Supercell thunderstorm that formed on top of me,14th april belgrade 2023

It was first potential of supercells and organized convection in my country,i left house with hope that i will see something good,around 3 pm i noticed counter clock wise rotation above me(i have vid of it too),cloud later grown around 10 km vertical and radar reflection wasn't that strong it was around 57 dbz.Indeed pretty good day for me.
