thunderstorms. However, for a long time Cloudiness was a nuisance, when the thunderstorms that arose were very mumbling, but still yielded a few decent lightning strikes. This said there was enough power upstairs. My time when I watched mosses in Northern Pirkanmaa and Jalasjärvi was drawn to the clearer area to the west. Here, my own cumulus cloud had already begun to rise. The beak towards Kauhajoki and the best moment of the day got to start. There was a spectacular avalanche cloud and intermittent rotation at the front edge of the resulting thunderstorm. On the leading edge of the thunderstorm, towards Kurikka, where the avalanche began to lose its shape. The lightning was pretty lazy, but the few lightning strikes were mostly decent ground shots. By the thunderstorm day of May, this eventually turned out to be quite good, because in Finnish thunderstorms in Finland, similar shapes do not always appear in the clouds.
