The NOAA-19 AVHRR (0.6, 0.9, 10.9 µm) image, from 2 May at 11:32 UTC, depicts shallow convection around the Baltic Sea.

In May the sea is still cold, and convection can only be triggered over land. In the Metop-B image, taken earlier at 08:38 UTC, sea ice remained in the northern part of the Baltic Sea.

The snow pellets in Finland were formed in shallow cumulonimbus between 1.5–3 km, with temperatures ranging from -10 to -20 ºC at the base and top, respectively.
