Dissipation stage
During the afternoon the cells weaken as shown in the picture of 14.30 UTC: radar reflectivity has also significantly decreased (no red colour in the radar image).
Satellite imagery also shows a significant decrease in cloudiness. At that time the weather activity is less intense although showery precipitation is continuing but without hail.
